Municipal Separate Storm Sewer System
A Municipal Separate Storm Sewer System (MS4) community owns or operates a system for collecting and conveying storm water. It does not include combined sewer overflows and publicly-owned treatment works.
Regulated conveyance systems include:

| Storm Drains | Gutters |
| Channels | Piping |
| Tunnels | Ditches |
| Conduits |
Water Quality
MS4 is an unfunded, federally mandated program that requires municipalities to take measures to reduce pollutants in stormwater runoff to improve water quality. The State requires the City of Alexandria to comply with this rule (327 IAC 15-13).

Alexandria's Storm Water Permit
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 5-year cycles, at the end of which the permit must be renewed. The City of Alexandria's NPDES permit was granted in ---- and renewed in ----.
Components
There are 6 components to the MS4 Water Quality Program:
| Construction Site Runoff Control | Illicit Discharge Detection and Elimination | Pollution Prevention and Good Housekeeping at Municipal Operations |
| Post-Construction Storm Water Management | Public Education and Outreach | Public Involvement and Participation |
Storm Water Quality Management Plan (SWQMP)
The SWQMP is divided into 3 distinct components.
Part A
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
Part B is the baseline characterization. The MS4 Operator provides information on the characterization of known water quality of all waters that receive storm water outfall discharges within the MS4 area in Part B.
Part C
The third component is the Implementation Plan which 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. This document is expected to change as issues are solved, best management practices are utilized, and technology improvements are developed.
