Every commercial kitchen in Slough pours the same thing down its sinks: warm fat that behaves like a liquid right up until it meets a cold pipe. Somewhere between the pot wash and the sewer it sets, coat after coat, until a line that once swallowed a full lunchtime service has narrowed to the width of a hosepipe. TrueFlow provides high-pressure drain jetting across Slough for precisely this problem, serving restaurant kitchens, food production units and canteens as well as the town’s homes.
Grease is a compliance issue, not just a blockage
Few towns in Britain cook at Slough’s scale. The Trading Estate holds more than 600 buildings and a working population of around 20,000, run throughout its history by a single landlord, today called SEGRO, a name abbreviated from Slough Estates Group. Food manufacturers have made confectionery and groceries there for the better part of a century, and every canteen, café and production line in the town discharges into Thames Water’s sewers.
That is where the law takes an interest. Under section 111 of the Water Industry Act 1991 it is a criminal offence to put anything into a public sewer that interferes with the free flow of wastewater, and fat, oil and grease are the textbook culprits. Thames Water’s guidance for food businesses expects active grease management: sink strainers, grease separators or removal units, and licensed collection of waste oil. Jetting belongs alongside those measures, clearing the residue that slips past them before it closes the line and stops you trading.
Planned contracts or the Friday-night call-out
Businesses buy jetting in one of two ways. The reactive way waits for the pot wash to back up mid-service, then pays an emergency rate while the kitchen mops floors and turns covers away. The planned way books us in at intervals matched to how hard your drains work, with fryer-heavy kitchens needing visits more often than an office tea point, timed for the hours you are closed. A maintenance schedule swaps unpredictable crises for a known cost, and gives you dated records of drain condition to show an environmental health officer or a landlord. Where a line keeps fouling, a combined jetting and CCTV survey records what the cleaned pipe actually looks like, so defects can be repaired rather than repeatedly rinsed.
Jetting for Slough homes
Households need jetting for the same underlying reason, at smaller scale. In Slough’s tightly packed terraced streets, several kitchens often share one drain run, so a line can carry three families’ worth of fat and food waste. Thames Water supplies the town with hard water, and the scale it leaves inside older pipes anchors each new layer of fat more firmly than the last.
This is where jetting differs from rodding. A rod driven through congealed fat buys you a channel, and the warm washing-up water that follows keeps it open just long enough to look fixed. A jetting nozzle instead works around the whole circumference of the pipe at up to 4000psi, lifting grease, scale and root growth off the surface and sending the lot on to the sewer, so there is nothing left for the next blockage to build on.
