The ancient Romans had better water quality than half the people alive today. Today’s water crisis is not an issue of scarcity, but of access. More people in the world own cell phones than have access to a toilet. And as cities and slums grow at increasing rates, the situation worsens.

Every day, lack of access to clean water and sanitation kills thousands, leaving others with reduced quality of life. The P3 BioSand Bag Filter is a highly effective and breathtakingly simple tool to solve this problem by bringing disease fee water to an entire community of 100 people per unit. Multiple units can be used in tandem for larger populations.

WHO & UN data documenting the problem:

The water and sanitation crisis claims more lives through disease than any war claims through guns. ( 2006 United Nations Human Development Report. ) 3.575 million people die each year from water-related disease. (World Health Organization. 2008. Safer Water, Better Health: Costs, benefits, and sustainability of interventions to protect and promote health. ) 884 million people lack access to safe water supplies; approximately one in eight people.  (UNICEF/WHO. 2008.  Progress on Drinking Water and Sanitation: Special Focus on Sanitation. )

A practical solution on the community level:

P3 = Proven, Potable & Portable

“Slow sand filters are recognized by the "World Health Organization"  [1],   Oxfam,   "United Nations" [2] and the  "United States Environmental Protection Agency [3] as being superior technology for the treatment of surface water sources. According to the World Health Organization, "Under suitable circumstances, slow sand filtration may be not only the cheapest and simplest but also the most efficient method of water treatment."

The P3 BioSand Bag Filter delivers a proven method for potable water treatment in a way that is simple, green and portable - mostly comprised of locally sourced parts. Each 100 person capacity unit removes bacteria and viruses from untreated water, reducing water borne diseases.

The P3 BioSand Bag Filter is breathtakingly simple, yet effective. It is comprised of fewer than 20 parts that enable the process of slow sand filtration, which was developed in ancient Egypt and widely used by town & cities today. To minimize costs, the P3 BioSand Bag Filter ships from locations worldwide and close to the end user. Component parts were selected because they are universal and available at low cost worldwide in order to a) minimize cost and b) benefit the end user’s local economy
