Conserve each and every drop !!!

What is happening, Now ?

Inflow of untreated sew age & industrial effluent Poor Catchment due to

♦ Non-point Pollution sources (Open defecation, Cattle farms etc.) ♦ Leaching from indiscriminate solid waste dumping. ♦ Run-off from agricultural fields.

Water Management Challenges in India

Groundw ater Over-exploitation Contamination

Need for Technological Innovation, Adaptation & Sustainability

Surface Water Non-point Pollution Untreated Discharge Wastew ater Treatment Urban Areas (30-35%) Performance Varies Water Quality Monitoring Lack of Reliable Data Lack of Infrastructure Need for Integrated Water Resources Management !!

Water Budget : India

Water Resources are highly stressed !!

Irrigation Purpose Industrial Applications Domestic Use

Infrastructural Projects

Water is Essential for Sustenance of Life

Why Water Resources Management ?

Major Issues :

Water Scarcity Water Contamination/ Pollution Water Quality Varies Widely

Needs to be addressed !

Over Exploited Critical Semi Critical Safe

State-w ise Stages of Groundw ater Development

Major Hotspots are Delhi, Haryana, Punjab & Rajasthan followed by Gujarat, Tamilnadu, U.P & Karnataka

River Basins in India

% contribution in sectoral water demand

Due to Population Pressure & Growing Water Demand : River Basins are moving towards stress !!!

Ganga River Basin is the largest

Sew age Generation & Treatment in Ganga Basin States (Urban Areas Only)

Sew age Generation in Ganga Basin States : 27068 MLD Existing Operation Capacity : 7356 MLD (27.2 % only) Maximum operational capacity 2671 MLD in Delhi

State-w ise Sew age Treatment Status (Urban Areas of India as on 2015)

Sew age Treatment Essential for IWRS

Treatment Capacity 23277 MLD (39%) No Treatment 39723 MLD (61%)

Sewage Generation in Urban Area 61000 MLD Actual Sew age Treatment in Urban Areas of Country

Intense Need for Augmentation
