I assume this is the best place to post this. I am wanting to build a bath house in the backyard for my pool. Problem I have is getting sanitary sewer to the only location I can feasible build my bath house. I think there is enough fall for a gravity fed sewer system but I will have to go through several landscape areas and gravel areas. I have been considering a grinder pump system with a force main or a self composting toilet. Anyone else had this same dilemna and figured out a solution. Also if any of you have pics of your pool houses please post for info.
