CTRL groundwater to be sold as drinking water

News

MILLIONS OF litres of groundwater pumped from the Channel Tunnel Rail Link site in east London are to be sold as drinking water, project manager Rail Link Engineering (RLE) said this week.

Water companies will be invited to bid for the water, which will be removed from a 10km section of the project to ease tunnel construction.

RLE has already started installing hundreds of pumps capable of removing the water at up to 500 litres/second along this section of the project.

The water will be pumped from depths of 25m over a 10km section of the project which includes the Stratford station box. It will then be sent via pipeline to a water treatment works before it is added to the water supply.

The water is already close to potable standards and will require minimum treatment, said RLE.

RLE is to invite water companies to bid for the water. Bids are likely to include proposals to build pipeline links to treatment works.

Under the original plans groundwater was to be pumped straight into the nearby Roding and Lea Rivers as the project was not allowed to get rid of it via the sewer network.

Selling the water was eventually chosen as a more lucrative option.
