WASTEWATER
CFS provides design and management for sanitary sewer projects for county, municipal, and private clients with expertise in interceptor sewers, gravity mains, force mains, Sanitary Sewer Evaluation Study (SSES), I&I removal, pump station design, and stream and aerial crossings. From a building to a treatment plant, CFS is committed to providing cost-effective design solutions for new and rehabilitated sanitary sewers and pump stations. We work with our clients to protect natural resources from hazardous waste, eliminate higher treatment costs, and meet regulations for pipelines, lateral lines, and manholes. We provide long-term solutions that meet current and expected future environmental requirements. By maintaining good working relationships with regulatory agencies, we work to receive timely approvals and therefore timely projects.
PROJECTS
Pine Street Sanitary Sewer Line
Wellsville, Kansas
The VCP line was badly deteriorated with multiple fractures, partial collapses, and significant sags which resulted in stagnant sewage and smell complaints. Located at a depth ranging from 10 to 15 feet, CFS had to work around many existing features including existing accessory structures, trees, and fences. CFS completed planning, survey, and design for 620-foot of 8-inch sanitary sewer replacement and 660-feet of rehabilitation using interior lining. CFS’ scope included acquisition of easements, removal and replacement of pavements and sidewalks, relocation of utilities, grading, erosion control, traffic control, and signage.
MSU Baker’s Acres Observatory
Sanitary Sewer Design
Kansas City, Missouri
The existing site is in a rural part of Webster County, northwest of Marshfield, Missouri. This campus has a sanitary sewer system that has inadequate capacity during events held at the Bakers Acres Observatory. The existing facility hosts events that bring approximately 100 visitors, but a future expansion is planned that would allow 500 to 1,000 visitors to the site.
The university had a very small budget to work with and the area has no public sewer system nearby. This scenario left options for a septic system or sewage lagoons. The university was opposed to lagoons, so a septic system design was chosen. The area draining away from the observatory is a dense woodland and was not suitable for a large leaching field, which presented a design challenge for CFS.
Since these large events at the observatory occur only 6 to 8 times a year, CFS proposed a septic system with a septic tank, retention pumping tank, timer, dosing and leaching chambers to meter the drainage flow dosage out over several days to reduce the size of the drain field. Using a distribution box with leaching chambers provided significant storage retention over traditional lateral field piping. Using this design, we were able to service up to 600 users at a 3000 gallon per day capacity with the capability to expand in the future for larger events at the observatory.
CFS provided soils evaluation, analysis for site locations, engineering, technical specifications, bid documents, permitting and on-site inspection for the project.
