"If making a city open defecation free is a challenge, sustaining it is an even bigger challenge. It is heartening to see that cities have shown resolve by collaborating with the citizens in making cities Open Defecation Free. I am glad that Swachh Bharat Mission is being integrated with other schemes such as AMRUT and Smart Cities I appeal to all the cities to make ODF a sustainable practice." - SHRI HARDEEP SINGH PURI
