How do I pipe the water coming out from sub pumb into my back yard or outside sewer & what size piping to use?

Question

I can either drain it to my backyard and if so how deep into the ground must I dig for the drain line not to get frozen in the winter, or I think I can drain it into the sewer line.

Answer 1

In some areas you can not pump it into a sewer line. To keep that extra water out of sewage treatment plants some localities ban that connection.

You need a "dry well." Dig a hole about the size of a 55 gallon drum in your back yard not near the house. Get a drum and perforate it with a cold chisel so water can drain through it. Put it down in the hole. Fill it with gravel. put the end of the drain pipe into the open top and back fill around it with pea gravel. Then pack sand around the sides and add a garbage can lid on top and cover the top with soil.

Use a regular 4" PVC pipe for the connection.

Expect it to have life of 5-10 years before you need to dig it up and clean out silt in it.

Does anyone else in your area have the same problem? If you are getting more water than you have flushed or drained elsewhere in the house then it is definitely the main that is clogged, and the responsibility of your water/sewer utility. If you are getting only what you have flushed or drained elsewhere, then it is your responsibility. Typically, residential sewer laterals have vents at the street trap. Do you have such a vent, and is any water showing there? If so, most likely you do have a utility main problem. Either way, take pictures and keep a record of any damages for your Insurance Company. If it turns out to be a Utility issue, the pictures will help you making a claim for any damages. You can get a sewer plug at a plumbing supply or Home Depot-type store - it is a black plug that you put in place and inflate to seal the pipe or drain. Or the ball, if you can get it in tightly enough.

Answer 3

A lot has to do with where you live as to where the frost line is. Call some one in the local water department they should they know how far to bury pipes. Before you leave the phone call the sewer department about dumping sump water into the sewer line. I doubt it! The amount of water that dumps from that sump in a given period will tell you how large a drain bed you need. If it doesn't matter about just dumping it on the ground you have saved a step.

Answer 4

What's a sub pumb? Do you mean SUMP PUMP? Pump it out to the street 2" line.
