Precast concrete sump/drain

[Landrover]

As part of a catchment sensitive farming grant i have a yard to concrete and there is a drain to put into it and was wondering if you can buy such a thing ? Like a settlement tank that could be cleaned out ? Any help would be good !

We made one by digging a hole and suspended a rectangular wooden former held by two cross members over the top , these were fixed down to prevent floatation / movement.
We also cast in a galvanised angle surround which had fish tails welded on to tie it in to the concrete , the formwork fastened inside this .
We had mesh spaced in the gap then just filled around with concrete , make sure the formwork is very strong and also hasn't flexed the angle frame outwards .
You could also make one with four panels , a reinforced concrete base and have galvanised angles in the corners.
You would dig a hole place a spot of concrete in each corner to level , once cured set the panels up then mesh and pour the base , slightly above the bottom of the panels.
The cover used was similar to a cattle grid except with 60x60x6 box section at close centres rather than tube.
To clean it out you obviously just lift the cover off and use a digger.

Yes there are. Try Jkh for their ready made concrete chambers

Make sure you can clean it out with the loader rather than a slurry tanker.
Cast a concrete box with a slope you can drive the loader front wheels down to clean out the sump
