Severn Trent Water will hold a public exhibition at Cheltenham Town Football Club next Thursday where it will sets out plans for the latest phase of a £5 million upgrade to improve the sewers and help to prevent sewer flooding throughout Cheltenham.
Wayne Ellis, solution manager for Severn Trent Water, explained:
“We’re investing heavily in Cheltenham to make sure our customers are better protected from the terrible impact of sewer flooding and we’ve made good progress with our work so far.”
He said attendees would be able to meet the team and that Severn Trent in turn wanted to hear the local community’s views as the company relied on local knowledge to help minimise the impact of the work.
The work, which will be carried out by Severn Trent’s contract partner NMCNomenca, is due to start in late November. The contractor maintains a dedicated website which is regularly updated with progress on its work in Cheltenham.
In addition to the £5m investment Severn Trent is making in Cheltenham to alleviate sewer flooding resulting from a lack of capacity in their sewer network, the firm is also investing a further £750k to address structural defects in sections of pipework. This work is called Cheltenham Sewer Rehab, and will involve the rehabilitation of defective lengths of sewer.
NMCNomenca will be carrying out the work between now and February 2015 at 37 different locations around the town, where investigations have identified sections of the network that do not meet the required standards. The sections need to be improved to eliminate the risk of future collapse, resulting in blockages, flooding and pollution.
For most of the sections NMCNomenca will be using a technique which is called Cured-in-Place Lining. The technique involves re-lining the sewer with a resin-impregnated felt sleeve which is inserted in the pipe between existing manholes, and inflated by filling with water so that it expands to fill the pipe.
The resin in the sleeve is then cured by circulating boiling water through the water until the sleeve becomes rigid and strong, and supports the defective pipework. After the lining has cured the water is drained from the sleeve, and any side connections to the sewer are re-opened with robotic remote-controlled cutting equipment to restore flows from lateral connections.
With the UK government demanding a 50% reduction in storm overflow spills by 2029, the era of reactive management is over. Speaking in the House of Commons on 21 July 2025, then environment secretary Steve Reed said, “This Government will cut water companies’ sewage pollution in half by the end of the decade.”
