The EWB challenge is established as an initiative to approach first year university student to the real responsibilities of an engineer. This challenge is managed by Engineer Without Border Australia cooperating with different type of organizations, across many industries. This challenge has been revealed in 2007, it has spread and cooperate with 26 universities around Australia. In the previous year, EWB held a workshop with Nepal Water for Health (NEWAH) staff in their regional office in Bharatpur.
For the 2014-2015 challenge, EWB has collaborating with NEWAH and several organizations. This challenge is focusing on the hill region communities of the Gorkha district. There are seven design areas that have been identified to be- work for this challenge. One of them is waste management of the village. Students has been deputed to create integrated design solution for this design area. Community health, the environment and the potential uses for this by-product must take into consideration when doing the solution.(EWB 2014)

The objective of this proposal is to overcome problems arising from the septic tank which has been use by the villagers nowadays for their sanitation. Besides, the by-product of this design will be used to enhance village agriculture and ease their daily life.
