Opal work closely with property managers, taking the responsibility of inspection visits, closed system water treatment and chlorination of plant room tanks, with a clear line of responsibility for upkeep. Our water service contracts ensure that the quality of water supplying the property is safe for the residents to use and by carrying out regular inspection visits we can ensure that any issues found are reported and dealt with immediately.

Our Water Treatment Services

Our engineers work quickly and efficiently to ensure minimal disruption to your properties, regardless of the work we’re doing. Our services include:

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 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.

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.

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 Tank Refurbishment and Replacement

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