ON GOING SCHEMES UNDER URBAN YEAR 2005-06

URBAN WATER SUPPLY PROGRAMME

1. State Plan:- Major Schemes under implementation in Urban sector are:-

“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 allocation.

2. 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 2005-06 onwards.

3. Centrally sponsored Accelerated Urban Water Supply Program (AUWSP):

   Guidelines for Accelerated Urban Water Supply Programme

   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.
