On-site wastewater disposal systems provide an important, economically efficient, and relatively clean and healthful method of wastewater disposal in areas of the municipality not served by an integrated sewage collection and disposal system. Upon suitable percolation rate, we provide septic system design (both primary disposal field and secondary disposal field) according to MOA Chapter 15.65 Wastewater Disposal Code. Our design complies with MOA regulation and will be approved by MOA for construction.
