Pressure Testing Data Logging
Prior to connection of a new mains water pipe, the majority of water utilities companies require proof that the new mains pipe is solid, secure and does not leak. Water Utility companies must adhere to strict guidelines and procedures which are now in place for pressure testing. Pressure testing requires specialist expertise. We are seeing in more cases complete data logging and graphical analysis is also required.
Water Supply Regulations
The Water Supply (Water fittings) Regulations 1999 require that all new water systems, both above and below the ground should be tested hydraulically prior to commissioning.
Pressure Testing
Water Utility companies have strict rules for pressure testing. Pressure testing requires specialist expertise. Pressure testing also needs satisfactory evidence, which in most cases requires full data logging and graphical analysis.
Pressure test results are collected using a pressure/recording device. This allows the user to take accurate pressure readings. Pressure readings should be taken throughout the test. It is also important to avoid interference from the pumping action. The data loggers are calibrated to ensure accuracy every time. They also take into account other elements such as temperature, which can affect the recorded pressure in a pipeline. This means a thorough pipe assessment is always required.
Pipework Variations
The method of pressure testing will vary depending upon the nature of the pipework. Systems with plastic pipes need to make allowance for the expansion in the plastic material caused by the pressurisation process.
Data Logging
The data logger can also contain GPS positioning, which makes it easy to connect the test results to the pipe being assessed.
Water Utilities Approval
To carry out a pressure test using this method, the test results including the pressure decay graph must be forwarded onto the relevant water utility company. Northumbrian water, for example, now requires data logging on all size mains with more than one joint regardless of the diameter.
