As part of our Self Build Planning Approval we are required to ‘hold back’ surface water from discharging immediately into the Public Sewer. I am struggling to find an alternative supplier to Hydro Brake, who supply expensive and heavy concrete manhole chambers. Ideally, there would be a plastic manhole chamber which is easier to install on site. Any leads/advice would be much appreciated!

    Just an update for everyone.

    The major suppliers were quoting me £2500 plus vat for a plastic water flow restrictor and £2000 plus vat for a concrete version. Delivery times of 3-4 weeks.

    After a few weeks trawling the internet I managed to source a plastic water flow restrictor for £450 plus Vat. The local planning and building control officers have approved this product.

    The company is based in Bury. I placed the order on a Tuesday and it was delivered to site on Friday of the same week.

    I am over the moon!!
