What it covers

Tanker services cover the emptying and disposal of septic tanks, cesspits, interceptors, treatment plants and any bulk liquid or semi-liquid waste that a jet vac tanker can safely remove and transport to a licensed disposal point. Every load is documented with a waste transfer note as required by the Environmental Protection Act, since we're a registered waste carrier.

Who it's for

Homeowners on private drainage in rural pockets around Bracknell, Wokingham and the wider Berkshire and Surrey countryside where mains sewerage doesn't reach, landlords with off-mains properties, and commercial sites with forecourt interceptors, car wash drainage or process waste that needs periodic tankering.

When you need it

Septic tanks typically need emptying every 12 months (sooner for smaller tanks or higher occupancy). Cesspits, which have no outlet and simply store waste, need emptying far more frequently — often every 4–8 weeks depending on size and use. Interceptors on forecourts and commercial sites need scheduled cleaning to stay compliant and prevent oil or fuel discharge. Immediately if a tank is overflowing, alarmed, or backing up into the property.

Why professional matters

An overflowing septic tank or cesspit isn't just unpleasant — it's a pollution incident. Discharging untreated sewage to a watercourse or onto land is an offence under the Environmental Permitting Regulations, and an uncontrolled overflow near a private water supply is a genuine public health risk. Getting the emptying schedule right, and using a registered carrier who disposes of the waste properly, keeps you compliant and keeps the system working.

Overflowing Systems Are A Pollution Offence

A septic tank or cesspit that overflows and discharges to land or a watercourse is a breach of environmental regulations, with the property owner liable — not just an unpleasant smell in the garden.

Using An Unregistered Carrier Leaves You Liable

Under duty of care rules, if you pass waste to someone who isn't a registered carrier and they fly-tip or dispose of it illegally, you can still be held liable as the waste's original producer. Always check the carrier's registration.

Neglected Interceptors Fail Silently

A forecourt or commercial interceptor that isn't cleaned on schedule quietly fills with silt and oil until it stops separating anything at all — at which point contaminated water is discharging straight into the surface water drain, and the site is out of compliance.

01

Book The Tankering Visit

Tell us the tank or interceptor type, rough size and access, and we'll confirm a fixed price and arrival window — same-day where the system needs urgent attention.

02

Locate & Access

We locate the tank, cesspit or interceptor cover, open safely and assess condition and fill level before starting to empty.

03

Full Vacuum Emptying

Jet vac tanker draws off the full contents — liquid and settled solids — leaving the tank or interceptor properly emptied, not just skimmed.

04

System Check

For septic tanks and treatment plants, we check baffles, outlet pipework and any mechanical parts are functioning, and flag anything needing repair before waste starts building up again.

05

Compliant Disposal & Paperwork

Waste is transported to a licensed disposal facility and a full waste transfer note is issued in your name, confirming compliant handling under our registered waste carrier licence.

Registered Waste Carrier

Every load is handled and disposed of under our registered waste carrier licence — your duty of care obligation is properly discharged, with paperwork to prove it.

Full Waste Transfer Notes

You get a documented record of every tankering job, which insurers, environmental health and property transactions all expect to see for off-mains drainage.

Same-Day For Emergencies

An overflowing or alarmed system gets a same-day response, not a booking three weeks out.

Right-Sized Scheduling

We calculate an emptying schedule based on your actual tank size and occupancy, rather than a generic annual reminder that leaves cesspits overflowing between visits.

System Health Checks Included

Every emptying visit includes a check of baffles, outlets and mechanical parts on treatment plants — catching small issues before they become a failed system.

Commercial Compliance Support

Scheduled interceptor cleaning keeps forecourts, car washes and processing sites within their trade effluent and environmental permit conditions.

How often does a septic tank need emptying?

+

Typically once every 12 months, though smaller tanks or higher-occupancy households may need it more often. We'll assess your tank size and use and recommend a realistic schedule, not a generic annual reminder.

How often does a cesspit need emptying?

+

Much more often than a septic tank, since a cesspit has no outlet — usually every 4–8 weeks depending on size and occupancy. Ignoring the fill level risks an overflow, which is a pollution offence.

What's the difference between a septic tank and a cesspit?

+

A septic tank treats waste and discharges the treated effluent to a soakaway or watercourse, needing periodic desludging. A cesspit is a sealed tank with no outlet at all, requiring complete emptying every time it fills.

Are you a registered waste carrier?

+

Yes. Every tankering job is carried out and disposed of under our registered waste carrier licence, with a full waste transfer note issued in your name for every load.

How much does septic tank emptying cost?

+

Domestic septic tank emptying typically runs from around £150–£300 depending on tank size and access. Cesspits and larger commercial tanks are quoted based on capacity. All prices are fixed before we start.

What happens if I use an unregistered tanker company?

+

You remain liable under duty-of-care law if that operator disposes of the waste illegally, even though you didn't do it yourself. Always confirm a carrier's registration before booking.

Can you clean commercial interceptors?

+

Yes — forecourt fuel interceptors, car wash silt traps and kitchen interceptors can all be put on a scheduled cleaning contract sized to your site's throughput and compliance requirements.

Do you offer emergency tankering?

+

Yes, 24/7. An overflowing, alarmed or backed-up system gets a same-day or emergency response rather than a standard booking slot.

What if my system is emptied but keeps filling too fast?

+

That usually points to an underlying issue — surface water inflow, a failing baffle or a soakaway that's no longer working — which we'll flag on the visit rather than just emptying it and leaving the cause unresolved.

Are you insured and a registered waste carrier?

+

Yes. Overflow Plumbing & Drainage Ltd carries full public liability and employers' liability insurance and is a registered waste carrier. Certificates and our waste carrier licence are sent across with your quote on request — landlords, letting agents and facilities managers usually want them for their files.
