Civiltec has recently delivered on two different water-related projects for Cahava Springs — a 982-acre, Frank Lloyd Wright-inspired community in Cave Creek, Arizona: a Distribution Pump Station and Reservoir, and a Transmission Booster Pump Station. David Byrum, Chris Dusza, Shem Hawes, David Song, and Andrew Shroads were all involved in the projects. Civiltec coordinated with the Town of Cave Creek, APS, Rural Metro, Cahava Springs Development and the subdivision engineer in order to successfully design the two pump stations.
Civiltec provided the design for a distribution pump station and a 300,000-gallon steel tank for the new community. The distribution pump station, located immediately east of 32nd Street, has three pumps with variable-frequency pump drives. There are two identical distribution pumps sized to meet the Maximum Day Demand (MDD) of the Cahava Springs Development’s 230 dwelling units, and the third pump at the station is a 1,250 gallon-per-minute (GPM) fire pump.
The distribution pump station is connected to the onsite water storage reservoir and has two primary functions:
(1) To provide pressure for the distribution of potable water to the residential properties located within the Cahava Springs Development.
(2) To provide high-demand water to be used for fire protection service.
Civiltec developed a design report, a complete set of plans, specifications, and cost estimates (50%, 90%, and 100%) for this project. The Cahava Springs distribution pump station is equipped with a backup generator, VFD motor controls, mechanical systems, electrical equipment and shade structure.
The transmission pump station is located in the Cave Creek, Arizona, immediately north of Saddle Mountain Road, approximately one quarter mile east of 26th Street and one half mile west of 32nd Street. This station takes suction from the Town of Cave Creek Pressure Zone 1 and boosts water to a new 300,000-gallon tank.
For this project, Civiltec completed a preliminary design report, as well as a full set of plans, specifications, and cost estimates (50%, 90%, and 100%). The transmission booster pump station includes two pumps housed in a shade structure: one pump operates at a time while the other serves as a backup. Civiltec also included “soft start” motor controls, isolation gate valves for suction and discharge piping, “silent type” swing check valves in discharge piping, and pressure and flow sensing and recording instrumentation.
Civiltec teamed with Delta Systems Engineering, Inc. for the planning and design of the transmission pump station’s electrical and controls systems, including a flow meter and a standby generator system with 24-hour fuel storage capacity.
