Water

Water infrastructure is some of the most critical engineering there is. We provide civil and structural engineering for water sector projects – treatment facilities, pumping stations, reservoirs and network infrastructure – delivering designs that are compliant and built to last.

Engineering for assets that operate around the clock

Water infrastructure has demands that most civil and structural engineering doesn’t. Treatment works that can’t fail, networks that serve thousands of people – when water infrastructure goes wrong, the consequences are severe. Add to that the regulatory oversight from the Environment Agency and Drinking Water Inspectorate that’s more rigorous than almost any other sector, it’s serious.

As water engineering consultants, we design the infrastructure that makes water assets function, understanding the interface between civil and structural design and the mechanical and electrical plant it supports, and we coordinate accordingly. We work with water companies, their framework contractors, specialist contractors and design teams to deliver engineering that meets water industry standards, suits the environment and can be built safely.

Water treatment that works when it matters

When it comes to water and wastewater, there’s no room for guesswork. From municipal sewage to demanding industrial effluent, we design treatment systems that perform day in, day out – meeting discharge standards, protecting the environment and keeping operations moving.

Our work covers the full journey: feasibility, process design, detailed engineering, construction support and operational optimisation. And when industrial wastewater gets complex – fluctuating flows, challenging contaminants, tight consents – we don’t reach for off-the-shelf answers. We develop practical, tailored solutions that fit the site, the sector and the reality of how the plant is run. For manufacturing, food production, chemical processing and beyond, we deliver water treatment engineering that’s robust and built to stand up to scrutiny, from regulators and operators alike.

Engineering on live water assets - without stopping the flow

Most water projects don’t start on a blank site. They happen in the middle of live treatment works, pumping stations feeding active networks and reservoirs that must stay online. There’s no switching it off. Access is tight, services are critical and construction has to work around operational windows – not the other way round.

We design civil and structural works with that reality front and centre. That means phasing around live plant, protecting structural integrity during tie-ins, and making sure new and existing assets interface cleanly and safely. We’re used to working within water company frameworks, AMP programmes, CDM duties and industry specifications – and we understand the coordination and scrutiny that comes with operating assets.

Why Dudleys?

  • Proven experience across wastewater and industrial water infrastructure
  • Practical designs that balance cost, sustainability and operational resilience
  • Confident navigation of regulatory and water industry standards
  • Focus on energy efficiency, resource recovery and long-term performance
  • Close collaboration with clients, contractors and regulators from start to finish

In short, we help improve and expand live water infrastructure without disrupting the very systems it exists to protect.

Frequently asked questions

What does a water or wastewater engineer do?

A water or wastewater engineer designs and coordinates the civil and structural infrastructure that allows treatment and distribution systems to operate safely and reliably. This includes foundations, tanks, drainage, pumping stations, containment systems and structural modifications – all designed to integrate with process equipment and meet strict regulatory standards.

Do you work on live water treatment sites?

Yes. Most of our work takes place on operational assets where treatment processes must continue uninterrupted. We design with phased construction, temporary works and safe tie-ins in mind, ensuring upgrades and expansions can be delivered without compromising service or safety.

Can Dudleys support AMP programme delivery?

Yes. We have experience working within water company frameworks and AMP delivery cycles, designing infrastructure that meets industry standards, CDM requirements and water authority specifications while remaining practical to construct.

Do you design for industrial effluent as well as municipal wastewater?

We do. Alongside municipal treatment works, we support industrial facilities handling complex effluent streams – helping clients manage contaminants, meet discharge consents and protect downstream assets.

How early should engineering be involved in a water project?

As early as possible. Early involvement allows us to understand site constraints, operational limitations and regulatory requirements before layouts and budgets are fixed – reducing redesign, risk and programme pressure later on.

How do you ensure compliance with environmental regulations?

We design in line with relevant UK standards, Environment Agency requirements and water industry specifications. We work closely with environmental consultants and regulators to ensure proposals are technically sound, proportionate and defensible.

Do you provide construction-stage support?

Absolutely. We remain involved during construction to respond to queries, review changes and help resolve site challenges quickly, particularly important on complex or live operational assets.
