Wastewater
A 110,000-population works cut treatment energy without new capital plant
Independent monitoring recorded 34% less energy to treat the load, alongside improved nutrient removal, with no new infrastructure required.
The challenge
The deadlines are fixed, the penalties are automatic, and the energy bill keeps rising
Water and wastewater operators are carrying permits they cannot always meet, on plant they cannot easily take offline, under an enforcement regime that no longer waits.
Phosphorus loadings from treated wastewater must fall by half by 31 January 2028, with around 880 works facing tighter consents. Storm overflows must drop to an average of roughly 16 spills per site by 2029. The sector has committed to operational net zero by 2030, twenty years ahead of the statutory target.
Missing any of it is no longer a slow conversation with the regulator. Fines are now automatic and unlimited, and in 2024 reached GBP 104m on a single operator. At the same time energy is the dominant operating cost at a treatment works, with aeration alone accounting for between 45% and 75% of the energy a plant uses.
The conventional answer, a multi-million-pound civil expansion, is the one you can least afford. AMP8 capital is already committed to compliance, and the works still has to keep running while you upgrade it.
Our approach
How we meet the obligation without the capital programme
We improve the performance of the assets you already operate, so they meet tightening consents and carbon targets without new civil infrastructure and without taking the works offline.
Treatment performance, energy use and chemical load are engineered into the process you already run, not bolted on as a new plant. The result is a works that does more, on the same footprint, with lower running cost and a smaller carbon position.
You carry none of the integration. We bring every capability together as a single accountable partner, and every outcome we put forward is backed by a full-scale reference site you can scrutinise before you commit a pound of AMP8 budget.
What you get
Lower cost, less risk, every obligation met
Cost
Take energy out of treatment
Cut the single largest controllable cost at the works. Independent monitoring recorded 34% less energy to treat the load at a 110,000-population plant, with no new infrastructure required.
Cost
Relieve capacity and cut maintenance
Handle more load on the works you already have, with up to around 30% less sludge to deal with and recurring blockages, fats, oils, grease and odour brought under control. Influent and process dependent.
Risk
Bring effluent back into consent
Return an out-of-consent works to compliance without capital works, verified by an independent laboratory and monitored by the environmental regulator. The permit risk comes off your balance sheet.
Obligation
Meet phosphorus and storm-overflow targets
Hit tightening nutrient consents and spill obligations on the assets you run today, so the 2028 and 2030 deadlines are met without a multi-year civil build.
Obligation
Move towards operational net zero
Recover more energy from existing anaerobic digestion, typically 10 to 20% more biogas in field trials, and harness the pressure already in your network, with measurable, reportable carbon reduction towards 2030.
Cost
Reduce chemical dependency
Lower your reliance on dosing chemistry and the cost and scrutiny that come with it, while holding effluent quality where your consent needs it.

The first question every operations and engineering team asks is the right one: is it proven at full scale, and where is the reference site?
So we start there. Every outcome is evidenced at a comparable full-scale works, independently verified, and quantified for your site before you commit. It works around live operations, so the works stays in service, and it is designed to fit your existing WINEP and AMP8 procurement rather than sit outside it. We begin with a single works under pressure, prove the result, then scale.
Every reference and figure is independently verified.
Questions answered
Will this work on a live works without taking it offline?
Yes. The approach is designed to work around live operations, so the works stays in service while performance, energy use and chemical load improve. There is no requirement to take the plant offline or to retrofit new civil infrastructure.
Is it proven at full scale, and independently verified?
Yes. Outcomes are evidenced at comparable full-scale works, including 34% less treatment energy at a 110,000-population plant under independent monitoring, and an out-of-consent works returned to compliance with results verified by an independent laboratory and monitored by the environmental regulator.
Does it require new infrastructure or capital works?
No. Outcomes are delivered by improving the assets you already operate, not by building new plant. That is what lets you meet tightening consents and net zero targets without committing a multi-year civil programme.
Can it help us meet the 2028 phosphorus target and tightening consents?
Yes. The legally binding 50% phosphorus reduction by 31 January 2028, and the tighter consents around 880 works now face, are exactly the obligations the approach is built to meet, on the assets you run today rather than through a capital expansion.
How does it contribute to operational net zero by 2030?
It reduces treatment energy, recovers more energy from existing anaerobic digestion, and lowers chemical use, producing measurable, reportable carbon reductions that count towards the sector's operational net zero 2030 commitment.
Does it fit our AMP8 and WINEP procurement?
Yes. It is designed to fit your existing AMP8 and WINEP frameworks and standards, and to integrate with planned schemes rather than sit outside them, with a single accountable partner carrying the integration.
