BOBOLINK WATER TREATMENT PROJECT

Using Fazenda Ambiental Fortaleza as a model, the Bobolink Water Treatment Project is an initiative to bring the same level of water cleanliness, treatment and conservation to the participant producers of Bob-o-Link Coffees.

Objective:  To provide simple, low-cost and effective treatment of household waste (grey and black water) for a single-family residence that currently relies on an unprotected septic system.

Step 1 - Grease Trap   A simple grease trap that catches the grey-water solids from the kitchen. This allows a preliminary treatment of the grey water before it flows to the Biodigester Septic Tank

Step 2 – Biodigester Septic Tank   Black water waste flows directly into the Biodigester Septic Tank and is mixed with the output from the grease-trap. Slightly more complicated than a normal septic tank, it is much more efficient than a normal septic tank and allows the solids to be removed by gravity. It is not required to hire a removal service with a tank and pumps. The home owner can do this annually and stores the solids in a drying tank on the premises. This then becomes compost!

Step 3 – Wetland Filtration system   This is a planted living garden that receives the liquids from the biodigester and filters them through the root-system and soils of the garden. Usually two gardens are planted. The first has a protective sheeting surrounding the plants that protects the local eco-system from the water being treated The second garden receives the relatively clean water and returns the final treated liquids to the environment via infiltration and evaporation.
