How Technology Has Evolved As Your Resource For Meeting Your MS4 NPDES Permit Requirements

Track / Session:
Stormwater and Technology / Emerging Trends and Strategies for Open Data and NPDES Compliance

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 have evolved to asking permittees to identify and describe these stormwater assets and their maintenance information through a database in addition to pollution prevention and treatment. 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.
This presentation will focus on the evolution of technology and overcoming challenges 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.
