West Jordan Secondary Water Master Plan

Introduction

Hansen, Allen & Luce developed a master plan to provide specific direction to the City of West Jordan for decisions that will be made over the next 5 to 40 years to implement a secondary water system at the most reasonable cost.

Scope

The study evaluated the feasibility of a secondary water system to serve undeveloped, low-density areas, parks, and schools west of 5600 West; existing subdivisions west of 4800 West with “dry” secondary water pipes; and existing parks and schools adjacent to dry-pipe subdivisions. The study identified potential secondary water sources and the infrastructure needed (pipes, storage reservoirs, wells, and pump stations).

Interesting Numbers

  • Estimated Capital Cost: $72.3 million
  • Service Connections: 9,822 (at buildout)
  • Irrigated Acres: 2,586

Project will be the first large-scale use of recycled wastewater in a public water system in Utah.

Challenge

New water resources to support the City are limited and increasingly expensive. West Jordan has long considered developing a seasonal secondary water distribution system to support outdoor irrigation. The system would relieve demand on the culinary water system and reduce the consumption of culinary-quality water. To date, the City only operates a limited secondary water system to irrigate selected parks and open spaces. The City does not have a secondary system to serve residential or commercial areas. The water resources to support such a system, as well as the assoctaed infrastructure, had not been specifically planned.

Solution/Result

The proposed plan addresses the entire secondary water system service area, including dry-pipe subdivisions west of 4800 West and planned low-density and very-low-density residential areas west of 5600 West, along with schools and parks in that area. The system is divided into five main pressure zones and includes five new storage ponds and one existing pond. Six pump stations will lift water from one zone to another. A total of 13 reduced pressure zone (RPZ) connections will deliver culinary water to the secondary system during startup and emergencies. Water will be provided from several sources including the culinary water system (initially), Welby Canal, Steadman Well, Well #1, Well #5, and recycled wastewater from the South Valley Water Reclamation Facility.
