Sumps

[local patios and driveway]

im doing some land drainage today and the architect has specified 300mm catch pit sumps. any idea if i can buy these off the shelf for the client? ive seen concrete ring ones but they seem a bit overkill for the domestic setting.

What about an IC raising section bedded into a concrete base with the pipework cut in through the side?

We are doing similar dan .built in brick in the end

Pre-formed road gulley plastic former would be cheaper/quicker, surrounded by concrete?

loads of options, you can buy preformed ones but expensive, as has been said lots of things work

we did one last week 5 4" dense block in a slab to act as the pit then broke them out, or ive set carver boxes full of sand in as a shutter before then concreted round them,

thanks all, chris, i mentioned brick to the client, the obvious advantage is cleaning it out, that said a few ic rings on concrete base would be cheapest i guess, they sell a basket too that sits internally so it can be emptied.

We suggested rings dan . Council didn't want em . had to build them in brick . They are 1.2 m deep as well

I had one made by express plastics, all they did was chop a chunk off a 600mm twinwall solid drainage pipe, plastic weld a bottom onit and then core two holes out and weld some spigots on, cost about 100 quid i think

Edit...thinking about it, i think it was more, but it was the cheapest option by far
