Water Quality - Our methods
We ensure vessels, fittings and equipment used in the supply and storage of water are of suitable materials conforming to guidelines set out in:
The Water Supply (Water Quality) Regulations 2016
DWI Guidance on the implementation of water supply (water quality) Regulations 2000 (as amended) in England 2012
DWI is the drinking water quality regulator for England and Wales.
Water Supply (Water Fittings) Regulations 1999
WRAS (Water Regulations Advisory Scheme) Guidelines
Cleaning and maintenance histories of our supply and storage vessels are fully documented in site logbooks.
We have strict in-house and external testing regimes in place to monitor supplied water, especially for harmful Legionella and E-Coli bacteria following guidelines set out in the following publications:
ACOP L8:2013 Legionnaires Disease. The control of Legionella bacteria in water systems. Approved code of Practice.
BS8551:2015 Provision and management of temporary water supplies to distribution networks (not including provisions for statutory) Code of Practice.
BS ISO 5667-21:2010 Water quality sampling Part 21: Guidance on sampling of drinking water distributed by tankers or means other than distribution pipes.
Daily, weekly and monthly in-house monitoring and testing regimes are in place with effectiveness of the programmes being monitored externally via samples being sent to UKAS (United Kingdom Accreditation Service) accredited laboratories for regular testing.
All results and findings are fully documented in site logbooks.
We are also able to provide portable laboratory testing services on site should the need arise.
