When to pour foundations

I have my foundations dug out, but there is a lot of water collecting in the trench (from non stop rain!), when is it safe to start to pour the foundations?

Get as much of the water out as possible and pour the concrete a.s.a.p...or you may see the side of the trenches collapsing.

Firstly before you pour the concrete BCO need to inspect trenches, find your lowest spot and dig a small sump hole, drop in a dirty water pump and pump out all water, all sludge etc will need to be cleaned out, get bco to inspect and pass then pour the concrete, sooner the better before your trench sides start caving in.

its best to have all water out of the footing before you pour, this can be done with a sub pump.
once water is pumped out any soft earth/clay should be skimmed of with the spade, if rain keeps on filling trench, dig a small well for the pump to sit in, then control the amount of water/ rainfall by flicking on / off pump to suit.
this well want's to be at the lowest point and best if its where your last bit or borrow of concrete will be going. take out pump just as the concrete gets within a metre of the pump.
then stand well back and say to your self "job well done"
