About this article
No stormwater system available. Contractor suggests connecting foundation (perimeter/French) drain to septic tank. Soil is mostly flat with poor slope. I’m concerned about overloading the septic system, backflow risk, and long-term performance. Would this be considered bad practice? What are safer alternatives? submitted by /u/Past_Park_4097 [link] [comments]
