What is electrical sewage treatment?
Unlike septic tanks which settle out solids and then discharge untreated septic effluent to a soakaway, sewage treatment systems treat the effluent so that what comes out of the system is water that is safe to enter our rivers, streams, ditches and ground water. You could say that sewage treatment systems receive raw sewage and discharge river water.
Compact and reliable
Most domestic sewage treatment plants are extremely compact and can be installed on the smallest of sites. WCI has a wide experience of installing sewage treatment plants in small gardens, under driveways, within existing septic tanks and even above ground. All of the systems we install are BS EN12566-3:2005 certified and we guarantee regulatory compliance.
No soakaway required
There are many reasons why you might need sewage treatment. One common reason is because septic tanks cannot legally discharge directly to a watercourse (or ditch) and subsequently require a soakaway. For properties with limited garden space, high water tables or soil with poor porosity (eg. clay), soakaways are not viable. Treated effluent from a sewage treatment plant, however, can legally be discharged (subject to Environment Agency guidelines) into watercourses and ditches.
Sewage treatment systems can sometimes appear expensive to buy and install. However, with sewage rates for the average family home costing around £540 per year, private sewage treatment is considerably cheaper over the medium to long term.
The chart to the right illustrates the average cost over 15 years for a 3 bedroom house.
The WPL Diamond is an ‘activated sludge’ range of package sewage treatment plants serving a population ranging from 6 – 55 PE. A single tank system, wastewater flows directly into the main tank and enters a bio-chamber where the biological process begins. The bio-chamber is an aerated zone where solids circulate and are thereby treated. The Diamond provides for a number of depth extensions and can be applied in circumstances where the depth of incoming drains would prevent other systems being used.
WCI likes the Diamond for its robustness, the quality of its blower housing, its consistent treatment quality and the well-designed and sympathetic lid. Click here to download the official Diamond brochure or call us for more information.
The Conder ASP is an ‘activated sludge’ range of package sewage treatment plants serving a population ranging from 6 – 25 PE. A single tank system, wastewater is treated in an inner central bio-zone chamber and an outer settlement zone. The plant accepts and treats the incoming sewage, using the extended aeration principle, in the central bio-zone chamber. A simple coarse bubble diffuser, housed in a draft tube, introduces the air that provides the oxygen to the bacteria which then treats the sewage. The bio-zone retains the mixture of sewage and bacteria until the level of treatment has been achieved. The treated effluent then enters the settlement zone where settlement takes place. The treated (final) effluent subsequently leaves the plant over a weir at the outlet level that extends around the circumference of the tank. The movement of fluid through the whole system is by gravity displacement and there are no moving parts in the treatment plant.
WCI likes the ASP for its ease of installation, reliability in high water tables and consistent treatment quality. Click here to download the official Conder ASP brochure or call us for more information.
The Rewatec Solido is a ‘sequence batch reactor’ range of package sewage treatment plants serving a population from 6 to 40 PE. Wastewater is treated in batches rather than being treated continuously making the Solido an efficient treatment plant with reduced energy consumption and prolonged life for all component parts.
A sequence batch reactor plant offers significantly greater control over treatment than an activated sludge plant. This can eliminate noise at crucial times (eg. peaceful summer evenings), reduce running costs (eg. when the family is on holiday) and deliver high levels of treatment (for stringent discharge standards).
WCI likes the Solido for its efficiency, ability to control noise and its robust and sympathetic construction. Click here to download the official Rewatec Solido brochure or call us for more information.
The Klargester BioFicient is a ‘submerged aeration’ range of package sewage treatment plants serving a population from 6 to 30 PE. The BioFicient is a single tank system and has been specifically designed for ‘shallow dig’ applications. The moving aerated media process is a compact development of the traditional biological process and provides high levels of treatment.
WCI likes the BioFicient for its shallow dig credentials and its unobtrusive design features. Click here to download the official Klargester BioFicient factsheet or call us for more information.
The Klargester BioDisc is a ‘rotating biological contactor’ range of package sewage treatment plants serving a population from 6 to 24 PE. The BioDisc is the only sewage treatment plant utilising the ‘RBC’ technology more typically found in large applications for domestic applications. The BioDisc is subsequently a high performance package treatment plant which in normal domestic situations will produce effluent qualities of better than 8mg/l BOD, 13mg/l SS and 4mg/l ammonia.
WCI likes the BioDisc for its treatment quality. Click here to download the official Klargester BioDisc factsheet or call us for more information.
WCI is an independent company. We will always recommend the best sewage treatment plant to meet your requirements.
Part of establishing the quiet, family-orientated Newton Brook Caravan and Camping in Somerset was to design a Building Control and Environment Agency (EA)-compliant foul drainage system. We employed WCI Sewage Treatment Ltd to liaise with the EA after we found ourselves out of our depth when the bespoke permit application we submitted was questioned. After talking through our issues with the very knowledgeable Naomi, WCI guided us through the process and a permit was awarded with a 5 ammonia standard. WCI went to tender for the most suitable system for our site and WPL designed the system. David Trump of WCI oversaw the installation of the large 400 pe. HiPAF System by our own contractors on a Saturday in April 2016. The installation was smooth and its operation has been faultless. WCI have been pivotal in getting our site up and running and open to the public. David has a wealth of knowledge gained from working all around the world, he is also very good at baking so I would suggest this is mentioned at the time of booking the first site meeting. We would not hesitate in recommending WCI.
Newton Brook Caravan and Camping, Somerset, April 2016
“Many, many thanks for such a brilliant job which David managed brilliantly on the day and reduced my stress levels no end! It might seem silly to hear, but it is SO good not to have to worry anymore as to how many times the toilet is flushed, or how many showers are being taken – which has been a constant stress for over 10 years. I wish I’d done it a lot sooner. Best regards to all at WCI and thank you so much.”

“We were very pleased with the professionalism and care taken by David Trump and his team in installing a Conder Sewage Treatment Plant. His dealing with the regulatory bodies was also very much appreciated. We would highly recommend WCI Sewage Treatment to anyone considering a new, or replacement sewage treatment plant.”

“We were recommended to WCI Sewage by Biorock and are pleased to say that it was a very good recommendation to have. Naomi and David answered queries either by phone or email promptly and pleasantly. The installation proceeded smoothly starting early on the day agreed and finishing on time. David took care of contacting building control and septic tank emptying so there was nothing we had to organise separately. The men were always on site early and easy to get on with.”

“Thankfully we engaged WCI to advise us with the design for our replacement domestic sewage system, and the advice, knowledge and positive approach from both you and David was invaluable. You have been extremely patient with us and the weather. The treatment plant and reed bed were simple to install and construct and at long last we have a system that not only works but it works really well! It was a welcome relief to find a local company to help us, thank you for all that you did.”
Bovey Cottage, June 2013
“David’s advice and clear explanations from the start were reassuring. The team were punctual, efficient and got on with the job: everything you’d want PLUS they landscaped the area, leaving it better than it had been before the job was done. We are very pleased with the end result.”
