Engineered Concrete Structures’ waterSHED™ System Aids City in Meeting Looming EPA Deadline

SAMSUNGThe City of North Olmsted, OH is nearing completion on a two-phase Collection System and Wastewater Treatment Plant (WWTP) Improvement Project. The project would meet the Environmental Protection Agency’s (EPA) requirements to eliminate collection system overflows before the end of the year. Areas of the city were plagued by sanitary sewer overflows during periods of intense wet weather from infiltration/inflow intrusion. To avoid sewage backups flooding into residential basements the city was forced to pump raw wastewater from its sanitary sewer system into its storm sewer system.

As part of Phase II of the project Engineered Concrete Structures (ECS) of Cleveland, OH was responsible for installing a 625,000 gallon underground flow equalization tank at the Dover Pump Station. ECS’ waterSHED™ is a design-build cast-in-place concrete structure that can serve as a primary or secondary containment system for a number of functions including liquid storage, sanitary equalization, and storm/sewer detention. The waterSHED™ system can be tailored to accommodate a smaller footprint in densely populated neighborhoods where space is limited. The system satisfies a number of design and construction standards including the EPA’s National Pollutant Discharge Elimination System (NPDES) permit program as well as ACI 350. During Phase I of the project, ECS installed a 1.25 million gallon underground equalization facility at Clague Park located under existing soccer fields.

SAMSUNGThe underground equalization facilities installed by ECS will work in conjunction with a number of other improvements including the installation of parallel relief sanitary sewers, the rehabilitation of two pump stations and the expansion of a third pump station along with numerous improvements and enhancements to the WWTP. Construction on the entire project is expected to be complete by the end of the year to meet EPA mandates.

ECS is an engineering and concrete construction company that specializes in the design and cast-in-place installation of various infrastructure-related reinforced concrete structures. For over 40 years they have been engineering and building concrete structures such as tank systems, retaining walls, bridges and 3-sided and 4-sided box culverts. ECS has completed projects throughout the United States.
