Process designed to meet stringent environmental discharge permit

The underground installation at Juliots Well in North Cornwall will replace the existing septic tank and includes a HiPAF (high performance aerated filter) modular treatment plant.

Civil engineering specialist Aqua-Tech Consultancy made the initial contact with WPL and together the parties arranged a client visit to see a similar installation at Home Farm Holiday Centre in Somerset. The new 1,230 population equivalent system will process up to 181m3 wastewater per day without impeding on the site’s sweeping views of the Cornish landscape.

Technical director, Andrew Baird, said, “We have a strong track record in providing wastewater treatment for sensitive locations where integration with the landscape and the expectations of visitors are top priorities.

“We are very pleased with this contract win, which will meet the needs of this stunning site now and into the future as visitor numbers increase. We are already working in close collaboration with the client and consultant to understand the specific needs of Juliots Well and deliver the best value whole-life cost.”

Design considerations include ensuring that the stringent Environment Agency effluent discharge permit for biological oxygen demand, suspended solids and ammonia is met. The system will also accommodate variations in load as visitor numbers rise in the peak season and fall in the winter months.

Juliots Well Holiday Park is a rural retreat set in 33 acres of countryside near Camelford and is owned by South West Holiday Parks, part of the Worldteam Limited group. Installation of the full treatment system is taking place at the end of the 2019 holiday season.

The HiPAF sewage treatment system will comprise of three biological treatment tanks and two final settlement tanks along with a flow measurement chamber with monitoring equipment.

A global system for mobile communications (GSM) will be incorporated into a special control panel covering blowers, sludge pumps and a high-level alarm. An extra-large kiosk will house the controls and will feature a flashing alarm beacon.

Worldteam Limited’s managing director Josh Donald said, “We are passionate about providing our visitors with a first-class experience, while ensuring that we minimise our impact on the landscape and the environment.

“The opportunity to see a similar HiPAF treatment system in operation has been very helpful in visualising the project. I look forward to seeing the new system in place and serving our customers as we grow.”
