Septic rules in Allegan County

Allegan County's septic rules are the Allegan County Water and Sewage Regulations, approved October 23, 1997 and in effect since November 20, 1997, enforced by the Health Officer in every city, village and township. Nobody may construct, alter or extend a system without a construction permit. A permit expires one year after issue, can be extended a year if you ask before it runs out, and does not transfer to another person or place.

Tanks must be pumped often enough to keep solids out of the absorption field, and only a licensed pumper may remove sewage. The regulations text names no sale requirement, but the Environmental Health Division, at 3255 122nd Avenue, Suite 200 in Allegan and (269) 673-5415, takes applications to evaluate an existing system at a transfer of ownership. Its form asks you to locate the tank and show it was pumped in the last three years, and excavation and pumping costs are yours.

The form lists $275 for well and septic and $225 for septic alone, but it dates from 2018, so ask for the current fee. Allegan has no city of its own in our set, but Holland, with 34,266 residents and 63.6 percent of homes built before 1980, spans Allegan and Ottawa counties. If your Holland address lies in Allegan County, the Ottawa County entry does not apply to you, so ask the department which county's rules govern your parcel.
