Improved infrastructure in St Neot has resulted in a 30% decrease in storm overflow spills in 2025 compared to 2024. This is part of South West Water's £16 million Infiltration Reduction Programme, which aims to prevent groundwater infiltration into the sewer network.

Engineers implemented trenchless repair methods, sealing manholes and internally lining 200 meters of sewer pipe. This minimizes disruption and strengthens the sewer system. Additional upgrades included a new control panel and updated pump operations to maintain consistent performance during wet weather. The work targets 175 high-risk sites, with 900 meters of sewer pipe surveyed for further improvements.
