The Haryana Urban Development Authority (HUDA) also made rules in the same year. Under regulation 81A of Haryana Urban Development Authority (Erection of Buildings) regulations 1979, the Deputy Commissioner told that arrangement of rooftop rain water harvesting was made mandatory for obtaining completion certificate in the buildings where the area of roof is 100 Sq. meter or more. She told that the system of collection, conveyance and dispersion of rain water for harvesting should be made in such a manner that only clear water is able to enter into the earth. No contaminated for waste water from the building or surrounding areas should finds its way in this system. The entry points of rain water for harvesting should be design such a manner that in normal days these remain closed.
The DC while appealing the people to adopt rooftop rain water harvesting system in their premises said that the design can be obtained from the office of Additional Deputy Commissioner or from Hydrologist.
