2. Presentation Mobile Public Water Systems;
A New Answer to an Old Problem
Presented by: Alan Pyle – Founder and CEO

3. Setting the Table Public Water System Definition:
Transient Non-Community
A public water system that regularly supplies water to at least 25 of the same people at least six months per year.
Below this criteria, no regulatory oversight exists
Above this criteria, the options are:
Water Hauling using the potable water hauling rules
Registered potable water hauling tank
Storage on site, distribution meeting PWS standard
Apply for PWS registration
Source approval (Surface, GUI, Ground Water)
Treatment Process approval
Oversight and management

4. Who Does this Affect?
Locations where a municipal approved source is not available:
Churches
RV parks
Summer camps
Recreational parks
Eco lodge/resorts
Man Camps
Estimated total population in O&G man camps in Texas: >7,000 across 484 sites

5. The O&G Man Camp Dilemma
Technically does not meet the 25/60 rule
Therefore unregulated/No regulatory oversight unless complaint
Move frequencies prevent infrastructure application
Temporary set ups are the standard
Hauling is the chosen solution (in and out)

6. The Problem Water Hauling introduces contamination
Water Storage does NOT meet potable water standards
“NON POTABLE WATER” stickers in houses—says it all
Safety showers connected to non-potable water
Expensive bottled water and ice must be delivered
Raw sewage stored in tanks on site, next to water tanks
Daily truck traffic on site for water deliver/sewage pickup

7. Typical O&G Site Set Up (Oilfield way)

8. The Water Rig Solution
A Self-Contained Proprietary Water Processing System
Multi Step Treatment, Including reverse Osmosis
Complete elimination of bacteria, viruses and spores
A Complete Package
Pressurization to the entire camp via NSF approved piping
Ice Production delivered right at the system
Drinking Water fill station
Easy to Use
We use your well or hauled in water supply
We use the same electrical connection points as the housing
We fully operate and maintain the system
We provide you simple flat rate tickets

9. WaterFleet Monitoring – 24-7-365
Fully Automated Control System
Reliable UL Certified Control System
Allows for Autonomous Operation
Self Monitoring
Remote Monitoring and Control
VPN private connection through site Wi Fi or Hot Spot
Full control and connection via monitoring locations
Automated s from units to monitoring for alarms or shut downs
Data Logging and Reporting
Delivered water quality recorded hourly
Total gallons delivered and recycled recorded
Monthly reports provided to HSE
3rd party bacti lab testing performed and provided

10. WaterFleet Statistics
Over 2,000 samples taken and tested per year for raw water and
product water
14 WF staff dedicated to maintaining compliance
WF processes about 300,000 gallons per day across 125 O&G sites
Equivalent truck trips would be more than 50 per day
From our inception in January 2014, WF has provided approximately
130 million gallons of safe drinking water on drilling sites.

11. The Water Rig; a PWS? Day 1 decision, behave like a PWS; engage TCEQ.
Testing in line with EPA MCL’s and SCL’s
Modeling to determine capability
Data logging and monitoring
Chlorine residuals
Maintain system and distribution network according to best practices
Year 2 decision, inform TCEQ about pad drilling.
More than 25 people
On site longer than 60 days
Non-approved sources
Request and work with TCEQ for a Guidance Document

13. WaterFleet’s Risk Management Approach

14. Abundance of Caution The TCEQ Way
5 Systems approved, but:
60 day operating limit
Ground water only
Corrosivity study
Current Status
Corrosivity study submitted
Wait days for further approval
Expectation to begin approving additional units
Future
GUI and surface water approval
Extensions

15. The Future (is now) MWTS Solutions
Drinking water for large crowd gatherings
Construction
Concerts/Events
Emergencies
Examples
Drinking stations for 100’s or 1,000’s of workers
Emergency man camp - Harvey
Medical Facility – Harvey, storm affected
MMU deployment
Interim water production on new well
