Slough’s biggest drainage liabilities sit with organisations that manage premises in multiples. Along the Bath Road, Reckitt runs its global headquarters from Turner House, and the corridor’s other multi-storey office blocks keep washrooms on every floor. The town’s retail warehousing lines the same corridor: Slough Retail Park on Twinches Lane and the Bath Road Shopping Park, bought by SEGRO in 2023, both trading from large shared car parks. Four grammar schools, Herschel, Langley, Upton Court and St Bernard’s, admit through one consortium and between them put thousands of pupils through their washrooms daily. And the council’s latest housing strategy counts around 6,500 homes in its own stock. A drainage maintenance contract is how premises on that scale keep their drainage off the reactive list.
Which assets a Slough agreement lists
Take the schools. A secondary school’s list is washroom blocks sized for hundreds of children at once, a catering kitchen with a grease trap, and playground gullies that silt up between terms, and each is written in with its own interval: the washroom branches more often than the stacks, the kitchen line more often than either, the gullies on a date that suits the site, not the calendar. A grammar school admitting through the consortium has the same list as any other secondary; what differs is how many pupils pass through it between bells, and the interval follows that number.
Scheduling around a town that works in shifts
Slough is rarely quiet all at once, which is why the schedule is written asset by asset rather than site by site. Office stacks are worked on before the first badge is swiped or after the last; retail-park car parks are clearest in the hour after dawn; school gullies are done in term, early, before the playground fills. For housing the constraint runs the other way: daytime, so that residents can be warned and a stack is not opened while the flats above it are asleep.
What comes back after every visit
Each attendance produces a dated report with photographs of every asset before and after the work, a note of anything the camera found, and a Waste Transfer Note for any silt or grease taken off the premises. The offices and facilities management page shows how FM teams keep that file.
Costing a Slough site
A Slough proposal applies the published rate to each asset’s visits in a year, totals the lines into an annual or a per-visit price, and puts the result in writing before any signature; the worked example is on the contracts page, and the initial inspection carries no fee. Each visit is insured and guaranteed for 6 months, and one-off yard and car-park clearances in the town are on the commercial drainage in Slough page.
Questions Slough estate managers ask
A unit on our park is changing from retail to a restaurant. Does the contract change too?
Yes, and it should change before the kitchen opens rather than after the first blockage. A food use adds a grease trap to service and a kitchen line that needs jetting several times a year, so the asset list, the intervals and the annual figure are revised together and reissued in writing.
Can routine jetting damage older pipework?
Not when the pressure is matched to the pipe. Jetting runs at up to 4000psi, but nozzle and pressure are chosen for the material and condition of the run, which the annual camera pass reveals. A line with a known defect is cleaned more gently and flagged for repair; cleaning it is still safer than leaving the deposit to block it.
Can gully silt go in the site’s own skip?
Not as general waste. Silt lifted from a gully pot is controlled waste from the moment it leaves the pot, and the occupier’s duty of care follows it off site. Under a contract it leaves with the engineer on a Waste Transfer Note from TrueFlow Ltd, an Upper Tier registered waste carrier, which discharges that duty with nothing for the site to organise.
