Scottish Water and Veolia Water UK, the operators of the Seafield Waste Water Treatment Works will continue to monitor the facility for any potential odour issues following the completion of the multi-million pounds Odour Improvement Plan.
Construction began in autumn 2009 and was completed in summer 2011. The works is undergoing a strict monitoring regime which is being carried out by a number of environmental regulators.
We have kept the local community and its elected representatives fully informed, and met regularly during the construction programme. We have continued to keep them updated.
The Odour Improvement project involved the installation of two new Odour Treatment Units, ductwork and support bridges, new coarse and fine inlet screens, channel covers, weir covers at Primary Settlement Tanks and improvements to the detritors which are now capable of removing fine particles of grit - reducing the risk of blockage and potential odour generation.
The plant is capable of producing up to 2300 kilowatts of sustainable electricity. Offset, this is enough to power up to 600 homes. This is produced by gas powered generators which use the gas produced in the 6 digesters on site to generate this ‘green’ power.
The facility is managed on our behalf by Veolia Water UK, one of the world’s leading environmental services providers, under a 30 year Private Finance Initiative contract which has been running since 1998.
As part of our ongoing commitment to keep all stakeholders informed about odour sensitive activities at Seafield Waste Water Treatment Works (WwTW) we wish to inform you that commencing Wednesday 27th February, Seafield WwTW operators Veolia Water will drain and clean the Storm Tanks in a planned and controlled operation lasting up to 7 days. Veolia have programmed the operation to minimise odour risk. Weather and operational conditions will be closely monitored and reviewed throughout this activity as will dialogue with Council Officers who will continue to respond to odour complaints whilst continuing with their community based monitoring and assessment programme.
In parallel to this operation, planned and phased maintenance has commenced on part of the sludge thickening stream together with the clean out of an on-site sludge pumping station. In order to ensure operations continue as normal whilst this maintenance work is undertaken temporary replacement thickener will be commissioned today. This work is scheduled to last for two weeks In line with the site Odour Management Plan, Veolia have undertaken an odour risk assessment of this operation and shared the information with Scottish Water and regulators.
