STPs are technically unable to treat sewage as they cant remove nutrients or heavy metals. Most of them are dogged by maintenance. The By pass valves at pumping stations that are pumping untreated sewage to the STPs help them a lot, they just divert the untreated sewage into the public water rivers, streams, drains or lakes. The first step would be for the public to ask for locking up the By -pass valves. Then the STPs will become worse than the drains and the workers may just run away due to toxic levels of H2S gas.
