Project Scope
1,500 to 3,000 gallons-per-minute municipal well
Construction Type
Unit replacements
Project Components
Deep-set line shaft hydrid pumping units, adaptive submersible motor and solid-state soft starters for line shaft hybrid units
The goal of the CRMWA High Capacity, Deep Well, Beta Pumping Unit Replacements project was to improve the reliability and resiliency of the John C. Williams Wellfield. Three “Beta” sites were selected to replace existing problematic pumping units. One site incorporated the use of a submersible motor application, utilizing adaptive technology typically found in mining and petroleum industries. Achieving the necessary horsepower for the project (600 HP) required several submersible motors to be connected in series. The other two Beta sites utilized hybrid line shaft pumping units challenging those industries' upper limits.
Adapting submersible motor technology to municipal wells for this large horsepower size (600+ HP) and production capacity (1,500 to 3,000 gallons per minute) has essentially provided a new application for this type of equipment and an option for engineers to apply in the municipal discipline. Hybrid deep set line shaft pumping units incorporated into this project have basically raised the upper limit of the industry for this type of configuration. This project set a new standard that will further improve with the attrition of other existing pumping units and the construction of new wells.
The project will also have a significant long-term impact on the water supply and the area’s economy. The project assures the 500,000-plus citizens who are served by CRMWA have a reliable source of potable water, despite times of drought. Economically, the solutions developed for this project should yield considerable savings in maintenance costs to CRMWA and its 11 member cities. Sustainable designs and adaptation of technology in this project will play a large role in the continued success of this wellfield.
