UV treatment selected for care home wastewater

Technology from water recycling specialist WCS Environmental Engineering (WCSEE) has been selected by a care home in Cornwall in the UK to provide onsite wastewater treatment in an environmentally sensitive location.  
Trevaylor Manor is situated in Gulval, two miles from the town of Penzance.
As it is not connected to the public sewer, the property is served by an onsite wastewater treatment plant. 
With the existing system coming to the end of its operational life, the soakaway it had historically discharged to was no longer deemed suitable. A new point of discharge, to a nearby brook, meant more stringent Environment Agency permit conditions were stipulated, requiring enhanced levels of effluent treatment.  
After close liaison with installer Jones Drainage & Groundworks and WCSEE, the care home’s owner, private care provider Swallowcourt, opted to replace the plant and add a tertiary stage of ultraviolet (UV) treatment.
WCSEE has designed a custom onsite solution comprising a below-ground HiPAF® - high performance aerated filter - treatment plant and UV disinfection system with a capacity of approximately 300 population equivalent (PE).  
WCSEE technical manager Dominic Hamblin said: “We are pleased Trevaylor Manor has selected our technology for its new onsite treatment plant. 
“The end result will be a modern, reliable and robust system that will treat effluent to the very high standards required in this environmentally sensitive location. UV disinfection will provide maximum bacteria and virus removal rates, and therefore give the highest levels of protection to local water environments.
“The combination of HiPAF treatment and UV is usually only required when the receiving waters are particularly sensitive. The advanced process gives peace of mind that effluent has undergone rigorous treatment and will meet full compliance.”
Steven Jones, of Jones Drainage & Groundworks, said: “This is an important project to protect the local environment in the beautiful village of Gulval. The site has very tight access but because WCSEE’s HiPAF technology is modular and built-off site, we will be able to use a crane to position the units.”
Mike Tippett, Swallowcourt estates and contracts manager, said: “We are proud to be located in this beautiful part of Cornwall and take our environmental responsibilities very seriously. Our upgraded treatment plant will ensure we can continue to treat our wastewater onsite without impacting the environment.”
