Implementation of PWSS are going on under Master Plan for Arsenic Mitigation throughout West Bengal. As on date there are some left out water quality affected habitations. As per the guidelines of MoDWS these left out quality affected habitations are to be covered through Community Water Purification Plants (CPPs) on priority basis. To comply with the directions, an attempt has been made for installation of Standalone CPPs in severely arsenic affected district of West Bengal. The CPPs which have been proposed are solar power operated and Arsenic removal media that has been used is developed by IIT, Madras. The system draws energy from solar power which is a sustainable & clean source of energy and which reduces the operation cost in the long run. These CPPs are being installed and commissioned by PHE Department, Government of West Bengal. In order to ensure its sustainability the O&M of these CPPs has to be taken care of by the beneficiaries. Otherwise the objective of this initiative cannot be fulfilled.
To operate and maintain the plant successfully by the user group following are the key targets that have to be achieved:
- Formation of Village Water & Sanitation Committee (VWSC) / User Group
- Training for operation of the Plant to be imparted to the nominated person of VWSC /User Group during first year of departmental Operation & Maintenance of the plant.
- Handing Over of the Plant to the VWSC / User Group after one year of departmental O & M.
- Sustainable O&M of the plant by the VWSC / User Group for atleast 10 years.
These are the basic goals that have to be achieved. To achieve these goals involvement of local Administration is very much essential along with capacity building of the VWSC/ user groups which are directly responsible for the O&M of these systems.
In the subsequent pages of this booklet, details about the plant and its O&M have been included. It has also been shown analytically, how the plant can be run by VWSC / User group in an economically self-sustained way. Two nos. case studies was also been done by WSSO, PHED to get a realistic idea about O&M of community water treatment plants in two different districts of the state. The community contribution considered here is at par with prevailing rate of community contribution where such plant exists.
So it is an holistic approach to supply safe drinking water to the quality affected habitations with no access to safe water supply in the State.
