Presenter

Presentation Notes

Water in the Rio Grande is stored at the Elephant butte reservoir. The water is released during the irrigation season (Feb-Oct)

Presenter

Presentation Notes

This diagram shows the groundwater aquifers used by El Paso Water Utilities. The Mesilla Bolson is shown in yellow. It provides water for the west side of El Paso. The Hueco Bolson is shown in red. It provides water for the northeast and east side of El Paso.

Presentation Notes

EPWU infrastructure is shown in this diagram. The yellow dots in the top left of the diagram are the Mesilla wells that are called the Canutillo Wellfield. The red dots are the wells of the Hueco Bolson. The big white dot at the Central el Paso is the Canal Water treatment plant The white dot in the lower valley is the JRWTP. The light blue dot is the KBH desalination plant.

Presentation Notes

This is a map showing the relative distribution of “Fresh “ and “Brackish” water in the Hueco Bolson. The “Brackish” water is source of water for the Desalination plant.

Presentation Notes

Talk about the process and how it saves money and energy The desalted water is at such a high standard, it is blended with raw water Following the pH adjustment and disinfection, it is sent to the distribution system Concentrate is injected into porous, underground rock through wells Geologic formation prevents contamination of fresh water

Presentation Notes

Why our desalination plant is so unique

Need for Expansion Drought conditions mean shorter irrigation season = less

surface water available for less time KBH is critical when surface water (Rio Grande) is not

available - No surface water in non-irrigation season (winter)- Extends freshwater supply by treating brackish.

In summer, KBH provides peaking capacity to support surface water plants

Proposed expansion of plant to increase capacity from27.5 MGD to 42 MGD

KBH

El Paso Water

Enviro Water Minerals Company (EWM), Public Private Partnership

• Partnership between EPWU and EWM• Construction of a new plant adjacent to existing

desalination plant. • EWM uses EPWU concentrate to recover

minerals.• EPWU receives an additional 2 million gallons

of potable water from EWM.

. 20

Enviro Water Minerals Company (EWM), Public Private Partnership

Enviro Water Minerals Company is using cutting edge technology to recover minerals from waste brine from desalination plants.

21

Enviro Water Minerals Company (EWM)

EWM chemically separates the concentrate

into high-purity industrial grade minerals products that are highly valued in commercial markets.
