Humidity control for water and wastewater treatment facilities
Protecting pipes and operations in waterworks and sewage plants
Water and wastewater treatment facilities are the backbone of community infrastructure. From large regional plants to small remote pump stations, these sites face a constant battle against humidity. During the warmer, more humid periods of the year, many facilities experience unplanned production stops caused by excessive humidity.
The problem lies in unavoidable temperature differences. When warmer moist air meets cold surfaces on pipes, valves, and storage tanks, condensation forms.This condensation corrodes metal, damages electrical systems, encourages mold growth, and disrupts operations.
With an effective dehumidification solution, you avoid costly unplanned process stops, electrical malfunctions, and unhealthy working conditions.
Without effective dehumidification, you risk:
- Corrosion on water pipes, tanks, valves and structural steel
- Electronics malfunctioning and short circuits due to moisture
- Mold and bacteria, resulting in odors and unpleasant working conditions
- Unplanned downtime
“We have a completely different climate in our buildings, much fresher and corrosion has stopped. Also, our alarm devices are no longer affected by the moisture. The investment has paid for itself in less than a year. We are very satisfied!”

How humidity impacts water and wastewater facilities
Water in piping is usually colder than the ambient air, making water treatment plants susceptible to condensation. Seasonal changes can amplify the problem, especially during warmer periods of the year. This year-round exposure means that facilities should always have a humidity control strategy.
Benefits of industrial dehumidifiers in water treatment facilities
Effective humidity control is essential for any water treatment or sewage plants to keep operations running smoothly, avoid electrical malfunctions, costly unplanned downtime, and to maintainsafe working conditions.
Munters’ energy-efficient dehumidifiers feature rugged construction suited to harsh environments, are designed to prevent corrosion, deliver precise humidity control, and minimize required maintenance. All systems feature real-time monitoring of humidity and temperature, providing floating dew point control at maximum energy efficiency.
For added peace of mind, Munters’ dehumidifiers can be equipped with Munters AirC Connect for remote control. This cloud-based solution makes it possible to monitor, adjust settings and get alarm notifications on your mobile phone or desktop computer.
Why dehumidification outperforms heating alone
Heating air to lower relative humidity doesn’t lower the dew point, which is the point at which air becomes saturated with water vapor. The absolute humidity - the actual water content - remains unchanged. Once the temperature drops, the relative humidity rises again, and condensation returns.
Dehumidification on the other hand, will eliminate the source of the problem:
- Moisture removal at the source instead of masking the problem
- Dew point control to stop condensation on cold surfaces
- Energy efficient, compared to heating and other methods
- Stable relative humidity at optimal levels year round, both in warm and cool climates
