What Standards and Responsibilities Apply to Water Pressure?
South West Water has a statutory requirement to supply water by gravity continuously for domestic purposes at a pressure that will "reach the top of the top-most storey of every building" (Water Industry Act 1991 Section 65).
We also have service standards agreed with Ofwat that require a minimum supply pressure of 7 metres head, measured at the point where our communication pipe joins your supply pipe. We do seek to improve on this minimum standard and normally expect to provide a minimum pressure of at least 10 metres head at the end of our communication pipes.
