broadex Posted January 25, 2022 Share 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 Share 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 Link to comment Share on other sites More sharing options...
JohnMo Posted January 26, 2022 Share Posted January 26, 2022 Have a look at the kingspan website that should give you some ideas. Plenty of companies with solutions. 1 Link to comment Share on other sites More sharing options...

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 Link to comment Share on other sites More sharing options...
Mr Punter Posted January 26, 2022 Share 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 Link to comment Share on other sites More sharing options...

There is however for ceptic tanks. 1 Link to comment Share on other sites More sharing options...

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 Link to comment Share on other sites More sharing options...
