Design Projects
Spring 2009
Agalteca
Agalteca is a community with 2160 people that distributes their water from a nearby river. A preliminary design was done for budgeting purposes and fundraising is currently being conducted.
Atima
Atima is a potential community with a population of 3300, or 550 homes. A design flow rate is being given of 270gal/min to account for estimated future demands. A preliminary design was created in order for the town to evaluate the budget.
Gracias
We are currently working on the Gracias design.
Ecuador Design
The Ecuador pilot plant was designed for a University professor. The plant was designed to have a flow rate of 3L/s. This pilot facility is designed to be viewed by other communities in the hope of encouraging the AguaClara technology as a water treatment option. This design will further allow research to be conducted by including redundant systems. Construction is set to begin in late May, without the assistance of our engineers in Honduras.

\\ \\ Details of the design can be found below. * [Cuatro Comunidades Detailed Design|Cuatro Communidades Design] * [Community Details and Construction|Cuatro Comunidades] h3. Gracias We began the semester trying out new set-ups for the Gracias community which required a flowrate much higher than previous designs. Quanititatively, the flow rate for our plant designs have increased from 500 gal/min in Marcala to 1600 gal/min in Gracias. The design results can be seen below. Due to the large flow rate, it was ultimately decided that Gracias would have a triple width sed tank--there will be 3 pairs of slopes for each sed tank. The variable widths of the sed tank will later be automated to account for higher flowrates. Experimental setups are included below that discuss the different alternatives we considered, such as varying the width of the sed tank (or number of pairs of slopes) and number of sed tanks. * [Gracias Rough Designs and Layouts|Gracias Experimental Set ups] * [Gracias Final Design|Gracias Design] * [Community Details and Construction|Gracias] h3.

The plant in Marcala was built in partnership with Fred Stotlemeyer and NRWA. It was designed as a retrofit on an existing plant structure. The typical AguaClara layout was altered so that our design would fit in the existing tanks. At the time of completion in July 2008 Marcala was the largest plant designed by AguaClara; currently it has only been surpassed in size by the Gracias plant.

The Ojojona plant serves a population of 2000 people at a flow rate of 375 L/min. The plant is one of the first to incorporate our current flocculator design--vertical versus horizontal flocculation. This plant also incorporates plate settlers in three sedimentation tanks.
Fall 2004
La34
La 34 was the first plant constructed by the AguaClara team. It is the only plant that uses a horizontal flow flocculator technique.
Project Sites
A complete list of completed designs can be found on the Project Sites page. This page is maintained by students in Honduras working on the plants and supervising the construction. It provides a background of the site, as well as updates regarding construction and operation.
Design Modifications
As the AguaClara team continues to build plants and continues to learn more about the details of optimizing water treatment processes, changes are made to the design algorithms. For an outline of what significant changes we have made designs over the years check out the Design Modifications Page
