Vendor pitches on-site wastewater systems as Marshall County board weighs sewer options

A vendor from Sledgehammer described an on-site wastewater treatment system to the Marshall County PSA 1 sewer board and residents, saying the modular units can be retrofitted into many existing septic tanks and billed as a lower-cost alternative to community sewer connections.

“My name is William Satter. I’m president of Global. We are an innovative and alternative technology for on-site water and wastewater filtration,” Satter said in his opening remarks, describing a biologically based aerobic unit his company manufacturers and a new local partnership with AK Industries.

The proposal drew questions from board members and county staff about which properties would qualify, local permitting limits and whether state rules allow local health departments to grant setback variances that would be needed on many lakefront lots.

Why it matters

The board is working through a proposed, multi‑million-dollar sewer project for PSA 1. Board members and residents said a conventional sewer would be expensive, disruptive and take years to build; the vendor argued on-site treatment could reduce capital and landscaping impacts and keep treated effluent on property for reuse.

Details from the meeting

Satter said the Sledgehammer system has regulatory approvals and third‑party testing he said include NSF 40 (new design residential applications), UPC/IAPMO listings and maritime (MARPOL) certifications for certain uses.…
