Hydrostatic Pressure Testing, Chlorination & Sampling

Hydrostatic Pressure Testing, Chlorination, Dechlorination and Sampling Services

Conroy Group operates fully equipped hydrostatic pressure testing vehicles supported by experienced operatives familiar with regional water company requirements and industry standards. Pressure testing, chlorination, dechlorination and sampling services are undertaken to verify the integrity of newly installed water mains, service connections and pipeline infrastructure prior to commissioning.

Using specialist equipment and proven testing procedures, pipelines can be assessed for integrity, leakage and operational performance before being approved for connection to the drinking water network.

Pressure Testing for New Water Main Installations

Hydrostatic pressure testing forms a critical part of the commissioning process for new water mains and pipeline infrastructure. Testing verifies that pipework, fittings and joints can withstand operational pressures whilst identifying any defects or leakage before the network is placed into service.

Services are regularly undertaken for water companies, developers, self-lay providers and infrastructure contractors across a wide range of clean water projects. Testing can be carried out on new installations, diverted mains, replacement networks and rehabilitation schemes.

Hydrostatic Pressure Testing, Chlorination & Sampling

Working to industry standards (IGN-4-01-03) the maximum capacity can be established with any leaks identified and ultimately a confirmation of its ability to withstand pressure verified.

Our on-site data logging download systems allow immediate results to be presented and overall pipe performance to be evaluated in real time. This means that potential problems can be detected and identified saving time and money. The results are available as soon as the test is complete, and all background data made available for any additional review.

Once the pipe has been tested and verified a process of chlorination and dechlorination can begin in order to ensure the pipe is clean and ready for connection to the drinking water supply system. With specialist dosing and dechlorination equipment pre-agreed parameters are adhered to in order to prepare the system for water sample laboratory testing and approval to connect into the public drinking water domain.

Supporting Water Main Commissioning & Network Approval

Following successful pressure testing, chlorination and dechlorination procedures help ensure the pipeline is clean and suitable for connection to the public water supply. Water sampling is then undertaken in accordance with the relevant requirements before final approval and commissioning.

By providing pressure testing, chlorination, dechlorination and sampling services as part of a complete water infrastructure offering, projects can be progressed efficiently from installation through to final connection and handover.
