2. Objective
To design a water storage tank which improves upon common industry practice in shale Development.  
All of this will be done keeping sustainability and stewardship of the environment in mind.

4. Natural Gas
The gas in the Marcellus shale lies in an unconventional natural gas reservoir.  
This consist of highly impermeable tight limestone and dense shale which can be hard to access.  
Since the gas is difficult to access, unconventional extraction methods such as horizontal drilling and hydraulic fracturing are necessary to extract the gas from the shale

7. Environmental Concerns
Contamination of Drinking Water Aquifers 
Chemicals Used in Fracking Process 
High Water Usage 
Fugitive Methane
Spills and Leaks of Hydraulic Fracking Fluids 
Leaks From Pits Liners and Storage Tanks

8. Project Description - Background
The fracking process requires large amounts of water which must be stored somewhere
Goal: Design an above-ground tank system that has the capacity to store at least 3-million gallons of water on site.

9. Project Description - Common Practice
Conventional Method: Large pits dug and lined
Issues:
Labor Intensive
Liner can only be used once
Liner can leak

10. Project Description - Findings
Large amounts of water are needed to use the hydraulic fracturing process
Large pits or tanks are needed to store this water for use

11. Project Description - Recommendations
Modular Tanks
Can be made to meet any water demand
Only made up of three components
Have rubber seals
Can fit onto bed of tractor trailer

12. Closing
The current method used in water storage is wasteful and could be improved upon.  Modular water tanks are solve the issue of remaking storage units each time a new site is visited. They also require less construction time and materials.
