System for increasing and displaying effectiveness and efficiency of stormwater infrastructure

A method of operating a stormwater BMP, the method comprising:

• measuring a volume of stormwater runoff introduced into a storage gallery of a BMP due to a precipitation event using at least a fluid level sensor disposed in the storage gallery;
• measuring a first portion of the volume of stormwater runoff that is removed from the storage gallery through a drain system in fluid communication with the storage gallery using at least one fluid flow sensor disposed on the drain system;
• and
• determining a second portion of the volume of stormwater runoff that is either maintained in the storage gallery or permeates through a subgrade adjacent to the storage gallery.

An active water storage infrastructure management facility operating system comprising:

• a permeable pavement surface;
• a permeable base material disposed under the permeable pavement surface;
• an underdrain system comprising a plurality of individual drain lines and having at least one outflow point;
• a control system for managing the operations of the water storage infrastructure;
• a plurality of sensors for measuring one or more operating parameter, the sensors disposed in the underdrain system, each of the plurality of sensors in electronic communication with the control system;
• at least one outflow valve disposed at the outflow point, said outflow valve in electronic communication with the control system;
• and
• wherein the control system operates the outflow valve based upon the measurements of one or more of the plurality of sensors.
