Water Treatment and Purification

Water Hygiene Service Contracts

Water Hygiene

Opal offer bespoke water hygiene contracts for a range of services, including testing, temperature monitoring, flushing and equipment servicing. Our engineers are proactive and thorough, providing the best possible support.


When legionella bacteria grow and spread in water systems that create an aerosol – like showers, cooling towers, hot tubs and other plumbing systems – they become a health concern. Opal provide risk assessments, training, testing and treatment for legionella.

Water Sampling and Testing

Opal’s technicians can take water samples and run tests for a variety of bacteria, viruses and contaminants, as well as checking suitability of drinking water.


water disinfection

Chlorination keeps hot and cold water services free of microorganisms such as bacteria, viruses and microbes. This process can be carried out preventatively, if any suspected contamination has occurred, or if a system has not been used for a period of time outside of the recommended usage.

Water Treatment Log Books

Log books are used at sites to record and closely monitor information relating to your water supply. As well as Health & Safety measures, they are used to communicate to staff the importance of water hygiene and control, as well as record roles and responsibilities.
