I'm on creating cohousing community in the mountains of western NC and one of the core challenges I see is how to deal with waste treatment. We are looking at land outside of town and thus which does not have access to town water/sewer. The common practice for individual homes outside of town is of course to use septic tanks and drain fields. However I see problems with this for a tightly clustered project (with say 30 units clustered on 5-6 acres) because the size of area required for the consolidated drain fields. Here in the mountains, any reasonably flat land is at a premium for the houses and then other amenities like gardens and orchards and thus using this land for drain fields is not very attractive. I've looked into various treatment options that require somewhat smaller footprint such as sand-filter systems and constructed wet lands but these appear to be relatively quite expensive (in the range of ~$15K per unit). Has anyone working with rural cohousing projects found good solutions for this challenge? Thanks, Lynnwood Brown
