State of the Art Water Treatment with Management from the Cloud

The Client

Roxborough Water & Sanitation District (RWSD) serves a fast-growing area located SW of Denver, Colorado, servicing 4,000 customers and treating up to 6 MGD of drinking water.

The Client’s Needs

RWSD was operating a facility originally constructed in 1958 that was no longer structurally repairable, could not keep up with the water demand, and too costly to repair. A new solution was needed, not only to provide high quality drinking water, but also to bring management further in step with the digital future.

The Solution

RWSD selected ACTIFLO®, a high-rate water clarification process, as the heart of the new treatment facility based on its ability to remove over 99% of turbidity, iron, discolorations and the other contaminants from the raw water source.

The new treatment facility is capable of producing 6 MGD per day and the (3) ACTIFLO® units themselves can treat up to 12 MGD. The small process footprint also allowed RWSD to save an estimated 30% on the total installed cost. The new RWSD facility has the distinction of being the first CO drinking water facility to receive 100% of their primary disinfection credits using UV, allowing for a reduction in disinfection by-products.

RWSD’s ability to effectively manage their system is enhanced by the use of the AQUAVISTA™ Portal and Assist platforms, Veolia’s smart water management systems providing greater insight into system performance and access to Veolia’s process expertise with a cloud-based solution.

The Benefits

  • ACTIFLO® saves 30% cost over conventional treatment
  • AQUAVISTA™ allows for proactive management
  • Roxborough gains deeper understanding of their process

Process Description

ACTIFLO® utilizes the combination of coagulation, flocculation and sedimentation using microsand as a seed for floc formation. The microsand provides surface area that enhances flocculation and acts as a ballast to enable rapid settling of coagulated material. 

With AQUAVISTA’s advanced remote monitoring from any web-enabled device, not only does RWSD have more visibility into their plant, but they can tap into the expertise within Veolia to help keep things running smoothly. The AQUAVISTA™ Portal provides a user-friendly dashboard to view and compare process trends, track maintenance tasks, access O&M manuals and maintenance videos and generate customizable reports. With AQUAVISTA™ Assist, a Veolia Process Engineer maximizes the value of such easy access to data and automated reporting by providing regular reviews and recommendations.

Results

The ACTIFLO® system has performed extremely well, with effluent turbidity ready for final filter polishing of < 2.0 NTU and operation and management of the facility has been further enhanced through the AQUAVISTA™ Portal and Assist services. “I like the reports, they are very useful from a management standpoint. I have taken the information provided in the reports and implemented some operational changes and strategies that should help rotate the equipment on a more even basis.” Mike Marcum, Director of Operations.
