The Discover Water website publishes up to date records on leakage. Details can be found here: discoverwater.co.uk/leaking-pipes.

Severn Trent and South Staffordshire cover Coventry and the West Midlands. A map of the area that each water company in England covers can be found here: www.ofwat.gov.uk/contact-companies.

Below is the data as reported by the water companies in their annual returns on water resources management plans. We have included the total leakage for Severn Trent Water and South Staffordshire Water which are the water companies in the area. The total leakage is in megalitres per day. One megalitre is 1,000,000 litres.
