Lakeside Engineering designed a commercial septic system for the Sauder's Store, Inc., located in Seneca Falls, NY. The store is under construction for a 35,000 square foot expansion. Due to poor draining soils a sand filter system with a modified absorption trench was designed. A 1,000 gallon grease interceptor and 2,000 gallon septic tank with an effluent filter were required. In addition, the grades at the site were not conducive for a gravity system. An alternating Gould pump station was designed to convey the wastewater to the sand filters.
