Opal work closely with facilities management companies to support your maintenance services with industry-specific knowledge, consultancy and hygiene contracts. We can accompany you on customer visits to discuss their requirements and how we can help.

Water Treatment Services UK

We provide reports with all of the work we carry out and can take specific photos if required.

We offer several water treatment services to facilities management businesses to keep your sites’ water supplies clean and safe:


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 Plant and Equipment Maintenance

The equipment required to treat and manage water: its storage, hardness, cleanliness and temperature, all needs to be maintained to high standards for safety and compliance. Opal can support with supply and installation of new equipment to water testing, ongoing servicing and remedial works. 

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.

Water Tank Refurbishment and Replacement

From surveys to refurbishment and installation, Opal can help you maintain your water tank.

Closed System Testing and Flushing

Because closed systems are sealed and contain a fixed volume of water, they can be neglected until they start to malfunction. We can test, flush and monitor your system to ensure it works correctly.

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.


If you would like to speak to Opal about how we can help you manage the water safety and hygiene at your sites, just give us a call. Our in-house consultant engineers have years of experience, and can offer consultancy for specific problems or simply to provide a thorough understanding of compliance and issues that need to be monitored.
