The SCADA system is crucial to the security and efficient operation of CRW's water and wastewater facilities. In 2019, the SCADA MP was completed to assess the system and develop a plan for its upgrade, maintenance, and operation. The Town Council approved the SCADA MP on December 17, 2019, which identified approximately $12 million (M) in expenditures over seven years.
In late 2023, the SCADA MP implementation cost was reviewed and updated, revealing a 26% increase in equipment and implementation costs since 2019. Additionally, the update included newly identified work not previously covered in the 2019 scope. As a result, the revised estimated cost for full implementation of the plan in 2023 was approximately $15M. An additional update to the SCADA MP has been completed (2025 SCADA MP). Implementation costs have continued to rise as additional work requirements have been added. Total costs are now estimated at $21M with estimated annual expenditures shown below through 2029.
Budget Impact
Funds have been budgeted each year, through 2029 for the MP Implementation. Funds for this project will be taken from the Water CIP SCADA System Improvements line items as follows:
