Magna Water District Groundwater Management Program

Magna Water District Groundwater Management Program

HAL assisted Magna Water District with Phase 1 of a Groundwater Management Program to better manage the Barton and Haynes well fields. The study included research and evaluation of historical water quality trends and established prioritized pumping to minimize impact from perchlorate and other water quality challenges. The study also established safe withdrawal rates from the aquifer. Three-dimensional groundwater modeling was used to characterize groundwater flow patterns and predict impacts from pumping alternatives.

Magna Water Company Vulnerability Assessment

Magna Water Company Vulnerability Assessment

HAL performed the Vulnerability Assessment (VA) for all of the Water Company’s water system facilities following the Bioterrorism Act of 2002. The scope of work included assisting with the prioritization of the water system facilities, determination of the Design Basis Threat, evaluation of the consequence for the loss of each facility, evaluation of the effectiveness of the existing protection systems, calculation of the relative risk to each facility, and generation of recommendations to reduce the risk at each facility. Site visits were made to each facility to verify critical assets and existing protection systems.

South Salt Lake Vulnerability Assessment

Spanish Fork Water Master Plan

Spanish Fork Water Master Plan

HAL completed a major update to Spanish Fork City’s Drinking Water Master Plan. Key technical issues included understanding the City’s multi-zone water distribution system, projecting water demands that consider the long-term effects of drought and conservation, developing innovative approaches to pipe network modeling, and updating the City’s GIS-based water infrastructure database.

Freeway Pump Station

Freeway Pump Station

This drinking water project in Draper, Utah, included design and construction of a booster pump station with two 400 horsepower, 1700 gallon-per-minute vertical turbine pumps with pump barrels. The project required geotechnical investigation, hydraulic analysis, transient surge analysis, surge tank design, building design, variable frequency drive design, and a chiller cooling system.

Winder Tank

Winder Tank

For Granger-Hunter Improvement District, HAL provided the design of a 4-million-gallon rectangular reinforced concrete storage tank and an 18-inch-diameter inlet/outlet pipeline. The project included permitting, site surveying, geotechnical evaluation, and design of the reservoir, valve vault, piping, and overflow pipeline. It also included electrical design and construction, tying into GHID’s existing SCADA system, and preparing a detailed landscape and irrigation plan to meet local requirements.
