Section 29(2) in Tamil Nadu Urban Local Bodies (Regulation and Monitoring of Swimming Pools) Rules, 2015
(2)Perimeter Overflow and Skimmers. - The perimeter overflow systems or automatic surface skimmers shall be kept clean and free of leaves or other debris which will restrict flow. The strainer baskets for skimmers shall be cleaned daily. The flow through each skimmer shall be adjusted as often as necessary to maintain a vigorous skimming action which will remove all floating matter from the surface of the water. The pool water shall be maintained at an elevation such that effective surface skimming is accomplished. For pools with perimeter overflow systems, adequate surge storage capacity should be maintained so that flooding of the perimeter overflow system does not occur during periods of peak usage.
