Proposed Project Team and Experience The treated effluent from the process wastewater treatment facility is used for noncontact cooling for controlling temperature during the malting process and for cooling of a conference room and an employee meeting area prior to discharge to the Minnesota River. All of the projects were completed ahead of schedule and within budget. Wastewater Treatment Facility, Saint Peter, MN (2004) Contact: Lewis Giesking, Public Works Director, 507-934-0771 The City of Saint Peter and Bolton &Menk, Inc. worked together over a 10-year period to develop and implement plans for an advanced technology wastewater treatment system incorporated into a single structure that meets the needs of the City of Saint Peter for years to come. i The City of Saint Peter operated the largest stabilization pond treatment -° system in the state. This facility, located in the flood plain of the Minnesota - River,was inundated with floodwaters on numerous occasions. Due to the environmental impacts of these flood events,the City began work to relocate the wastewater treatment operations.This planning was further accelerated by the 1998 tornado,which created the need for rebuilding much of the city's infrastructure. IA site within the city's industrial park was chosen for the wastewater treatment facility,maximizing the use of existing public infrastructure and city owned property. Bolton&Menk, Inc. developed a practical and cost-effective plan using new technology— Biological Aerated Filters (BAF) and parallel plate clarifiers for wastewater treatment, and lime heat stabilization for biosolids treatment. The compact size of the treatment processes allowed for the facility to be constructed within a single structure,meeting public expectations.The system removes BOD, ammonia and phosphorous below standards. The lime/heat pasteurization process treats biosolids to a"Class A"level. This process reduces the amount of storage required for biosolids and increases the options for biosolids disposal and reuse. In addition,the following wastewater treatment process improvements were implemented: new lift station and forcemain;new grit removal and screenings facilities;new UV facilities; new outfall; new on-site dewatered biosolids storage facility;new standby generator; odor control facility; and a new computer control system. The project was completed on time and within budget. Saint Peter's new facility complies with the wastewater discharge limits for the Minnesota River.This facility serves as a successful new model for implementation of wastewater treatment technology.
