Home / Water Quality Monitoring
SPCB Sikkim has been implementing the National Water Quality Monitoring Programme (NWMP) to consistently monitor the water quality in a systematic
manner to know the nature and extent of water quality degradations and the existing quality of water in the water bodies.
The national programme is also termed as Monitoring of Indian National Aquatic Resources (MINARS). Under the MINARS programme the State Pollution Control Board Sikkim
collects water samples from River Teesta and its tributaries and also from lakes from 25 identiifed sites. This program is funded by Central Pollution Control Board.
The major objectives of water quality monitoring are:

SPCB Sikkim has been continuously monitoring the industrial activities by ensuring continuous operation of Effluent Treatment Plant (ETP).
Further, SPCB Sikkim has made Zero Liquid Discharge (ZLD) mandatory so that the treated water meeting the prescribed standard is recycled and reused for gardening, flushing, cleaning and cooling purposes.
