  • Water and wastewater systems consisted of aging control systems and equipment.

  • Local support was vital, since many of these problems required driving to the facility.

    • Sometimes this would include late-night program downloads due to power issues and data loss.

  • Plain old telephone systems (POTS) disconnect caused faulted VFDs, and plant generators failing to start. 


  • A phased approach based on system priority was instituted to reduce downtime.

  • This included an emergency retrofit of the water filtration plant’s main control enclosure, control devices, and private cellular network communications.

  • New control strategies to increase operator and system efficiencies.

  • Ongoing improvements to the peripheral sites and water/wastewater facilities.


  • All phases of the project were completed without disruption to the community.

  • Projects were delivered on time and on budget.

  • CSNW has become the integrator of choice to provide SCADA  and support services.
