Simply put, the Biocell Domestic Concrete+ is a reinforced concrete septic tank. But due to the reliable and robust structure, it is suitable for areas with vehicle traffic or livestock. The innovative design combines a three-stage treatment process into one single packaged plant.  It is both EN12566-3 and  SR66 certified and British Water approved.

 In addition to the standard model, there are gravity and pumped outlet models available. Unlike many other septic systems on the market, our reinforced concrete tank is suitable for below ground or above ground installation in all soil conditions.  In situations where an existing septic system is outdated or failing, we can easily replace it with our Biocell Domestic Concrete+. Also, there is no need for a concrete backfill, or expensive installation works. On a final note, the Biocell Domestic Concrete+ boasts very high effluent quality in combination with low running costs.


There are many reasons behind the success of the Biocell Domestic Concrete+. The homeowner can benefit from the low set up and running costs, and installation is quick and easy for the builder or installers. The following is a short summary of the benefits of choosing this system;

  • Shallow dig tank for easy installation

  • Watertight tank
  • Low running costs

    Very big tank. Value for money. Was going to buy from a local concrete lad – but the local guy seems to make tanks, fence posts, paving slabs, etc, and was not very knowledgeable – so decided to go with a specialist supplier as want a good aftersales service.

    Great job. Dropped in the hole with the crane.

    A different system was recommended by my architect. Shopped around and bought a biocell concrete and saved a few pound. Architect was also happy when he saw the unit installed.

    Purchased for my new home in Ireland. Its one of the only tanks on the market that does 8 pe in a single nice round tank. Didnt want a two tank system as its extra connections and hassle. Very good job. A local concrete guy had a concrete tank on offer also – but I wanted to deal with a company that will still be there in 20 years!

    Frank Bourke

    Wanted concrete but didn’t want to buy from the local guy as he is a one man band so no backup if he stops selling/retires/is on holidays. Went with Biocell and glad I did. Good product and they supplied manhole extensions for free.
