ON GOING SCHEMES UNDER URBAN YEAR 2005-06
URBAN WATER SUPPLY PROGRAMME
All the urban centres of the State have been provided with water
supply. However, to augment the supply, schemes are taken up under the
programme. Urban Water Supply Schemes are funded under three programmes:-
1. State Plan:- Major Schemes under implementation in Urban sector are:-
Greater Shillong Water Supply Scheme (GSWSS):
The Schemes was taken up for implementation in two stages.
The Phase-I of the Scheme was completed in mid eighties .For Phase-II, all the
major works except testing of some of the distribution lines in Lachumiere
& Sectt. Hill, Nongthymmai area, Polo area & Malki Area, commissioning
of 3.8 MGD treatment Plants & some other minor works are completed. The
scheme is likely to be completed by 31.3.06 in all respect. The Supply position
will increase in the capital city with the completion of the Scheme &
replacement of pumping machineries of Ist Stage & 2nd stage Pumping
Machineries. The project was taken up for execution with Limited State Plan
for one time LIC loan of Rs.250.00 Lakhs received during 1982-83, due to which
the desired progress could not be made in the past years. However in the year
1998-99, the scheme was included for financing under Non Lapsable Central Pool
of Resources (NLCPR) & an amount of Rs.3579.00 Lakhs was received under
Central Pool for execution of the Scheme(mainly Dam) . The remaining fund for
implementation of the project was provided from State plan resources.
“Replacement of Pumping Machineries of Ist Stage Pumping
Machineries of GSWSS”:- These first stage pumps & motors (total 6 nos.)
were procured originally in the year 1981 & put into operation in the year
1986 after completion of infrastructure of the Phase-I of the scheme. The
designed life of pumping machineries is 15 years. The pumps procured for GSWSS
has been in operation for about 20 years & has outlived the designed life.
Due to continuous running for 24 hours a day since 1986, 2 nos. of these first
stage pumps & motors have become unserviceable as a result of wear and
tear. Further, efficiency of the remaining four nos. of pumps & motors has
come down considerably and there is frequent breakdown of these first stage
pumps & motors. Accordingly the proposal was taken up. The work has been
entrusted to M/S Voltas.
The availability under Urban Sector (State Plan) varies from
year to year. For the year2005-06 actual availability is Rs. 60.00 Lakhs. There
is also LIC loan component of Rs. 200.00 Lakhs during the current year, which
is not likely to be made available. In addition, there is a provision of
Rs.570.00 Lakhs for the modification of pumping machineries of GSWSS. The State
Share for Centrally Sponsored Schemes is also provided from Urban sector
Non Lapsable Central Pool of Resources(NLCPR)
Two Schemes are presently being funded by DONER under NLCPR namely:-
Tura Phase-III WSS: - Tura Phase-I WSS was taken up
during 1968 as a gravity feed scheme to cover the ultimate population of
50,000. The scheme was completed in 1972 at a total cost of Rs.79.35 Lakhs. The
discharge of the “Rongkhon” river, source of Tura Phase-I WSS started reducing
considerably reaching an all time low during March 1978, resulting in acute
water crisis in Tura town. This compelled the dept. to go in for Tura Phase-II
WSS by pumping water from “Ganol” river to the existing Treatment Plant of Tura
Phase-I WSS. The scheme was taken up in 1980 at a total cost of Rs.2.28 crores.
With the increase in population, many new localities also came up in Tura,
which were without water supply. Hence, the Phase-II estimate was revised to
accommodate all hitherto uncovered areas of Tura and the revised estimate was
sanctioned in 1984 at a total cost of Rs.4.82 crore. The scheme was designed
for an ultimate population of 87827 with 1997 as the ultimate year. The
population of Tura town is fast increasing and 37 new localities have come up
in and around new Tura area, which are without any water supply. The present
population of Tura town as per the certificate of the DC, Tura is 90,501.Tura
Phase-III WSS is proposed as a separate gravity scheme to cover newly developed
localities. Out of the total population of 90,501people, 32225 people of the
newly grown area will be covered by the proposed scheme. The balance population
of 58276 people will be continued to be fed from the existing Tura Phase-II
WSS. Tura Phase-III water supply scheme was sanctioned by Govt. of India,
Ministry of Urban Development on 7.10.2002 for an amount of Rs.2160.24 Lakhs.
This project is funded under NLCPR. The work has started from 2003-04 & is
in good progress.
Jowai WSS: - The original Phase-I Water Supply Scheme for
Jowai town was started in 1974 & was commissioned in 1980 at a cost of
Rs.95.00 Lakhs. The scheme envisaged pumping of water from Myntdu River, which
was flowing by the side of the town. The ultimate designed population of the
scheme was 39,000 to attain by 2004. The existing treatment plant has a
capacity of 1.50 MGD.
River Myntdu has become highly polluted during the past years as
numbers of stone quarries have come up on the upstream side of the river.
Further, since Myntdu River surrounds the Jowai town, all the sewage &
sullage effluents of the town are discharged in the river. There is a
persistent demand for making alternative arrangement for supplying water to
Jowai town. Apart from this, there are substantial water losses from the laid
distribution system as structures /roads have come up on most length of the
pipes, especially in congested areas due to rapid growth of town. Moreover,
most length of pipes has outlived their lives.
Further the design period of the existing scheme has reached by
2004 & hence there is the necessity to take up new scheme to meet the water
demand of the entire population.
To overcome the above mentioned problem an alternative river
pumping scheme from ”Umngot” river was sanctioned by Govt. of India, Ministry
of Urban Development on 25.10.2002 for an amount of Rs.1541.13 Lakhs. The
project is being funded under NLCPR. The works are likely to pick up from
Centrally sponsored Accelerated Urban Water Supply Program
The projects are taken up under the programme for towns having population less
than 20,000 as per 1991 Census. The sharing pattern of the project under the
programme is 50:50 basis by Central & State Govt. Projects for two towns
(William Nagar & Baghmara) have so far been taken up under the program. Of
this, the project for William nagar town has been commissioned during 2004-05.
The scheme for Willimnagar town envisages tapping the river
“Chibok” by gravity, which is flowing 12KM away from the existing Treatment
Plant site with provision to treat raw water at the existing Treatment Plant.
The treated water then pumped to different Zonal reservoirs for eventual
distribution by gravity.
Earlier, water was used to be pumped from Simsang river with the
help of submersible pumps. There were frequent disruptions of water supply in
the rainy season due to increase in discharge & sediments. With the
commissioning of the gravity feed scheme, this
problem minimized to a great extent.
The scheme for Baghmara town was designed as a River Pumping
Scheme from Simsang river with provision for a Jack Well, installation of V. T.
Pump, laying of 200mm dia M.S. Pumping main, construction of simplified water
Treatment Plant, construction of Zonal reservoirs along with distribution
networks to different zones and other ancillary work. The work is progressing
satisfactorily and expected completion of the scheme by March 2006.
Improvement of Municipal Sources:-
A scheme for improving the quality of water of municipal sources
supplying water in parts of Shillong & integrating these sources with
GSWSS, so that mixing of treated water with untreated water is avoided
&uniform quality of water is maintained in water supplied to all the people
of Shillong, is under implementation .The Project is funded by Central Govt.
with 90:10 funding by Central & Stare Govt.
