12 Tunisia 2012 State of the Water Report

MEW

INA

1. IntroductionThis report is conducted in the framework of MEWINA project in execution of the component relating to the standardization and harmonization of national systems with those of N-AMCOW and the development of a sustainable mechanism for monitoring, evaluation and reporting.

After the development of a minimum set of indicators, standards and criteria; of a framework and operational guidelines of the state of the national water monitoring and evaluation, and after the compilation of existing data and information on the monitoring and evaluation of the water sector and sanitation; it is important to continue the process and prepare the National Baseline Report State of the water for the country. This methodological guideline will not only monitor progress and performances achieved in the country to meet the objectives of national, regional and global targets in the water and sanitation sector, but also will prepare Baseline State of the Water Report in the N- AMCOW region.

Although efforts have been made in the country for the reporting of monitoring and evaluation of water sector, this National Baseline State of the Water Report proposes to bring together existing indicators, process, and integrate the most useful and the most relevant of them with the SOW indicators harmonized regionally by the MEWINA project, to stop a new set of indicators to be regularly monitored and evaluated in the country in harmony with the SOW indicators in N-AMCOW region.

The first part focused on nationally set water related targets in Tunisia, as well as continental and global targets that have been adopted. The current standings towards achieving all targets were mentioned. In addition, values were assigned for the target indicators presented.

The second part presents the full list of indicators used in the report and all indicators belong to one of the agreed indicator categories, during the MEWINA Water M&E Rapid Assessment Regional Validation Workshop held in Cairo on October 27th-29th 2013. Definitions, methodologies of calculation and reporting, institutions in charge of measuring and/or estimating indicator, and source of data were outlined in this section as well.

The following section consists of a data sheet indicating the values assigned to each indicator, for the year 2012, along with the units of measurement, the measurement year, the source, and any remarks.

Then, an overall analysis of the national state of the water is provided and an inventory of available historical data for some indicators and observed trends is given.

Finally the last part recommends policy reforms to enhance the state of the water Reporting process in general.

Green Water:

Green Waters cover rainwater intercepted by: (i) rain-fed agriculture (field crops and dry agriculture), (ii) forests and rangelands. The covered areas are:

• Field crops: 1,764,500 ha:• Cereals: 1,244,000 ha• Fodder: 436,000 ha• Leguminous: 84,500 ha

• Dry arboriculture: 1,995,000 ha• Olive trees: 1,549,000 ha• Olive and almond trees intercropped: 165,000 ha• Olive and fruit trees intercropped: 69,500 ha• Vineyards: 18,500 ha• Almond trees: 193,000 ha

• Forests and Rangelands: 5,505,800 ha• Forests: 666,300 ha• Rangelands: 4,326,000 ha• Alfa and halophyte plants: 513,500 ha

Green water is calculated on the basis of annual plant needs. These needs are generally satisfied when the annual rainfall for the current year is equal to or greater than the average annual rainfall in the country, and well distributed in time and space. The areas indicating field crops and dry arboriculture are derived from the annual survey on monitoring the crop season developed by DGEDA (Agricultural sector indicators, January 2012), while the area covered by forests and Alfa grass are the responsibility of DG Forestry. The assumptions considered in the survey are: (i) the max, min, and average plant needs.

8. Water & Quality:

Institutions that ensure monitoring and evaluation of water quality are: (i) DGRE (BIRH) for the quality of natural water through its network (TDS, nitrates), (ii) SONEDE for physico-chemical and bacteriological quality of drinking water (50 000 samples /year), (iii) DHMPE also performs control operations on public wells and water supply networks (residual chlorine and bacteriological analyzes) on drinking water, wastewater, and treated wastewater (total of 50 000 samples / year), (iv) ONAS for water at the entrance and exit of its WWTP, (v) and ANPE for controlling water pollution (COPEAU) in receiving environments.

The 2012 data were drawn from the 2012 annual report of ANPE related to the network of monitoring water quality in Tunisia, being edited.

This network is composed of water sampling stations, installed on: (i) three watersheds (wadi Medjerda, wadi Miliane and wadi El Bey), (ii) three lagoons (Bizerte, Ghar El Melh and Halg El Menjel) (iii) sebkha of Korba, (iv) wadis and dams in the north of Tunisia, (v) and groundwater resources. This network has undergone modifications and extensions in recent years. At least two sampling campaigns are conducted annually and the results are published in the corresponding directory.

Regarding the bacteriological analysis, SONEDE conducted in 2012 bacteriological analysis of 48,251 samples. Different analyzes have resulted in an average percentage of 98.5% suitable cases.

The table below summarizes the evolution of sampling and bacteriological analysis for the period (1995-2012):

The average percentage of cases unsuitable for all Tunisia, at 1.5% in 2012, is still below the limit required by the NT 09.14 and 5% threshold tolerated by the World Health Organization standard.

In Tunisia, the wetlands support 260 terrestrial plant species, 50 aquatic plant species and 140 bird species, most of which are migratory. Wetlands host annually in winter, more than 500,000 birds from Asia and Europe. For example, Tunisia is home to an annual average of 250,000 ducks and coots in January, 58% of the Maghrebian population and 25,000 flamingos, one-third of the Mediterranean population.

Water& Ecosystems indicators (2012) are:

of water used to produce a certain product can be estimated by multiplying these reference values (or any similar values provided in the national and global literature) by the total annual produced amount of the same product. In the same manner, it is possible to estimate the amount of water embedded in imported and exported products

13. Water & Governance:

- Physical Domestic Water Losses:

Water losses:

Water losses are either, visible (commercial) losses or actual (physical) losses. It is for this reason that the IWA uses the concept of volume not sold or unbilled water: Non Revenue Water (NRW) in establishing water balance. The concept of Water Not recorded (unaccounted For Water: UFW) is increasingly neglected also because of the confusion it could generate as a result of different interpretations.

Apparent water losses or Commercial losses (CL): is the volume of water consumed but integrated into losses due to measurement errors (imprecision meters) and consumption diverted (fraud).

Actual water losses or Physical losses (PL): is the volume of effective water loss from service to the subscriber meter. They cover all types of leaks (pipes, connections), pipes rupture, overflowing tanks, etc…

The losses distribution on SONEDE water supply networks in 2012 is recorded as follows:

• Overall Water Use Efficiency: 100* ((Withdrawals from Original Sources- Wastewater and Drainage outflows) / Withdrawals from Original Sources)

Withdrawals from Original Sources= Withdrawals from surface water, renewable and non-renewable groundwater, and desalinated water = 0.615 + 1.511 + 0.610 +0.030 = 2.766 BCM in 2012

Wastewater and Drainage Outflows: Wastewater and Agricultural Drainage flowing out of the system= (0.232- 0.060) + (0.140 – 0.020) = 0.292 BCM in 2012.

Overall Water Use Efficiency: 100*(2.766 – 0.292)/ (2.766) = 89.5 % in 2012.

Source: DGBGTH, DGRE, DGGREE, SONEDE, ONAS

• Water Sustainability/ Depletion Index: is the ratio of the Total Withdrawals from Original sources including green water consumptions by rainfed agriculture to The Total Renewable Water Resources (Blue and Green Water).

TSI = (2.766+ 5.5)/ (4.084+ 13.000) = 48.4 % in 2012.

Source: DGBGTH, DGRE, DGGREE, SONEDE, ONAS.

• Number of Water Users Associations: 2580 Groupings of Agricultural Development, composed of: 1327 WUA (GAD) for Water Supply and 1253 WUA (GAD) for Irrigation

• Water Users Associations Agricultural Land Coverage: 200,000 ha covered by Irrigation WUA, representing 47, 5% of Irrigated areas (421,000 ha), and 1.0 % of Agricultural land (19,759,500 ha) in 2012.

14. Water & International Relations:

• Transboundary Water bodies’ dependency Ratio: the percent of annual volumes abstracted from transboundary water bodies to total annual available water resources.

Annual volumes abstracted from transboundary water body = (Total External Renewable Blue Water Resources Inflow) + (Withdrawals from NWSAS Blue Non Renewable Groundwater)+ (Withdrawals from Djeffara plain Groundwater) = (0.320+ 0.100) + (0.610)+ (0.149)= 1.179 BCM/Year

Total Annual Available Water Resources= 18.140 BCM/Year

TWBDR = (1.179)/ (18.140) = 6.5 % in 2012

• Shared Waters related Bilateral/ Multilateral Agreements and/or Memorandums of Understanding and Cooperation Mechanisms: Currently there is only the Concertation mechanism launched in

In conclusion, most values in 2012 are available except for indicators that are not monitored and evaluated regularly and for which there is still no institution in charge for their development and monitoring and where an institutional gap persists (Rural sanitation, Rainwater use).

It turned out that some additional specific indicators are not monitored regularly or require additional capacity for monitoring; these indicators will be monitored and evaluated regularly once capacity will be strengthened.

Data on Water & Finance indicators are confused and are not homogeneous (allocated credits, commitment appropriations, enrolled appropriations, payment, etc.).

NWSAS indicators are not representative, data are not significant and do not reflect the issue of NWSAS particularly governance and water policy

The historical data, despite their existence and their availability were not communicated in time by NTF members. Once received, they allowed us to be informed on the status of indicators, trends and possible reasons for their fluctuations.

endations

Tunisia 2012 State of the Water Report

MEW

INA

The existing system of monitoring, evaluation and reporting of the state of water, in Tunisia, despite its shortcomings and limitations, helps to the knowledge of the state of water and environment in the country. So that, it can fully play its role, and be in line with the efficient systems at regional, continental and global scale, it is necessary to improve, enrich, strengthen, expand and upgrade it. For this, we recommend the following reforms:

• Complete the development of Water Information System (SINEAU) and its various components to evolve as a decision support system that can be used on progress in water sector

• Construct information sub-systems (or DBMSs) within the related institutions that do not have them, to be integrated in SINEAU

• Lift the institutional gap of rural sanitation and rainwater management (use)• Enhancement of institutional arrangements• Establish departments or entities dealing with monitoring, evaluation and reporting of the status of

water in key institutions in charge of water, and reform the relevant legislative texts.• Implementation of M&E&R sub-systems in all the institutions in charge of water resources• Implementation of a national M&E&R system at the central level and appoint DGRE or BPEH of

its management• Improving Monitoring process• Implementation of a dissemination and awareness strategy• Capacity building and strengthening training program• Establish a MEWINA unit within DGRE or BIRH.

2. Basis of the existing water sector Policy/ Reform and potential policytargets.

Important issues addressed in the existing Water Sector Reform?Public policy of water in Tunisia was established based on the following strategic objectives: (i) ensure the supply of drinking water to all inhabitants (ii) develop tourism and ensure food security of the country by restricting imports of food and agricultural products and by encouraging the export (iii) stabilize rural incomes. Actually other objectives are added such as improving the efficiency of irrigation systems ensuring better use of water resources. Thus the objective sought by the state is that the share of irrigated agriculture in the national production passes from 35% to 50%. These policies have gone through two major steps that led to a switch from a policy based on the sustained mobilization of water resources in order to improve the supply, to a policy of management and valorization of these water resources in order to manage the global demand.Meanwhile the focus is more on finding unconventional resources. This research includes: (i) the reuse of treated wastewater, and to a certain extent, desalination of brackish and saline water, (ii) and integrated water resources management (IWRM).

The objectives of the new water policy in Tunisia seek to: (i) ensure continuing suitability between needs and water resources by increasing supply and controlling of the demand, (ii) identify imbalances at the scale of natural regions of the country (iii) consider ways to readjust imbalances in the context of integrated management.This evolving policy hasn’t ceased to be modernized and completed to address key issues and resulted in the development of national or sector strategies and action plans and programs to implement these strategies.

Major reforms in the water sector and sanitation:BPEH restructuring, revision of the Water Code, Renaissance of the National Council of water, review of legal, regulatory and contractual hydraulic groups framework, review of the Tunisian standard NT09-14 on the quality of drinking water; revision of the NT106-03 on the reuse of treated wastewater; workshop to launch the project development and implementation of SINEAU (26/03/2013), national Consultation Workshop on the review and analysis of the state of implementation strategies and / or action plans for wastewater in Tunisia (05/03/2013), water table on the water local management (25/12/2013), local governance legal framework of water in Tunisia (27/05/2014),consultation workshop on governance and financing of water sector (18/02/2014) ...

Main potential targets by 2016:(i) mobilization of 95% of water resources, (ii) the irrigated area using water-saving equipment reaches 93% (iii) 90% of the cost of water for irrigation systems and rural water supply is recovered (iv) efficiency rate of the parcel irrigated is 78%(v) accessibility to drinking water in rural areas is 98%

3. Knowledge of international and African Milestones on Water and Sanitation.

Which are the ones well known and used in the county? Specify how it is used.--The Millennium Development Goals (MDGs) adopted by the General Assembly of the United Nations (UN) in 2000,who declared the decade 2005-2015 as the Decade of Water for Life, target international goals in the sector of water and the environment. Goal 7 aims to preserve the environment, and by2015, the percentage of the population that does not have sustainable access to safe drinking water or to sanitation will be reduced to half its value now (target 7c).The rates achieved by the country in terms of water supply and sanitation are as follows:Accessibility to drinking water is 100% in urban areas and 93.9%in rural areas. For sanitation, the rate of access is 99% in urban areas and 84% in rural areas, which reflects the significant efforts made in this area.

-The shared African water vision 2025 aims that Africa have equitable and sustainable management of water resources for poverty alleviation, socio-economic development , regional cooperation and the preservation of the environment. The realization of this vision depends on four axes: (i) strengthening the governance of water resources, (ii) improving the efficiency of water usage (iii) meeting the urgent needs for water, (iv) strengthening financing of water in the future. These areas are broken down into 12 targets. For example, for axis3 target1, the African vision plans to reduce by 25% in 2005 and 75% by 2015 the proportion of people without access to safe drinking water and sanitation. The rate of inaccessibility to water and sanitation in Tunisia in 2013 was reduced respectively by 91.9% and 77.8% and are therefore in line with the objectives of the African Water Vision 2025. The efforts performed by Tunisia for the achievement of the vision targets meet the objectives in general.

-Sharm Elscheickh commitments to accelerate the achievement of water and sanitation in Africa, signed by the Heads of State and Government of the African Union, on the occasion of the 11th Ordinary Session of conference in Sharm Elscheickh, Egypt, from 30 June to 1 July 2008, these commitments are also considered for the monitoring of the progress to achieve the various targets.

5. Comments on the national water sector regarding the strengths, weaknesses, opportunities, threats and outstanding problems.

Water resources of the country are limited. In order to exploit and develop this potential, Tunisia has established the legislative framework and institutions necessary for the realization of ambitious programs on the water sector. It has developed policies, national strategies and action plans for the sustained mobilization, management, protection and enhancement of water resources. The important improvements mobilization, storage, transfer and handling produced water in recent decades, with the development of various sectors of the economy and significantly reduced the vulnerability to the vagaries of climate: water security, mitigation the effect of drought, protection against flooding. Tunisia raised the challenge of mobilizing her water resources to serve the socio-economic development and welfare of its population, so that the Tunisian now has a level of water comfort that has not been matched in the past. Today, Tunisia faces the problems of, effective management, integrated and sustainable conservation, resource protection and enhancement of its maximum, to meet growing demand, future needs and control risks.

The sector has achieved remarkable performance in terms of water supply and sanitation with a very positive impact on the quality of life and economic activity. Despite the achievements, the water sector still faces problems that hinder its proper functioning particularly in terms of monitoring and evaluation. Among these problems, we can mention : IWRM is still under development, the water stakeholders are not yet fully involved, ineffective management of groundwater, storm water is not used outside the agriculture sector ,pricing and the mismatch between the price of drinking water production and sales of, the institutional gap for rural sanitation ...

Similarly, the national information system on water (SINEAU) offers a dynamic database and a unified system to all sub systems management. However, monitoring and evaluation is still under development, and only some subsystems (SYGREAU, COPEAU) are operational. Also, governance needs to be improved or even enhanced by the introduction and application of the principles of good governance

PC. 4.2. Water-related Hazards

Specific actions taken so far for the milestone (water disaster prevention initiatives):There is a national committee to fight against natural disasters and to organize rescue efforts. There is also a regional committee for combating water related hazards in each governorate. These committees have operations manuals and plans for disaster preparedness and disaster management.

Target: Establish at least 1 Early warning System for disaster prevention at national level by 2015.

Existence of Early Warning Disaster prevention System and Year of establishment:o For the prevention and management of flood risks, the DGRE has put in place in 2008, a system to collect hydrological measurements in real time and announcements of flood in Tunisian wadis (SYCOHTRAC). This system allows the acquisition, collection, processing and dissemination of information in real time, enabling a quick decision during heavy rainfall and floods. It is a network of operational alert for a good understanding of climatic events, providing early warnings for the protection of property and persons against the devastating effects of extreme events. It includes :( i) a network of 130 automatic observation stations for measuring rainfall and water levels in wadis and dams, powered by solar panels. It is equipped with data acquisition system that stores collected information and transmitting the information via (GSM) modules with capture, storage

and transmission of data through the network mobile (GSM) (ii) eleven call centers and data retrieval based on the DGRE, DGBGTH, and the CRDA (iii) and a computer system (WINMONI) for managing the stations, alarming and gathering and validating the data in the data base SYCOHTRAC. The SYCOHTRAC is also a tool for decision support that allows the consultation and data visualization in real time. A software program (PHy) (rainfall, Hydrometry) allows the access to the database through the WEB technology via the intranet network (AGRINET) of MA allowing operators and decision-maker to: (i) check the database under tabular and / or graphical forms, (ii) editing the rainfall or hydrological sheets, (iii) and take immediate and adequate decisions.

o In addition, the AMU countries have established a Maghrebian observatory for the drought, which is a part of the drought early warning system (SMAS) project. The objectives are: the prevention of environmental degradation caused by drought, improving the diagnosis capabilities of the drought crisis and the development of adaptation strategies to reduce the impact of drought using an early warning system (EWS) allowing a regular monitoring of environmental change in the Maghreb countries, and strengthening institutional ability for early warning and drought risk management. The expected results are: (i) the production of indicators of structural and economic vulnerabilities in each country, (ii) the development of structural vulnerability maps, (iii) the integration of EWS products in development plans, (iv) and spreading of EWS products on the Web. The current monitoring tools for measuring the drought impacts, in Tunisia are: (i) meteorological indicators (compared to normal, deciles, or standard precipitation index SPI, reflecting periods of deficit and excess rainfall), agronomic indicators, socio-economic indicators, hydrological, ecological, and socio-economic (ii) remote sensing, (iii) and climate forecasts.

o Similarly, the DHMPE of the Ministry of Health is also working very hard at the prevention and management of health risks associated with water and the environment in case of natural disasters. Regarding the monitoring of the state of drought in different meteorological stations in the country, INM develops cards of Standard Precipitation Index (SPI); the mapping of this index shows the areas that are affected by drought.

-Elements of risk knowledge are: Sectoral studies, documents and guides exist as guide of the sustainable management of water resources, drought guide, and management of extreme climate change. They clarify the risks and provide appropriate responses and mitigation strategies to address a specific risk. Observation networks and monitoring of specific indicators and early warning systems help to know the risks.

- Elements of the Monitoring, analysis and prediction of risks: Monitoring, analysis and forecasts of the risks are conducted with a monitoring and information system.-Elements of the Communication or dissemination of alerts and warnings: Alerts and warnings are communicated or distributed according to an agreed communication strategy on risk management. All channels of monitoring and information can be used.

-Elements of local capacity to respond to the warnings received: There are emergency plans and supporting infrastructure at multiple levels.-Sources of verification and specific comments: national committee to fight against natural disasters and rescue organization and the regional committees in each governorate.

- Water Rights in the new constitution (Article 44) (2014)

Target: Institute/update, by 2015, water sector policy reforms that reflect good governance principles of:

-Existence of Water sector policy that reflects good governance principles, and Year of latest update:-The study of the water sector (1998) established the future strategic direction of the sector and laid the basis and the foundations of integrated water resources management (IWRM)The study recommends an integrated approach for the management of water resources and taking into consideration at the same time the management of groundwater and surface water, the management of the quantity and quality of water and the balanced participation between state and users. In addition, it recommends that while pursuing the mobilization of new water resources, a strategy of “demand management” should be conducted in order to reduce losses and protect the quality of water resources, improve the socio-economic effects for the use of water and to minimize environmental damage.

(i) Partnership commitment; (ii) ethics -transparency, equity and fairness; (iii) responsibility and accountability; (iv) inclusiveness, participation, predictability and responsiveness; and (v) coherence.

It seems that we are moving towards a future where allocations between the various water usages are optimized economically and the available water resources are used with an integrated manner. The principles and frameworks of management must ensure a transformation towards a sustainable and equitable solution for everyone.

The long-term strategic study of the water sector in Tunisia is based on the prediction of the resources for future mobilization projects and on the evolution of the demand for some socio-economic indicators...

Given the limited water potential of the country, the increased needs will lead to a rigorous and sustainable integrated management of the resource by:(i) searching for new resources, (ii) the use of non-conventional waters (iii) improving the efficiency of water infrastructure and water conservation (iv) the management of water quality, preservation of the resource and the protection of ecosystems and the environment, (v) mitigation of extreme events (droughts and floods) (vi) the optimization of data collecting systems , accessibility to the information for everyone and the development of a water information system (vi) the development of a public-private-partnership (vii) the implementation of legislation and strengthening the responsibilities of the water management institutions(viii) and the search for tools and appropriate , innovative and diversified funding

- PISEAU also aims to: (a) promote the integrated management of water resources by (i) the establishment and implementation of an institutional framework and implementation of sectoral reforms to adopt a management demand (changes in tariff policy, new institutional arrangements), (ii) improving the capacity of government, GIC and private sector operators to manage resources in an efficient manner, and (iii) better real-time management of surface and groundwater, and (b) promote the conservation of water resources and environmental protection. PISEAU 1 is based on the following investment components: irrigation management, rural water supply, groundwater management, conservation of water resources and environmental protection, and capacity building. PISEAU 2 continues the investment in the same components. It supports the strengthening of the monitoring networks of water resources, the establishment of the: SINEAU, monitoring system for soil quality and pollution control , groundwater management, the conduct of pilot operations on rural sanitation and improving the quality and value of treated wastewater.

- The study of the water sector and PISEAU also recommended that the governance of water and sanitation must be improved.

Governance is a complex process that involves the participation at several levels beyond the state.The water governance has four main interrelated dimensions: (i) a social dimension that is equitable use of the resource, (ii) an environmental dimension that allows sustainable use of the resource and ecosystem integrity, (iii) an economic dimension: efficient use of the resource, the role of water in economic growth, and (iv) a political dimension to ensure that all stakeholders, users and citizens have equal access to water opportunities.

The characteristics of good governance are: efficiency, sustainability, participation, accountability, integration, ethics, motivation, transparency, fairness, consistency, openness, and communication.The keys for a good governance are: political will and public-private partnership with respect to the needs and dignity, regulations for the quality of services, service providers efficient and accountable, good policies, effective institutional structures, and public participation.- Revision and amendment of the Water Code. Bill revising and implementing decrees (2010-2014)

The new Water Code deals with the objectives and general principles, delimitation and preservation of public water domain, governance in the water sector, regimes to use the water, uses and water utilities, prevention and risks related to water, regime control and monitoring, and transitional and final provisions.- Water Rights in the new constitution (Article 44) (2014)Article 44: “The right to water is guaranteed. The water preservation and the rationalization of its operating is the responsibility of the State and the society. “

Elements on Partnership and commitment: ONAS has already initiated activities in partnership with the private sector for the operation of sanitation facilities (network, pumping stations and treatment plants). The rate of private sector involvement in the operation of the infrastructure was 12% in 2005, rose to 16% in 2011 and fell to 13% in 2012 and 2013. Similarly SONEDE intends financing, building and operating sea water desalination plant of Djerba by BOT concession contract.Elements on Ethics - transparency, equity and fairness:existence of legislative and regulatory frameworks

Target: Set by 2015, water tariff system that addresses cross-subsidy and the need of poor.

Example for Indicator: Lifeline Water (l/ca/day): 100 Minimum salary of the population (TD/month): 319.9 For a hypothetical 5 persons family: water used = 100 l/c/d * 5 * 30 /1000= 15 m3

(minimum billed =20 m3) cost at 0.155 TD /m3 = 3.1 TD

% of minimum monthly income = 3.1/319.9 = 1 % < 3%

Target is met.Tariff Structure: The water tariff was adjusted 2 times in 2013. The first adjustment by decree of 13.06.2013 and the second by decree of 26.12.2013 (in force).

Consumption categories (m3/ quarter) Rate (local currency mls/m3 and USD/m3)

0-20 155 mls/m3 which is 0,09 USD/m3

21-40 270 which is 0,159

41-70 365 which is 0,216

71-100 665 which is 0,393

101-150 815 which is 0,482

151-500 1135 which is 0,672

≥ 501 1190 which is 0,704

Adjustments for cross-subsidy:

Adjustments Rate

Rural hydrants (Standpipes) 155 mls/m3 = 0,09 USD/m3

Tourism 1190 mls/m3 = 0,704 USD/m3

Fixed charges are in addition to this fee, the value is determined by the diameter of the counters: D15 (DT 4.400 / quarter), D20 (8.160), D30 (15.080), D40 (27.700), D60 and D80 (70.400), D100 (113.250) and D150 (295.000).This tariff reflects the equalization and access for the poor (social group) and encourages saving water.

Tariff for rural areas if any: Same price for Connecting Rural, while for the population served by hydrant, the price is social. Describe the sanitation services pricing if there is any:

Consumption categories (m3/quarter) Rate in millimes/m 3 and USD/m 3

>= 151 300 (0-70) then 606 (after 71)

Fixed charges (RF) to be added:• Tourism usage: RF = 8688 + 1080 mls/m 3

• Industrial usage and polluting activities: RF = 8688 + {617 mls/m 3: equipped & low pollution or 845 mls/m 3: average pollution or 845+410*Q mls/m3: heavy pollution}, Q = coefficient of pollution• Industrial usage not connected: {equipped and low pollution: 0 or polluter: RF = 8688 + 617 mls/m 3}• Administrative usage: RF = 8688 + 845 mls/m 3

• Other usages: commercial, professional or other: RF = 8688 + {Consumption <10 m 3/quarter: 574 mls/m 3 or consumption> 10 m 3/quarter: 717 mls/m 3}

Target: Enhance by 2016, the national water and sanitation Monitoring, Evaluation and Reporting (M&E, &R) Systems in a way to be in line with the pan African M&E.

Specific actions taken so far for the milestone: - launching of the development project and establishment of SINEAU 26/03/2013 in Tunis.

- Strengthening of the existing monitoring and evaluation and reporting systems to be in line with the Pan African SE.Existence of national Water & Sanitation M&E, & R System, and Year of Establishment:-There is no ‘’declared’’ M&E&R water and sanitation national system, on the other hand some institutions have management sub-systems for the data from the water sector such as the SYGREAU for the DGRE, the COPEAU for the ANPE, the SISOLS for the DGACTA and the aggregate monitoring system of the water sector under implementation at the BPEH, while other institutions have simple databases.

-The SINEAU: the national information system on water, which presents a dynamic portal, must bring together all the existing and the future sub systems. A workshop on the development project and the establishment of SINEAU just took place on 26/3/2013 in Tunis.
