Dry well backed up! New Build?

This is a kitchen sink/ dishwasher dedicated dry well, ten feet away from the house. Backyard slight downward pitch. I have only seen the cement top, which is about 3-4 feet diameter. (Looks real heavy.) I donít know how deep it is. House was built about 1950, I have lived here 23 years and never had an issue.

I am thinking about avoiding any investigation and digging a separate new Dry well, 20 plus feet away from the house. This may be easier to redirect the copper drain coming about a foot from the house with a new connection, thus also avoiding the older style nonmetallic black pipe which is what connects it to the existing dry well.

Do I need to vent or try and leave a future access to new dry well? The PVC pipe will be about 1 foot or deeper slight pitch and the dry well about 3 plus feet deep by 3 wide with black mesh under rock base to prevent dirt build up.

Any suggestions or confirmation would be welcome. THX

A new drywell for gray water may or may not be permitted. The usual alternative is routing the waste water to your septic tank.

Drywells fail in the same manner as septic system leach lines. Grease and/or fine particulate matter clogs the soil just outside the perimeter of the drywell.
