In almost all areas, that's not allowed.
No gray water or black water to discharge outside of a sanitary sewage collection system.

Hey Dom, Thanks for your help. This was in a county I normally don't work in. The city inspector I was able to finally speak with said the same thing.

Have a super day and thanks again

"In almost all areas, that's not allowed."

Dom is correct in that it depends on what the sump is for. If it is a sanitary system lift station then it would be allowed ... although it would not be allowed for that purpose if done as shown.

In towns like Lombard, Elmhurst, almost all of the suburbs around Chicago, they had the sump pump pits handle rain water from the drain tiles and the laundry water. At the time these were set up this way the pumps discharged into the sewer. Back in the late 1980's (1986-87) lots of these cities and villages, wanted the rain water to be separate from the sanitary sewer. So everyone was required to discharge the sump pump pit outside. Since laundry water is not allowed to be discharged outside people had to have the laundry drain to a ejector pit or at least a pump in a box.

So if that pump pit you have pictured is only handling the laundry and no rain water and is pumping into the sewer, its allowed. If its handling both drain tiles and laundry it is not allowed.

Here is the state code, this should help a lot.

Section 890.1360 Sanitary Wastes Below Sewer

a) Sanitary Wastes Below Sewer

1) Sanitary wastes which cannot be discharged by gravity flow shall be discharged into a gas-tight, covered and vented sump from which the waste shall be lifted and discharged into a sanitary waste drain by automatic pumping equipment. (See Appendix J: Illustrations K and L.)

2) Sumps and ejectors handling sub-soil drainage and footing drains shall not receive any sewage. Sumps and ejectors handling sewage shall not receive subsoil drainage and footing drains.

Hi Ron: Thank you so much for your very informative info. The pump is currently use for both. So they will have to correct the problem since they will need a plumber for other issues anyway. Thanks again.. Fidel
