Cleveland Division of Water - GIS Hydraulic Model

Cleveland Department of Public Utilities, Division of Water

Cleveland, Ohio

A hydraulic model of the existing and future service areas was created and linked to a water quality model and surge model.  RTC’s role included preparing projections of system demands for the year 2020 within the existing Cleveland Water service area as well as in the surrounding communities that may be added to the system.  The demand analysis includes Cuyahoga County and nearby communities in Summit, Medina, Geauga, and Portage Counties.

RTC gathered data from the Ohio Department of Development as well as County Planning Commissions, local chambers of commerce and business development agencies regarding land use, zoning, master plans, and commercial/industrial development.  Data was translated to the population projection zone level GIS layer. 

• Demands were assigned to hydraulic model nodes within the zones for each pressure district. 
• Demands for communities that may join the water system in the future were projected by estimating future conditions and developing nodal demands similar to the existing system. 
• Demands per node are also to be available on the GIS and can be updated at any time to reflect new conditions/factors.

RTC created a database linked to the appropriate entity in the Mini-GIS using as-built drawings of system water lines and facilities information that include:  Location, Material Type, Date of Installation, Internal Liner Conditions, Pump stations and pump curves, Surge tanks, Regulators, and Storage Facilities. Additionally, RTC provided a three-month training program of CWD staff in the implementation and maintenance of the Mini-GIS.
