About this file
This is a Waste and Recycling Design Guidelines document issued by the District of Columbia Department of General Services (DGS), Sustainability + Energy Division, in support of the Hendley Elementary School modernization project. The guidelines establish standards for waste management infrastructure at DCPS schools, including specifications for disposal containers, dumpster pads, driveways, loading docks, and interior bin placement. For schools with fewer than 500 students, the document recommends Front-End Load (FEL) dumpsters in 6 or 8 cubic yard sizes purchased by the project, while schools exceeding 500 students should consider roll-off compactors or vertical compactors. The guidelines prescribe specific dumpster enclosure designs to accommodate two FEL dumpsters and 2-4 rolling carts with lockable gates, and detail requirements for compactor placement including adequate turning radius and overhead clearance. Interior waste management equipment specifications are provided for various room types, including 7-gallon desk-side bins for classrooms and offices, 23-gallon slim jim containers for common areas, and 32-gallon Brute-style bins with dollies for cafeterias and kitchens, with quantities determined by school size and usage patterns.
The guidelines address critical design considerations including waste flow planning from collection points to exterior disposal, storage requirements for collection bins and bulk trash, loading dock design with water access and drainage compliance, and accessibility principles requiring equal placement of trash and recycling containers to prevent waste stream contamination. The document includes specific case studies from schools such as Langdon Elementary, Mann Elementary, Duke Ellington School of the Arts, Miner Elementary, Dunbar High School, Boone Elementary, and Truesdell Education Campus, highlighting design failures related to inadequate enclosure sizing, poor accessibility, overhead obstacles, and ineffective sorting stations. DGS will provide labels and signage while project teams must determine quantities needed; equipment suppliers referenced include Rubbermaid and Marathon compactor models with specific color specifications (gray for trash compactors and blue for recycling compactors).

DGS/Hauler
DUMPSTER PADS, DRIVEWAYS, AND LOADING DOCKS
Garbage trucks have very limited visibility when backing. Consider a design that provides an area for a truck to turn around or has a separate exit so a truck can pull forward out of the property after servicing a container.
Garbage trucks can weigh up to 65,000 lbs. so dumpster/compactor surfaces need to be able to accommodate this weight load when being serviced.
Be mindful of any overhead clearances. Wires and building overhangs create additional obstacles to servicing dumpsters and compactors.
Two of the biggest challenges for managing waste at schools are illegal dumping (non-school personnel disposing of waste in front of or inside of school dumpsters) and parking (parking in front of dumpsters, blocking access to them). Designs should consider how to prevent these two things from occurring to ensure schools receive regular service.
* Dumpsters are also available in smaller sizes but should only be considered if space is extremely limited ** VIP Compactors are also available in 6yd and 8yd, but they are taller so they should only be used if they are mounted next to a loading dock
FRONT-END LOAD (FEL) DUMPSTERS
FEL dumpsters are a great option for schools with fewer than 500 students. They are easiest for haulers to maintain, repair, and service. Typically, DCPS schools use 6 yd3 and 8 yd3 dumpsters, unless there is need for a smaller dumpster due to space concerns.
Dumpsters can be left in an open space in the parking lot/loading dock area or placed behind a dumpster enclosure. Dumpsters should be far enough apart so that someone can access the side doors to safely place materials inside dumpsters.
The turning radius of a 3-axle truck needs to be considered when mapping out the travel path of a FEL truck to service these dumpsters. The truck needs to approach dumpster straight on in order to fork the dumpster and lift it over the truck to empty the dumpster. Trucks require a high overhead clearance in order to empty dumpsters, so think about potential overhead obstacles such as wires and overhangs when planning dumpster area.
DUMPSTER ENCLOSURES
Design to accommodate two FEL dumpsters and 2-4 rolling carts. Dumpster closures should also include a space to store bulk trash, if possible.
Gates/doors should be lockable. They should swing outwards more than 90 degrees. Doors should also be designed so that they will not accidentally swing inward when trucks or people are servicing dumpsters.
Some DC neighborhoods have specific requirements for dumpster enclosure design.
Langdon Elementary School: This dumpster enclosure is too small for both FEL dumpsters and rolling carts, so it is not been used for its intended purpose.
Mann Elementary School: This dumpster enclosure is too small for side access to dispose of materials. It also has no space for rolling carts or bulk trash. People misuse the rolling carts because they cannot be secured behind the locked gate of the dumpster enclosure.
COMPACTORS
If enrollment is over 500 students, project teams should consider purchasing a set of 15 or 30 yd3 roll-off compactors. 15 yd3 compactors will have enough capacity for the majority of schools.
Compactors are great for areas where pests are a big concern. They are also lockable, so neighbors cannot misuse the compactors. For schools with compactors, compactor training for custodial teams will need to be provided during building turnover.
Roll-off compactors require more room to service than a traditional FEL dumpster. Designs should consider the amount of room needed for a truck to back into the compactor, hook it to the truck, and then pull it onto the truck. They will require the same amount of room to return the compactor to the loading dock after emptying it. Like FEL trucks, roll off trucks require a high overhead clearance to service compactors.
Duke Ellington School of the Arts: The overhang above this loading dock requires that the truck driver drags the compactor out far enough first so that we he begins to lift compactor onto truck it does not hit the overhang. Driver also has to be cautious of the wires hanging above.
If enrollment is near or over 500 students and space is too limited for roll-off compactors or multiple dumpsters, project teams should consider purchasing a set of FEL/REL vertical (VIP) compactors. These compactors, like FEL dumpsters and rolling carts, can be serviced by front-end loader or a rear-end loader.
When purchasing compactors, both compactors should be the same size. The trash compactor should be gray (“Gray 4200-800” from Marathon’s color chart) and the recycling compactor should be blue (“Traffic Blue 4200-307” from Marathon’s color chart).
Project teams should purchase the following models: the roll off compactor Marathon RJ-250SC and the VIP compactor Vert-I-Pack Compactor. See Marathon’s FAQ website for additional specs, such as the concrete pad and circuit breakers necessary for these compactors.
Things to Consider
Flow: Plan for the flow of materials through the building from separation points to outside disposal containers. How can distances that staff must travel to collect and dispose of waste be minimized? Are there obstacles that might disrupt this route, such as stairs, terrain changes, or small doorways? Where will waste be stored once it is collected? Is this interior storage area(s) sufficiently large, well-lit and well-ventilated? Is the storage area at risk of flooding in an extreme weather event? Will the flow of materials interrupt other traffic, such as student pick-up and drop-off?
Miner Elementary School: This sidewalk, where the dumpsters are located, is where most students, parents, and voters (school used as voting location) access building in the mornings and afternoons because it provides direct access to cafeteria where students congregate for before and after school. Having a main building access point that requires walking past dumpster area subjects building occupants to potential smells, pests, and safety risks. In theory, the school could move dumpsters further away from the public entrance way, but there is no downgrade slope built into the sidewalk that would enable heavy cans/carts containing waste to be rolled down to the asphalt area.
Aesthetics vs. Practicality: Built-in waste sorting stations, often installed in school hallways and cafeterias, may look nice but are often not well suited for recycling programs. Some issues associated with sorting stations are that the openings above bins for disposal tend to be too small, too large, or irregularly shaped; the stations are fixed, but the acceptable materials for different waste streams continually change overtime; and the stations create an additional surface for time-constrained maintenance teams to clean and maintain.
Dunbar High School: The waste sorting station installed in cafeteria has holes in the countertops that were too small for cafeteria trays to fit into. School staff uses books to cover the holes to prevent students from using the sorting station. Additionally, the handles and doors are broken, creating additional work for custodial team to complete in order to maintain aesthetics of sorting station.
Accessibility: As a general rule of thumb, trash and recycling cans and dumpsters should be equally accessible in rooms throughout building and in loading docks. The trash and recycling dumpsters/compactors should be equally accessible so that custodial team is not incentivized to use one over the other.
Boone (formerly Orr) Elementary School: This loading dock only has capacity for one dumpster so the recycling dumpster is located on the other side of the parking lot. Recyclables are more likely to end up in trash dumpster because it’s easier and more time-efficient to access. Additionally, this loading dock is tight, so there is not enough room for deliveries and waste disposal to occur at the same time.
Storage: Schools can always use more storage space. For waste disposal, each floor or wing should have a storage closet that can store the round collection bins that are utilized to collect from room-to-room.
Ideally, there should be room in the loading dock garage, the loading dock, or right before the loading dock access door for short-term storage of collection bins, cardboard boxes, and bags of trash. There should also be room for schools to store bulk trash (e.g. broken furniture, construction debris from small projects) because bulk trash cannot be disposed of in normal dumpsters or compactors. Schools need space so they can temporarily store bulk items before they are able to be collected.
Cleaning: Custodial team needs access to a water source and drainage that is compliant with storm water standards in the loading dock in order to clean collection bins, carts, and any messes that may occur during deliveries or waste hauling.
Truesdell Education Campus: A faucet was installed so that a hose can be hooked up in the loading dock. Custodial teams can use this water access for numerous reasons such as cleaning collection bins and any mess that occurs during services of trash dumpsters/compactors.
INSIDE THE BUILDING
The project team should purchase and set up equipment around the school building in accordance with the DCPS recycling program. Use the guides below to determine what supplies are needed for each room and supply specifications for ordering supplies.
