The suggestion that Thames Water is considering shipping sewage outside south east England (NCE 20 March) is incorrect.
It is true that we are concerned about sustainability problems caused by development pressures in the area, not just in terms of water resources but also the capacity of local rivers to carry treated effluent. We are facing ever tighter limits on the quality of discharges from our sewage treatment works, despite increasing housing pressures.
However, while we have looked at the limited possibilities of taking waste water to other local works, we have never contemplated exporting it outside our region.
