In January 2013, the Low Flow Stacked Rapid Sand Filter was tested in Honduras. Although the filter worked, it quickly failed due to structural weaknesses. The primary tasks this year included improving the durability of the filter and increasing the ease of operation. New manifold and sand drain designs are in the process of being implemented. Additionally, the stacked rapid sand filter went to Washington, D.C. in April for the EPA P3 competition. A written approval for the P3 grant was written and submitted. To demonstrate the design and effectiveness of the LFSRSF, a fully operational unit was designed. The prototype underwent hydraulic and performance testing and operated well at the competition.
