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

$2 Billion will be used to help finance projects in the state waterplan
EPWU is currently amending the 2011 plan to be eligible for new
state funding

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
