Bin store sizing and collection access in a waste strategy
Bin stores get redesigned at condition stage more often than any other part of a scheme. The arithmetic and the drag distance are what the waste officer checks.
Bin store sizing is arithmetic plus two constraints, and it is worth doing before the ground floor plan is fixed rather than after. The arithmetic takes the number and size of dwellings, applies the council's published litres per dwelling per week for each waste stream, multiplies by the collection interval, and divides by the capacity of the containers the council actually uses. The two constraints are the distance a container can be dragged to the collection point and the route a collection vehicle can take.
Waste officers are consulted on residential schemes and their comments arrive late, often after the layout has been signed off internally. A store that is 30 per cent too small is a design change rather than a detail, which is why this belongs at the same stage as the parking count.
What the strategy must demonstrate
Five things, and a drawing for each where possible.
- Capacity: containers by stream, with the calculation shown.
- Location: the store in relation to every dwelling it serves, with distances.
- Access for residents: level or gently sloping, lit, with a door or gate that opens with a single hand.
- Access for the collection crew: the drag route, its surface and its gradient, and the standing position for the vehicle.
- Servicing: ventilation, a washable floor, drainage to foul, a hose tap, and a cleaning regime.
A Waste Management Strategy covering these five points, with the calculation in a table and the drag route marked on a plan, answers most of what a waste officer asks. Do not confuse it with construction waste planning, which belongs in a Site Waste Management Plan and answers a different condition.
Calculating container capacity from unit numbers
Work in litres, then convert to containers.
The method is straightforward once you have the council's figures. Take the number of dwellings, split by size where the council's rates vary by bedroom count, multiply by the litres per dwelling per week for each stream, multiply by the number of weeks between collections, and divide by the usable capacity of the container. Round up, then add one container of the dominant stream as contingency if space allows.
| Container | Nominal capacity | Where it is used |
|---|---|---|
| 140 litre wheeled bin | 140 l | Individual houses, restricted streams |
| 240 litre wheeled bin | 240 l | Individual houses, the common domestic size |
| 660 litre bin | 660 l | Small blocks, constrained stores |
| 1,100 litre bin | 1,100 l | Blocks of flats, the standard communal container |
Two adjustments matter. Usable capacity is less than nominal capacity, because residents do not compact and lids have to close for collection. And where a scheme has commercial floorspace at ground level, that waste is a separate arrangement with its own containers and its own contract, which cannot share the residential store.
The litres per dwelling figure is the one to source properly. It sits in the council's waste storage guidance, its design guide or its validation list, and using a neighbouring authority's figure is a common cause of a revised drawing. BS 5906 on waste management in buildings is the standard the guidance is usually derived from, and it is worth reading where the council has published nothing.
Recycling and food waste streams
England has moved to a more standardised set of household collections, with separate collection of dry recyclable materials and a weekly food waste collection. The practical consequence for a bin store is that the number of streams is higher than many older schemes were designed for, and food waste needs its own container and its own cleaning arrangement.
Design for at least four streams unless the council confirms otherwise: residual, dry recycling, food waste and garden waste where the scheme has gardens. Glass is sometimes collected separately, which adds a fifth. Confirm the current arrangement with the council's waste team in writing, because collection schemes are being changed and a scheme designed to last thirty years should not be sized against a scheme that changed last year.
Food waste containers are small, heavy and need washing. Allow a dedicated position near the door, a hose tap and a floor gully, rather than treating them as an afterthought at the back.
Drag distance and gradient limits
Two distances govern the layout, and Approved Document H is the usual reference point.
The distance residents carry waste to a communal store is normally kept to about 30 metres. The distance a collection crew drags a container from the store to the vehicle is normally kept to about 25 metres. Where the store is on a different level from the collection point, a ramp rather than a step is required, and a shallow gradient matters more than the horizontal distance because a loaded 1,100 litre container is heavy.
Three details decide whether a crew will actually use the route.
- Surface. A bound surface, not gravel, block paving with wide joints, or grass.
- Kerbs and thresholds. Flush, or with a dropped crossing.
- Gradient. Gentle, commonly quoted as no steeper than about 1 in 12, and consistent rather than stepped.
Where the drag distance cannot be met, the alternative is a collection point closer to the highway with a holding area, and a management arrangement for moving containers out on collection day. Say so explicitly and name who does it, because a strategy that relies on an unnamed caretaker is a strategy the waste officer will query.
Collection vehicle access and tracking
Show the vehicle as well as the road. A swept path drawing using the council's stated refuse vehicle dimensions is the single most useful drawing in a waste strategy.
Four things to demonstrate. That the vehicle can reach the collection point on a route of adequate width and construction. That it can turn without reversing more than the distance the council permits, which is usually short. That there is adequate headroom throughout, including under any archway or podium. And that the standing position does not block the access for other users while collection takes place.
Where the scheme includes a private drive, confirm whether the council will enter unadopted land at all. Many will not, which moves the collection point to the highway boundary and changes the drag distance calculation. Manual for Streets and the council's own highway design guidance set the geometry, and the highway officer and the waste officer need to be looking at the same drawing.
Odour, ventilation and cleaning provision
An enclosed bin store with no ventilation is a complaint waiting to happen, especially with weekly food waste.
Specify cross ventilation at high and low level, a washable impervious floor laid to a fall, a gully connected to foul drainage rather than surface water, a hose tap, lighting on a sensor, and vermin-resistant construction with no gaps under doors. Then state the cleaning frequency and who is responsible, whether that is a managing agent, a caretaker or the residents' management company.
Where the store is within or attached to a building containing dwellings, fire separation is a Building Regulations matter that runs alongside planning, and it affects the construction of the walls and the door.
Drawing the store so it is approved first time
Put everything on one drawing and one table.
The plan should show the store at a readable scale with every container drawn to size and labelled by stream, the door swing, the ventilation, the gully and tap, the drag route marked with its length and gradient, the collection point, and the vehicle standing position. The table should show the calculation from dwelling numbers to container count, with the source of the litres per dwelling figure named.
Then explain the store in the Design and Access Statement rather than leaving it to the technical appendix, because the store's position affects the frontage and a case officer who sees it justified in design terms is less likely to ask for it to be moved.
One honest caveat. Council waste requirements vary more than almost any other local standard, and the figures in one authority's guidance can be half again those of its neighbour. Get the figures in writing from the waste team before finalising the drawing, and record the date you obtained them.

Frequently asked questions
How do I calculate bin store capacity for a block of flats?
Multiply the number of dwellings by the council's litres per dwelling per week for each waste stream, multiply by the weeks between collections, then divide by the usable capacity of the containers the council uses, and round up. Allow for the fact that usable capacity is less than nominal capacity because lids must close, and take the litres figure from the authority's own guidance.
What are the standard communal bin sizes?
The common domestic wheeled bins are 140 and 240 litres, and communal containers are typically 660 and 1,100 litres. Blocks of flats are usually designed around 1,100 litre containers, with 660 litre bins used where the store or the drag route is too tight. Confirm which sizes your council's vehicles are equipped to lift.
How far can a bin be dragged to the collection vehicle?
Approved Document H points to about 25 metres for a collection crew to move a container to the vehicle, and about 30 metres for residents to carry waste to a communal store. The surface, threshold details and gradient matter as much as the distance, and a gradient of around 1 in 12 or shallower is commonly specified for loaded containers.
How many waste streams should a new bin store be designed for?
At least four in most cases: residual, dry recycling, weekly food waste, and garden waste where the dwellings have gardens, with glass sometimes collected separately as a fifth. Collection schemes in England have been standardised and are still changing, so confirm the current arrangement with the council's waste team in writing and record the date.
Will the council collect from a private drive?
Often not. Many authorities will not send a vehicle onto unadopted land, which moves the collection point to the highway boundary and lengthens the drag distance. Establish the position before fixing the layout, and where containers have to be moved out on collection day, name who does it rather than relying on an unidentified caretaker.
