Richfield Water Tower Cleveland Water Department

Cleveland’s Division of Water (CWD) is a major regional utility that supplies water to more than 1.5 million residents in Cuyahoga, Medina, Summit, Geauga, and Lake counties. CWD services approximately 400,000 retail accounts in the City of Cleveland and 63 suburbs. The Cleveland water system consists of nine hydraulic districts covering an area of 620 square miles and includes 5,200 miles of water mains and four major treatment facilities.

Under General Engineering Service Contract X, CWD tasked DLZ with design and construction administration services for an elevated 1 MG spheroid water tank to be constructed in Richfield, Ohio. This over 200-foot tall tower is expected to be the tallest water tower in Ohio. This project, along with a new Booster Pump Station (being designed under a separate project), will deliver on CWD’s strategic expansion and further solidify its supply to Richfield.

Design services on the project include surveying, geotechnical drilling and testing, and detailed design from the civil, process, architectural, structural, mechanical, electrical, and instrumentation disciplines. A mitigation plan developed for the wetland issues discovered soon after the onset of the design phase. A one-and-a-half-acre site adjacent to the one-acre tower site would be available temporarily to facilitate the construction of the tower. DLZ designed detention basins for stormwater from surrounding areas that drain into the tower site and the adjacent temporary construction easement site.

DLZ designed approximately 1,000 feet of access roadway and electrical, water, gas, sewer, and storm system extensions to access the water tower structure from Brecksville Road. The design includes a Stormwater Pollution Prevention Plan, site work and utilities, a water main connecting tank to the transmission main in Brecksville Road, SCADA, instrumentation and controls, electrical systems, and HVAC/plumbing features.

The elevated water storage tank design includes flow metering, altitude valve facilities, a re-chlorination system, tank mixing, cathodic protection, and a protective coating system that meets CWD’s requirements. It also includes an appropriate layout of access features to facilitate operation and maintenance.

The elevated tower is expected to be supported on deep foundations comprising of drilled shafts. Besides the protective coatings and cathodic protection, the tower’s wet surfaces will also be provided with a steel thickness corrosion allowance to ensure long service life.

DLZ is also assisting with securing Storm Water, OEPA, and FAA permits and Zoning/Planning Board approval from the Village of Richfield. The project is currently in its final design phase. DLZ will assist CWD with engineering services during the bidding and construction phases of the project.
