SCOTTISH Water has broken ground on a multi-million pound project to upgrade the waste water treatment system in the Midlothian village of Edgehead.
The project, which the organisation said will see the installation of ‘market-leading’ treatment technologies, is designed to improve the quality of treated water being released into the environment.
Hybrid submerged aerated filters, supplied by WCS Environmental Engineering, will be installed on the existing site. They will biologically disinfect the waste water by enabling micro-organisms to break down organic matter and potentially harmful nutrients.
The filters will be buried below the ground and, thanks to their design, take up around 30% less space than traditional treatment processes while also being more efficient. Due to the modular construction of the filters, they will be built offsite – reducing the on-site construction time and causing less disruption to the community, Scottish Water said.
Colin Freeland, project manager from Caledonian Water Alliance, Scottish Water’s alliance partners, said, “The current works at Edgehead has served us well however, it is not able to meet the modern standards required of it. We are delighted to be installing a technology which can be buried out of site, minimising the visual impact on the community. It will improve the quality of the treated waste water leaving the site and will ensure that we are able to continue providing a high quality service to the community for many years to come.”
