Optimisation modelling

The right solution, in the right place. Every time.

Remove the guess work with data-led recommendations. Use our cutting-edge hydraulic modelling to design rainwater management schemes that deliver real impact.

Too many choices. Too much risk. Not enough certainty.

Water companies want to be innovative - but risk avoidance and cost pressures often stifle new approaches.
And on top of this, are you:

  • Struggling to meet regulatory targets?
  • Unable to compare innovative green solutions with traditional grey infrastructure
  • Drowning in options, but unsure which intervention will deliver the best results?

With thousands of products, approaches, and priorities to juggle - it’s easy to waste time, budget, and effort on the wrong solution.

Unlock innovation with smarter, safer decisions

Remove the guesswork with a data-led, end-to-end approach.

Our high resolution and data-driven runoff modelling identifies the most effective rainwater interventions and optimal location, aligned with scheme objectives - before a single asset is installed.

From the start, we focus on matching the right solution to the right place, helping you design smarter schemes that deliver long-term impact, regulatory confidence, and measurable ROI.

By optimising where and how water is captured, stored, or slowed, we help maximise the volume of water kept out of the drainage system - supporting asset resilience and easing pressure on ageing infrastructure.

What does optimisation modelling deliver?

From maximising efficiency to supporting regulatory compliance - optimisation modelling is an essential first step in any project.

Confidently scale across any catchment and experience multiple benefits.

Boost asset resilience

Reduce pressure on ageing drainage infrastructure by intercepting stormwater before it enters the system.

Maximise impact, minimise waste.

Our modelling ensures every intervention is targeted - increasing the volume of water slowed or stored at the source. We even factor in customer (householder) needs, improving scheme buy-in, adoption and longevity.

Improve ROI

Avoid costly trial-and-error - our approach helps you invest in what works, where it works best

Support regulatory compliance

Design schemes with the confidence they’ll contribute meaningfully to storm overflow reduction and other performance targets.

Make smarter decisions

Data-driven recommendations give your team clarity, consistency, and evidence to justify investment.

Scale with confidence

Whether it’s a single street or an entire region, our approach is built to scale - providing reliable results across multiple catchments or phases.

What can you expect?

More than just insights. Here's what you'll get from us.

Ranked recommendations tailored to your goals

Our modelling delivers a ranked list of interventions designed to maximise impact and fit the specific needs of your project. This includes a cost benefit analysis, to ensure schemes get the most out of every £ spent.

A solution-agnostic approach

We're not tied to any supplier or product. That means our modelling is focused purely on what works - not what needs selling.

End-to-end support

From data input to delivery, our team guides you through the process - helping you interpret the results, validate decisions, and brief delivery partners with confidence.

A foundation for long-term success

Our outputs set your scheme up for smooth implementation, measurable impact, and scalability - giving you a strong base for funding, reporting, and future phases.
