Leave Plenty of Space for Maintaining Your Composter! When locating the composting toilet system, consider how it is going to be maintained and emptied. You must provide an easy-to-clean area with easy access to outdoors for removing compost. If the system will be maintained by a sewage hauling company, make sure the company’s equipment can access the composter. It’s best to consult the sewage hauling company before you install the composter.
