Chlorination & Dechlorination

Essential for disinfecting new or existing pipework before commissioning. We provide full chlorination, contact time monitoring, sampling, certification, and safe dechlorination to ensure water quality meets regulatory standards.

Hydrostatic Testing

The most common and effective method for pressure testing water pipelines and it involves filling the pipe or component with water and increasing the pressure to a test pressure, holding it for a predetermined period.

Leak Detection

Hydrostatic testing is excellent for identifying larger leaks, but for issues that may not be immediately apparent during a standard pressure test, we also offer specialised leak detection services to pinpoint smaller, hidden leaks.
