What we do

The Storm Water Utility provides comprehensive and integrated management of Franklin's storm water infrastructure through best management practices in storm water management. The Utility is responsible for the implementation of the Municipal Separated Storm Sewer System (MS4) Program mandated by the Indiana Department of Environmental Management (IDEM).

What is an MS4?

MS4 stands for Municipal Separate Storm Sewer System.  An MS4 community owns or operates a system for collecting and conveying storm water.  Regulated conveyance systems include roads with drains, municipal streets, catch basins, curbs, gutters, storm drains, piping, channels, ditches, tunnels and conduits.  It does not include combined sewer overflows and publicly owned treatment works.

MS4 is an unfunded, federally mandated program that requires municipalities to take measures to reduce pollutants in storm water runoff to improve water quality.  The state requires the City of Franklin to comply with this rule (327 IAC 15-13).

The MS4 is permitted under the National Pollutant Discharge Elimination System (NPDES) program through the Indiana Department of Environmental Management (IDEM).  MS4 permits are granted in five-year cycles at the end of which the permit must be renewed.

What is a Storm Water Quality Management Plan (SWQMP)?

The SWQMP is divided into three distinct components. The first part of the SWQMP is Part A or the initial application.  Part A includes a general budget sheet used to indicate to the State that a budget allocation has been made to the MS4 Program.

Part B is the Baseline Characterization. The MS4 Operator provides in the Part B information on the characterization of known water quality of all waters that receive storm water outfall discharges within the MS4 area.

The third component is the Implementation Plan and is designated as Part C.  Part C is the working document that outlines the priorities, goals, and implementation strategies that the MS4 will utilize to improve water quality. It is expected that this document will change as issues are solved, best management practices are utilized, and technology improvements are developed.
