Septic rules in Eaton County
Eaton County's septic program belongs to the Barry-Eaton District Health Department, which also serves Barry County. The department's septic page names a Sanitary Code and an appeal application but shows no adoption date, and the pages hold no time-of-transfer rule that we could see, which says nothing about what the department requires. The FY2027 fee schedule lists $469 for a new-construction sewage permit, $523 for a replacement system including its site evaluation, $260 for a tank-only permit, $1,135 for a low-pressure dose mound and $1,333 for an alternative system in new construction, with double fees for a system installed without a permit.
Conventional systems do not need a certified installer. Low-pressure dose mounds over slowly permeable soils, lagoons and alternative pretreatment systems may be installed only by installers the department certifies, for $207. The department's homeowner tip is to pump typically every two to three years, which is advice and not a mandate. Applications, complaints and records requests run through an online portal, a Septic Tank Pump Card form is posted, and the page mentions Michigan Saves loans.
A site evaluation looks at the distance to wells, surface water and county drains and at how near public sewer is, and tile to a drain, lake, stream or field tile is not a sewage system. Waverly, in our set, has 23,301 residents, and Lansing also reaches into Eaton. See the alternative systems guide.
