DayOne Response: Polytech Waterbag, Water Treatment for Disaster Relief

California Polytechnic State University-San Luis Obispo, 2009 - $20,000

The Polytech Waterbag is a water filtration bag with disinfectant to be used in disaster relief situations. Developed and marketed by DayOne Response, the Waterbag will be sold to relief organizations and governments.

Providing people with clean drinking water is the one of the biggest challenges following a natural disaster. The most common solution is having aid agencies and governments deliver large five-gallon jugs of water, which is a costly and slow undertaking. Other solutions (hand-pumped filters, chlorine tablets) are either too expensive or only partially effective at treating contaminated water. This E-Team is developing a new way to ensure people have access to safe drinking water after a disaster: the Polytech Waterbag (PW). The PW is a ten-liter plastic bladder equipped with carrying straps and an integrated filter with a dispensing port. It’s designed to be used with Procter & Gamble’s PUR® chemical treatment packets; by using the packet along with the filter, complete water purification can be achieved. The PW comes with other features as well: a wide mouth for easy filling in shallow streams, a sediment trap to prevent recontamination, and more. The bags are 20x more compact than five-gallon water jugs to ship, and can treat enough water to supply a family of four for 5-10 days. The team has developed and patented a prototype, participated in and won several business plan competitions, and worked with Clinton Global Initiative project.

In 18 short months, NCIIA E-Team DayOne Response has moved from a student team with a cool idea to a company with a disaster-relief product being field tested by the US and Thai Marine Corps. Here's the story in pictures:

Quick facts:

May 2009: awarded a $20K E-Team grant.

Nov. 2009: attended Advanced I2V workshop to develop business strategy.

March 2010: showcased the waterbag at Open Minds.

April 2010: incorporated as DayOne Response, and wins a contract with the US Navy to continue R&D on the waterbag via a joint technology exercise between the US and Thai Marines. The waterbag was one of the few technologies in that exercise to meet US military objectives for Humanitarian Aid and Disaster Relief missions.
