Garfield Well Replacement

Scope of Work

Caliagua served as the prime contractor for Pasadena Water & Power’s Garfield Replacement Well Project, constructing a new groundwater production facility designed to improve local water reliability and replace aging infrastructure. The work included wellhead construction, above-grade mechanical systems, and full system integration with Pasadena’s existing distribution network.

Caliagua’s scope encompassed all civil, structural, and mechanical construction, including installation of the deep-well pump and motor, stainless-steel discharge piping, flow-control assemblies, and surge protection systems. Crews also performed concrete foundation work, site grading, drainage, paving, and perimeter improvements, ensuring the facility’s functionality and long-term durability.

Electrical and instrumentation work—including switchgear installation, SCADA integration, and control wiring under Caliagua’s coordination and quality oversight. The project was delivered in accordance with Pasadena Water & Power’s performance, safety, and commissioning standards.

Community Benefit

Completion of the Garfield Replacement Well provides Pasadena with a more reliable and drought-resilient local water source, reducing the city’s dependence on imported supplies. The new facility enhances groundwater sustainability and operational efficiency through modern automation, improved mechanical systems, and advanced water-quality monitoring.

The project also improves community safety and aesthetics by replacing outdated infrastructure with a secure, well-designed facility that integrates cleanly into its urban surroundings. By managing construction and coordinating specialty trades such as LEED Electrical, Caliagua helped Pasadena Water & Power deliver a high-performing, sustainable water resource project that strengthens the city’s water system and supports its long-term environmental and economic goals.
