Apples vs. Oranges
Why USFOS/Killam Water are In-Close for Water
* Sustainability of Far Northwest Webb/Dimmit Co. Water is absolutely questionable
* Pumping test and modeling of Northwest Aquifers will confirm lack of sustainability
* If such NW water is used, it will have a near-term negative impact on others wells
* NW Water has a high likelihood of causing mixing and pipe scaling problems
* Investment in NW Water/system is risky and will ultimately require R. O. Treatment
Advantages of USFOs/Killam In-Close Water
* Shortest distance to convey water for City use
o Even though known to be Brackish
* Requires dealing with the fewest landowners
o Expedites and simplifies water delivery to the city
* Most likely quantities of water
o Allows for a yield of 20-MGD along optimal production line
* Most likely capable of providing sustainability
o Can meet 100 year City Objective
* Very low likelihood of producing Major Negative Impact on current and future wells
* Fracture traces are everywhere
o Pumping tests will confirm benefits
* Location and availability of treatable water
o Can serve Aquifer storage and recovery strategies.
How we access water in phases
* Wellfield in well pairs to 60
o 5-MGD to 20-MGD
* Collection and Conveyance
o Deliver water for treatment
o Go from 5-MGD to 20-MGD
* Typical well pairs site
Summary of preliminary costs per 1,000 gallons
Capacity Source Cost/1,000 gal.
Base - 5-MGD Laredo/Carrizo $ 2.03
Alternative 5-MGD Laredo/Queens City $ 1.96
Base - 7.5 MGD Laredo/Carrizo $ 1.98
Alternative - 7.5 MGD Laredo/Queens City $ 1.91
Base - 20-MGD Laredo/Carrizo $ 2.00
Alternative - 20-MGD Laredo/Queens City $ 1.96
* Does not include the Cost of Water or Right-of-Way.
Why our prices are realistic
* Treatment costs are dramatically lower than CH2Mhill's Estimates
o Ours = $1.91/1,000 gallons
o CH2Mhill's Study = $3.07/1,000 gallons
* Water wells are 12-inch bores and based on quotes friom experienced drillers
o Ours = $343,300
* Line Costs are based on most recent material and construction costs
* Ours = $66/Foot - Including pipeline and construction costs
* Strict Adherence to sizing pipes
* Keep conveyance losses to 2.5 feet of loss per 1,000 feet of line
* Example: A 51 mile conveyance line with no water treatment and no wells would
put water at $1.32
* Total treatment and disposal costs for reverse osmosis = $1.91/1000 gallons
* Laredo area Brine Water at 2,500 ppm
* Ours = $0.75/1,000 gallons
* CH2Mhill Study = $1.67/1,000 gallons
