iSelfBuild Posted July 31, 2017 Share Posted July 31, 2017 I will be buying a BioPure 3 soon for our log cabin developments and I will need to pump the treated effluent up to the drainage field. 55m and about 1 - 1.5m head. They offer a pumped outlet but at £400.00 I'm wondering if I should DIY this as the drainage consultancy fees for getting the system passed and buying soil (as ours failed the test) has drained my wallet! From what I can see it's just a tank with a submersible pump in: Diameter 1250mm Overall height 1510mm Capacity 1.84m3 Looking at the price of underground water tanks I might as well just pay the £400? Did anyone have any luck negotiation with BioPure/WeBuildIt? Link to comment Share on other sites More sharing options...
Jeremy Harris Posted July 31, 2017 Share Posted July 31, 2017 (edited) We have the pumped outlet Bio Pure. It's more than a tank with a submersible pump in it. There is a separate chamber inside the tank, with a weir that takes the liquid off the top of the main treatment tank, from the outer zone where the effluent has been treated (so clear from the recirculating bubble chamber in the central "tank within a tank"). The submersible pump sits in this clear effluent chamber, with a float switch. When the clear effluent level rises to the point where the pump is triggered, it then empties the clear effluent chamber in around 20 seconds. This clear effluent chamber also has an alarm float sensor, as the pumped system comes with an alarm unit that senses both air pump pressure and the level in the pump chamber. The pump that's in the clear effluent chamber is a fairly standard stainless submersible unit, fitted with a float switch and a rigid pipe connection that connects to the outlet (50mm MDPE) via a two lever bayonet quick release. This rigid connection keeps the pump positioned in the centre of the clear effluent chamber, and the quick release makes removing the pump pretty easy.

If you don't mind me asking how much was it? I am only guessing it's £400 off the website. Edited July 31, 2017 by iSelfBuild Link to comment Share on other sites More sharing options...
Jeremy Harris Posted July 31, 2017 Share Posted July 31, 2017 I can dig out the invoice tomorrow, but have a feeling it was around £300 or so more than the base unit, but we bought ours over three years ago now. 1 Link to comment Share on other sites More sharing options...
ProDave Posted July 31, 2017 Share Posted July 31, 2017 If your soil failed the percolation test, have you looked at filter mound systems? They are a pile of graded sand placed above ground and then covered with soil. I looked at those as a solution for our drainage, but in the end building control rejected it and we ended up getting permission to discharge to the burn instead.

Thanks, did you manage to dig out the invoice? We just got some grit/soil approved at £15.00 a tonne EX haulage. Link to comment Share on other sites More sharing options...
Jeremy Harris Posted August 2, 2017 Share Posted August 2, 2017 I've just checked, and we paid £2,275 for the Bio Pure, with the pumped outlet and alarm system. Link to comment Share on other sites More sharing options...
