Kejriwal made the appeal after inaugurating two electric sub-stations set up by New Delhi Municipal Council (NDMC) at Ali Ganj-Jor Bagh and Sarojini Nagar areas.
Kejriwal appealed to people to adopt water recycling technology and conserve water. He cited the example President Pranab Mukherjee, who he said had introduced this technology in Rashtrapati Bhavan.
The chief minister praised the NDMC for providing better civic facilities compared to other civic agencies.
NDMC chairman Naresh Kumar said the 33 KV electric sub-station at the junction of Aliganj and Jor Bagh cost Rs.5.5 crores and was completed in two years.
