Water Pressure Zone Conversion Projects

Project Overview

As part of its Capital Improvement Program, the Water Resources Department continues to make improvements within its water distribution system. These upgrades enhance water pressure for properties located in project area.

After upgrades are complete, customers within the project area will notice an increase in pounds per square inch (psi). Final water pressures will vary in psi range, depending upon location and elevation.

No water service interruptions should occur during this pressure transition period.

Customers within an active project area will be sent a letter along with FAQs and a map of the affected area.

Customer/Homeowner Responsibility

If you are unsure of your plumbing system's capacity to operate under the increased water pressure or if you have older plumbing on your property, contact a licensed plumber to have your system evaluated. This can identify any needed upgrades, such as installing a pressure-reducing valve (PRV) (left), which may be necessary to control the increased water pressure or avoid other plumbing problems. If you have a PRV installed, it may need a simple adjustment to suit your individual pressure needs.

You are responsible for any evaluation, purchase, installation, and/or repair costs as a result of the water pressure upgrade.

More about Water Pressure Zones

The City is divided into four water-pressure zones. Each zone is influenced by the storage tank elevation serving that zone. Water is supplied to each zone from water pumping stations that pump water from an adjacent lower zone. Water lines are interconnected within each zone to minimize service interruptions and provide a continuous flow of water throughout the zone. The operation of each zone must meet water demand needs in addition to supporting a higher zone as water is pumped from one zone into another.

Customers have different water pressures due to their location relative to the water tank serving them. Low water pressure issues can be due to the high elevation of the area in relation to the tank level serving that zone.

Customers may experience water pressures of approximately 40 pounds per square inch (psi).

Four Farms Water Pressure Conversion Project - December 1, 2025

As part of its Capital Improvement Program, the Water Resources Department is in the process of making improvements to the water distribution system in the Four Farms at Horse Pen Creek Road area on December 1. The upgrades will enhance water pressure for properties in this area.

Once upgrades are complete, customers will notice an increase of 27-37 psi or more in water pressure. No water service interruptions should occur during this pressure transition period.

Customers within this project area have been sent this letter along with these FAQs and this map of the affected area (En Español).

Southeastern Water Pressure Conversion Project - July 27, 2021

As part of its Capital Improvement Program, the Water Resources Department completed the process of making improvements within the southeastern portion of its water distribution system in July 2021. These upgrades enhanced water pressure for properties in this area.

The upgrades increased water pressures to approximately 90 psi to 120 psi, depending upon the location and elevation.

Customers within this project area received this letter (English/Español) along with FAQs and a map of the affected area.

Hilltop Road Area Water Pressure Conversion Project

As part of its Capital Improvement Program (CIP), the Water Resources Department completed improvements in the water distribution system around the Hilltop Road area in 2016. View the project location map. Please note: Only the parcels located in the darker shaded areas with labeled address information were affected by the pressure zone conversion project. The upgrades raised water pressure to approximately 80 psi.
