This week, ARM welcomed delegates from the International Water Association to Cowdenbeath to visit one of our ARMStorm treatment wetlands.

The site was the first of its kind in the UK and was developed by ARM as a new treatment facility for combined sewer overflows, helping to protect the quality of the receiving water.

Despite challenging site and ground conditions, the project has now been successfully operating for more than a decade, with limited maintenance and no need for refurbishment.

ARM was at the IWA conference in Crete this week, where Andy Freeman presented on 14 years of operating our sludge treatment reedbed at Hanningfield STRB. Since construction finished in 2012, the site has seen reduced costs, streamlined operation, and a big drop in environmental impact.

Wastewater treatment isn't one-size-fits-all.

Every site has different flows, pollutants, space, compliance requirements and future developments - the right wastewater treatment solution starts with understanding the problem, not choosing the technology first.

ARM's bespoke solutions are designed with all of these factors in mind. ensuring your system gives you the treatment you need.

Heavy rain puts real pressure on wastewater systems — reduced contact time, sudden load spikes, and they're becoming more frequent, compounding the problem.

It's also a chance to stress-test your system, allowing you to catch any pooling, flooding or uneven treatment issues early.

An ARMStorm system allows for proactive CSO wastewater treatment, while maintenance and refurbishment can the difference between catching issues early and facing compliance fines.

Reeds may be the most visible part of a reedbed, but much of the treatment happens beneath the surface. Microorganisms in the filter media break down pollutants, while the reeds help create the conditions they need to thrive.

At ARM, we balance plants, microorganisms, media and site-specific conditions to create bespoke wastewater treatment systems for each application.

If your wastewater system isn’t consistently meeting compliance, the problem is unlikely to be down to a single issue. Small gaps in treatment, maintenance or monitoring can gradually develop into bigger problems.

Staying ahead means:

✅ Treating compliance as an ongoing responsibility
✅ Taking a proactive approach to maintenance
✅ Monitoring performance and identifying trends early
✅ Having an incident response plan in place
✅ Reviewing your treatment system when requirements change

The best way to manage compliance issues is to identify them before they become problems.

Working on behalf of Yorkshire Water, ARM has successfully delivered a stormwater management upgrade at Killinghall Wastewater Treatment Works.

As part of a £19 million regional investment scheme, ARM and Mott MacDonald Bentley integrated an ARMStorm side-stream reedbed into the existing site, increasing capacity during heavy rainfall and reducing the risk of CSO events.

Since becoming operational, the system has eliminated reedbed overflows and achieved up to 100% ammonia reduction in most instances, with treated effluent safely returned to the River Nidd.

This ensures:
✅ Reliable performance
✅ Efficient use of available land
✅ Lower lifetime operating costs
✅ Easier maintenance and future refurbishment
✅ Resilience to changes in needs and loads

Your wastewater treatment system may still be operating — but it likely wasn’t built for today’s pressures.

Rising energy costs, tighter environmental standards, and increased rainfall are putting ageing infrastructure under growing strain. While short-term fixes may keep systems running, they often lead to higher costs and reduced resilience over time.

Refurbishment isn’t just about replacing old equipment. It’s about improving performance, reducing operational costs, and preparing treatment systems for today’s challenges.
