Monitoring potable water supplies
It is important for any industrial site to monitor their potable water supplies to
prevent pollution and to comply with the Water Industry Act 1991. The company should
focus upon the following areas:
- Gain site plans and find all water pipes, supply valves and stopcocks
relevant to the site
- Regularly inspect water pipes etc on site and ensure that any leaking taps
and pipes are repaired quickly
- Regulalry monitor the company's position with regards to any permit that may
be held to abstract water from boreholes and wells and that it is not being
breached
- Monitor water consumption patterns on site
- Undertake periodic sampling and analysis of water supplies on site. This is
most prevalent should steam-raising boilers be utilised, whereby chemicals to
limit corrosion or biocides should be added.
Some company's have more specific requirements imposed upon them to ensure that
their potable water is compliant with specific standards, coupled with the legislation
for industrial water quality given in British Standards or the British, US or European
Pharmacopoeia. Table n below gives this list
