Cotes | Dry-air Solutions for Waterworks

Waterworks play a crucial part in our freshwater infrastructure which is why we have to protect the integrity and productivity of this infrastructure from the harmful effects of unwanted humidity. Explore how we can help reduce your risk and maximise your production output whilst adhering to stringent industry standards.

Humidity Issues in Waterworks

Protect production output and reduce risks

Some of the biggest practical difficulties for those who own and operate modern waterworks facilities are associated with humidity – and the many problems and costs that follow in its wake.

When warmer air containing water moisture comes into contact with cooler fittings and surfaces (such as cold pipework, metal structures and building surfaces), the laws of physics make it condense.

This water then drips, pools and accumulates on and around surfaces, structures, fittings and equipment, which provides an environment highly conducive to corrosion, along with favourable conditions for microbial and bacterial growths to develop and multiply.

Microbial and bacterial growths

Excessive humidity creates favourable conditions for microbial and bacterial growth

Operating and maintenance costs

Excessive humidity is detrimental to equipment and electronics and causes disruption in production output and expensive maintenance costs

Non-compliant hygiene standards

Difficulties in achieving required hygiene standards and poor working conditions for staff

Waterworks humidity issues

What is your dry-air strategy?

The right way to dry your production facility depends on your business needs, objectives, and goals.

Cotes adsorption dehumidifiers come in a range of sizes with varying functions and airflow capacity. Finding the right dry-air solution starts with a conversation. That is why we welcome you to an obligation-free conversation with one of the experts that can help guide you to the right dry-air strategy and the best dry-air solution for you.

Below are some of the humidity issues we see in the waterworks industry.

Let's make a dry-air strategy together

In underground pumping, pumps play a central role. They have a sturdy design and are usually made of robust materials, as these dictate the reliability and durability of the pump. However, at times, even after taking all the precautionary measures, certain unexpected pump failures can still occur:

Corrosion within centrifugal pumps can affect wet surfaces or a small portion of their internal components
Higher service and maintenance costs as a result of uncontrolled humidity
Bacterial growths and mould that result in hygiene and compliance difficulties

Reservoir and Pump Station

Surface water treatment facilities are public drinking water systems that use water from streams, rivers, lakes, or reservoirs to treat the water before it reaches its final destination. Without a controlled-humidity environment, you’ll probably have to deal with:

Condensation and corrosion can damage pipes and structures around the facility
Moisture leads to challenges in hygiene and safety standards
Energy consumption, operating and maintenance costs that are unnecessarily high

It is often a challenge in groundwater treatment to maintain the right relative humidity (RH) level, especially when considering condensation on the surface of the cold pipes and walls. This leads to:

Condensation forming and pooling on pipes, equipment and cold surfaces
Corrosion and other damage to buildings, structures, and equipment
Bacterial growths and mould that result in hygiene and compliance difficulties
Risk of contamination
Higher service and maintenance costs as a result of uncontrolled humidity

A reliable supply of clean drinking water originates through water processing facilities, that when exposed to uncontrolled humidity, will face problems such as:

Condensation on pipes, tanks, building surfaces, fittings and equipment
Undesirable microbial and bacterial growths
Health and safety risks for personnel, due to pooling condensate
Service interruptions resulting from the need for unscheduled maintenance work
Difficulty maintaining hygiene standards

Modern waste water processing requires controlled humidity conditions and effective hygiene management. Without effective dehumidification, such facilities can expect issues that include:

Problems stemming from condensation and corrosion in and around control systems, structures, fittings and equipment
Unreliable and interrupted service to your customers
Unnecessarily high energy consumption, operating costs and maintenance costs
Difficulty achieving required hygiene standards
Health and safety concerns for staff

Cotes have a range of adsorption dehumidifiers for the job. Depending on your dry-air needs, the Cotes team can help you find the right way to dry your waterworks.

Between 2022 and 2025, Cotes gave over 280million litres of fresh drinking water to those that need it the most

CSR

We
give
back

Cotes adsorption dehumidifiers remove hundreds of thousands of litres of unwanted moisture from the air every year from all kinds of industries around the world.

From 2022 to 2025, Cotes gave over 280,000,000 litres of fresh drinking water to those who need it most through a close partnership with UNICEF. In 2026, Cotes will be expanding our partnership collaboration to include communities who need fresh drinking water. We give back, because it is the right thing to do.
