St Erth Sewage Treatment Works

There have been intermittent complaints about the ‘pong’ coming from the Hayle Sewage Treatment Works at St Erth for many years. In recent times, the situation seemed to have improved but in June 2017, Derek was contacted by local residents concerned about the smell and other issues at the plant.

Timeline

30th June, 2017

Derek hosted a meeting at the treatment works with St Erth residents, parish councillors and SWW personnel including Ed Mitchell, Pennon’s Director of Environment, and Guy Doble, SWW’s Director of Wastewater Recovery and Treatment.

The group toured the site and it was clear that a particularly noxious smell was coming from an ageing tank; other concerns included the difficulty in contacting SWW about odour issues, light pollution at night, early morning noise pollution and the need for camouflage screening where trees had been felled.

Action points to deal with these points were agreed by SWW, including the need to invigorate the Odour Liaison Group which did not work as effectively as other groups in the South West. The ageing tank is due to be replaced in September, 2017.

A staff member from Derek’s office attends a meeting of the Odour Liaison Group. Cledma Bank residents report that the number of occasions when a bad odour has been detected has reduced – although in part this could be due to the cooler, autumnal weather.

Progress was reported with regard to the installation of a Sewage Related Debris (SRD) storage unit, a covered skip on the Start pad to allow screenings to be deposited into a covered area and the likely date (March 2018) of a new Sludge Storage Tank.

Discussions are ongoing between the EA and SWW regarding the production of an effective Odour Management Plan for the plant.
