WLSSD is committed to providing effective, reliable services to the communities and industries we serve. Capital improvements are made to better meet the needs of our wastewater and solid waste customers; and investments are paced in a manner that helps to stabilize rates.
Long-term capital planning for WLSSD’s large regional wastewater system is based on ongoing condition assessments and strategic plans to ensure that the timing of investments is aligned with WLSSD’s needs and goals. Improvements for the WLSSD’s solid waste facilities are aimed at meeting the needs of the region’s solid waste customers and reducing the amount of waste sent to landfills.
Wastewater capital investments paid for through current revenues, bonding and low-interest loans made possible through the U.S. EPA Clean Water State Revolving Fund administered by Minnesota’s Public Facilities Authority. Solid Waste capital investments are paid with current revenues, and through loans to finance infrequent large infrastructure projects.
Current Infrastructure Project Highlights
WLSSD will rehabilitate nearly 1 mile of its 42-inch diameter Scanlon Interceptor on Highway 61 near Thomson Township, MN with cured-in-place lining (a seamless pipe-within-a-pipe). The project will cost $3.2 million.
WLSSD will replace its obsolete, 40-year-old pure oxygen production plant and portions of its electrical distribution system to improve reliability, efficiency and safety. The nearly $20 million project also prepares WLSSD for future on-site generation of electricity. (see below: Biogas: Harnessing Energy from Wastewater)
Funding for these projects is provided through loans from Minnesota’s Public Facilities Authority, made possible through the Clean Water State Revolving Fund (CWSRF). CWSRF funds are provided through federal legislation, and passed on to states by the U.S. EPA.
WLSSD will install generators to produce electricity from the methane-rich “biogas” created during the wastewater treatment process. WLSSD will use the electricity generated and heat captured from the process to control costs and increase the resiliency of wastewater treatment operations.
