B-9 Plastics Better Water Maker

B-9 Plastics Better Water Maker

This project is part of the Sustainable Water Systems family on the Senior Design Project Roadmap with the mission to provide a compelling solution to the problem of sufficient, accessible, economical and sustainable potable water supplies for the worlds population.

The goal of this project is to improve two UV systems that began at RIT and are already being used in Haiti, Guatemala and other countries.

Clean Water for the World, a non-profit organization, was started to improve the design of the UV system, fitting most of the components into a wooden box that doubles as a shipping container. Sarah Brownell has been using their system in 4 locations in Haiti for three years and suggests the following areas for improvement that would be tackled by the Multidisciplinary Design Team:

  • Generally reducing manufacturing costs, possibly incorporating Design for Manufacture.
  • Redesign of the shipping container and UV housing, using lighter/cheaper/more compact materials
  • Design for reducing insect sabotage (cockroaches took down one of the UV units by eating off the wires insulation and causing a short)
  • Improving the user interface and ease of completing cleaning and maintenance steps.
  • Designing in incentives for the operator to keep the unit running. Clean Water for the World requires that the water be given away for free, which means the operator must volunteer to provide their community with water, do maintenance, and replace parts for free.
  • Improving the power system and making it easy to install and connect the system.
  • Redesign of the UV disinfection chamber to reduce costs.

B9 Plastics is a not for profit company and one of their most prominent projects is a UV treatment device called the Better Water Maker. The Better Water Maker is a batch UV system that treats about 5 gallons of water at a time using a hand crank to provide power to the UV light. However, users in Haiti report that the hand pump was difficult to use and led to variable power supply. The multidisciplinary senior design team will work to improve the manual power generation capability of the Better Water Maker.
