Why was the PSB created in 1952?What happened in 1951?

March 2 Reclamation Bureau Cuts E.P. Water Supply

March 9 Water Rationing in the City for the Summer

March 11 Serious Water Shortage Faces City

June 1 Power Firm Fears Water Shortage

June 10 Independent Water Board Suggested

June 23 River Drop Leaves Areas Waterless

Why was the PSB created in 1952?

At that time the 1950 1952 was the drought ofrecord

There was intermittent surface water and entire areasin the central part of town were out of water

Additional well drilling failed to add appreciablesupplies needed greater distance between wells soland was purchased

Needed long term planning

EPWU obtains surface water allocations from the El PasoCounty Water Improvement District #1

EPWU currently has an allocation of 70,000 acre-feetbased on a full release

Due to treatment capacity limitations and the pattern ofdemands, EPWU can use about 60,000 acre-feet per yearin a full allotment year

The JRWTP expansion currently under design wouldexpand the plant from 60 MGD to 80 MGD thus providingcapacity to use 75,000 acre-feet

Early in irrigation season (with full allotment), excesssurface water capacity used for aquifer recharge

Allows EPWU to fully utilize its surface water rights

Up to 5,000 acre-feet of aquifer recharge available per year

using recharge basins in Northeast El Paso

Effective management of groundwater resources bybanking excess surface water which will be used duringfuture drought conditions

Drill and equip of up to 10 shallow brackish wells within a 2mile radius of the Jonathan Rogers plant

This will develop an additional production capacity of 10MGD

Would require a reverse osmosis plant at the Rogers plant

Concentrate disposal through deep well injection

Step one would be to identify and permit the injection well

Lower Valley Brackish Groundwater

Currently studying the potential for increasing the capacity ofthe KBH plant

Add 6th skid, additional source wells and concentrate disposal

facilities

Possible adding a drought mode of operation with a higherfinished water salt content

Salinity of these wells has increased over time and they arenow quite brackish

Agricultural Drain Purification

Agricultural drain water in any season is of lowerquality (higher salt content) than river waterduring the irrigation season

The concept is to take water out of the drain inthe non-irrigation season to make drinking water

This can be implemented quickly to provide an

additional 2,700 acre-feet annually

Additional Conservation

The Region E plan calls for conservation to dropper capita consumption from 130 to 118 by theyear 2060

We need to first gauge whether it is possible to

reach 118

We then need to develop a program to providemethodical reductions over time to reach the goalif needed

Alternately, additional sources of supply must beobtained
