McBreen Environmental offer a nationwide service for integrity testing of sewers and water pipes. Here are some images from our Team based in Cork who recently completed drainage and manhole integrity testing on storm & foul sewer network at a Recycling Centre.
What does integrity testing involve?
In this case, two types of testing were undertaken:
- Air Testing – where the lines are ‘bunged’ off and pressure tested with Air. This mainly checks for any leaks in the pipes.
- Hydrostatic Water Testing – involves filling the manhole, testing the water levels and recording any variances over a 30-minute duration.
Both tests are completed in line with EN1610 Standards which are in full compliance with EPA & other regulators’ guidelines.
Did you know?
Any business that holds an Integrated Pollution Prevention and Control (IPPC) licence has a requirement to test the sewerage network on a 3 year cycle. Testing provides assurance that the structural integrity of the drain/sewer/manholes for waste, process or storm water flows are up to the standards required. Ensuring the environment is protected by preventing any possible leakage from the network.
What happens where a line or manhole fails?
A CCTV survey is completed using the most up-to-date equipment, the CCTV footage is reviewed by trained and experienced engineers to establish why the lines have failed. The Client is provided with a detailed report and our recommendations on the most suitable rehabilitation work, whether that be localised patching/repairs, manhole or drain relining etc.
Once the lines have been rehabilitated a full re-test is completed. Testing Certificates are downloaded in a pdf form and provided to the Client for evidence of compliance with EPA audits.
