Aim

Establish and demonstrate a prototype of water, nutrients and energy recovery system to foster decentralized water circularity at the ward level

Map and quantify the water balance in and around Ward 50, including inflow, outflow, wastewater generated, and water reuse. Quantification may include estimations of evaporative losses. Inflow should consider rainfall and water acquired from outside the Ward boundaries. Likewise, outflow must consider water used within the Ward and water that flows out of the Ward.
Identify key indicators through stakeholder engagement to assess circular and sustainable water resource management in the ward (e.g. rainwater harvesting) through understanding infrastructure, technological, policy, social, economic and related knowledge gaps. Based on this, develop the top 3-5 indicators to assess.
A pilot-scale demonstration of a decentralised water-nutrient-energy recovery system based on the first and second outcomes. According to total water budget equations, demands, quality and quantity of various parameters we will choose best-fit technology.
