No. I have a leach-tank instead of a leach field, for my septic. The laundry currently drains into a dry-well. The only difference between a dry-well and a leach tank is the size of the chamber. Liquid drains into them and dissipates into the earth like a leach-field. Laundry dry-wells eventually get saturated with detergents and drain slower and slower until they are effective clogged. The leach-tank is large enough to last another century at least. By then I wont care.

Neither is legally acceptable for new installations. Existing examples are "grand-fathered." Modification is a gray area and I will be checking with code enforcement on that. Mine are 50+ years old and the septic/holding tank is newer.

I dont want to access the holding tank. Just send the gray water straight to the leach-tank. I dont really need any advice on the practicality of that. I am satisifed that it is workable subject to the frost problem.

My town's code-officer is "user-friendly" and if the project is legal will tell me what I need to tweak, to remain in compliance. He's advised me on other projects and will tell me if it's a lost cause before I make a major investment of time or labor. I just prefer to have more info before I bother him so I will be able to answer his questions.

Thanks.
