Condor Pipe glides to the rescue
A 300mm foul water pipe was 75% deformed along with significant root infiltration with further structural defects upstream causing a risk of bank erosion, landslides and damage to badger setts along with residential properties. PSS devised a way to mix, match and adapt a methodical system to repair the pipe with little impact to the environment.
The works were completed in a fraction of the time, significantly reducing the budget cost to the satisfaction of the client, stakeholders and residents.
Watertight Management Ltd / Severn Trent Water – Camers Green Mains Renewal
The Camers Green project started in November 2019 with the purpose of installing 8,825m of new water mains replacing the existing, ageing 3in, 4in and 6in AC & CI water mains.
Watertight Management Ltd carried out the work on behalf of Severn Trent Water Limited as part of their mains replacement programme with a target completion date of April 2020 in order to meet their leakage and burst criteria.
The detail design and environmental support was provided by Severn Trent Water Limited’s framework suppliers.
There were numerous highways, private land, customer and environmental challenges.
Wessex Water / Onsite Ltd – Weymouth Saline Intrusion Sealing
As an 18-year high astronomical tidal surge approached the sound coast in July 2020, Wessex Water identified chloride spikes via saline ingress into the sewers, around the historic harbour in Weymouth Dorset. As the sea water took advantage of defects in the 600mm trunk sewers, the process at the Radipole sewerage treatment centre would be affected.
Within a few weeks of appraisal, a £450k scheme by Onsite Ltd, sealed 700m of sewers and adjoining manholes, on cost and ahead of programme. A sustainable matrix of solutions meeting high standards of H&S compliance, over a continuous framework partnership of 20 years.
