Capital Improvement Planning
Garver assisted one of the largest and most complex water and wastewater systems in Arkansas to ensure safe and reliable service to its customers. The system includes over 1,000 miles of pipe that would stretch from Springdale to Winnipeg, Canada, several pump stations and tanks with five pressure planes, and 26 lift stations. The 5- and 20-year planning horizons have capital improvement needs of $68 million and $168 million, respectively.
"We're establishing working, calibrated water and wastewater hydraulic models integrated with GIS for master planning evaluations herein, subsequent utilities staff evaluations for improvements and development, and subsequent master plan updates on a 5-year basis," said Project Manager Chris Buntin. "The result will be prioritized capital improvements to reduce operating costs with respect to potable water loss and infiltration to the wastewater collection system."
Based upon population projections, discussions with several stakeholders, and future land-use plans, the average daily water demand at SWU is estimated at approximately 18 million gallons per day (MGD) and approximately 32 MGD for 2020 and 2040, respectively. Future average daily flows to the SWU Wastewater Treatment Facility are estimated at 15 million gallons and 29 million gallons for 2020 and 2040, respectively. The Treatment Facility has a design capacity of 24 MGD.
"SWU proactively manages existing water and sewer facilities to accommodate continued growth as cost effectively as possible," said Project Manager Chris Buntin.
"Garver's level of professionalism and quality of report meet all expectations," said Rick Pulvirenti, SWU chief operating officer and director of engineering.
Garver helped the Springdale Water Utilities, one of the largest and complex water and wastewater systems in Arkansas, improve a system that includes over 1,000 miles of pipe, several pump stations, tanks with five pressure plans, and 26 lift stations. By establishing working, calibrated water and wastewater hydraulic models integrated with GIS for master planning evaluations, subsequent utilities staff evaluations for improvements and development, and subsequent master plan updates to prioritize capital improvements, Garver helped the utility reduce operating cost with respect to potable water loss and infiltration to the wastewater collection system. Based on population projections and other factors, the average daily water demand at the Springdale Water Utilities is estimated at approximately 18 million gallons per day (MGD) by 2020, and 32 MGD by 2040.
