Presentation held in the course of the BASF Creator Space™ tour stop Mumbai by Dr. Rakesh Kumar, National Environmental Engineering Research Institute (NEERI)

1. Looking At Water In Different Colours
For Better Management

2.  Water source limitations
 Water losses: Real and hypothetical
 Actual water use and supply issue
 Disconnect of water with waste water
Mumbai and Mumbai Metropolitan Region sustainability:
Water resources

3.  Source protections from over exploitation and external pollution
 Huge losses through leakage, contamination and theft of water
~35 – 45 % loss in Mumbai through leakages/non revenue water
 Congestion and complexities of network constricting laying of new
standby pipelines
 Present Situation
Current demand in MMR region = ~ 8316 MLD
Availability = 6222 MLD
Current deficit = 2094 MLD
Major challenges: Water

4.  About 80 % of water supply ends as wastewater, which can be a
water source too?
 Question of treatment and disposal
 Large areas of marine and fresh water bodies impacted by these
discharges
 Reuse can be a possibility: how?
Major challenges: Water

8.  Is the present “policy” good for conservation ?
 Water footprint tracking….but how?
 Do we need “water managers”?
What could be desirable…for the city: Water

9.  Can water and waste water policy and institutional framework
work together?
 Waste Water reuse……is it a good option ?
 Water harvesting in place of RWH?
 Smart Managers for water and wastewater ?
What about Waste Water
