The most recent leakage data water companies reported to the Environment Agency is for the financial year ending March 2021. The reported data is at water company level. Coventry is served by Severn Trent Water, which also provides water services to wider parts of the West Midlands. South Staffordshire water also supplies water to customers in parts of the West Midlands.

Reported leakage for Severn Trent Water for the last three years in millions of litres per day (Ml/d) is as follows:

  • 2018-19, 417.8 ml/d;
  • 2019-20, 398.8 ml/d;
  • 2020-21, 410.2 ml/d.

Reported leakage for South Staffordshire Water for the last three years in millions of litres per day (Ml/d) is as follows:

  • 2018-19, 70.5 Ml/d;
  • 2019-20, 68.9 Ml/d;
  • 2020-21, 65.5 Ml/d.

Reported leakage for England for the last three years in millions of litres per day (ml/d) is as follows:

  • 2018-19, 2969.8 ml/d;
  • 2019-20, 2772.6 ml/d;
  • 2020-21, 2829.1 ml/d.

The Government had set clear expectations that water companies should cut their leakage by 50% by 2050, based on 2018 levels.
