Community Drinking Water Systems

For small community drinking water systems, water quality is more than a technical requirement. It is a matter of public trust. Ozone offers a powerful treatment solution for communities that need dependable disinfection, improved water clarity, and better overall water quality without the taste and odour concerns often associated with conventional chemical treatment.

As a strong oxidant, ozone can help reduce microorganisms, oxidize unwanted contaminants, and improve the appearance and freshness of treated water. A typical ozone system includes feed-gas preparation, ozone generation, a contact stage, and ozone destruction, making it a practical and scalable option for properly engineered community systems.

For smaller municipalities and community-scale systems, ozone can be especially attractive where operators want a modern treatment approach that supports both performance and water quality. It can enhance treatment effectiveness, reduce nuisance taste and odour issues, and contribute to cleaner, more appealing drinking water for residents. WHO’s drinking-water guidance is specifically applicable to both large metropolitan systems and small community piped systems, underscoring that smaller systems still need robust treatment and quality control.

Successful use of ozone depends on good system design and proper control. In small drinking water applications, treatment performance relies on factors such as ozone dosage, contact conditions, and overall integration with the rest of the treatment train. EPA guidance for small drinking water systems notes that for UV and ozone treatment technologies, key performance parameters such as ozone dosage are critical to proper operation.

The Numbers;
Ozone demand is calculated from a water analysis, flow rates, contact time, and storage tank size. You can visit our "ozone info center" link in the menu for tools and calculators to determine ozone demand for you project.
Systems need to size tanks based on a 10 minute contact time at 650mV.
This can be controlled and monitored automatically with our ORP controllers, for smaller systems 1-50g/hr the VMC-ORP is suitable, For larger systems, 50+ the RMC Controller is the right choice.
