Knollands Septic Tanks & Drainage

Avon Vale Hunt

Avon Vale Hunt

A septic tank and a Bio treatment tank are to be installed at the Avon Vale Hunt to serve two houses and the kennels. The septic tank which was a Kingspan Klargester Alpha 3800 litre is to be used as an interceptor to stop any unwanted solids from the kennels reaching the treatment system. The area being currently used to treat the effluent is extensive starting with an old septic tank followed by a large read bed area and soak away system and this will be greatly reduced. Some of the main problem with old style septic tanks is they can be draining the local area back into the tank, roots may have blocked the soak away system and a direct discharge with a sealed system makes sense. This system is reasonably priced, low maintenance and easy to install

Due to the growth and expansion of this caravan site the existing septic tank systems have needed to be upgraded. A Proffesional Ocean 100 plus was supplied with an Ammonia treatment level to cope with 1200 gnh3/d. This system included a primary settlement system similar to a septic tank and a humus settlement tank. Also included were low energy saving device, alarm, blowers, sample chamber and kiosk. The discharge target was along the standard 20-30-20 BOD, suspended solids and ammonia levels. Caravan sites whether static or touring are normally served by their own septic tanks and treatment systems and our range of products are used nation wide to treat and dispose of effluent discharge.

Bourton on the Water

Bourton on the Water new developments

Two large private dwellings next door to each other needing discharge into the stream. With the unique lock down system to hold the tank in the ground and the CE standard certificate guaranteeing water standards the Bio-pure was the preferred option over other tanks. Both properties had existing brick septic tanks that were in need of replacement. Due to the high water tables pumped outlets were installed within the tanks to stop water back flowing into the tanks when flooding occurs. One of the properties required the tank to be installed in a drive way. A designed concrete surround and access shaft allowed this to take place.

Grand Designs first certified Passivhaus in England. Knollands septic tanks and drainage supplied a Bio-Pure 3 septic tank for 12 people with deep invert along with our Graf soak away tunnels for this extremely interesting and individual project that will be featured on Channel 4's programme 'Grand Designs'...

"Aesthetically, even though the site is in a very prominent location at the top of a hill in the Cotswolds Area of Outstanding Natural Beauty, the design of this house is very bold. Being dug into the hill to be invisible from the surrounding countryside, this is essentially a stealth house, with absolute minimal visual as well as environmental impact on landscape."
