Waterworks, pump stations, and sewage treatment plants are environments where moisture is ever-present — and where condensation on cold surfaces causes corrosion, equipment degradation, and hygiene risks that compromise both the facility and the quality of the water it processes. DST desiccant dehumidifiers provide reliable, low-maintenance humidity control for water infrastructure of all sizes — from small municipal pump stations to large filtration halls and sewage treatment plants — protecting critical equipment and maintaining hygiene standards year-round.
Waterworks and pump stations are inherently humid environments. Cold water pipes, tanks, and machinery create permanent cold surfaces that attract condensation whenever the ambient air is warm and moist — particularly in summer, when outdoor humidity is at its highest. Over time, this condensation causes rust on pipework and fittings, corrosion of electrical components, mould growth on surfaces, and deterioration of the structural fabric of the building.
In facilities handling drinking water, humidity management is also a hygiene imperative. Excess moisture creates conditions for bacterial growth — a risk that cannot be tolerated in environments where water quality is paramount. Less than 3% of the Earth’s water is freshwater suitable for human consumption, and every step in its treatment and distribution must meet the highest hygiene standards.
DST sorption dehumidifiers control the dew point of the air inside waterworks buildings, preventing condensation from forming on any cold surface — pipes, tanks, pumps, motors, or structural elements. The result is a drier, cleaner, and more corrosion-resistant environment that requires less maintenance and operates more reliably across every season.
DST dehumidifiers have been installed in waterworks and pump stations across Scandinavia, Central Europe, the UK, Asia, and North America since 1991 — protecting pump rooms, filter halls, pipe galleries, UV filtration stations, and sewage treatment plants. Our systems operate continuously and reliably with minimal intervention, making them well-suited to the unmanned or remotely monitored facilities typical of municipal water infrastructure.
Two DST installations for HSY — the Helsinki metropolitan area’s water and waste management authority — covering waterworks humidity control and pipe gallery dehumidification across separate project phases.
DST supplied dehumidification for Alelyckans vattenverk in Gothenburg — one of Sweden’s largest municipal waterworks facilities — protecting pump rooms and filtration infrastructure from moisture-related deterioration.
DST supplied floating dew point dehumidification for the Leavenworth Water Treatment Plant in Kansas, protecting pump and filtration infrastructure with dynamic humidity control tailored to seasonal temperature variation.
DST has been supplying humidity control solutions for waterworks and pump stations since 1991 — across municipal water utilities, sewage treatment plants, filter halls, and pipe galleries in Sweden, Finland, Norway, Denmark, the UK, Poland, Switzerland, Hong Kong, and North America. All systems are configured to the specific building, equipment, and hygiene requirements of each installation.
