Challenge

The Colorado River Municipal Water District (CRMWD) faced a critical challenge: ensuring a reliable water supply during severe drought conditions. With depleted reservoir storage and rising water demands, CRMWD sought to significantly expand its wellfield in Ward County, doubling production capacity to meet current and future needs. The urgency of the project was heightened by the need to have the new groundwater supply operational quickly.

Our Solution

Geo-Logic Associates’ support to CRMWD started with a test drilling investigation to assess subsurface conditions and water quality in the Pecos Valley Aquifer in order to identify optimal locations and depths for new wells. Our team used geophysical methods to characterize the complex aquifer geology and significant variations in total dissolved solids (TDS) and chloride concentrations throughout the wellfield area. The subsequent design and construction phase involved overseeing the construction and testing of 21 new water supply wells.

Our experts developed multi-screen well designs to maximize groundwater production while meeting CRMWD’s specific water quality goals. We conducted thorough aquifer testing to optimize well performance, estimate groundwater sustainability, and inform groundwater model development. In addition to well design, construction oversight, and aquifer characterization, GLA provided pump specifications, equipment procurement support, and integrated the system with the wellfield’s SCADA system.

Results

Through careful planning and fast-track execution, GLA helped CRMWD meet the critical project goals and deadlines. The new wells were completed on time and within budget, and exceeded the groundwater production and water quality targets significantly.
