Septage disposal for haulers
For over 30 years, the District has provided valuable septage disposal treatment service to rural homes and businesses in Dane County and the surrounding region. To ensure the integrity of our wastewater, pumping companies and septage haulers are issued a permit by our pretreatment coordinator before they are allowed to utilize this service.
To apply for a permit, complete the Septage Hauler Permit Application and mail forms to:
Madison Metropolitan Sewerage District, Attn: Pretreatment Coordinator, 1610 Moorland Road, Madison, WI 53713.
