Process water is broadly defined as water used in industry, manufacturing processes, power generation, and similar applications.
Having the required quantity and quality of water to be used throughout the facility is a critical element to ensuring uptime and product consistency.
The specific process water requirements of various industries and plants vary enormously. Process water is usually sourced from surface water, ground water, municipal, or some combination of these water sources. In many cases, the water from these sources needs to be treated to remove contaminants and minerals to protect equipment and ensure a consistent end-product. Water is therefore treated using a variety of process water technologies depending on the feed water, final water quality, and volume requirements.
Veolia is experienced in providing and servicing process water technologies designed to meet these needs, producing high-quality process water from a range of feed water sources and significantly reducing water consumption.

Process Water Uses
Here are just a few examples of industrial process water use:
- Pharmaceutical and cosmetics industries: process water is required that continuously meets stringent regulatory requirements
- Food and beverage industries: flexible water purification and contaminant removal systems support the need for ingredient water
- Chemical and petrochemical industries: process water is used for cooling tower systems, makeup water and blowdown treatment systems
- Automotive industry: vehicle production plants have a significant demand for process water of known quality
