IDS Part 7 – Water Supply, clause 7.4.4 –Contaminated sites references the UKWIR Guidance for the Selection of Water Supply Pipes to be used in Brownfield Sites document.
Part 3 of Guidance for the Selection of Water Supply Pipes to be used in Brownfield Sites (10/WM/03/21) [PDF, 1023 KB] provides guidance on selecting the appropriate pipe and joint material using data from site investigations and it is reproduced here with the permission of UK Water Industry Research Ltd.
Site investigation methodologies are detailed elsewhere in the UKWIR Guidance for the Selection of Water Supply Pipes to be used in Brownfield Sites document.
Since UKWIR published the Guidance in 2010, a supplementary guidance protocol has been produced by Water UK in collaboration with some UK water companies and the Home Builders Federation. This supplementary guidance can be downloaded from the Water UK web site, Contaminated Land Assessment Guidelines(external link).
When the IDS is next reviewed, these documents will be used to update Council’s guidance on treatment in brownfield sites.
