- Project Name: DaVinci Academy Onsite Wastewater System
- Project Location: Ham Lake, MN
- Client: DaVinci Academy of Arts and Science
Project Challenge:
Providing wastewater treatment and disposal system for a site that is not serviced by a regional sewer line. The onsite system had to meet nitrogen limits, which required advanced secondary treatment.
Environmental/Regulatory Factors:
The project design and operation is reviewed and permitted by Minnesota Pollution Control Agency (MPCA).
Options considered:
Onsite Wastewater System with primary, secondary, and partial tertiary treatment with soil disposal system. The project includes a septic tank, recirculation tank, AX100 Unit, MBBR, dosing tank and seepage beds.
Solution:
At full buildout, the proposed Kindergarten through 8th Grade school will have a population of 1,200 students and staff. The Peak Wet Weather Design Flow is 10,850 gallons/day and the Average Daily Flow is 6,000 gallons/day.
Result/Performance Data:
The system has been in operation for over four years and is meeting all applicable limits as required in their permit from the MPCA.
