COSTING AND ENGINEERING ECONOMIC ANALYSIS

EXECUTIVE SUMMARY The costing and engineering economic analysis report aims to:

• Combine the costing of all the elements of the proposed development of the MMTS-2 into one comprehensive report.

• Select the most favourable scheme option through an economic analysis over the assessed

lifespan of the project. The economic parameters used in the analysis process were:

1) The URV value which is the ratio between the present values of the cash flowed costs

and the volume of water delivered to the Mgeni System. 2) A discount rate of 8%.

3) An assessment lifespan of 45 years.

The scheme configuration assumes that the MMTS-1 development has been completed and commissioned. It is further based on the assumption that the infrastructure of the MMTS-1, especially the rising main and gravity main, will be fully utilizable over the assessment period for MMTS-2. This means that the pipelines, although older than the age at which they would normally be replaced by DWAF standards, will be kept in operation till 2065 without additional cost to the MMTS-2 scheme. The costing process assembled and estimated two types of cost:

- Once off capital expenditure to construct the Spring Grove Dam and transfer infrastructure as well as engineering and social and environmental mitigation costs.

- Annual cost for electricity, maintenance team remuneration and maintenance of the

scheme components. The analysis assessed a base case layout for the MMTS-2 consisting of:

• A 1.2 MAR Spring Grove Dam on the Little Mooi River. • A 4.5m3/s installed capacity pumpstation at the dam. • A new rising main to Nottingham Road. • An additional break pressure tank at Nottingham Road.


Costing and Engineering Economic Analysis Page iii January 2004 I:\3889\Documents\Feasibility Report\Report 6_Costing\Costing and Engineering Economic Analysis_January 2004.doc

• An additional gravity main from Nottingham Road to the Mpofana River. • An improved river outlet into the Mpofana River.

Three alternatives were derived by relocating the break pressure tank to a more hydraulically correct position and/or following a new shorter route between Nottingham Road and the Mpofana River. The planning dates for the scheme was based on the demand projections for the Mgeni River System on a medium and high projection basis. The available water for transfer from the Mooi River to the Mgeni System via the Midmar Dam was predicted as follows for the various stages of development of the Mooi River System.

SCHEME PHASE ANNUAL YIELD IN MGENI SYSTEM WITH 99% ASSURANCE OF SUPPLY

Pre MMTS-1 310 million m3/a

Post MMTS-1 345 million m3/a


From the demand forecast for the Mgeni System it was predicted that a shortfall in supply will occur in 2015 on the high demand curve or 2020 on the medium demand curve after the implementation of the MMTS-1. These dates were used as the planned implementation dates for the MMTS-2. Since the MMTS-1 infrastructure cannot by fully utilize all year round due to a shortage of available water for transfer from the Little Mooi River via the Mearns Weir, a further option for MMTS-2 was added whereby the Spring Grove Dam is built as Phase 1 and the spare capacity of the MMTS-1 transfer infrastructure is used to transfer available yield from the Mooi River as well. The Spring Grove pump station is then phased in as Phase 2 when the transfer capacity is outstripped by the demand and available yield. This situation is forecast in 2029 on the medium demand and 2022 on the high demand projections respectively. Based on this alternative scheme configuration, planning dates and cashflow expenditure and the calculated URV values, it was concluded that the preferred MMTS-2 development will consist of: Phase 1 :

• A 1.2 MAR Spring Grove Dam with FSL of 1433.5 m.a.s.l. • An additional gravity main of 600mm diameter steel pipe from Nottingham Road to the existing

location on the Mpofana River along the existing servitude. • A new second outlet structure on the Mpofana River. • A fish barrier above Inchbrakie Falls dependent on the recommendations of further

environmental studies.

Phase 2:

• A 4.5m3/s installed capacity pumpstation at Spring Grove Dam. • A new 1400 mm diameter steel rising main to Nottingham Road. • A new break pressure tank in the optimal hydraulic location at Nottingham Road to serve

MMTS-1 and MMTS-2. The cost and URVs for this scheme configuration as well as the planned implementation dates on the medium and high demand projection are:

1. INTRODUCTION/OVERVIEW

The costing and engineering economic analysis report aims to achieve the following objectives: • Combine the costing of all the elements of the proposed development into a

comprehensive cost report. • Provide an economic assessment of the project through an analysis of the capital cost,

the operation and maintenance cost and associated project management costs (e.g. engineering, administration and social and environmental expenses) over the expected life span of the project.

The economic analysis is done using the Present Value (PV) methodology which calculates the present value of cash flow expenses and revenue (sale of water delivered) over the analysis period of 45 years at the so-called “social discount rate” of 8% (this rate is determined by the Department of Finance for the RSA as a whole and takes into account factors such as foreign loans, interest rates, repayments of national loans, economic growth rate, inflation, etc.). Both the analysis period and discount rates are as per the guidelines from DWAF for the analysis of schemes on engineering economic grounds. The reporting unit is the unit reference value (URV) which consists of: URV = PV of Costs (Rmillion) PV of water delivered (million m3) The report confines the economic analysis to the recommended development options from the relevant supporting reports viz: • A 1.2 MAR Spring Grove Dam with a full supply level (FSL) of 1433.5 m.a.s.l • A 4.5 m3/s pump station at Spring Grove Dam • A new rising main from the dam to Nottingham Road • A new break pressure tank at Nottingham Road • A new additional gravity main from the break pressure tank to the Mpofana River along

existing servitude • An improved/new outlet structure on the Mpofana River • A fish barrier above the Inchbrakie Falls

Details of and the rationale behind the recommended option are contained in Supporting Report No’s 1 and 3 of this suite of study reports, i.e. the Water Resource Analysis and Transfer Infrastructure Reports respectively.



2. PROJECT COSTING 2.1 COSTING OVERVIEW

As stated in Section 1 the URV is used as the comparison value to evaluate the engineering economic rating of the various schemes. The costs used for the calculation of the URVs are capital costs, project management costs (engineering, administration, environmental, etc.) and operation and maintenance (O&M) costs over the assessed lifetime of the scheme (45 years). These costs are either of once off capital nature or of an annual nature.

Typically the once off capital costs considered are:

- Capital expenditure during the construction period(s). - Replacement costs of pumps (after 15 years), pipelines (after 30 years). - Environmental mitigation costs e.g. the fish barrier, rehabilitation of

wetlands, replanting of scarce plant species, expropriation of land, compensation for property, etc.

- Re-alignment of infrastructure in the dam basin.

Typical annual costs are:

- Maintenance of the dam wall, mechanical items, pipelines, etc. of which the annual costs are expressed as a percentage of the original capital cost.

- Environmental monitoring and maintenance costs as per the EMP. - Energy cost of the pumping stations based on the average annual pump

utilization. - Remuneration of operational staff.

2.2 COSTING METHODOLOGY

In determining the cost of this multi-task study, it was necessary to ensure consistency of cost estimating across the full spectrum of the scope of work, especially because of the multi-track and multi-team approach adopted by the Client. To this end pro-forma costing models in the bill of quantity (BoQ) format were developed for each of the individual elements of the scheme e.g. dam, pumpstation, pipelines and other structures. The cost models were populated using the 80:20 principles to select the high cost construction items to be measured in the cost model with a percentage allowance being included for non-measured work of lesser value. The principles and formats developed as part of the “Vaal Augmentation Planning Study” (VAPS) by the Department of Water Affairs and Forestry were investigated and re-used where suitable in the preparation of the cost models and measurement techniques for this project. The following completed cost models with the measured quantities for each element are included in Annexure A of this report.



- Spring Grove Dam - Spring Grove Pump Station - Rising Main to Nottingham Road - Break Pressure Tank - Gravity Main to Mpofana River - Mpofana Outlet Structure - Fish barrier above Inchbrakie Falls

The quantities used in the cost models were taken off the feasibility level engineering drawings prepared by the relevant consulting teams. Detail discussions of the design of the selected options are included in Supporting Reports No’s 1, 2 and 3 of the suit of feasibility study reports and are not reproduced in this report. Likewise the rationale followed to calculate the rates e.g. sourcing of engineering materials, procurement strategies, etc. can be found in these supporting reports. The mitigating factors for the environmental issues are discussed in Supporting Report No. 4 together with the costs associated with these factors. The structure of the reports comprising the suite of reports is shown on page (i) of this report.

2.3 DETERMINATION OF CONSTRUCTION COST RATES

The construction cost rates used in this report have a common base date of April 2001. The rates used in the cost models were developed in two categories utilising the 80:20 principle for classification: • Major rates i.e. items of large quantity or high individual costs

- resource based costing methods were used to calculate rates from first principles using a database of relevant input cost in the categories of plant, labour and material.

• Minor rates i.e. low volume or low individual cost activity

- rates were drawn from historic or current projects of similar nature and size using appropriate escalation indices (CPI and PPI) to update them to the costing base date.

The database of input costs used to calculate the major rates included the prices of large value equipment envisaged for the project. Since these items are subject to exchange rate fluctuations to varying degrees depending on their imported content, budget quotations were obtained from prospective suppliers e.g. Sulzer for pumpsets, pumpset auxiliaries and motors, Hall Longmore for pipes and valves and Barlows for construction plant.

2.4 ADD ON COSTS

The cost models are structured to estimate the direct construction costs of each element of the scheme on the basis of estimated quantities and calculated cost rates. The rates used are not fully inclusive as they do not allow for contractors preliminary and general costs. This



expenditure was therefore estimated as a percentage add on to the direct construction cost. The percentages utilised, historically based on market related tenders, are:

• Large Civil engineering work - 30% • Pipe laying contracts - 15% • Small engineering work - 20%

The project will also attract engineering fees when the detail design and construction phases are entered into. These costs were again estimated as add on costs to the construction estimates at percentages of 5% and 10% respectively for the design and construction stages. The future phases of the project (after the feasibility study) are also likely to attract administrative and institutional costs. The exact structures to be set up to administer these phases are unknown at present, but historically large water related projects have incurred administrative and institutional fees amounting to 12% of direct construction costs. The comprehensive cost input to the economic analysis therefore includes an add on cost component of this magnitude. The accuracy level of the design and cost estimating process at the feasibility stage of the project is estimated at 80-90% and a contingency allowance is therefore imperative. The cost models therefore include a blanket add on contingency allowance of 10% of the estimated total project cost. The order in which the add-on cost percentages are added is significant to the total estimated cost per element. The sequence of calculation used is: 1) Measured Quantities and Rates 2) 10% Miscellaneous Items 3) Preliminary and General Cost at the appropriate percentage 4) Preliminary Works for construction e.g. access roads and construction services 5) 10% Contingency Allowance 6) Engineering Fees (15% total) 7) Administration Cost (12%)

The cost models included as Appendix A reflect these add on costs in more detail.

2.5 SOCIAL AND ENVIRONMENTAL COST

The expected social and environmental costs were determined and reported in Supporting Report No.4. Extracted from this report the estimated compensation costs to landowners affected by the basin and backwater areas of the Spring Grove Dam are summarised in Table 2.1 below.



Table 2.1 – Estimated Compensation Cost

Building/infrastructure detail Estimated purchase cost in April 2001 Rands

Land 5 461 113 Buildings/improvements 7 960 000 Boreholes 400 000 Telephone lines 56 864 Fencing 1 633 486 Irrigation pipelines 2 110 927 Power lines 3 171 979 Pipelines 1 686 586 Roads 429 159

TOTAL 22 910 114

The above costs are based on the available database of land and property that will be inundated by the development of the Spring Grove Dam. Typical purchase rates were used for each category of land and improvement. During the pre-construction phase a more detailed evaluation of individual properties will have to be undertaken by a qualified land evaluator to verify and update these cost estimates. The compensation cost is included in the cost models spread over the 5 year pre-construction and construction period of the Spring Grove Dam. Supporting Report No.4 further outlines certain additional environmental activities to be conducted during the pre-construction, construction and post construction phases of the project. The expected expenditure on these activities, estimated in April 2001 Rands, are:

• Pre-construction period - R1 665 000 • Construction period - R 320 000 • Post construction period - R 550 000

The cost is included in the cost models over a period of 16 years commencing one year prior to the start of the engineering stage. The cost of some activities during the construction period could however not be evaluated during this study as they are dependent on the finalization of the Environmental Management Plan (EMP) and further studies earmarked for execution during the pre-construction period. The value of these activities is however expected to be relatively small and constant for all options under review and will therefore not have a significant influence on the economic analysis of the total project.



2.6 RELOCATION OF EXISTING INFRASTRUCTURE

The area inundated by the Spring Grove Dam at the selected FSL of 1433.5 m.a.s.l, including the backwater areas, will impact on a number of existing infrastructure elements. The costing process estimated the financial impact of mitigating these impacts as follows: Table 2.2 : Cost of Mitigating Impacts on Existing Infrastructure

The Eskom power line will have to be re-routed by Eskom, but a budget quotation could not be obtained from this company, as they were unwilling to provide cost estimates for projects at feasibility stage.

2.7 OPERATION AND MAINTENANCE COST

The annual operating costs of the proposed phase 2 of the Mooi-Mgeni Transfer Scheme largely consist of electricity charges associated with the pumping station. In calculating this cost the following principles were adopted. • The operating rule used was that the pumps will be operated intermittently at their

installed capacity as and when water for transfer was available. • Eskom’s “Nightsave Tariff” for Rural Reticulation Networks was used. Eskom was

unwilling to provide more accurate tariffs for this specific project at this stage of its development.

The only other annual operating cost allowed for in the economic analysis is the remuneration of the operation and maintenance team. An amount of R450 000 per annum was estimated for a team consisting of: • Supervisor (1) • Operator (2) • Mechanic (1) • Electrician (1) • Assistants (2)

Maintenance cost was included in the economic analysis on an annual basis based on defined percentages of the capital costs. These percentages, supplied by DWAF, are listed in Table 2.3 Table 2.3 Annual Maintenance Costs as % of Construction Cost

Element Civil Mechanical & Electrical

Dam & Fish Barrier 0.25% 4.0% Pipelines 0.25% 4.0% Pumpstation 0.5% 4.0%

The mechanical equipment at Spring Grove pump station will require periodic replacement due to operating wear and tear on the moving parts. Replacement cost for the equipment was estimated as a periodic cost set at 15% of the pumpstation construction cost at 15 year intervals. The equivalent cost for pipelines was set at the replacement of the pipes at 30 year intervals. Both the maintenance and replacement cost allowance are as per the DWAF guidelines.

2.8 SUMMARY OF PROJECT CAPITAL COST

As outlined in the foregoing sections, detail estimates of the individual once off capital cost estimates and annual maintenance and operating cost of the elements in the project are available in the Supporting Reports No’s. 2, 3 and 4 of the suite of feasibility study reports. These reports include the details of the estimating processes followed as well as the descriptions of the element components. This report does not reproduce all this relevant information. The costs of a base case and three alternatives are tabulated in Annexure C. These cases, as described in more detail in Supporting Report No. 3, consist of: • Base Case - a 1.2 MAR dam at Spring Grove (FSL 1433.5 m.a.s.l)

- a pumpstation at Spring Grove with an installed capacity of 4.5 m3/s

- a new rising main to Nottingham Road - a duplicated break pressure tank in the position shown in the

original design of the Mearns emergency scheme - a new additional gravity main along the existing servitude - an upgraded Mpofana outlet structure - a fish barrier structure upstream of Inchbrakie Falls

• Alternative 1 - a new combined break pressure tank in a new location at

Nottingham Road to improve hydraulics over the two tanks in the Base Case



- changes to the existing and new rising mains as well as the gravity mains due to the new location of the break pressure tank

• Alternative 2 - a new combined break pressure tank at the existing break pressure tank location in Nottingham Road

- a new gravity main to a new outlet upstream of the current outlet on the Mpofana River

- a new outlet structure on the Mpofana River - improvements along the additional stretch of Mpofana River

• Combined Alt - a new single break pressure tank at the new location of Alt 1

1 & 2 - a new outlet on the Mpofana river with the associated shorter gravity main of Alt 2 - alterations to the existing rising and gravity mains as per Alt 1 - improvements along the additional stretch of Mpofana River as per Alt 2 Table 2.4 OVERLEAF tabulates the total project capital cost for the Base Case. The total project cost for this option is R270.54 million inclusive of engineering fees and VAT at 14%. The costs for the 3 alternative options are R276.59 million, R266.75 million and R272.23 million respectively for alternative 1, 2 and combined 1 and 2. Details are included in Annexure C. The detailed cost models supporting these totals are included in Annexure A and the amounts

serve as input data to the economic model discussed in Section 3 of this report.

3. WATER DELIVERED (PROJECT REVENUE)

The URV tool chosen for the engineering economical comparison of the conceptualized MMTS-2 scheme requires that the present value (PV) of the total volume of water delivered over the assessment period be estimated. The Mgeni system demand projection graph included in Section 4.1 of this report gives the annual yields at 99% assurance of supply based on stochastic methods of calculation for the Mgeni System. The yield values at the various phases of development of the MMTS are:

4. ECONOMIC ANALYSIS 4.1 IMPLEMENTATION PROGRAMME AND PERIOD OF ANALYSIS

The revenue from this project will consist of water sales to the Mgeni System water users. These are made up primarily of the eThekwini Municipality (previously referred to as Durban Metro) which is by far the largest consumer of water from the system. eThekwini Municipality introduced a water demand management (WDM) programme in 1998 to reduce the water consumed by the users under their jurisdiction. Umgeni Water combined the water demand forecast from the Mgeni System with the predicted yields from the proposed Mooi-Mgeni Transfer Scheme phases 1 (MMTS-1) and 2 (MMTS-2) into a comprehensive water demand projection figure for the Mgeni System (March 2003) included here as Figure 4.1. Since the introduction of MMTS-1 the demand projections of the Mgeni system changed considerably on an annual basis due to eThekwini Municipality’s achievement with their WDM programme. This made it very difficult to time the MMTS-2. It is however, considered that the March 2003 projections are sufficient to do a comparative economic analysis to identify the preferred scheme configuration from an economic perspective. Thus the timing of the MMTS-2 assumed here should by no means be considered as an accurate date to implement the scheme. The actual implementation date will be determined from annual Water Resources Planning Model runs performed on updated demand projections. This figure includes:

• The historical water use for the years 2001-03 • The forecast water demand till 2024 on a high, medium and low demand

projection. • The estimated stochastic system yield from the MMTS prior to the introduction of

phase 1 - (310 million m3/a). • The corresponding estimated stochastic system yield after the introduction of

MMTS-1 - (345 million m3/a). • The estimated stochastic system yield with MMTS-2A (396 million m3/a) and

MMTS-2B - (406 million m3/a). • The estimated stochastic yield values are all at a 99% assurance of supply level.

The MMTS-2A and 2B scheme configurations referred to comprise:

• MMTS-2A : The construction of the Spring Grove Dam and the utilization of the full pumping capacity of the existing pump station at Mearns to transfer the available yield from the Mooi and Little Mooi Rivers until the demand outstrips the pumping capacity.

• MMTS-2B: The construction of the Spring Grove Pump Station to transfer the available yield from the Mooi River and utilization of the Mearns Pump Station to transfer only the Little Mooi River yield.



The figure indicates a shortfall between the supply from the MMTS-1 and the Mgeni System demand at a 99% assurance of supply level as follows: Table 4.1 : Predicted Time when Shortfall in Supply to Mgeni Users will Occur

Demand Projection Predicted Year when Shortfall will Occur

High Demand 2015

Medium Demand 2020

Low Demand 2031

This report assumes that the analysis will be done for both the medium and the high demand curves. The medium curve assumes the start date of delivery for augmentation of the Mgeni System from the MMTS-2 scheme as 2020 and the high demand curve assumes the start of delivery as 2015. It must however again be stressed that these dates are highly dependant on the successes or otherwise of the WDM programme of the eThekwini Municipality and may change accordingly. As stated in the Main Report of the suite of feasibility report documents, lead in times are required to implement the MMTS-2. These are:

1. Two years for appointment of consultants, for detail design, and for compilation of tender documents and the appointment of a contractor as well as for arranging financing.

2. A two year dam filling period for the Spring Grove Dam.

Taking cognizance of the above as well as the forecast construction durations for the various elements of the MMTS-2 the following abridged construction programme is used in the economic analysis process: Table 4.2: Abridged Implementation Programme for MMTS-2 (in one phase)

Allowing for the lead in time of two years to appoint consultants, complete the commercial tendering process and appoint a contractor, the process to implement MMTS-2 in one phase will have to be commenced at the start of 2013 (Medium Demand) or as early as 2008 should the High Demand projection be realised. However, should a two phase process be followed as per the phases (MMTS-2A and MMTS-2B) described above, the Spring Grove Dam and Fish Barrier (if required) will still have to be constructed as per the time table in Table 4.2 (2015-2017), but the remaining elements will only be constructed to be completed in 2028 for first water delivery from MMTS-2B in 2029, should the Medium Demand projection be used or in 2021 for delivery in 2022, should the High Demand projection be realised.

4.2 ASSUMPTIONS CONCERNING MMTS-1 INFRASTRUCTURE

The two phase approach assumes that the infrastructure from MMTS-1, i.e the refurbished Mearns pumps as well as the existing rising main, break pressure tank, gravity main and outlet structure into the Mpofana River will be serviceable until 2028 without above normal repairs or replacement. This implies that the rising and gravity mains will not have to be replaced before 2028 although both will be older than the prescribed 30 years after which pipelines are normally replaced as per DWAF guidelines for economic analysis. These pipes were installed in the 1980’s. This report is however based on the assumption that the pipes are in very good condition as a result of the very low and intermittent usage in the past. Neither does it include the pump replacement cost after 15 years of usage as this cost is deemed to have been included in the analysis of MMTS-1. Likewise the economic analysis for MMTS-1 should have included the annual maintenance cost and operational staff expenditure to operate the scheme for water transfer from the Little Mooi River. This economic assessment therefore only includes the differential pumping cost (energy cost) between the different transfer volumes of MMTS-1 and MMTS-2 during the period that the



infrastructure is also used to transfer Mooi River yield in the two stage approach (2020-2029 or 2015-2021 for Medium and High Demand projections respectively). The analysis period for the MMTS-2 was set at 45 years as per DWAF guidelines. This means that the analysis period considered is from 2020 to 2065 for the medium demand scenario and from 2015 to 2060 for the high demand scenario irrespective of whether a one or two stage implementation approach is adopted.

4.3 ANALYSIS MODEL 4.3.1 Selection of Model and Parameters

The consulting team assembled by DWAF to do the Study for the VAPS had to consider a large number of alternative schemes to augment the water supply to the Vaal River System, each with its own capex, implementation duration and maintenance and operational costs. This team, in consultation with DWAF, concluded that the most meaningful factor to compare the capital cost and returns of the various schemes was the Unit Reference Value (URV). This factor is calculated by: • Determining the present worth of all costs over the assessment period in R x million. • Determining the present value of water delivered in million m3/a. • Dividing the present worth of costs by the present worth of water delivered for each option

to obtain a URV in cents/m3. This factor is used as an economic comparison of the various schemes being considered with the lowest URV representing the most economical option. It provides a basis for evaluation but does not reflect the actual unit cost of water transferred. It is also only usable if the construction period of the schemes start at the same time. The economic analysis model developed during the VAPS to calculate the URVs was selected as the instrument to compare the five options recommended for the Spring Grove Dam and transfer infrastructure detailed in Section 2.8 of this report. The model required a number of modifications to ensure compatibility with the physical components of the scheme, the base date for comparison and the characteristic add on costs discussed in Section 2.4. The original model for the VAPS was designed to allow up to four phases of the scheme under consideration. Since the MMTS-2 essentially consists of only one phase the calculation sections for the other phases were left blank except for the option where the Spring Grove Dam and the associated new pump station and pipelines are not constructed in one phase. The model is based on the comparison of the present worth of costs and present value of water delivered and therefore requires a discount rate (%). In the case of this study the “social discount rate” of 8% (average) prescribed by the Department of Finance was used in consultation with the DWAF and UW. This rate is determined for the country as a whole and takes into account for example:

• Impacts of foreign loans

• Interest rates



• Repayment of national loans

• Economic growth rate of the country

• Inflation, etc.

This rate is not fixed and may change as these parameters do. DWAF therefore requires that the URVs be calculated for discount rates 2% above and 2% below the average rate to test the sensitivity of the URVs to changing discount rates. The analysis in this report is therefore done for 6%, 8% and 10% discount rates.

4.3.2 Input Data and Distribution Factors

The capital expenditure (capex) estimated for each option was entered into the model for each element of the scheme (e.g. dam, pipeline, pumpstation, etc). In each case the cost per discipline was entered separately to allow differentiation in the maintenance cost calculation. Social, environmental and engineering costs were entered separately and distributed as per the relevant parameters discussed below. Operational costs were split between the costs of electricity and the costs of the operational and maintenance team. Details of these costs and distribution factors appear on the Input Page of the models included in Annexure B. The annual distribution factors and implementation parameters used for the capex and O&M cash flow are outlined in Table 4.3. Table 4.3 : Capex Cash Flow Distribution Factors and Parameters

Spring Grove Dam 3 years 20% up front, remainder evenly distributed over 3 years.

4.4 RATE AND VOLUME OF WATER TRANSFERED

Water would be transferred from the Mooi River System to the Mgeni River System as determined by the demand from the latter. It was not part of the scope of work of this study to determine the historical and forecast demand curve of the Mgeni River System, but the demand curves supplied by Mgeni Water and included as Figure 4.1 were used in the analysis. The stochastic system yields of the various stages of development of the MMTS are used in the economic assessment. These values, as shown graphically in Figure 4.1, are:

Stage of MMTS System yield in million m3/a Incremental yield in million m3/a

Pre MMTS-1 310 -

Post MMTS-1 345 35

Post MMTS-2A 396 51

Post MMTS-2B 406 10

These figures are based on an operating rule of: • Intermittent pumping at full capacity if transferable water is available. • A 70% decision level at Midmar Dam. These numbers correspond with Scenario 4.1 as described in the Main Feasibility Report. The three pump sets at Spring Grove Pump Station were introduced sequentially as determined by the increased demand as per the curves in Figure 4.1.

4.5 RESULTS OF THE ECONOMIC MODEL ANALYSIS

The configurations of the MMTS-2 options considered in this report are summarised in Table 4.5:

Table 4.5: Configurations of Options of MMTS-2

OPTION CONFIGURATION

Single Phase:

Base

1, 2 MAR Spring Grove Dam – FSL 1433.5 m.a.s.l.

Spring Grove Pump Station – 4.5 m3/s installed capacity.

A new rising main to Nottingham Road – 1400mm dia.

An extra break pressure tank at Nottingham Road.

A new additional gravity main along existing servitude – 600mm dia.



OPTION CONFIGURATION

An upgraded outlet structure into the Mpofana River.

A fish barrier above Inchbrakie Falls*

Alternative 1 As per the Base Option but with:

- A new single combined break pressure tank at Nottingham Road in the optimum hydraulic position.

- Associated pipework changes to rising and gravity mains.

Alternative 2 As per Alternative 1 with:

- A re-aligned route for the new additional gravity main to a position upstream of the existing outlet in the Mpofana River.

- A new outlet structure into the Mpofana River.

- Upgrading of the additional stretch of the Mpofana River.

Alternative 1 and 2 combined

As per Alternative 2 but with:

- A new single break pressure tank in the most optimal hydraulic position as per Alternative 1.

- Associated pipework changes to rising and gravity mains.

Two Phases

Phase A

- Spring Grove Dam

- Fish Barrier

- New additional gravity main and improved outlet into

Mpofana River

- A new break pressure tank

Phase B - A new Spring Grove pump station

- A new rising main to Nottingham Road

* The fish barrier above Inchbrakie falls is included in the analysis although it may not be required in this configuration. The need and configuration will be determined by later environmental studies closer to the time of implementation of MMTS-2. The input data, calculation sheets and output data of the models run as part of this analysis are included in Annexure B.

The options analysed do not have significant variances as far as construction content and therefore capital cost are concerned. As can be expected the resultant URV’s for the first four



are also comparatively close. However, a clear advantage emerges when the infrastructure is constructed in a phased approach. This option uses the Mearns pumping capacity to its full capacity before the Spring Grove Pump Station is constructed and commissioned.

4.6 SENSITIVITY ANALYSIS

Two factors have been considered to test the sensitivity of the economic analysis: • Variance in social discount rate • Time scheduling of the project. The economic model assesses the input data against the selected three discount rates of 6%, 8% and 10%. The comparative URV’s are included as Table 4.6. Table 4.6 – Comparison of URV’s at Various Discount Rates

URV’s (c/m3) for different rates and demand scenarios

Medium Demand High Demand Option

6% 8% 10% 6% 8% 10%

Base Case – Single Phase 46 63.8 86.8 45.9 62.9 84.5

Alternative 1 – Single Phase 46.7 64.9 88.3 46.6 63.9 85.8

Alternative 2 – Single Phase 45.2 62.8 85.4 45.3 62.2 83.5

Combined Alternative 1 and 2 45.2 62.8 85.5 45.9 63.1 84.8

Phased Alternative 1 – Two Phase

41.4 56.8 76.6 42.4 57.2 75.6

The two phase Alternative 1 emerges as the more favourable configuration at all three discount rates. No change in order occurs for the medium demand at the other discount rates. At the higher demand the base and combined Alternatives 2 & 3 trade places for 3rd and 4th places at 8% and 10%. The differences are however very subtle and it must be concluded that the URV’s are not sensitive to change in discount rates. The timing of the implementation of the project is largely dependent on the water demand management programme introduced by the Durban Metro (now eThekwini Municipality). Meteorological factors can also affect the need for the further augmentation of water supply to the Mgeni System should a particularly dry cycle occur. These factors cannot be predicted accurately and the required implementation date of the MMTS-2 may therefore have to be altered on both sides of the currently envisaged 2020 for the medium demand curve or 2015 for the high demand curve projection. No mechanism exists to compare the schemes with different starting dates as the URV cannot be used in such cases. It is however significant that the phased approach represents a 10% advance over the second placed option at both the medium and high demand projections.

From the foregoing the following conclusions are drawn: I) The available water in the Mgeni System after implementing MMTS-1 will be

insufficient to supply the demand at a 99% level of assurance by 2020 using the medium demand curve and 2015 if the high demand curve is realised.

2) The proposed MMTS-2 scheme will be able to augment the supply to meet the

demand till 2032 when further augmentation from another source is required based on the medium demand curve. (2024 on the high demand curve).

3) The phased introduction of the infrastructure in two stages is the most economical

approach.



4) The economic analysis is insensitive to fluctuations in the discount rate.

5) The need to construct a fish barrier upstream of the Inchbrakie Falls must be determined prior to Final Design Stage. The decision to include or exclude the fish barriers will however not change the findings of this report because it is a common factor in all scheme configurations considered in the economic analysis.

It is therefore recommended that the MMTS-2 consisting of the following elements be constructed to be completed by the stated commissioning dates, based on the medium demand projections (dates in brackets represent the high demand projections): Phase 1:

• A 1.2 MAR Spring Grove Dam and fish barrier by 2017 (2013) • An additional gravity main along the existing servitude (600mm diameter, 7875m

long) by 2019 (2014) • A new second outlet on the Mpofana River by 2019 (2014)

Phase 2 :

• A 4.5m³/s installed capacity Spring Grove Pump Station by 2028 (2021) • A new rising main (1400mm diameter, 6280m long) from Spring Grove Dam by

2028 (2021) • A new break pressure tank at Nottingham road by 2028 (2021)

The estimated capex to construct this scheme including the environmental and social mitigation cost is R235.2 million in April 2001 Rand terms. This amount excludes VAT, engineering fees and land purchase costs. Operating and Maintenance costs over a 45 year lifespan are estimated at approximately R179.2 million on the medium demand projections or R183.2 million on the high demand projections.
