Water Supply Pipe Site Assessment Reports (SAR)
Preliminary Site Assessment Reports (PSAR) and Site Assessment Reports (SAR) are undertaken to determine the water supply pipe material requirements in accordance with the recommendations provided with the UKWIR document "Guidance for the Selection of Water Supply Pipes to be used in Brownfield Sites".
Similar to a Phase 1 Contamination Risk Assessment, the Preliminary Site Assessment Report (PSAR) entails the consultation of historical, geological and environmental data and a walkover survey to produce a ‘conceptual site model’ (CSM). The CSM is used to identify if there are any likely sources of contamination that might be harmful to water supply pipes.
If a potential source of contamination is identified, laboratory testing is undertaken as part of a Site Assessment Report (SAR) to identify whether or not upgraded water supply pipes are required.
