The existing collection system of the village is devided into two portions the largest services about 300 homes in the village. With the second serving just under 200 homes.
After our trip we have decided that the current collection system is in good condition and does not need to be designed. We did map a large portion of the system using a GPS unit.
The treatment facility is the largest part of the design. An initial parameter for this from HCJB is that it must be a passive method of treatment Passive treatment will not include any motorized processes such as pumps, aerators, mixers, mechanical raking system and more. In addition to being passive the facility is constrained by cost and the amount of land that it can take up. The treatment options we are currently pursuing are bar screens, a series of wastewater ponds, and infiltration beds. A possible flow diagram of the future system may look like the figure below.
The effluent of the current design will be infiltrated into the ground. The desired qualities of particular containments are seen in the table below. Using the effluent for irrigation may be looked into after traveling to Carabuela

The design is divided into three parts: the collection system, the treatment facility, and the effluent. Each part is detailed in the tabs at the bottom of the page.
On our trip to Carabuala we will establish a greater relationship with the people that this project will serve. Our goal is to maintaing a Christ honoring image to whoever we come into contact with during this project and in all areas of life.
The project is designed for those who cannot pay for this system on their own. It is crucial that the operating costs do not exceed what they can afford. This project is to not remove their way of life but be integrated into their way of life.
