Underground sewage works project begins today

Yorkshire Water will today begin construction on a £1.8M project at Ingbirchworth, near Barnsley, to create an underground sewage treatment works.

The company is creating the new underground facility to replace its current above-ground sewage treatment works, which has served the local population since the 1960s.

A two-fold increase in the size of the local population over the years has meant the existing plant is now over capacity.

The new plant will be smaller in size and bigger in capacity than the current facility, and will be capable of receiving 10l of wastewater per second.

Yorkshire Water said the new plant’s underground design means the risk of odours from the site will be massively reduced.

The current facility’s site will be returned to grassland. The new works will be up and running by March next year.

A Yorkshire Water spokesman said: “Building an above-ground replacement treatment works would have been far easier than installing an underground facility, but the benefits this subterranean works will bring in terms of it not being visually obtrusive, whilst also massively reducing the risk of odours at the site, made this the best solution.”

  • An early underground treatment works was built at Swanage, Dorset, in limited space and with minimum disruption. Completed June 2000. Some seaside resorts have no option but to place a collector tunnel somewhere near the shoreline and then pump back up to treatment. I think Poole may also have installed one around 1968.

  • Does the new plant (including pumping costs into and out of the treatment works) require a much higher energy input to complete the cleaning process to convert sewage into water clean enough to be discharged into the river system?
