Every day, right across the region, we're flushing the loo, emptying the sink, using the washing machine and putting the dishwasher on and all that used water has to go somewhere. We collect 1,271 million litres of it ( now that's a lot), every day, then take it along 72,000 kilometres of pipes and sewers to our 580 wastewater treatment works, before returning it to the rivers and sea. It's a dirty job but somebody's got to do it - and we're more than happy to, after all number twos are our number one priority!
