At the turn of the 21st century, the communities of Gilbert and Chandler, Arizona, were growing rapidly, but tight budgets left both working to maintain critical services while attempting to reduce costs. Both needed more water to support their burgeoning communities, and therefore began evaluating water treatment technologies and delivery methods. The municipalities signed a formal agreement to build a shared, $89 million water treatment plant that would serve both communities.
To help them achieve this vision, they selected Sundt as their Construction Manager at Risk. We delivered a state-of-the-art water treatment plant that provides additional water resources for each community, treating raw water from the Central Arizona Project canal, adding redundancy to the existing systems, and supporting sustainability efforts by using a renewable supply in lieu of groundwater.
The team implemented strategies to provide the most long-term value to the two communities. The 24 million-gallon-per-day (MGD) plant was master-planned to ultimately expand to a 48 MGD facility. It features a robust process design and the latest in modern water treatment technology and automation.
By working together, Gilbert and Chandler saved an estimated $22 million in capital investment and $600,000 annually by sharing operational costs of staff, chemicals and electricity.
