Teddington Direct River Abstraction project

Thames Water wants to build a series of pipes upstream of Teddington Lock as part of its drought protection strategy.
One will take water from the Thames to reservoirs in the Lea Valley, in East London.
A second will add treated wastewater from Mogden Sewage Works, to top up the river level, just upstream of Teddington Lock.
London Waterkeeper wants to know the answers to three questions, if the answer to them is yes, we will oppose the project when the planning application is submitted next year.
1) Will there be an increase in faecal bacteria levels in the area where people swim?
2) Will there be an increase in nutrient levels in the Thames as a result of treated wastewater being added from Mogden Sewage Works?
3) In periods of drought, the water level falls in the Thames. Will abstraction volumes be reduced when the river is low?
We need people to hold Thames Water to account and give detailed answers to these questions. We need to know that Thames Water has accurate data and modelling on whether water quality will fall.
We need to know if the extraction pipe will be able to function when water levels are low, if not it will be a costly mistake. Thames Water built a desalination plant in East London for £250m, but it isn’t working, because salt levels change as the tide ebbs and flows.
