Smaller desalination plant to be constructed first

SOUTH West Water’s plans to deliver desalination in Cornwall as part of its investment in long-term water resilience across the region have taken a step forward, as it announces it will deliver the scheme in two phases.

The company says it is investing £125 million to increase water resources in Cornwall and Devon by 2025 to break the cycle of drought. This includes plans to deliver a climate-independent source of water to customers in Cornwall through a new desalination plant in Par.

Focusing on the pressing need to secure resilient water supplies,

South West Water says it will deliver a smaller plant later this year, using existing infrastructure to avoid any impact to the marine environment.

This plant will be capable of producing up to five million litres of clean drinking water each day when needed, and will allow more time to develop the application for a larger desalination plant.

South West Water says it is working closely with experts to “continue understanding the marine and natural environment in St Austell Bay to achieve this and remains committed to this outcome”.

The proposed larger desalination plant will replace the smaller one and reuse as much of the existing infrastructure as possible to produce up to 20 million litres of drinking water daily.

David Harris, South West Water’s drought and resilience director, said: “Our current reservoir levels may look healthy following a wet winter and the interventions we and our customers have made, but the impact of climate change tells us we need to be more resilient to drought.

“Regulators are encouraging water companies to develop supplies that are resilient to the impacts of climate change, and desalination is one important step in a wider programme of work we are delivering to ensure resilient supplies across our region in the face of a changing climate.

“We share the passion that many locals have shown to protect the sensitive marine environment in St Austell Bay. Taking more time to fully understand this environment will allow us to enhance our proposals and be sure that we are doing everything we can to minimise any impact we have to marine habitats. We have been developing our plans to be consistent with other proposals for development for the area.”
