A proposed £1.2bn scheme to recycle effluent from the sewage system and turn it in to drinking water has been criticised as a threat to the environment and a potential costly “white elephant”.

Southern Water wants to treat effluent – wastewater from the sewage system – at a plant at Havant in Hampshire and pipe it into a nearby spring-fed reservoir to boost water supplies during droughts. The scheme would ensure less water is extracted from two rare chalk streams: the Rivers Test and Itchen.

It would be the first reservoir in the country to use recycled water derived from effluent to supplement its levels. Regulators says effluent recycling is successfully used overseas, providing plentiful and safe supplies, but campaigners say there are more environmentally friendly options.

    From the article:

    Bob Comlay, who runs the Havant Matters website, which details community concerns, and who is also vice-chair of the Solent Protection Society, said construction work to build the plant on the former landfill site risked contaminating groundwater which would flow into the Solent. There are also concerns about the environmental impact on the marine ecology of rejected contaminated water discharged into the sea.

    He said a Thames Water desalination plant which used the same technology had been mostly inactive since it was opened. “This is a vanity project,” he said. “It will be a white elephant.”
