How Integrated Asset Management Can Assist in Meeting Your MS4 NPDES Permit Requirements.
Stormwater inlets, tributary drainage areas, water quality BMPs, and outfalls/discharge points are subjected to National Pollutant Discharge Elimination System (NPDES) stormwater regulation. Municipal Separate Storm Sewer System (MS4) permits often ask permittees to identify and describe these stormwater assets. This translates to a significant amount of resources dedicated towards the inventory of existing facilities, and proposed facilities, as part of new construction or retrofit mandates. Furthermore, stormwater asset tracking and management are necessary due to the MS4 Permit-required periodic maintenance and reporting of these stormwater assets.
This presentation will focus on the use of technology and challenges overcome in stormwater asset management not only for existing facilities, but also for proposed facilities starting from planning and design, through construction and operation & maintenance. Technology has improved dramatically such that, hardware-wise, we are now using clipboard-sized tablets that combine a global positioning system (GPS), camera, and laptop for field inventory. Software-wise, Geographic Information System (GIS), interactive maps, and apps can be customized to easily fit our asset management field inventory needs. Furthermore, a scalable MS4 permit database, BMP asset map tools, and data management will be discussed. Data are being displayed on the web viewer (spatial and non-spatial). The web viewer is a developed Web service that users can access the map tools and its data in either an Apple or PC desktop as well as iOS, Windows, or Android mobile tablets and smart phones. Open source GIS and Google based Application Program Interface (API) are potential alternatives to ESRI products depending on compatibility and preferences.
A web-based demonstration will take place with audience interaction and a Question and Answer session.
