The factors to be considered in the design of transfer station are as follows:
When a city or entity faces hauling waste “longer” distances, a transfer station may be a viable option. Transfer station costs should be less than the cost of hauling to the landfill directly with collection vehicles (direct haul).
By using a transfer station, collection vehicles spend less time driving to/from the disposal site and more time on the route. Therefore fewer collection vehicles need to be purchased.
A transfer station can be registered if it meets the following criteria:
- Municipality with population < 50,000
- County with population < 85,000
- A facility that transfer < 125 tons per day
- Located within permitted boundaries of Type I or IV landfill
Transfer stations can typically be categorized into several groups such as:
- Open-top
- Surge Pit
- Compactor/Precompactor
- Baler
- Intermodal
Factors affecting the design of the transfer station site include:
- Waste stream demands
- Material types accepted
- Customer types
- Other on-site facilities
- Traffic flow within the transfer station
Design considerations for the transfer building include:
- Wind loading
- Lighting and ventilation
- Sizing and storage
- Expansion capability
- Floor topping
- Green building requirements
Most common equipment used to manage and load waste within transfer stations include:
Wheeled front loaders
- Quicker and more maneuverable than tracked loaders
- Rubber tires produce less wear on the floor
Tracked loaders:
- Better for volume reduction before loading into trailers.
- Tracks cause additional wear on floor surfaces (need to maintain a thin layer of waste on the floor to help reduce wear)
- More common in surge pit transfer stations
The number of personnel used at a station will vary greatly based on the style of the transfer station and the amount of waste processed. Typical positions include:
- Oversight/Administration
- Site Supervisor
- Equipment Operators
- Transfer Drivers
- Scale House Attendants / Cashiers
- Labourers
