For my sins I had never heard of these regs. But a company had done a survey at one of our sites and then issued an Enforcement notice for failure to comply with these reg with such things as an outside pipe not insulated and non drinking water signs on taps, I was under the belief that only the HSE/EHO could do that! Any advice would be appreciated guys and girls

Possibly the firm (you don't clarify who) is exceeding their remit here, the regulations refer to suppliers of water and keeping parasites harmful to human health out of their supplies, see below expanatory note from the regs themselves; These Regulations amend the Water Supply (Water Quality) Regulations 1989, which, in part, implement Council Directive 80/778/EEC (OJ No. L229, 30.8.80, p. 11) on the quality of water intended for human consumption. The amendments make specific provision intended to ensure that water supplied for human consumption is not contaminated with cryptosporidium, a parasite which can be detrimental to human health. The Regulations amend the 1989 Regulations to require water undertakers to carry out risk assessments to establish whether there is a significant risk from cryptosporidium oocysts in water supplied from their treatment works for human consumption (regulation 2(1)). Where it is established that there is such a risk the relevant water undertakers must use a process for treating the water to ensure that the average number of cryptosporidium oocysts per 10 litres of water is less than one. To verify compliance with this requirement water undertakers must ensure that the water leaving their treatment works is continuously sampled for cryptosporidium oocysts. Regulation 2(2) concerns criminal offences and regulation 2(3) requires the results of the monitoring to be placed on a publicly accessible record. Pete,

Mr F It sounds like you have been inspected under The water supply (water fittings) regulations 1999. As PeterL has quoted above the actual Regulations are now The water supply (water quality) regulations 2000 Made - 4th December 2000. Laid before Parliament - 8th December 2000. Coming into force in accordance with regulation 1(2) to (5). Amended by SI 2013/1387. I would suggest you contact your water supplier and ask them if they did carry out an inspection - they normally book an appointment. Could be you have had a plumbing company come in and said you need this work and that they can do it for a very reasonable fee
