CLE Centralized Deicing Facility
CHA provided final design engineering and construction administration services to the City of Cleveland Department of Port Control for a new Centralized Deicing Facility (CDF) at Cleveland Hopkins International Airport. The project provides apron and taxiway pavement, deicing fluid storage and delivery systems, and spent fluid collection systems.
Significant aspects of this project are described below.
- The CDF is designed for a varying aircraft fleet mix on two separate deicing pads. The main pad design accommodates six Airplane Design Group III (B-737) or smaller aircraft, or three Airplane Design Group IV (B-767) or V (B-747) aircraft. When the Airplane Design Group III or smaller aircraft are using the pad, a second row is provided for queuing.
- A second deicing pad is included for deicing of regional jets to meet the requirements of the hub air carrier. The RJ Pad is capable of deicing three regional jets simultaneously and fluid collection systems are provided.
- Five new taxiways have been added, and one closed runway has been converted to a taxiway in order to provide efficient access and sufficient queuing depth during peak hour departure banks.
- Collection and disposal systems include a segregated 1.6-million-gallon precast underground storage tank below the deicing operator area at the central pad. The tank enables the deicing operator to collect high concentration fluid for recycling, and low concentration fluid for disposal. In the summer months, this reservoir provides storm water detention during a 10-year design storm. Five automated diversion structures are provided to allow storm water to be released during non-deicing season.
- Compliance with strict outfall restrictions is accomplished by use of an impermeable liner under all new pavement and turf areas subject to deicing fluid runoff. Collected fluids are carried by way of a sealed HDPE pipe system to two 2 million-gallon tanks (one which was provided under this project). Disposal is accomplished by a new connection to the sanitary sewer and by a truck upload station. The disposal is monitored and controlled by use of a PLC system.
- Gas, electrical supply, and communications to support a deicing operator control building and administrative facilities.
- Other aspects of the project include pavement design, taxiway edge and centerline lighting systems, modifications to the electrical vault and the computerized lighting control system, NPDES and local permits, bidding and award services, and construction administration.
