Inflow and infiltration strategies and investigations

Fix the few sources causing most of your inflow and infiltration

When groundwater and stormwater get into your wastewater network, the cost shows up everywhere, in overflows, overloaded pump stations and treatment plants, and lost capacity when it rains. We help you find the sources that actually matter and prove the fix worked.

THE PROBLEM

Chasing every defect rarely solves it

You can measure how much water is getting in, but finding and eliminating the sources is far harder, and there’s no single method that reliably does it.

The usual approach is to hunt down defects and repair them. It sounds right, but it often disappoints. Defects get missed, water finds another way in, and the problem remains after real money has been spent.

How we help

We apply the 80/20 principle, and put the money where the flow actually is.

01

Measure where it’s getting in

We deploy field instrumentation in the parts of your network that overflow or run high in wet weather, and analyse how the flow really behaves.

02

Target the biggest sources

The data shows where the largest volumes are entering, so you investigate and repair the few sources causing most of the problem.

03

Prove the reduction

We redeploy the same instrumentation after the work to measure the flow reduction and show the repairs did their job.

What it means for you

You put investment where it delivers the greatest benefit, and you can demonstrate the result rather than hope for it.

Operating and treatment costs come down, wet-weather performance improves, and your network gets more resilient over time, all from concentrating on the critical few sources instead of chasing everything.
