Dallas, TX- pump rain water through DE sanitary sewer pipe?

[texasmax]

All-

So I've got a yard drainage problem. Specifically, whether the house was built this way or got this way through erosion/shifting over time, I've got a low point in the yard where I collect an awful lot of deep standing water after a storm. There are some yard drains but the pipes have either clogged/broke/become non-functional over time. I'm thinking I'm going to install a sump pump to pump the water out. This low area is very close to the house, as well as the pool equipment. I've got a dedicated DE backwash drain pipe that (presumably) goes to the sanitary sewer (can't imagine it's the storm sewer). Short of installing a new underground line to get the water pumped up and out, I was debating pushing the water into the backwash drain pipe (with the appropriate one-way valving in place). The pipe is 2-inch PVC. The pump would have to run enough head to get the water pressurized at some point to handle whatever elevation changes the pipe has including the final upside-down U where it comes up out of the ground and back into the sewer (across the air gap). Is this a bad idea?

Howdy TexasMax-

I can't comment on your proposed plan, but have you ever considered putting in a rain garden there in that low spot??

tex,

I'm pretty sure that putting runoff water into the Sanitary Drain (sewer) is illegal...

I have a house in Farmers Branch... I backwashed into the street and was written up by the city saying I had to backwash into the Sanitary Drain... At the same house there is a French drain and a sump pump. The sump pump had to be plumbed to the street and could not be plumbed into the Sanitary Drain...

Thanks for posting,
