I live in a complex housing 380 flats. We have WTP treating raw well/ bore water. We carryout prescribed Back wash of filters- & this back wash water is red brown in colour indicating heavy amount of iron that had been filtered. This water is fed into a defunct well close to other wells from which we draw water.
I have some queries regarding this practice:
1. I am of the opinion that this should not be done as it is going to contaminate the water table with more iron concentration. Is my view correct?
2. Is there any harm to divert this back wash water into the raw sewage collection sump? We have STP also,& which processes the sewage to treated water.
3. Will the back wash water from WTP rich in iron if let into the raw sewage collection sump affect the functioning of the STP?
Kindly clarify on the above aspects.
