Camp Onomia: Onamia, MN

Camp Onomia is a church camp located on Shakopee Lake.  The Camp was required to do a system update. A previous design proposal called for large mounds that would have caused extensive damage to the wooded portion of their property.  The camp has a kitchen, which serves three meals per day.


  • Septic Check redesigned a system that uses pretreatment to reduce drain field size, thus enabling the dispersal system to fit between the trees.
  • Some of the existing collection and tanks were compliant and were reused.
  • Kitchen waste is pretreated using aerobic treatment units. It then mixes with the balance of the camp’s wastewater for additional treatment before dosing to long, narrow drainfields in the woods.
  • Our design build saved over $300,000 from their original estimate.
