Septic Tank Emptying
Regular emptying of domestic and commercial septic tanks across Cornwall. Whoever does it must be a registered waste carrier. Most standard tanks take under an hour.
From £150Full tank in Truro? An independent guide to septic tank emptying in Truro and across TR1, TR2, TR3 and TR4: what it involves, what it typically costs, and how to check a firm is a registered waste carrier. We’re not a septic tank company.
Cornwall's cathedral city sits at the heart of the Duchy, and many properties across TR1–TR4 are well off the mains drainage network. From the city outskirts at Threemilestone, Shortlanesend and Kenwyn out to outlying villages like Probus, Tresillian, Ladock and Chacewater, off-mains drainage is the rule rather than the exception.
A firm that works around Truro needs to know the area's narrow lanes, awkward farm access tracks and where the waste can legally go. Most domestic emptying jobs in and around Truro take under an hour on site, and same-day emptying is sometimes possible if you ring early in the day and a firm has capacity.
Truro itself is largely on mains drainage, so most of the septic work here sits in the ring of villages around it — Probus, Tresillian, Ladock, Chacewater, Shortlanesend and Kenwyn. The lanes out toward Ladock and Tresillian narrow quickly and several properties sit down long private drives, so tanker size and hose reach are the usual deciding factors rather than the job itself.
A lot of the off-mains properties around Truro are converted farm buildings and older cottages, which means tanks of very different ages sitting in the same postcode. It's common to find a 1970s concrete tank on one property and a modern treatment plant next door. Worth knowing before you book: the specialist will want to know roughly what you have, and if you don't know, say so — they'd rather look than guess.
Being central, Truro is one of the easier parts of Cornwall to get a tanker to at short notice — operators are rarely more than half an hour away, and the A390 and A39 give reasonable access in both directions. If you're trying to get emptied the same day, calling before lunchtime materially improves your chances.
We’re an independent guide, not a septic tank company. These are the honest options; pick whichever suits you.
Anyone who takes septic tank waste away must be a registered waste carrier. Whichever local firm you find, look it up on the Environment Agency’s public register before you book.
Ask for the firm’s waste carrier registration and check it, get a written price that says what’s included (disposal, hose length, access), and ask for a waste transfer note once the job is done.
Leave your details and we’ll try to introduce you to one local septic tank firm covering your postcode. We’re still looking for local firms to work with, so we may not have one for your area yet. We’ll tell you who before sharing anything, and septic tank firms may pay us for introductions.
Whatever’s going on below ground at your Truro property, here’s what each job involves and what it typically costs.
Regular emptying of domestic and commercial septic tanks across Cornwall. Whoever does it must be a registered waste carrier. Most standard tanks take under an hour.
From £150Full cesspit pump-outs for sealed systems. Cesspits need emptying far more often than septic tanks, so the running cost adds up.
From £120New septic tank or treatment plant installation, fully compliant with the General Binding Rules 2020. Survey, install, commission: what a full job includes.
From £3,000Tank backing up, soakaway saturated, weird smells in the garden? Diagnosis via CCTV, then repair or replace: how to decide.
From £150 (survey)Blocked or slow-running drains cleared fast using high-pressure jetting. From kitchen sinks to main sewer lines.
From £80Camera inspections to diagnose blockages, root ingress, collapsed pipes, and drainage issues before they become expensive problems. A written report should be part of it.

Septic tank emptying in Truro typically costs between £150 and £300, depending on tank size, access, and how far the specialist needs to travel. Cesspits usually cost more due to larger volumes. Emergency or out-of-hours callouts may incur an additional charge — always get a written quote up front.
Most domestic septic tanks in the Truro area should be emptied every 6 to 12 months. A family of four with a 2,700-litre tank typically needs annual emptying. Smaller tanks, larger households, or heavy holiday-let use can mean more frequent service. Slow drains or odours usually mean it's overdue.
Some local firms can empty a tank the same day when their schedule allows, but it isn’t guaranteed, especially in peak season. Ring two or three firms that work around Truro and say how urgent it is; calling early in the day helps.
You don't need a permit to have your tank emptied, but the waste must be disposed of by a licensed waste carrier registered with the Environment Agency. You can check any firm on the Environment Agency’s public register of waste carriers. Under the General Binding Rules (2020), your tank must also discharge to a drainage field — not directly to a watercourse.
This guide covers Truro and the surrounding villages and hamlets across TR1, TR2, TR3 and TR4, including Threemilestone, Shortlanesend, Kenwyn, Probus, Tresillian, Ladock, Chacewater and St Clement. We’re an independent guide, so we don’t send anyone out ourselves; look for a firm that works your patch and check it on the waste carrier register, or ask us for an introduction.
All waste is transported by licensed tanker to an approved treatment facility or sewage works. Whoever empties your tank must be a registered waste carrier with the Environment Agency, and you can ask for a waste transfer note as proof of legal disposal.
Mostly yes — but some of the terraced streets around the city centre are tight for a full-size tanker. Many firms carry long-reach hoses (up to 50m+), so the vehicle can park on the nearest accessible road while the tank is emptied; ask about hose length when you book. Outlying villages like Probus, Chacewater and Tresillian are rarely a problem.
Most of the city is on mains drainage. The off-mains properties are almost all in the surrounding villages and along the lanes out toward Ladock, Probus and Chacewater — so if you're in central Truro and think you have a septic tank, it's worth confirming before booking anything.
Truro is about as central as Cornwall gets, and most operators covering TR1–TR4 are within half an hour. Same-day emptying is often available if you call in the morning; by mid-afternoon you're usually looking at the next working day.
