South West Water has boosted the resilience of its wastewater network in Exmouth with a new 1.4km sewer designed to protect the town’s coastline and communities for years to come.The bespoke pipe, which has been specially made for this project, is more than 13 times the length of Wembley football pitch and carries flows from Maer Road Pumping Station to Maer Lane Wastewater Treatment Works, where wastewater is treated before being safely returned to the environment.

South West Water’s teams have been working for over seven months to install the new sewer, which offers greater resistance to wear, higher pumping capacity, and improved resilience against ground movement. These features will reduce the risk of bursts and provide a reliable wastewater service well into the future.

“This is a big step forward for Exmouth and after months of hard work by our teams I’m really pleased that the new sewer is now providing long-term resilience,” said Jay Harris, Director of Wastewater Operations for Exmouth. “We do not underestimate the disruption that recent issues with the old pipe have caused to local residents. Between this work and other investments we have planned for the area, we’re proud to provide a more reliable and robust service which protects our customers and our environment.”

Alongside planned upgrades to Maer Road Pumping Station and Maer Lane Wastewater Treatment Works, the new sewer will help reduce storm overflow use by increasing the volume of flows that can be pumped to the works for treatment during wet weather.

The new sewer represents the latest chapter in Exmouth’s long history of wastewater improvements, dating back to 1890 when the town’s first storage tanks and pumping station were built at Sheppard’s Row to prevent sewer flooding.
