Pilot Program

The Company

WaterStop Carts is a socially responsible, for-profit company based on the simple proposition that people around the world need safe, accessible and affordable water sources. We seek to address the discrepancy between demand and access and have created a new mobile delivery system that filters tap water for contaminates as well as impurities and gives it the same taste as bottled water. We like to say, “It’s like bottled water without the bottle.” Our cart’s filtration system also filters water that has been desalinated, reclaimed or recycled. With the urbanization of the world’s population and the aging and decaying of our water infrastructure, WaterStop Cart’s mobility plays an important role in making clean water available to people in cities and in developing countries around the world.

Our water sources needs to be clean and mobile for the health of humanity and accessible in all locations were people gather. Bottled Water companies have filled the void of accessibility by creating a solution that is not environmentally sustainable. Accessibility through Mobilityis the foundation of our thinking.

Bottled water costs 2000 times the cost of a gallon of tap water. Our mobile refill stations will save families, businesses and governments the extraordinary amount of money spent daily on purchasing bottled water (the US spent $11.7 billion in 2013). Equally important, our carts will save water currently wasted in the manufacturing and distribution of bottled water. Carts will help eliminate the daily 60 million plastic bottles (50 billion a year) that go into our landfills and oceans from the U.S. alone. The cart’s 50 gallon tank equals approximately 400 16 oz bottles, a savings of 100 gallons of water per tank refill; this does not include the financial and environmental costs of recycling.

  • 70% of the World’s Population will live in Urban Environments by 2020.
  • With the aging and decaying of our water infrastructure the cost of replacing pipes could reach more than $3.6 Trillion by 2020
  • Estimated 240,000 water main breaks per year in the United States alone.

The EPA has found 5,300 water systems in the U.S. that have high levels of lead in its water, affecting 18 million people. Once we have completed the Pilot Program in US Public Schools, we will have the metrics to apply for carbon credits to sell trade or offer to cart sponsors as we roll out the Nationwide Program for our mobile refill stations at:

  • Sports Venues
  • Educational Institutions
  • Entertainment venues like Disneyland, Legoland etc.
  • Concerts, Street Fairs, Farmers Markets
  • National and Local Parks, Golf Courses
  • Hotels and Conference Centers
  • Retail, City, County and Federal Office Complexes
  • Military Compounds
  • Transportation Hubs like Airports, Train Stations, and Bus Stations
  • Food Vendors, Gas Stations, Bodegas, Tourist spots
  • Crisis Management organizations like FEMA and the Red Cross – for these emergency services, carts can also be used to distribute antibiotics and food nutrients


The Pilot

Video of first Prototype at: https://vimeo.com/66376983

Version 2.0 for the Pilot will include Wifi and an LCD

  • We expect to begin the pilot either Winter Semester 2017 or Spring Semester 2018,
  • Financial stipend for the person who is responsible for oversight and maintenance of the cart.
  • Cart will belong to school after pilot program.
  •  Sponsorship will be announced on digital banner for one year and/or announcements on the LCD for a year.
  •  The responsible person will interact with a WaterStop or Sigma Design representative

Most things we need to learn, e.g., user perception, user ability to perform the operational tasks required, we will have collected data for in the first 45 days after deployment. These items include:

  • Evaluating the in-field training usefulness and the systems ease of use
  • Demonstrate the effectiveness of the system
  • Demonstrate the effectiveness of our remote use battery and its charging cycle and life tests
  • We will observe the user and how they operate the system to learn from this and find updates for future systems
  • Observe the users and maintenance staffs use at numerous functions: sports venues, cafeteria, outdoor gathering spots on campuses etc. A stipend will be provided to the personnel who oversee the maintenance of the cart for the duration of the pilot
  • We will ask food service or janitorial staff to replace the UV and the filter cartridges
  • We will review the semi-annual water tank sanitation process for internal water component – fundamentally we need them to perform the semi-annual recommended maintenance on site
  • We will obtain (by observation) user feedback on the operational aspects of the system
  • Proof of Concept for a national/global program for advertisers and sponsors
  • Document savings both financially and environmentally
  • Document the metrics needed for application of Carbon Credits
  • Ease of mobility and placement of carts, we begin this focus at sports facilities like gyms, stadiums, sports fields with access for all visitors, families and friends at student athletic competitions. Placement will vary according to location of student population
  • Carts are locked in place and do not require being manned – the cart sends out signals to personnel on low battery or the need of a tank refill


Technical aspects include:

  • Measure the extension of Wifi around the cart
  • Create and test the use of Media Center for LCD,
  • Generic websites for schools to include YouTube like channel for student videos
  • Content slides – gather available free slides on slides sustainability, social issues etc.
  • Create and test online manuals for cart maintenance and other issues
  • Changing messages on the digital banners
  • Use of water testing kits
  • When and how to change filters (filter changes after 2,500 gallons)
