  • Abstract:
  • A water crisis is one of the major issues prevailing in various regions of the world. Fulfilling the growing demand with available limited fresh water resource is significantly faced by urban water supply authority. Hence urban areas felt a great need to explore alternative measures for satisfying the growing demand of water. Application of resiliency for urban water management can be act as an effective tool. Resilience means “The ability to survive a crisis and thrive in a world of uncertainty” Resilience points towards the capacity of a social–ecological system to absorb or withstand perturbations and other stressors such that the system remains within the same regime. Urban water resiliency could be achieved by using the treated wastewater to meet gap between water demand and supply. Kalyan Dombivli is the fastest growing urban hub in the vicinity of Mumbai. Kalyan Dombivli Municipal Corporation (KDMC) is having acute water shortage during dry seasons. Also ground water table in the city is depleting fastly. Therefore, sustainable water demand management (SWDM) is essential in this city. The Municipal Corporation has an area of 67.65 sq. km. The present piped water supply of the city from Ulhas River is 320 Million Litres per Day (MLD) against demand of 370 MLD including water for gardening and flushing. Therefore in present study an attempt is made to explore the possible application of recycled water for building water resilience of Kalyan Dombivli City. Sewerage system of KDMC has been divided into 7 zones. The total Sewerage Network is 300 Km in length. KDMC has total 08 sewageTreatment Plants (STP’s) with treatment capacity of 210 MLD. The sewage is mainly treated for organic and inorganic constituents. Presently KDMC generates 66 MLD recycled water. The treatment achieves reduction of BOD & suspended solids from 200 mg/litre and 350 mg/litre to less than 10 mg/litre and 100 mg/litre respectively. The pH of treated water is achieved in the range of 7.0 to 7.3. This recycled water is satisfying the standards prescribed by Maharashtra Pollution Control Board for reuse and which could be effectively used to satisfy the water demand for gardening (15MLD) and flushing (35MLD) purpose of residenti
