Rounds, Waste Notes, and Invoices — One System for UK Cesspit Operators

Yes. Every time you collect liquid waste (cesspit, septic tank, or drainage) you must issue a waste transfer note. The duty comes from section 34 of the Environmental Protection Act 1990, and what the note must contain is set out in regulation 35 of the Waste (England and Wales) Regulations 2011 — the Environmental Protection (Duty of Care) Regulations 1991 were revoked so far as they applied in England and Wales by those 2011 Regulations. The note must include the waste description using the correct EWC code (typically 20 03 04 for septic tank sludge), the waste carrier licence number, and the disposal site details. Defra's digital waste tracking service will require waste receiving sites to record digitally from October 2026 (January 2027 in Northern Ireland and Scotland), and waste carriers (including cesspit operators) from October 2027 — paper carbon-copy pads will eventually no longer be accepted.

The Defra digital waste tracking mandate rolls out in two phases. Phase 1 covers waste receiving sites: from October 2026 in England and Wales, and from January 2027 in Northern Ireland and Scotland. Phase 2 covers waste collectors — carriers, brokers and dealers, including cesspit and tanker operators — from October 2027. Paper waste transfer note pads will no longer satisfy the Duty of Care requirements after the carrier deadline. Operators should register for Defra's digital waste tracking service ahead of the October 2027 carrier deadline.

Most domestic cesspits need emptying every 4 to 8 weeks, depending on the tank capacity and household size. A typical 4,500-litre cesspit serving a 2-person household might last 6-8 weeks, while a larger family could need emptying every 4 weeks. Septic tanks with soakaways generally need emptying less frequently — every 6 to 12 months — because they partially treat the waste. Operators managing recurring customers typically schedule based on property-specific cycle data.

You need an upper tier waste carrier, broker, and dealer registration from the Environment Agency (or equivalent body in Scotland, Wales, or Northern Ireland). Registration costs £191.02 and lasts 3 years. You can check your registration status on the Environment Agency public register. Operating without a valid registration can result in unlimited fines.

The standard European Waste Catalogue code for untreated septic tank sludge is 20 03 04, and that is what it covers — the List of Waste prints it as "septic tank sludge" and nothing more. Cesspool waste is different: a cesspool is a sealed holding tank with no treatment, and the Environment Agency’s RPS 241 and T21 exemption guidance both classify its contents as 16 10 02 (you may still meet the older 20 03 99 at some receiving sites, which the EA is replacing). RPS 231 goes further and conditions reliance on it with "you must not … use the waste code 20 03 04 to describe waste other than untreated septic tank sludge". A mixed load of cesspool and sewage sludge must list both codes. Grease trap waste splits: 19 08 09 covers a grease and oil mixture from oil/water separation containing only edible oil and fats, while anything else falls under 19 08 10*, which is asterisked and therefore hazardous — that needs a consignment note and a disposal site permitted to take it, not a transfer note. Industrial liquid waste may fall under different codes in chapter 16 or 19. Your waste transfer note must include the correct EWC code for every collection — using the wrong code is a compliance violation.

Search the Environment Agency's public register of waste carriers, brokers, and dealers. Enter the company name or registration number. The register shows the carrier's registration tier (upper or lower), expiry date, and registered address. This is freely searchable online. Homeowners should always check before hiring an operator — using an unregistered carrier means the waste producer shares liability if waste is fly-tipped.

Currently, no UK-specific software exists for cesspit and liquid waste tanker operations. Operators either use paper systems, generic field service tools that don't understand emptying cycles or tanker capacity, or nothing at all. The US has multiple purpose-built tools for septic operators, but none are localised for UK compliance (waste transfer notes, EA registration, Duty of Care regulations). PumpRound is being built to fill this gap.

PumpRound is designed to cost less than a single hour of consultant time per month — priced for owner-operators running 1-10 tankers, not enterprise budgets. Join the waitlist to hear about launch pricing first. Waitlist members get priority access and early-bird pricing.

PumpRound is built by Crocker Digital Ltd (Company No. 17008789), a UK-based software company focused on building purpose-built tools for underserved trade verticals. For questions or feedback, email hello@crockerdigital.co.uk.
