Water reuse and recycling improvement : Busanza housing estate-Rwanda.
Climate change could lead to longer and more frequent droughts for Rwanda. The option of water reuse, being independent of rainfall variations, provides a major source of water supply security for our growing cities. A 'soft path' for water management is widely acknowledged to be the sustainable future of water management. Decentralized wastewater reuse schemes form an important supply option in this 'soft path' approach. Discussion on water reuse and its role in sustainable water resource management in Rwanda has been on the agenda for the last decades. Despite its long presence on the agendas of policy makers and scientific community, promulgation of water reuse in Rwanda has been a rather slow process. The research efforts to date have focussed on the technological aspects of water reuse, leaving behind a gap in the area of policy and implementation aspects. This knowledge gap is even more severe when considering decentralised urban water reuse. Mathematical optimization has shown the potential to contribute to industrial water management, through the development of the solution methods needed for optimization-based design of wastewater treatment and reuse networks (also called water networks). The purpose of this proposal is for collecting all quantity of waste water to be treated so that they will be ready to be used again. The construction of the industries still under process but they are some that have been started. This process of water recycling will be easy for us because all industries are located at the same place, so the process will be done in conveying all waste water at the same place.
