wrightyson – the EA would be concerned, report it and STW’s response to them. Or just send the evidence of zero response from STW to OFWAT directly
Ea not bothered either as it was on private land.
It’s not in the EA’s remit to control discharges to foul sewer, only if it’s being discharged to surface water or ground water. So it’s not a case of not being bothered, they simply don’t deal with that sort of thing.
It’s a matter between the people discharging and the water company only. It might be the case that the local STW (sewage treatment works) is not under stress from that extra discharge (either from type or quantity) so dealing with it is way down their lists of priorities.
