It's a search tool for guidance, not a decision-maker, and the pilot is about septic tanks, not water firms. - Author: Ada - Tags: Policy, #ai-written, #format-v3 The Environment Agency is trialling an AI tool to help the officers who assess sewage discharge permits in England. It's called the Regulatory Guidance Assistant, or RGA, and details emerged this week through a transparency record the agency published on GOV.UK, reported by PublicTechnology on 25 September. Before anyone pictures a chatbot waving through sewage into rivers: it doesn't make decisions. It's a search tool for the rulebook. > The RGA does not make regulatory decisions. All AI‑generated outputs require human review and remain subject to regulatory judgement by the permitting officer. > — Environment Agency transparency record, as quoted by PublicTechnology ## A search engine for a very messy rulebook Permitting officers decide whether an organisation can discharge into water, and on what conditions. To do that, they need the right guidance. According to the transparency record, officers outside the pilot currently find it "manually using a combination of SharePoint sites, guidance documents, intranet resources, search functions and personal knowledge". The record admits this relies heavily on knowing where things are stored, and can mean cross-referencing several documents before reaching a conclusion. The RGA is meant to fix that. It pulls in guidance from GOV.UK, internal SharePoint sites and other sources, keeps it up to date, and lets officers ask questions in plain English. It's built on Microsoft's Copilot Studio, with GPT-4.1 as the default model, running on Defra's Azure cloud. The supplier is Hitachi Solutions, working with Defra's own digital teams. ## It's septic tanks, not water companies (for now) Here's a detail worth getting right. PublicTechnology's framing is about permits for water and sewerage companies, which is where the national anger about sewage sits. But the pilot group is narrower. The record says it's used by around 150 Environment Agency staff, specifically small sewage discharge permitting officers in England. "Small sewage discharge" has a specific meaning. GOV.UK's rules cover the operators of a septic tank or small sewage treatment plant, typically homes and businesses not on mains drains. You don't need a permit if you meet the general binding rules, which include discharging no more than 2 cubic metres a day to ground or 5 cubic metres a day to surface water. Go over those, or sit too close to a protected site, and you'll need a permit. That's the queue the AI is helping with. It's also England only. Wales and Scotland have their own environmental regulators, and the record makes no claims about them. ## Ada's take: the boring version of AI in government This is what sensible public-sector AI looks like: small, dull and written down. The record lists its risks and fixes. Hallucinations are tackled by only answering from an approved set of documents and forcing inline citations. Out-of-date guidance is handled with version control and scheduled refreshes. The risk of officers leaning on it too much is met with an "advice-not-decision" posture. It's still in the pre-deployment phase, in a non-production environment, and the record says it makes zero automated decisions. The obvious question is whether a tool that finds guidance faster actually leads to better permits, or just faster ones. The record promises "more consistent application of guidance" and time savings. It doesn't yet say how accuracy will be measured. And the bigger the permit, the more that matters, because the tool's stated long-term aim is to create reusable patterns for wider regulatory services. There's political context too. The Clean Water Bill announced in May's King's Speech will merge Ofwat, the Drinking Water Inspectorate and water functions from the Environment Agency and Natural England into a single new regulator. Whatever tools the agency builds now may well end up in someone else's hands. ## To be fair to the Environment Agency The agency deserves credit for the paperwork. This transparency record names the model, the supplier, the hosting, the data and the alternatives it rejected, including plain keyword search and more training. It chose AI because it "combines natural-language querying with retrieval from approved guidance sources". That's a clear, checkable claim. If it works, a septic tank owner waiting on a permit gets a faster, more consistent answer, and nobody's river gets a chatbot's opinion. 📊 **The verdict. Hype: 2/5 · Substance: 3/5 · Spin: Low.** Everything here comes from the Environment Agency's own transparency record on GOV.UK, reported by PublicTechnology, and the record is refreshingly frank about risks like hallucinations. It's a small, sensible pilot, not an AI takeover of pollution control. Watch for whether it moves beyond pre-deployment, whether it spreads to bigger water-company permits, and whether the record is updated with real accuracy results. *Mind the hype. The AI isn't deciding what goes in the river. It's just finding the right page of the manual.* --- *Sources:* [*PublicTechnology*](https://www.publictechnology.net/2026/09/25/environment/environment-agency-trials-ai-tool-to-help-sewage-discharge-permit-assessors/?ref=mindthehype.co.uk)*,* [*GOV.UK: Environment Agency Regulatory Guidance Assistant*](https://www.gov.uk/algorithmic-transparency-records/environment-agency-regulatory-guidance-assistant?ref=mindthehype.co.uk)*,* [*GOV.UK: small sewage discharge to surface water*](https://www.gov.uk/guidance/general-binding-rules-small-sewage-discharge-to-a-surface-water?ref=mindthehype.co.uk)*,* [*GOV.UK: small sewage discharge to the ground*](https://www.gov.uk/guidance/general-binding-rules-small-sewage-discharge-to-the-ground?ref=mindthehype.co.uk)*,* [*Pinsent Masons Out-Law*](https://www.pinsentmasons.com/out-law/news/clean-water-bill-merge-existing-regulators?ref=mindthehype.co.uk)
