City Council Regular Meeting

Meeting Date:

03/19/2024

BACKGROUND

The Nacogdoches Water Facility is heavily depended upon during peak water consumption times and emergencies. The configuration of the site is two well pumps, an elevated storage tank and a chlorine injection facility. Currently, the controls and SCADA integration for the site are far past their serviceable lifetime. Many critical components are no longer available, too costly, or only have used options for replacements. The main controller of the site, the Programable Logic Controller (PLC) that automatically maintains the level in the elevated storage tank, communication to the SCADA system and operation of the pumps stopped being sold and supported in 2006. Due to its age, reading its program and making modifications or repairs is costly or impossible. Over time, many of the functions of the site have failed or have been relegated to manual reading and recording of their statuses. Some of these include flow meter readings, motor faults, power failures and chlorine cylinder weights. Communications to and from the site are carried out over a legacy radio system that is also aging, considerably slower and lacks the security that modern options have as standard.

The objective of this SCADA & Controls Upgrade project is to correct the deficiencies in the current system at Nacogdoches Water Facility, improve operational and management efficiency and provide a foundation for future expansion of data collection and control. The proposal from Prime Controls is based off an outline created to account for all necessary functions and data points, including the status of the new automatic transfer switch, generator and future data collection points.

The City solicited Request for Proposals in 2023 for on-call SCADA services and Council approved a contract with Prime Controls in November 2023 with an annual not-to-exceed amount of $100,000.

GOAL

To authorize the City Manager to execute a Contract with Prime Controls, LP for $78,000 and a not to exceed amount of $90,000 for this phase of the SCADA Upgrade Project.

COMMUNITY BENEFIT

Having a modern and reliable SCADA system at the Nacogdoches Water Facility will help provide better service to the city as well as providing a means for efficient operation and management.

SUMMARY OF RECOMMENDED ACTION

Approval of this resolution will allow the execution of the contract for the SCADA Upgrades Project at the Nacogdoches Water Facility.

FISCAL IMPACT

Funding of up to $90,000.00 for the project will come from ARPA Funds identified for the SCADA Upgrades Project.
