Designing a Local Waste Water Management System

The Matendla School staff and students recently successfully completed the construction of a soak pit in order to increase the amount of groundwater for use in the school. This school community project shows us once again the power of collective intention and empowered action! The idea came forth after the high school students visited the model village of Hebrahimpur, where a soak pit project was undertaken as a village initiative and each family participated to ensure completion.

The water coming out of the septic tank is not pure. Therefore, the primary purpose of having a soak pit is to receive this effluent water, called ‘greywater’, from the primary treatment unit e.g., the school’s septic tank. The soakpit treats this greywater coming from the septic tank and discharges clear and non-harmful water into the ground. The greywater that passes through the soak pit gets filtered, which results in the smaller particles of effluents settling at the bottom of the soak pit, which get digested by microorganisms and is a sustainable degradation process. The filtered water then discharges through the porous walls of the soak pit, resulting in clean water being discharged into the environment.

The design to execution process managed by the students and non teaching staff also turned out to be a great way for students to understand waste management systems and the engineering that goes into it. The students enjoyed doing this hand-on project, adding a lot of knowledge to the topic of waste water management.
