City of Soledad Water Master Plan

Preparing a Master Water Plan for Future Growth

The City of Soledad's water master plan serves as the basis for planning and budgeting of capital improvements to meet residential and commercial customer demand and ensure infrastructure capacity for future growth.

Building on a water system evaluation Harris & Associates prepared for the City in 2015, as well as maintenance initiatives associated with the City’s water wells and storage tanks, Harris completed a water master plan in 2019.

The project comprised a water system assessment and updated water demand projections through to build-out of the City limits. It established design criteria to be used as a baseline for evaluating water supply and distribution sufficiency and created a roadmap for efficient utilization of groundwater resources to meet future demand.

Core Elements

Key components of the project included building an accurate and calibrated model of the distribution system using Bentley WaterGEMS to assist with the hydraulic analysis. The model simulated hydraulic conditions defined by the design criteria to identify any modifications needed under existing and build-out conditions.

Harris also proposed a Capital Improvement Program to mitigate hydraulic deficiencies, prioritizing them by urgency and projected ROI.

Beyond the Blueprints

Harris has provided engineering support to the City for several years to help it efficiently address diverse infrastructure challenges. That experience and familiarity with the City’s water system, growth horizon, and development challenges helped ensure the success of the project and the value of the resulting water master plan.
