Technology Used:
In response to the observed need, BOR has designed and built a working prototype of the FullStop(TM) water tap for potable systems in developing countries with the following attributes:
1. Hygienic - user hands have no dry contract with mechanism
2. Self-cleaning - water runing thru/over unit provides continuous rinsing
3. Water Saving - self-closing design prevents waste when not in use
4. Sustainable - simple design, one moving part, rugged and easy to repair
5. Low Cost - injection molded plastic parts, standard thread size
6. Goat-proof - design minimizes potential damage by unintended users and vandals.
7. For Gravity-Fed, Low Pressure Systems - unlike First World taps ment for use with pressurized inflow, FullStop is designed to operate with low hydrostatic head gravity systems such as RWH storage tanks,
A flexible plunger opens the valve when slight upward pressue is applied by hands (when washing) or water bottle (when filling) and seals when pressure is removed. The plunger remains in the water stream when in use and is continuosly rinsed with clean water. All parts are injection molded and the plunger can be made with small amounts of powdered silver in the plastic mix, proven to inhibit bacterial growth.
The FullStop(TM) water taps will be manufactured by the injection molding process from a food-grade material, i.e. polyethylene plastic or an alternative recyclable material, UV inhibitors can be added to the molding compound to reduce degradation due to sunlight exposure, and Ag or other non-toxic bacterial inhibitor can be added to aid hygiene. The elegant design and injection molding process will enable the molded taps to be produced far below the cost of conventional taps, with a goal = final cost USD 2/unit.
Phases:
Multiple Phases over a 3 year period
Community Organization:
BOR is a member of the Peer Water Exchange (PWX) and we envision some of the other 91 member non-profit organizations to participate in the refinement of the FullStop(TM) taps by utilizing them in their water projects. BOR is responsible for the design, prototype funding, manufacture, marketing and distribution. PWX members will be pivotal in monitoring on-site tests of initial run units, as well as distribution. PWX members will be depended upon to assist with identifying distribution partners in developing countries; both local NGO's and government agencies. PWX has a peer review mechanism which has proven an effictive way for ideas to get into the field and provides business intelligence tools to keep track of projects and their operating status. PWX is a central point of connection between organizations conducting field programs throughout the developing world and is therefore an ideal vehicle to spread ideas and concepts to regions where the need is great.
Government Interaction:
No direct Government interaction is anticipated in this project. In the latter phases there may be some involvement in the licensing of manufacturers when they are provided with the tooling to injection mold the final version of the FullStop(TM) tap.
Ancillary activities:
The FullStop(TM) water tap may provide local opportunities for development by individuals or small businesses to distribute and sell units as part of rainwater harvesting systems in conjunction with micro-loan programs, school-led traning programs to design and install systems and the like.
The FullStop(TM) initiative encourages local entrepreneurship. The team, the partners, the product, the scope of the process (particualrly in focusing the eventual manufacturing proscess in developing countries) all make the BOR initiative highly entrepreneurial. BOR will distribute tooling at cost to many of the water-focused non-profits who are members of PWX. The tooling will be distributed at cost to the local manufacturers who can then sell the FullStop(TM) tap at affordable pricies to individuals and/or entrepreneurs. BOR and PWX and their on-the-ground agents will assit with creating water system installation businesses (rain catchment or production), creating opportunities and jobs where few have existed.
Other Issues:
Safe water for drinking and sanitation are clearly desperately sought commodities. Any component in the chain-of-events to implement this supply, such as a tap that both saves water and saves lives; is cheap to manufacture with few moving parts; is easy to repair and replace will quickly become an important part of water systems, particularly in the developing regions. BOR research (feedback via PWX) and on-the-ground experience in Sierra Leone shows that a weak link in any water system is often the tap, which is usually designed and manufactured for First World use. A vastly lower manufacturing cost of taps enables huge saving on system installations -- the high cost (target for theft) and low durability of imported taps often being a significant barrier to entry as well as long term success.
Water collection/distribution systems can be much more affordable using locally manufactured products, dispensing with acquisition/brokering/transportation costs, even using recycled (locally sourced) materials.
