broadex Posted January 25, 2022 Posted January 25, 2022 I have got a site where the main sewage is uphill - about 2 metres from the bottom of the site- where a proposed dwelling will be. I'm told planning office are not keen on pressurised pumps. Just wondering any ideas to take into account before i engage an engineer - this is just a planning in principle so trying to get the costs down.
ProDave Posted January 26, 2022 Posted January 26, 2022 Is this connecting to mains sewage? the usual solution is just a holding chamber and a pump, sometimes 2 pumps for redundancy. 1
JohnMo Posted January 26, 2022 Posted January 26, 2022 Have a look at the kingspan website that should give you some ideas. Plenty of companies with solutions. 1

It’s a building regs issue so don’t even bother including it in any plans. When you get planning, you’ll need to work out where to site a pump station (usually between 12-1600 litres depending on the number of bedrooms/WCs) and then that pumps to a chamber that is above the sewer level and gravity takes over. The tank needs to be minimum 3m from a house IIRC. Where in the UK are you..? 2
Mr Punter Posted January 26, 2022 Posted January 26, 2022 You will just need to run the uphill section from the pump station in different pipe. The only issue I have found is getting it to lie flat in the trench, especially in cold weather. 1

Think Scotland have a rule on it but can’t remember anything from the guidance in the BStd without looking (but it is only guidance not a regulation at that point) 1
