The city has grown richer by 3,240 rainwater harvesting structures.
The structures have come up mostly at newly constructed houses or apartment complexes and commercial buildings.
The Coimbatore Corporation has made rainwater harvesting mandatory to get a water supply connection.
The corporation had said that water connections would be allotted once water supply situation improves.
Assistant engineers in Wards would ensure that the applicants had indeed constructed the structures and that the structures were capable of harvesting rain water.
The physical verification was to avoid applicants getting away by just submitting photographs but not constructing the structures.
Sources in the corporation said that 600 more applications for water supply connection were pending.
The corporation had conducted awareness campaigns across the city by taking out rallies, distributing handbills, and educating the residents on the need to construct such structures.
The corporation wants residents to repair defunct rainwater harvesting structures at the earliest.
Water from the Siruvani Dam continued to overflow for the 13th consecutive day.
