Refuse carry distances and bin store design

Refuse carry distance is one of the few dimensional standards that can force a backland or flatted layout to be redrawn, and it is the one most often checked last. Two numbers do most of the work. Occupiers should not have to carry waste more than about 30 metres to the storage point, and the collection crew should not have to drag a container more than about 25 metres from the store to the vehicle. Those figures appear in Approved Document H and in the waste code of practice, and almost every collection authority has adopted a version of them.

Design the collection geometry before you fix the building positions. A scheme that works on every other test can fail on a bin store 40 metres from the nearest point a lorry can reach.

Why carry distance governs the layout

Collection is a pedestrian operation at both ends. A resident walks from a front door to a store, and a loader walks from a vehicle to a container and drags it back. Both legs are constrained, and the constraint is additive with the vehicle's own geometry.

On a conventional street frontage none of this is visible, because bins are presented at the kerb and the distances are trivial. It bites on three layout types: flats with communal stores, backland and mews schemes reached by a private drive, and courtyard developments where the vehicle cannot enter at all.

The usual failure is a store placed where it is least visually intrusive, which is also the furthest point from the adopted highway. An officer will ask for a dimensioned drag route, and the answer will be 38 metres across a landscaped courtyard with a 150 millimetre upstand at the edge.

The distances that appear in standards

Approved Document H addresses solid waste storage for dwellings, and the two distances it works with are familiar to anyone who has read a council's waste guidance. BS 5906, the code of practice for waste management in buildings, sits behind the detail on capacities, store design and vehicle access.

Treat these as the starting point rather than the answer. Collection authorities publish their own standards, and they differ on container types, capacities, separation of stores from habitable windows and whether a vehicle will enter a private road at all. Download the local standard and design to it, because the officer will consult the waste team and the waste team will apply its own document.

Working out the number and size of containers

The method is arithmetic and takes ten minutes, so there is no excuse for an undersized store.

1. Take the authority's published waste generation figure, in litres per dwelling per week, for each stream it collects: residual, dry recycling, food and in some areas garden waste and glass.
2. Multiply by the number of dwellings served by the store.
3. Multiply by the collection interval in weeks, since a fortnightly stream needs two weeks of capacity.
4. Divide by the usable volume of the container the authority supplies, and round up.
5. Add a container where the calculation lands close to a whole number, because a store that is exactly full at collection day is a store that overflows after a bank holiday.

Houses with individual bins are the easy case. Allow the standard storage area per dwelling, keep it within the curtilage, and make sure it is reachable from the front door without going through the house. Flats are where the calculation matters, and where the number of 1100 litre containers often comes out one or two higher than the drawing allows for.

Mixed-use schemes need two stores, because commercial waste is a separate contract with a separate vehicle and a separate collection time. Sharing a store between a ground floor restaurant and twelve flats above is a management failure waiting to happen, and most authorities will refuse it.

Store dimensions, doors and ventilation

Set the store out from the container footprint, not from a notional area. Take the manufacturer's dimensions for the exact container the authority uses, allow clear space in front of each one so that it can be withdrawn without moving its neighbour, and check the diagonal when the container has to turn through the door.

The door is where most stores fail on site. It needs a clear opening wider than the widest container with its lid closed, it needs to open outwards or slide, and it needs a level threshold with no upstand. A 900 millimetre door onto a store full of Eurobins is unusable, and nobody notices until handover.

Then the servicing details:

• High and low level ventilation on opposite walls, so the store does not become an odour source
• A washable floor with a gradient to a drainage point, and a water supply or hose point where the authority asks for one
• Lighting on a sensor, because collections happen before dawn in winter
• Vermin proofing at the base of doors and at ventilation openings
• Separation from habitable windows and from private amenity space, to the distance the authority specifies

Fire deserves a thought. Waste stores are a known ignition source, so keep them out of escape routes and off the external wall beneath escape windows, and coordinate the position with the fire strategy rather than settling it on the site plan alone.

Communal stores for flats

Three recurring problems account for most refusals on flatted schemes.

The first is distance from the furthest core. A single store serving three cores on a long frontage will exceed the 30 metre carry from at least one of them, and the answer is usually two smaller stores rather than one large one.

The second is the level change. Stores in undercroft or semi-basement positions need a ramp at a gradient a loaded Eurobin can be controlled on, and a ramp that satisfies Part M for pedestrians may still be too steep for a 1100 litre container at 500 kilogrammes gross. Where the only route out is a lift, the authority will often refuse, because a lift breakdown stops collection.

The third is presentation. If the authority will not enter the site, the containers have to be brought to a kerbside presentation point on collection day, which requires a hardstanding wide enough to stand the containers clear of the footway, a management arrangement in the lease, and a drag route that satisfies the 25 metre limit from the store. Set the presentation point out on the drawing and dimension it. The same discipline applies to commercial servicing, where standing, reversing and supervision all have to be shown, as set out in the note on servicing yards, standing and reversing.

Getting the collection vehicle in

A refuse collection vehicle is a large rigid lorry, and it needs carriageway width, a turning facility and an approach free of parked cars. Where it will enter the site, provide a swept path analysis using the authority's own vehicle template, show the turning movement at both the entry and the turning head, and check the overhang against kerbs, columns, lighting and trees.

Reversing is the point of contention. National street design guidance treats reversing as something to design out, and most authorities limit it to a short distance where it cannot be avoided. A turning head that works on paper but is routinely blocked by a resident's car is not a turning head, so coordinate it with the parking layout and consider bollards, build-outs or a loading restriction. The dimensional discipline is the same as for accessible bays, covered in the note on accessible parking dimensions, numbers and distances.

Where the vehicle enters a private road, expect the authority to want the construction specification checked, an indemnity, or an agreement that collection will be from the public highway only. Settle that before the layout is fixed.

What to show on the planning drawings

Officers are looking for a small number of specific things, and supplying them unprompted removes a round of correspondence.

1. Store plans and elevations at a readable scale, with the container type and quantity annotated.
2. A capacity schedule showing the calculation, the generation rate used and its source.
3. A site plan with the carry distance from the furthest dwelling and the drag distance to the collection point, both dimensioned.
4. A swept path drawing where the vehicle enters the site, using the authority's vehicle template.
5. Levels and gradients along the drag route, with any ramp dimensioned.
6. The presentation point, where collection is from the highway.

On a minor scheme this material usually sits in the design and access statement and on the site layout drawing. On anything larger the highway authority will expect it in a transport statement, or within the servicing chapter of a transport assessment where the thresholds are met.
