Overview

Mammoth increase in the population of Bangalore city has resulted in rapid urbanisation and unplanned urban growth with serious consequences such as flooding on one hand and depletion of water table levels, on the other.  A performance audit on ‘Management of Storm Water in Bengaluru Urban Area’ was conducted to examine the existence and adequacy of the mechanism for management of storm water.  The scope, however, was not limited to infrastructure alone but looked into the larger aspect of redefining storm water as a critical natural source worthy of conservation.

The Performance audit covered the period 2013-14 to 2017-18.  Two valleys - Vrishabhavathi and Koramangala which included drain length of 467.10 km were selected for detailed scrutiny.  A few illustrative videos taken during joint inspection have been included in the report at relevant places by providing the link and also the QR code for scanning.

Audit also conducted an independent study of long-term changes in land use patterns utilising geospatial inputs with technical support from Regional Remote Sensing Centre–South, Indian Space Research Organization, Bengaluru (RRSC). Field visits and joint inspections substantiated the outcomes of this study.

The findings of the report are presented in different chapters.  Chapter 3 deals with Collection and conservation of Storm Water; Chapter 4 deals with Planning, designing and construction of storm water drains; Chapter 5 deals with Protection and maintenance of storm water management systems and Chapter 6 deals with Financial Management.
