Electrical Circle, Shillong (v) Williamnagar Circle (vi) Western Circle, Nongstoin (vii) Ri Bhoi circle, Nongpoh. There are 21 Divisions in all throughout the state, having at least one Division in each District.
• RURAL WATER SUPPLY PROGRAM
PHED takes up Rural Water Supply Projects for providing drinking water supply facilities in Rural Areas of the state. Providing safe drinking water supply is included under 20 point program & the targets are fixed for coverage of habitations. Projects are taken up for Not covered (NC), Partially Covered (PC) & Iron affected habitations as per 1994 survey as well as for Renovation /Reconstruction of schemes which have been implemented more than 15 years back, for improvement of existing facilities as well as sustainability of drinking water sources.
Rural Water Supply Schemes are taken up under Bharat Nirman Programme, which was launched during 2005-06 with the goal to cover all the not covered, partially covered & quality affected habitations by 2008-09.
Schemes are taken up both under State & Central Plan namely:-
- Central Sector Accelerated rural water Supply Program (ARWSP)
- State Sector Rural Water Supply
- ACCELERATED RURAL WATER SUPPLY PROGRAM (ARWSP)
Under ARWSP projects are taken up for Not covered (NC), Partially Covered (PC) & Iron affected habitations .Water Supply to Schools & Anganwadi Centres is also taken up under ARWSP with 50:50 sharing by Central & State Govt. Sustainability of sources/Schemes are also taken up under ARWSP. Schemes for removal of excess Iron is taken up under Submission Programme of Govt. of India with funding pattern of 75:25 by Central & State Govt. Mostly IRPs are constructed for removal of excess Iron from drinking water to make it potable. In some cases, alternative sources are tapped for providing safe water supply. For the projects sanctioned after 1.4.99, central share is met from overall ARWSP allocation. But from 2006-07, separate fund is allocated for Submission Projects
Power has been delegated to the State for sanctioning schemes under ARWSP. These schemes are sanctioned by State Water Supply & Sanitation Mission (SWSM) headed by the Chief Secretary from 2003-04 onwards. Earlier, schemes were used to be sanctioned by State Level Advisory Board (SLAB) headed by the Chief Secretary, after clearance of the proposals by Scientific Source Finding Committee (SFC) at the State Level headed by the Commissioner & Secretary (PHE) with the Officer in charge of Central Ground water Board (CGWB) as Member Secretary.
Allocation for ARWSP varies from year to year.. For 2007-08, Govt. of India allocated Rs.4446.00 Lakhs & released full amount in four installments. Another Rs. 1083.00 Lakhs was released under ARWSP on 31.3.08. Thus available fund under ARWSP was thus Rs.6791.17 Lakhs for 2007-08. As against this, the expenditure was as below:-
ARWSP Rs. 5661.16 Lakhs
Allocation under ARWSP during 2008-09 is Rs. 5779.00 Lakhs, which also includes allocation for water quality improvement program. Govt. of India released Ist installment amounting to Rs. 2890.00 Lakhs in two instalments. Another Rs. 1083.00 Lakhs, which was released under ARWSP on 31.3.08 & unspent balance of Rs. 47.01 Lakhs from 2007-08 is also available. Actual availability of fund under ARWSP as of now is Rs. 4020.01 Lakhs. Committed liability for schemes under ARWSP as on 1.4.08 is about Rs. 222.00 Crore. Funding pattern of ARWSP sachemes has been changed to 90:10 from 2008-09 onwards ( earlier it was 50:50 by Central & State govt. )
- STATE SECTOR RURAL WATER SUPPLY PROGRAM :-
The projects for NC, PC, Iron affected habitations are also required to be taken up under State Sector Rural Water Supply Program (PMGY) also, as providing safe drinking water supply is included under 20 point program & the targets are fixed for coverage of habitations. More over, since projects can be taken up under ARWSP only for restricted parameter as above & the availability of fund under ARWSP is also limited, the projects for Renovation/Improvement of existing schemes are required to be taken up under State Sector only. Moreover, to avail the benefit under ARWSP, matching State share is required to be provided by the State Govt.
The Availability of fund under State plan varies from year to year. The availability during 2007-08 was Rs. 42.74 Crore. For 2008-09, the allocation is tentatively fixed at Rs.45.00 Crore.
TYPES OF RURAL WATER SUPPLY SCHEMES
The Types of Water Supply Schemes Implemented by the dept. are:
The schemes are implemented giving preference in the above-mentioned order to make it economically viable.
- Ring Well
- Spring Tapped Chamber
- Deep Tube Well (DTW) with India marked-II Hand Pump
- D.T.W. with Power Pump
- Gravity Feed Water Supply Scheme
- Pumping Schemes with Diesel or Electricity from river or stream source.
The sanctioned projects are priority projects and hence executions of all the sanctioned projects were taken up immediately after sanction. However, with the limited State Plan Resources, it is not possible to provide sufficient fund for completion of all the schemes.
• 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:-
- State Plan: - Major Schemes under implementation in Urban sector are:-
Modification of pumping machineries & replacement of treatment units of GSWSS”:- The estimate for the purpose was administratively approved for an amount of Rs. 1866.42 Lakhs during 2004-05. The Scheme was formulated to take care of the following:-
- Replacement of pumps of second stage pumping system
- Install VVVF (Variable Voltage variable frequency) drives which could maintain stable output voltage & frequency thereby enabling controlling generated flow of water during the process of pumping. High variation in frequency is harmful to the machineries & equipments. This adversely affected the efficiency of the pumping system. Due to variation in frequency, the system was unable to deliver the water to the Treatment Plant & accordingly three stage pumping was introduced in GSWSS. With the installation of the system, the third stage pumping system will be completely do away with , reducing the energy cost and operation & maintenance cost for the scheme. However, this effect will only be felt in the long run.
- The proposal also has provision for modernization of power system, which comprises construction of a 33/6.6 KV sub station, replacement of 2 nos. 33/6.6 KV, 2.5 MVa transformers (which has been subjected to heavy weathering), replacement of current carrying of cables to cater power to the increased capacity of motors.
- The estimate has also provision for replacement of existing manually operated valves with sophisticated pneumatic valve with pneumatic cylinder & 3 points electrical signal, replacement of air compressor & different drives installed at 7.5 MGD treatment Plant.
There is a provision for complete automation with visualization system for operation of different units of the plants in the. This would not only help achieving correct operation of machineries but also ensure providing timely information on the need for timely maintenance of these machineries.
Replacement of pumping machineries of second stage pumping system has since been completed &water supply position in capital city has improved substantially.
“Replacement of Pumping Machineries of Ist Stage Pumping Stations of GSWSS” was also completed during 2006-07.
The availability under Urban Sector (State Plan) varies from year to year. For the year2007-08 actual availability was Rs. 350.00 Lakhs. For 2008-09, the outlay has been tentatively fixed at Rs.450.00 Lakhs.The State Share for Centrally Sponsored Schemes is also provided from Urban sector allocation.
- Non Lapsable Central Pool of Resources(NLCPR):- Four 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. Total Expdt. up to March 08 is Rs. 2069.27 Lakhs (Central Rs. 1969.27 Lakhs, State Rs. 100.00 Lakhs). Overall progress is 85%.The scheme is likely to be completed by March 2009.
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. Total Expdt. up to March 08 is Rs. 915.34 Lakhs. Overall progress is 46.72%. Efforts are being made to complete the scheme by 31.3.10.
Mairang WSS:- DONER has included Mairang WSS for funding under NLCPR at an estimated cost of Rs. 806.56 Lakhs.. The works for the project started during 2006-07. DONER has so far released Rs.461.53 Lakhs. Total Expdt. up to March 08 is Rs. 379.43 Lakhs. Overall progress is 50%. Efforts are being made to complete the scheme by 31.3.10.
The Scheme was technically cleared by the Ministry of Urban Development & Poverty Alleviation, CPHEEO, New Delhi vide No.Q-12021/1/2006-CPHEEO dated 10.11.2006 for an amount of Rs.1746.725lakhs. The scheme has been included by DONER (Department for Development of North Eastern Region) for funding under Non Lapsable Central Pool of Resources (NLCPR) during 2006-2007 vide.F.No.DNER/NLP/MEG/97/2006. Dated 26.03.2007 The Scheme was administratively approved by State Govt. vide No.PHE.112/2005/39 dated 31.03.2007. DONER has so far released Rs.550.21lakh for this schemes vide letter F.No.DNR/NLP/MEG/97//2006 dated 26.03.2007Total Expdt. up to March 08 is Rs. 550.21 Lakhs. Overall progress is 34.58%. Another Rs. 600.00 Lakhs was released during 2008-09.
- Centrally sponsored Accelerated Urban Water Supply Program (AUWSP):- 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. All the works were completed during 2007-08. At present testing is in progress & would be commissioned by December 2008.
CONCLUSION: - It is the endeavor of the Dept. to complete all the schemes within the scheduled time. However due to paucity of fund and other reasons like theft, dispute on land/source, inter village rivalry, non completion of work in time, the implementation of the schemes are some times delayed. The system of reviewing & monitoring the implementation of schemes has been strengthened. It will be the earnest effort of the PHED to provide adequate safe water supply from the scheme to the intended population within scheduled time of completion.
