Our drains at work run into a cesspit and the rainwater runoff is meant to go to a soakaway in the forecourt.

This is all a bit of guesswork as the building was built in the 70's and we can't find any drain layout plans.

Is there anyone local that would be able to come and take a look to see if that's correct?

My concern is that we seem to be generating roughly 1,300 gallons of waste a month into the cesspit which seems exceedingly high so I'm wondering if some of the rainwater is going that way as well. If it is I'll cut the bottoms off the downpipes and let it run across the ground.

The average family of four will discharge about 800 gallons of waste per week.

This includes toilet, general bath/shower and utilities.

When connected to a standard 1000 gallon unit with a functional soakaway or drainage ditch outlet this should only need to be emptied every 9-12 months.

Base your calculations on that and see what you come up with. laugh

Surface water should be a separate entity but it is not unknown for builders to take a shortcut and run it all into the waste pipes.

Well cutting down the downpipes will make the water spread all over the ground and I think leaving water that way would anyway create problems. Instead you can get the your drainage distributed in some other sublets but I would still recommend you to take some advice from expert or if you don't know anyone in your local then contact water removal Denver experts. Hope they will get that sorted out.
