    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.

    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!

    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.
