SECTOR (B) URBAN
WATER SUPPLY
In Assam the PHE department is working
to supply safe drinking water to the rural
communities and fulfil the demand. There
is also a Urban Water Supply and Sewerage
Board to look after the urban water supply.
In BTC area, PHE department is working both
in the rural as well as in urban areas also.
Since inception of BTC, the PHED has been
working on 2 (two) urban water supply schemes
at Kokrajhar Town Water Supply Scheme at
Kokrajhar and Bijni Town Water Supply Scheme
at Bijni.
Kokrajhar Water
Supply Scheme:- Kokrajhar water
supply scheme was administratively approved
during September, 2005 and foundation stone
was laid on 20th December, 2005. The scheme
has been taken up under BTC special package
for an amount of Rs. 2357.00 lakhs. The
project will cover an area of approx 7 Sq.
Km. including 10 (Ten) Municipal Wards of
Kokrajhar and adjoining areas of Kokrajhar
Town. At present 60,000 population will
be covered but has been designed for 1,20,000
population at the final stage.
Due to non existence of Urban Water Supply
and Sewarage Board in Kokrajhar the execution
part of the project is entrusted to Rural
PHE Department under the proper guidance
of BTC authority. The execution of the project
is in full swing and likely to be completed
during the year 2007.
The entire Kokrajhar Water Supply Scheme
is divided into two part, Northern Zone
and Southern Zone of the railway track.
The Southern Zone (Zone-I) with two over
head reservoir plant with a capacity of
750 CUM (7,50,000 Litres) per ESR (*ESR=
Elevated Service Reservoir). The project
is established at the back- side of Govt.
H.S. & MP School and nearest to the
new Magistrate Colony to cover up the entire
population of the southern part of the Kokrajhar
town.
The Northern Zone (Zone-II) is established
at J.D. Road near Forest Depot Office with
the same capacity of 750 CUM (7,50,000 Litres)
per ESR (i.e. 2 ESR Northern side) and one
treatment plant to cover the entire household
benificiaries of the northern part.
The Kokrajhar Water Supply Scheme is a dream
project for BTC and Hon'ble Executive Member,
PHE alongwith the official team of PHE has
taken earnest effort in successful implementation
of the project in addition to monitoring
the project works at site. The project is
scheduled to be completed within 2007.
