SME provided geotechnical evaluation and design for the construction of the Euclid Wastewater Treatment Plant, an underground 15 million gallon equalization tank and new headworks facility for screening of incoming flow to the plant to remove debris, grit, and grease.

The headworks facility is the first step in the treatment process. Inside the Euclid Wastewater Treatment Plant, debris, grit, and grease will be removed before flow enters the plant for treatment. The 15 million gallon equalization tank will be used during storm events to hold flow until there is capacity within the plant to treat that flow. The area above the equalization tank will be restored to green space after construction.

Our services included mass excavation for tanks and other infrastructure components. We provided geotechnical engineering, slope stability analysis, rock excavation planning, and Temporary Earth Retention System (TERS) design. We performed drilled shaft construction for TERS and monitored soldier pile movement after installation. The excavation area measured 380 X 300 feet, with a depth of 32 feet in high bench area and 58 feet to bottom of main exaction into shale bedrock. The total gross cubic yards of excavation equals 220,000.

In addition to providing geotechnical and design services, our Construction Materials Services (CMS) team provided construction observation during the installation of the TERS. Our Environmental team also provided consulting services regarding UST removal and mitigation of contaminated soils.
