What is a pilot project?

Pilot projects are temporary small-scale projects that evaluate the effects of a technology at an existing wastewater treatment facility. After a side stream of water undergoes treatment that uses the technology in the pilot, the department tests the water and returns it to the existing facility for regular treatment. Before a pilot project can begin, the department must approve the plan for a pilot project as well as the testing protocol. See 10 CSR 20-6.010(1)(B)8.

What is a demonstration project?

Demonstration projects are full-scale installations of technology not addressed in 10 CSR 20-8; in Great Lakes-Upper Mississippi River Board of State Sanitary Engineers Recommended Standards for Sewage Works or in other widely published design guides for wastewater treatment.

Unlike pilot projects, demonstration projects do require construction permits and operating permit modifications. Before a business may obtain a construction permit for a demonstration project, the department must approve the plan for the demonstration project and the testing protocol for the treated wastewater.

What innovative technologies has the department found acceptable?

The following technologies are acceptable if the effluent from the wastewater treatment facilities meet the criteria established in installations currently achieving acceptable biochemical oxygen demands (BODs); total suspended solids (TSS) and ammonia removal.

Approved technologies include the following:

What innovative technologies has the department been assessing?

The department is reviewing the following technologies:
