Refuse, recycling and servicing as unit numbers rise

Refuse provision is the quietest reason a residential layout gets sent back. At four houses the collection authority simply takes the bins from the kerb. At forty flats you need a calculated container schedule, a store with ventilation and fire separation, a carry distance that works for residents, and a swept path drawing showing an 11 m freighter getting in and out without reversing the length of the street. Nothing in national policy sets those numbers. The collection authority's own standards do, and they vary between neighbouring councils.

So the first task on any scheme above a handful of units is to find the local waste and recycling guidance, usually published by the collection authority rather than the planning department, and design to it.

How the authority's own standards drive the calculation

Collection authorities publish litres per dwelling per week, or a container allocation per number of dwellings, together with the collection frequency they operate. Those two figures and the number of dwellings give you the storage volume. Everything else is geometry.

The figures differ because the service differs. A council with weekly residual collection needs roughly half the residual storage of one collecting fortnightly. A council operating a four-stream kerbside sort needs more separate containers in less total volume than one taking commingled recycling in a single bin.

Get the standards in writing at the pre-application stage and reference them in the application. An officer reading a design and access statement that quotes the authority's own guidance back at it has far less to argue with than one presented with a store sized by eye.

Container capacity against household numbers

The arithmetic runs in one direction: weekly arisings per dwelling, multiplied by the number of dwellings, multiplied by the collection interval in weeks, divided by the usable capacity of the container, then rounded up with an allowance for imperfect filling.

Two container sizes dominate. Wheeled bins of 240 litres suit houses and small blocks. Eurobins of 1,100 litres suit communal stores, and they need around 1.4 m of depth plus manoeuvring space in front of them.

Where the calculation produces an awkward answer, the common mistakes are these:

• counting the full nominal capacity rather than usable capacity, which ignores lids that must close
• sizing residual waste correctly and then forgetting that recycling, food waste and garden waste all need their own containers
• providing bulky waste space nowhere at all, which is the first thing to appear dumped beside the store
• designing the store to the day after collection rather than the hour before it

Food waste is the one most often missed on flatted schemes. It needs an internal caddy allowance in the kitchen and an external container that is emptied frequently, and a store with no food waste provision will attract a condition requiring one.

Carry distances and collection point positions

Residents should not have to carry waste far, and crews should not have to pull containers far. The code of practice on waste management in buildings, BS 5906, gives the widely used figures: a carry distance for occupants of no more than 30 m to the storage point, and a collection vehicle able to stop within 25 m of the store.

Many authorities tighten that. A pull distance of 10 m on level ground for a wheeled bin, and shorter for a loaded Eurobin, appears in a lot of local guidance, and gradients matter because crews will refuse to pull heavy containers up a slope.

Measure the route, not the straight line. A store 20 m away as the crow flies but 45 m away round a landscaped courtyard fails, and it fails on the drawing rather than at appeal.

Refuse vehicle tracking and turning provision

This is where layouts get redesigned. A standard refuse freighter is around 11 m long and needs roughly 4.5 m of running width with more at bends, and highway authorities generally resist reversing distances beyond about 12 m, following the advice in Manual for Streets.

The evidence the highway officer wants is a swept path analysis on the proposed layout, showing the vehicle entering, collecting and leaving in forward gear, with the turning head dimensioned. Where a private drive serves the scheme, the authority will also ask who maintains it to a standard that keeps taking the vehicle, and a management company obligation is the usual answer.

Shared surfaces and tight radii cause more trouble than overall street width. And tree planting pits positioned without reference to the swept path are a recurring late change, because the arboricultural layout and the tracking drawing are often produced by different people who never compared them.

At the point where unit numbers cross into major development, the servicing evidence usually sits inside a Transport Assessment rather than as a standalone note, and the trigger points for that document change with scheme size.

Communal stores for flats and their ventilation

A communal store is a building, so it needs the things buildings need. Natural or mechanical ventilation to control odour, a washable impervious floor with a drain where the authority asks for one, a water supply for cleaning on larger stores, lighting, and a door wide enough to get a 1,100 litre bin through without a struggle.

Fire separation is the point people underestimate. Bin stores are an ignition risk, and a store built into the undercroft or against the escape route of a block needs the separation and, often, the sprinkler provision that Approved Document B and the fire strategy require. On a building above the higher-risk threshold the fire statement route brings the Building Safety Regulator into the conversation at Gateway One.

Secure access matters too. An unsecured communal store on a street frontage fills with fly-tipped material, and the management regime for keys or fobs should appear in the submission rather than being invented after handover.

Commercial waste where a mixed use is proposed

A ground-floor commercial unit does not share the residential service. Commercial occupiers arrange private collections under a duty of care, and the application has to show separate storage of adequate size with its own access that does not cross the residential store.

Collection times are the live issue. A restaurant whose waste contractor arrives at 6am next to bedroom windows will generate complaints and a condition restricting collection hours, so position the commercial store where the vehicle can reach it away from habitable rooms.

Drawings and schedules that satisfy the officer

Submit four things and the refuse objection usually disappears:

1. A refuse strategy note with the calculation shown, citing the authority's own standards
2. A store plan at 1:50 with containers drawn to size and manoeuvring space dimensioned
3. A site plan with carry routes and distances annotated
4. A swept path drawing for the collection vehicle on the proposed layout

Produce them before the layout is fixed rather than after. Retrofitting a Eurobin store into a consented footprint is the kind of change that needs a section 73 application and costs more than the store.

A Waste Management Strategy drafted on PlanScope sets out the storage calculation, collection arrangements and the authority's standards as separate sections, with the figures left for you to insert from local guidance. Where a scheme is being brought forward in parts, the servicing strategy has to work at each stage rather than only at completion, which is part of the discipline described in phasing a large scheme without gaming thresholds, and the same scale logic drives energy and carbon requirements by scheme size.
