1 INTRODUCTION:
1.1 GENERAL
1.1.1 Water has a unique place in all the renewable resources of the planet. Water resources of
a country constitute one of its vital assets. Where there is water, there is life and where
water is scarce, life has to struggle. It is essential to sustain all forms of life, food
production, economic development, industrial growth and for general well being. It is
impossible to substitute water for most of its uses.
1.1.2 Water supply scenario in India has considerably improved during last two decades.
Planning commission report states that in India water is supplied to about 85% of the
urban and rural population but the challenge is in providing 24x 7 services. The main
issue of concern is the pollution of available surface water sources and depletion of
ground water table due to over exploitation. In India, the primary responsibility for
providing drinking water and sanitation facilities in the country rests with the State
Governments, and, more specifically, the local bodies in the urban areas.
1.1.3 Haldia city is fortunate to have water supply system for both industrial and domestic
supply. Haldia Development Authority (H.D.A.) the nodal agency and Statutory
Authority in charge of development of urban and industrial infrastructure in the region.
HDA is actively encouraging implementation and maintenance of infrastructure projects.
One of the key infrastructure requirements of the region is availability of reliable and
quality water supply. Haldia is an important industrial town with a residential
population of 200,762 as per 2011 census. Presence of several important industries such as
Haldia Petrochemicals Limited , Mitsubishi (MCCPTA) , Indian Oil Corporation Limited,
Indian Oil Petronas Limited, Tata Power, Tata Chemicals, Exide Industries , South Asian
Petrochem Limited, Reliance Industries, Electro-Steel Castings, Bharat Petroleum
Corporation Limited and others have made it a major industrial hub.
1.1.4 Haldia is also an important logistics hub, having a large riverside port. Haldia Dock
Complex, an important part of Kolkata Port System, has an annual throughput of 128,470
TEUs in Container Freight Service (CFS). Presence of several large industries, a large
DETAILED PROJECT REPORT
2
dock complex and a growing population has made Haldia an important hub in West
Bengal.
1.1.5 Haldia is in the process of being transformed into the most coveted industrial destination
in Eastern India. Hence, providing quality civic infrastructure and utility services has
emerged as a policy priority for Government of West Bengal. In order to achieve and
sustain this position, HDA has been working towards achieving of World class
infrastructure facilities in Haldia.
1.1.6 As part of its key obligation, HDA supplies treated water to industrial, commercial,
domestic & municipal consumers in and around Haldia town and Haldia Industrial Area.
For this purpose, it has set up a water treatment facility of 25 MGD capacity at Geonkhali
in 1992. In addition, there are fourteen (14) deep tube wells within the Haldia Planning
area to supplement potable water supply to the Booster Pumping station at
Chaitanyapur. The water treatment plant gets raw water from the Hooghli river through
an intake jetty, located close to the confluence of the rivers Rupnarayan and Hooghli.
This portion of the river is a tidal stretch, witnessing high and low tides twice in 24 hours
period. Turbidity reaches around 1600 NTU during monsoon. Because of proximity to
sea, the stretch suffers from high salinity level, which reaches more than 2000 ppm
during lean season of the year when there is no freshet in Hooghly and during high tides.
HDA mixes ground water drawn from 14 tube wells, at Chaitanyapur boosting station
before it is distributed to consumers. Also it has a 200 million gallon capacity of Pre-
Settling Tank, which receives raw water through three inlet channels. During low tide,
water quality is generally of acceptable level and salinity issue remains under control. So
by controlling intake flow of water, a proper mix can be achieved so that actual supply
does not get significantly affected by salinity problem. At distribution end, water supply
system consists of three boosting stations with semi underground reservoirs. The
boosting stations are located at Chaitanyapur, Basudevpur and at Hatiberia. Another
Pumping Station with reservoir is being constructed which is expected to be operational
in July, 2016. In 2005-06, augmentation of the old treatment facility was made by adding a
new 5 MGD filter to the existing 20 MGD capacity filters and by modification of the
existing clariflocculators with tube settlers at the periphery and Water Treatment facility
had been expanded to 25 MGD.

1.1.7 Construction and commissioning of new 25 MGD WTP over and above the existing 25
MGD had been operational since December, 2014. The new plant has separate intake
arrangement. It uses the existing raw water inlet channels (3 nos.) and settling tank of 200
million gallon capacity as a common facility. The new 25 MGD treatment plant with
semi-automated control system has been designed to supply water to Basudevpur
Boosting Pumping Station directly through a newly laid 900/1000 mm diameter D.I pipe
line through a bifurcation station, from where a separate pipe branches out and feeds
water to IOCL reservoir. HDA is now having at its disposal, combined water treatment
capacity of 52 MGD (50 MGD from water plants and 2 MGD from tube wells) for meeting
water demand of its valued consumers in Haldia Industrial Area.
1.1.8 In the year 2008, HDA entered into a Concession agreement with Haldia Water
Management Limited (HWML), a joint venture company of JUSCO and Ranhill Utilities,
Malaysia for construction of a new 25 MGD water treatment plant and the O&M of the
entire water supply network of Haldia for a period of 25 years. However for municipal
supply, HWML delivered bulk water to different zones of Haldia Municipality to its
reservoirs. The distribution network of Haldia Municipality is maintained by Haldia
Municipality. The agreement between HDA and HWML was in effect since November
2008 to March-2013. Since April, 2013 the Haldia Water Supply Project is being operated
and maintained by Haldia Development Authority.
2.0 HYDROGEOLOGY & TOPOGRAPHY
Haldia is a rapidly developing urban centre in southern part of Purba Medinipur district
of West Bengal. It is located at latitude 22º 03´ N and longitude 88º 06´ E. It is a major
riverine port and an industrial city of Eastern India. Haldia is located at the confluence of
River Haldi and River Hoogly and is 56 Nautical miles downstream of Kolkata. Haldia is
well connected by South-Eastern railways and by NH 41 and NH 6 with rest of India.
Haldia municipality covers a total area of 104.9 sq. km, comprising 26 wards. Haldia is
situated close to the confluence of River Hoogly and Haldi. River Hoogly, a distributary
of River Ganga, is the main drainage course of the area. Both Hoogly and Haldi are
estuarine in nature and experience tides. The rivers are fed mostly by upland discharge,
which is maximal during monsoon. Tides are diurnal with mean range during spring
being 4.90 m. Average velocity during tidal cycle is 1.75 m/sec. The soil in Haldia has a
DETAILED PROJECT REPORT
4
characteristic high water holding capacity. In rainy season, the water level rises to the
maximum of 1.50 m and during summer it falls to a depth of 5.5 m from the ground level.
Due to the high salinity of the Rivers Hoogly and Haldi in stretches near Haldia, they are
not suited for water supply. The required water for domestic and industrial water supply
is obtained from an upstream point at Geonkhali where Roopnarayan River meets River
Hoogly.
The general topography of Haldia town, which is spread over an area of 104.9 sq. km, is
relatively flatter having general gradient from North to South and South to West. The
river Hoogly meandering in a direction of South West to East flows by the Southern
boundary of the Haldia Municipality.
3.0 CLIMATE
Haldia has a moderate tropical climate with winter temperatures ranging from a low of
around 7 degrees Celsius to a high of 22 degrees Celsius. Summers can be very hot and
humid. Usual summer temperatures in May, the hottest month, range from a low of 24
degrees Celsius to high of around 39 degrees Celsius. Rainfall is heavy during monsoons,
and the rainy season spans between the months of June and September. The annual
rainfall is about 1600 mm.
4.0 PROJECT DESCRIPTION:

located at different places of Haldia Water Supply project. Another pumping station is
being constructed at Brajalalchak which is expected to be operational by July, 2016.
• Other associated infrastructure like electrical substations, water intake facility and settled
water pump house etc.
• Laying of pipeline from Chaitanyapur to Brajalalchak (Phase-II) has been constructed.
Construction of reservoir at Brajalalchak (Phase-II) and laying of distribution network
from Brajalalchak to Hatiberia (Phase-III) have been started and is expected to be added
with the Haldia Water Supply Project by July, 2016.
The raw water drawn from the river at Geonkhali is treated at the Water
Treatment Plants after which it is pumped to boosting station at Chaitanyapur. Then the
water is pumped at Chaitanyapur to Basudevpur from where the water is distributed to
different industries and domestic consumers. The water from series tube wells are mixed
with treated water at different pumping station to regulate the salt content of the water in
addition to other chemical treatments. Some dedicated water pipelines have been built
which supply water directly to different consumers. Regular operation and maintenance
is vital for ensuring proper water supply.
4.1 OLD 25 MGD WTP & WATER SUPPLY SYSTEM IN HALDIA
4.1.1 WATER INTAKE AND TREATMENT
The supply of water for the entire Haldia is sourced from the Hooghly River at
Geonkhali. Haldia Development Authority (H.D.A.) has an Old 25 MGD water treatment
plant at Geonkhali to cater to the demand of industries as well as domestic water in its
designated command area. Geonkhali is situated on the western bank of the river
Hooghly at the confluence of river Rupnarayan and river Hooghly. Raw Water from the
Hooghly river is collected through a 1000 mm suction mains (4 units) laid inside the river
bed with the help of intake -jetty. This is conveyed to pre-settling tanks of 200 Million
Gallons capacity by 3 nos. of intake channels. Water from pre-settling tanks is passed
through Filter Beds via Clariflocculators and Flash Mixer and finally through filter media.
It is then stored in Underground Clear Water Reservoirs

SCHEMATIC DIAGRAM OF WATER TREATMENT PROCESS AT NEW 25 MGD
WATER TREATMENT PLANT AT GEONKHALI
DETAILED PROJECT REPORT
22
4.2.2 NEW 25 MGD WATER TREATMENT PLANT PROCESS DESCRIPTIONS:
4.2.2.1 PRE-CHLORINATION:
Pre- Chlorination is the application of chlorine to water prior to any treatment process.
The point of application, dosages will be determined by the objectives viz. control of
biological growths in raw water conduits, promotion of improved coagulation,
prevention of mud ball and slime formation in filter beds, reduction of algal growth
in sedimentation tank and filter beds, reduction in colour, odour, taste. It also
minimizes the post chlorine dosages when dealt with heavily polluted water. In this
treatment plant Pre- Chlorination dosing is done at the inlet point of flush mixer.
4.2.2.2 COAGULATION AND FLOCCULATION:
Coagulation refers to destabilization produced by compression of electrical double layer
of the surrounding colloidal particles, while flocculation refers to destabilization by the
adsorption of the large organic polymers and subsequent formation of particle-polymer-
particle bridges. This distinction can have practical significance, since colloidal
aggregation involving destabilization by double layer compression occurs at constant
concentration of coagulant, regardless of the concentration of colloidal material. In
contrast, colloidal aggregation involving destabilization by the adsorption of large
polymers can involve a linear (stoichiometric) dependence of optimum coagulant dose on
the concentration of colloidal material.
The coagulation and flocculation process are accompanied with rapid mixing with
coagulant and subsequent slow mixing for flocculation. Slow and rapid mixing can be
done by mechanical means or by hydraulic means. Here slow mixing and rapid mixing
are done by hydraulic means. A series of baffle wall has been constructed in order to
achieve hydraulic mixing in the coagulation and flocculation chamber with closer spacing
in coagulation zone.
The coagulation and flocculation tank is specifically designed for water treatment mixing
application. It is to ensure complete dispersion of coagulants in the water by passing the
water through a series of baffle walls in the tank with a retention time of 30 minutes.
DETAILED PROJECT REPORT
23
Upon mixing of coagulant to water, a complete physic-chemical reaction occur leading to
the formation of stable floc which will be settled at subsequent sedimentation unit.
4.2.2.3 INCLINED PLATE SETTLER:
It is basically a rectangular sedimentation tank with a series of inclined plate within the
tank where the settle able flocs are settled at the bottom of plate settler. This unit helps
to reduce the amount of fine suspended and colloidal particles present in raw water.
The working principle of plate settler is described below:
• The liquid which contain floc formation particles are introduced between two
inclined plates. Every particle together with liquid will rise until it touches the
surface of the uppermost plate.
• Once the particle and liquid touches the plate surface liquid will rise to the surface
by sliding along the plate.
• Whereas the floc will fall back and touches the lower plate and will slide down
along the lower plate surface.
• Floc present in the liquid will not collide with floc / particular that is sliding down
along the lower plate.
As a result separation of floc / suspended / colloidal particles present in water takes
place. Finally the supernatant water, rising from bottom, will come out through a launder
from the plate settler and is sent to the Filtration Process. The settled sludge will be
transferred to the sludge treatment unit via timer control. The plates are usually set at an
angle between 45 to 60º above the horizontal to obtain self cleaning of sludge from plates.
Normal spacing between the plates is 50 mm.
4.2.2.4 DISSOLVED AIR FLOTATION AND FILTRATION SYSTEM:
Revo-Plus (RVP) is a unique combination of Dissolved Air Flotation (DAF) clarification
and dual media sand filtration in a self contained water treatment module that achieves
excellent water quality. This unit consists of 23 radial chambers in single RVF which
allows 22 chambers in operation and one unit in back washing mode. Thus continuous
production of filtered water and backwashing can be done simultaneously without any
interruption in segments within one RVP.
DETAILED PROJECT REPORT
24
Raw water enters the flocculation section of RVP. Directional inlet nozzles impart a
circular flow required mixing for optimum floc formation. Through the dissolved air
release mechanism located at the top of the inlet zone of RVP micro bubbles are
introduced which adhere to the floc and cause agglomerated particles to rise to the
surface of the treated water. A portion of the RVP effluent is recycled with pressurized
and semi saturated air. The recycled flow is mixed with unpressurised main stream just
before admission to the flotation tank, with the result that the air comes out of solution
in contact with particulate matter at the entrance of the tank. A spiral scoop then removes
the floated and concentrated accumulation of floc via central pipe. RVP has 23 isolated
cells, hence it is possible to back wash one cell at a time without interfering with
filtered water production from the remaining cells. To accomplish this, a backwash hood
is mounted on a rotating carriage, which is supported and driven by wheels at the top of
the RVP tank. The carriage is programmed to either rotate pass a given cell, or to stop,
lower the backwash hood, and backwash a particular cell. The frequency and the
duration of cell backwash is pre set by control panel, which can be adjusted to suit
process condition. The carriage supports the sludge scoop and the electrical rotary slip
rings which distribute electrical power and control function for the carriage drive
motor and scoop drive motor. A rotary air joint supplies air to raise and lower the
backwash hood. All of these functions are operated by the programmable controller.
4.2.2.5 POST CHLORINATION:
Post Chlorination is the application of chlorine to treated water before it enters into
distribution system to maintain the required amount of free chlorine i.e. ≥ 0.5 ppm. The
objective of post chlorination is to destroy the micro-organisms present in water.
Sufficient chlorine is added to maintain free residual chlorine of ≥ 0.5 ppm as specified in
CPHEEO Manual. Chlorine residual is required to prevent re growth of microorganism /
future contamination in distribution system. Liquid chlorine is used for this purpose.
Chlorinator has been provided for proper dosing of chlorine in to the system. A chlorine
analyzer has been installed to determine the free residual chlorine in the system.

8.0 DETAILS OF EXISTING CONSUMERS OF HALDIA WATER SUPPLY PROJECT:
Haldia Development Authority supplies water to industrial, commercial, municipal and
domestic consumers. Water supply to Haldia Municipality is made from several intake
points to their reservoirs. Domestic supply includes bulk supply to housing complexes or
large residential complexes.
8.1.1 LIST OF EXISTING INDUSTRIAL CONSUMERS:
Haldia being an industrial region, industrial water supply to existing and upcoming
industrial units is of paramount importance to HDA. The major industrial consumers of
Haldia Development Authority are MCCPTA, HPL, IOCL, Tata Power etc. They consume
about 86% of total industrial water consumption of Haldia Water Supply Project. The raw
water is drawn from river Hooghly and is allowed to settle in big settled water ponds. The
settled water is then pumped to the treatment plants. Treatment method followed in the
water treatment plant consists of Coagulation, flocculation, sedimentation, filtration and
disinfection. The treated water is stored in an underground reservoir having capacity of 2300
CUM and pumped through 1100 mm and 700 mm dia pipe to the booster pumping station at
Chaitanyapur. A dedicated booster pumping station with three centrifugal pumps has been
constructed at Chaitanyapur to supply water to HPL through a dedicated 500 mm dia
pipeline. From Chaitanyapur booster pumping station, water is pumped to the Basudevpur
Booster pumping Station. MCCPTA is fed by a dedicated line from Basudevpur Booster
Pumping Station through a separate set of pumps. All other industries are directly fed from
Basudevpur Underground Reservoir (UGR). IOCL , Haldia Refinery receives water through
a dedicated 900 mm dia D.I pipeline from Chaitanyapur. From Basudevpur, MCCPTA is
served using five vertical pumps of which two were installed in 1988 and another set of three
installed during 2009. The rest of the industries are served from Basudevpur pumping station
using ‘Primary Grid’ supply network. ‘Primary Grid’ is connected to six pumps located at
Basudevpur pumping station drawing water from the existing 22.7 ML (million litres)
reservoir.

10.0 RAW WATER QUALITY:
The present water supply system primarily uses raw water of river Hooghly drawn through
Intake jetties near Geonkhali Water Treatment Plant.
Raw water collected through intake jetty at Geonkhali has two key quality issues: high turbidity
and high salinity. Out of that, the turbidity issue can be addressed relatively easily through
primary sedimentation and clariflocculation system in the WTPs.
The water to be handled may vary both in quality and quantity. The water quality of river
Hooghly varies from season to season. The turbidity level in rainy season is as high as 1600 NTU
to as low as below 100 NTU in winter. The degree of treatment required may vary seasonally,
monthly and even hourly. Raw water quality of river Hooghly, in terms of turbidity, pH and
Total Alkalinity is given below.

10.1 Salinity in Hooghly near Geonkhali
Geonkhali, the location of the WTPs is in a stretch of Hooghly which experiences a semi-diurnal
tidal cycle. Mixing of saline sea water of the Bay of Bengal with the freshet of Hooghly makes it a
source which is not always a fresh water source. The level of salinity is highest during the dry
period of no or insignificant freshet through Hooghly. Salinity decreases with increase in freshet
during Monsoon and Post Monsoon seasons. Again, level of salinity varies during the semi-
diurnal tidal flows, two high tides in a day giving rise to high levels of salinity while salinity
levels are significantly low during two low tides, in general. The following Table describes
quality of raw water generally available and corresponding duration in a day during different
seasons in a year:

Data were collected three to six times a day, as required for establishment of a daily trend in salinity. During March and June, samples are generally within the WHO guidelines (cause for Rejection) of
potable water that is less than 1000 ppm during low tides. Strict monitoring, however, is required
during April to draw water during the low tides, only for the periods when chloride levels are
within 500-700 ppm levels. Salinity issue is being addressed by HDA by strict monitoring of

salinity levels during low tides, prudent operation of pumps and mixing treated water with
ground water from the existing bore wells near Chaitanyapur Pumping Stations.
10.2 Raw Water Pumping Capacity
The Present System has 4 raw water pumps (@ 4500 cum / hour capacity) of the old plant and 4
raw water pumps (@ 5100 cum / hour capacity) for the new plant. Though there are separate
raw water pump houses, raw water reservoir is common. Therefore, raw water pumps could be
run in tandem to supply raw water to both the plants from a common reserve.
Considering no overloading for the pumps, the existing capacity of raw water pumping comes to
28800 cum per hour (3X4500+3X5100). For 7 hours’ pumping, total raw water drawn is about
201600 cum i,e 44.4 MGD. (Loss in treatment, transmission could be met by minor overloading of
raw water pumps for supply of water upto 51 MGD). The suction pipes having 1000mm
diameter, shall be subject to a suction velocity which is well within the permissible limit of
velocity in suction pipes in accordance with the Manual.
