Mobile home park seeking permit to upgrade septic system

Sherburne Country Mobile Home Park seems to be getting closer to finally having its septic system upgraded as the state is mandating.

The Minnesota Pollution Control Agency is conducting a Sept. 25 to Oct. 25 public comment period in which people can comment on the MPCA’s intent to reissue a state disposal system permit the park’s owners. The mobile home’s old permit expired March 31 last year.

It has been about five years since the state told Michael Wadsworth, then owner of the mobile home park, that he needed to upgrade the wastewater septic system at the park that sits on the south side of Sherburne County Road 2, just south of Princeton city limits.

Wadsworth had the option of either upgrading the septic system or hooking into the city’s Wastewater treatment system, and it looked at one point like the park was going to be annexed and hooked into the city sewer system.

Baldwin Township Supervisor Jay Swanson had even once weighed in on how the mobile home park might get an upgraded septic system. Swanson had talked about developing a wastewater treatment plant in the township that would serve the mobile home park.

The Princeton City Council told Wadsworth that to hook into the city’s wastewater system, he would have to pay $591,250 to extend the city’s sewer main to the park, plus pay the city’s $927,450 sewer access charge.

Wadsworth had gone so far as to sign a petition for the annexation as the first step toward the sewer hookup, leading city officials to think the annexation was going to proceed. But Wadsworth backed out just before the annexation process gained traction, and later sold the mobile home park to Kent and Leyvi Titcomb of DeLand, Fla., according to the park’s manager, Janell Whitcomb. MPCA’s notice of intent to reissue the new permit lists the permit applicant as Amicorp Communities, LLC, 400 Nut Tree Drive, DeLand, Fla.

The Becker-based land surveying and civil engineering firm Bogart, Pederson & Associates is involved in the design of the septic system upgrade. The firm is also the engineer for Baldwin Township.

The specifications include:

• An 8-inch gravity collection system attached to one main duplex lift station.

• An Amphidrome treatment system consisting of one septic or anoxic tank with a static volume of 18,000 gallons and an additional 4,300 gallons of fluctuating volume for the filter backwash and nitrate recycle.

• One submerged and attached growth bioreactor, which would provide 1,070 cubic feet of sand media that would alternate between down-flow and up-flow with intermittent aeration.

Filtered water would enter the clear well, which would backwash the reactor and dose the drain field. The drain field would have two dispersal fields, each having two cells for a total installed drain field area of 16,640 square feet. An additional area would be designated adjacent to the drain field for possible future use in the system.

The reactor would be sized for a future flow of 24,000 gallons per day, with the remainder of the system sized for the current flow.

Public actions that are allowed during the public-input period include submitting written comments, petitioning for a public informational meeting or petitioning for a contested case hearing. That third action would be in front of an administrative law judge.
