Northumbrian Water starts final phase of £5m bathing water quality scheme

Northumbrian Water is starting work next month on the third and final phase of a £5 million scheme to improve bathing water quality at Saltburn.

The two-and-a-half-month phase of work will begin on Monday 10th August  and will involve transferring waste water from Dunsdale sewage treatment works (STW) to Marske STW. The scheme includes the installation of more than 110 metres of new sewer pipe and the construction of a new surface water drainage gully.

When waste water arrives at Marske STW, it will be treated and also disinfected with ultra violet light before being discharged to sea through the existing long sea outfall. Waste water which is currently treated at Dunsdale STW is discharged into Skelton Beck.

 The Dunsdale works will then be decommissioned in October, once the transferred waste water is being treated at Marske STW.

The overall, one-year scheme began in December last year and the other phases of work have involved building an underground storm water storage tank, which will hold up to 6,000 cubic metres of storm water, on the former Guisborough sewage treatment works site. Storm water will be pumped to Marske STW for treatment, once the storm has passed. Northumrian Water said this work is progressing well and will be complete by December this year.

Work to increase the pumping capacity at Tocketts Bridge pumping station, so more storm water can be transferred from Guisborough to Marske STW when it rains, will be finished next month.

Steve Gray, Northumbrian Water’s project manager, said:

"The Saltburn bathing water scheme will significantly reduce the frequency and volume of spills to water courses from the sewer network, during times of heavy rainfall, and will make an improvement to the quality of water in local streams and rivers and also to sea water quality.”

To identify the best solution to improve Saltubrn’s bathing water quality, the water company worked in partnership with the Environment Agency and Redcar and Cleveland Borough Council to carry out a detailed investigative study in the whole catchment of Skelton, Brotton, Boosbeck, Lingdale and Guisborough. Northumbrian Water said this approach was vital as there are many sources of pollution which impact on Saltburn’s bathing water quality, including pollution in Skelton Beck, Saltburn Gill and Pit Hills Stell from cattle, sheep and pig farming, rainfall run-off and pollution from private sewage treatment works.

The water company’s  £1 billion investment, over the last two decades to improve bathing water quality was reflected in last year’s bathing water results. The North East’s results were the best in the country - 31 out of 34 beaches in Northumbrian Water’s region, including Saltburn, met the current strictest European water quality standard.
