Project Summary

Klingner provided a Preliminary Engineering Report for submittal to the Missouri DNR and the Missouri Water and Wastewater Review Committee for funding and approval. The project was funded by Missouri DNR-SRF with a 25% loan and 75% grant. This treatment facility is set up to handle future limits for total nitrogen. As part of the alternative evaluation process for treatment, Klingner evaluated “no discharge” options such as drip irrigation and spray irrigation. To meet ammonia effluent limits, one cell of the existing 3-cell lagoon was modified into a mechanical treatment facility.

Other work consisted of sewer collection improvements, including lining and replacement of sewer mains and lining and replacement of manholes to correct I / I problems in approximately 70% of the sewer collection system. Over 120 manholes and approximately 20,000 LF of sewer mains were either lined or replaced. Cured in place pipe (CIPP) and cured in place manholes (CIPM) were used to address repairs without significant excavation and costs. I / I flows were cut approximately 80% by the repairs completed in this project.

Klingner also assisted in obtaining a Rural Sewer Grant from Missouri DNR to pay for half of the cost of adding a liquid chlorination / dechlorination disinfection system at the lagoon treatment facility. Klingner provided the planning, engineering report, design, bidding, construction administration, and construction observation services for the addition of chemical feed equipment, a chlorine contact tank, and an effluent flow meter for the 120,000 GPD lagoon treatment facility.

Klingner has a current project to upgrade the lagoon treatment system to meet ammonia requirements; reduce infiltration and inflow in the sewer collection system; and prepare a Capacity, Management, Operations and Manual (CMOM) for the sewer system. Funding sources include Missouri DNR-SRF Grant and Loan funding, and the project is 75% grant-funded.
