Cold Water Tanks

What we do

Cold Water Storage Cisterns

We maintain high water quality standards for our clients with cold water storage cisterns, either as part of a routine legionella management programme, or as a standalone requirement.

Initial Assessment

We can provide an initial condition assessment including volume, turnover and compliance with the Water Regulations. Where necessary we can also design and install replacement tanks.

Confined Space Entry

As part of our commitment to high health and safety standards our experienced site teams are fully City&Guild qualified in confined space entry and the provision of safe access systems.

Cleaning & Disinfection

Routine cleaning and disinfection is carried out quickly and efficiently to keep any disruption to a minimum. We work to current industry standards PD 855468:2015, BS EN 806-48558 and BS 8558.

Water Quality Sampling

All water quality samples are submitted to a third party UKAS accredited laboratory for analysis of bacteriological and/or legionella parameters.


On completion we supply a fully detailed certificate with times, volumes and laboratory results. This clear audit trail is supported by a record of before and after digital images.
