CSE recommends BOD as suitable parameter for water quality, wants equipment approval simplified
Biological Oxygen Demand (BOD) is a satisfactory parameter to measure water quality. However, the process of measurement should be improved and speeded up. Two ways of doing this are using a bio-sensor based system or a spectrophotometer, that give results within minutes and are nearly as accurate as laboratory-based monitoring. That said, conventional laboratory testing must also be made more robust with clear protocols for sampling, transport and testing.
Maintenance and Monitoring
Once you have installed a RWH system it is a good idea to also set a system for monitoring. How much water you are catching How much of this you are using How much you are recharging This will help you to provide concrete evidence of the impact of rainwater harvesting If the data is positive it will help to catalyse other people to follow in your footsteps.
Monitoring Reports August 2008
The first monitoring was undertaken on August 22, 2008. When the farmers group visited the CETP for sampling, they observed bypass of untreated effluents and the district administration and the pollution control board was informed of the same.
