Battersea is on the public foul sewer (Bazalgette, 1860s) — so a true septic tank is rare in SW11. What the search usually means here is one of three things we tanker on the same fleet: a sealed-tank interceptor at a Battersea Park Road, Northcote Road or Power Station restaurant, a commercial grease trap at New Covent Garden Market or a Power Station food unit, or a sewage-ejector pit beneath the Nine Elms riverside towers. Grease traps £180–£260, sealed interceptors £240–£380, ejector pits £320–£480 — fixed on the phone before dispatch. Section 34 waste transfer note included.
What we do in Battersea
Battersea sits on the south bank of the Thames in the London Borough of Wandsworth, between Chelsea Bridge and Wandsworth Bridge. The postcodes we cover here — SW11 1 and SW11 8 around Battersea Park and the Power Station, SW11 5 and SW11 6 around Clapham Junction and Lavender Hill, SW11 3 and SW11 4 around Battersea High Street and Latchmere, and the SW8 Nine Elms strip — together hold one of the densest commercial-catering and new-build basement-plant footprints in south London. Joseph Bazalgette's southern interception works have carried the foul flow under Battersea since the late 1860s, so traditional buried septic tanks are extremely rare. The work we do here is overwhelmingly trade-effluent interceptors, grease traps and basement sewage-ejector pits — and the search query "septic tank emptying Battersea" usually means one of those three.
Our tanker crews handle 30–45 jobs per month around Battersea. The most common patterns: quarterly grease-trap rotations for the New Covent Garden Market food traders and the Battersea Power Station restaurant units; rolling 6–12 week interceptor contracts for the Northcote Road, Lavender Hill and Battersea Park Road restaurant kitchens; and quarterly sewage-ejector pit pump-outs at the Nine Elms basement plant rooms beneath Embassy Gardens, One Nine Elms and the Prince of Wales Drive riverside blocks. We also run 24/7 emergency overflow response — a sewage-ejector failure beneath a riverside tower is the kind of call we get within 30 minutes of the alarm tripping.
We are a fully licensed waste carrier (CBDU upper-tier registration with the Environment Agency) and all trade effluent goes to a permitted Thames Water disposal site, or to a specialist grease-recovery plant for the market and restaurant food-unit waste. You receive a Section 34 duty-of-care waste transfer note for every job; keep it for at least two years. Wandsworth Council environmental health, Thames Water trade-effluent inspectors, and any conveyancing solicitor handling an SW11 commercial property transfer will routinely ask for the most recent one. Multi-unit New Covent Garden Market and Power Station customers get a monthly visit log that doubles as the audit trail for Food Standards Agency hygiene inspections.

- Why a 'septic tank' search in Battersea matters
- Battersea has drained to the public foul sewer since Bazalgette's southern interception works of the 1860s, so a true buried septic tank is rare here. What the search almost always means in SW11 is one of three things: a sealed-tank interceptor at a Battersea Park Road, Northcote Road or Power Station restaurant that needs scheduled emptying under a Thames Water trade-effluent consent; a grease trap at a New Covent Garden Market food trader or a Power Station food unit; or a sewage-ejector pit in a Nine Elms riverside-tower basement, where the plant room sits below the Thames invert and a single pump failure floods the basement. We tanker all three on the same fleet.
When to call us around Battersea
The six situations below cover roughly 95% of the calls we take from SW11 and SW8 Nine Elms. If yours is not listed, phone anyway — most of the time we can advise on the right service over the call, including whether you need a tanker or a blocked-drain response.
New Covent Garden Market grease trap due
The Nine Elms market traders and on-site catering run grease traps on a 6–12 week rotation under the Thames Water trade-effluent consent. We schedule visits around the overnight wholesale trading window so the tanker never blocks a loading bay.
Battersea Power Station restaurant interceptor
The Power Station food units, Electric Boulevard restaurants and Circus Road West kitchens run sealed-tank interceptors that need quarterly emptying. Service access via the basement loading bays off Circus Road West and Sopwith Way.
Sewage-ejector pit failure in a Nine Elms tower
Embassy Gardens, One Nine Elms and the Prince of Wales Drive riverside blocks run ejector pits because the basement floor sits below the Thames Tideway invert. A pump trip floods the wet well within hours. 24/7 emergency response — call immediately.
Northcote Road / Lavender Hill cafe grease trap
Clapham Junction's Northcote Road, Battersea Rise and Lavender Hill cafe and restaurant strip trips its grease traps on a 4–8 week schedule. We slot visits before the breakfast service to avoid kitchen downtime.
Sewage smell in an SW11 basement plant room
A faint rotten-egg (H2S) smell near an ejector-pit cover usually means the wet-well sludge has crossed the float level. Call before the pump trips. Also worth checking for rising-main hammer noise on the discharge pipe.
Restaurant cellar slow-draining off Battersea Park Road
If sinks and floor gullies in a basement kitchen are all slow at once, the fault is downstream of the trap — usually the interceptor or rising main, not a single blockage. Call before the next service triggers a backflow into the cellar.
How the visit works
Most SW11 grease-trap visits take 25 to 45 minutes from arrival to leaving site. Sealed-tank interceptors take 45–75 minutes. Sewage-ejector wet-well pump-outs take 60–90 minutes including the post-pump-check. The six steps below are what every routine visit looks like.
Call & fixed quote
You phone, describe the property (market unit, restaurant, riverside tower) and access (which service yard, which loading window). We give a fixed price on the call — no callout fee, no central-London access surcharge within the SW11 / SW8 zone.
Same-day dispatch
Routine slots usually within 6 hours during weekdays. Sewage-ejector pit failures and basement overflow emergencies dispatched immediately. New Covent Garden Market jobs scheduled around the overnight trading window.
On-site survey
The driver checks the trap, interceptor or ejector-pit lid, depth and grease/sludge level before the pump starts. Photographs taken for the rolling-contract audit log.
Vacuum extraction
Full empty of the working volume. Typically 25–45 minutes on site for a grease trap; 45–75 minutes for a sealed interceptor; 60–90 minutes for a sewage-ejector wet well plus pump check.
Licensed disposal
Trade effluent and grease taken to a permitted Thames Water disposal site, or to a specialist grease-recovery plant for the market and restaurant food-unit waste.
Section 34 paperwork
You receive the duty-of-care waste transfer note by email the same day. Multi-site customers get a monthly visit log for the audit file.
