Stormwater pollutant separation system and method of stormwater management

A stormwater pollutant separator system, comprising

• a stormwater pollutant separator having a first end and a second end, said stormwater pollutant separator comprising a chamber, said chamber having a top and a bottom, a weir plate attached to and extending upwardly from said chamber bottom, a siphon plate attached to and extending downwardly from said chamber top, a plurality of access risers attached to and extending upwardly from said stormwater pollutant separator, said first end having an intake aperture formed therein, said second end having an outflow aperture formed therein, said chamber comprising a first section, a second section, and a third section, said first section being located between said first end and said weir plate, said second section being located between said weir plate and said siphon plate, said third section being located between said siphon plate and said second end, said first section having an inspection/maintenance riser connected thereto and extending upwardly therefrom, said second section having an inspection/maintenance riser connected thereto and extending upwardly therefrom, and said third section having an inspection/maintenance riser connected thereto and extending upwardly therefrom, said third section having filter material placed intermediate said siphon plate and said second end, said filter material being adjacent said outflow aperture,
• a by-pass system having a first end and a second end,
• an intake conduit connecting said first end of said stormwater pollutant separator and said first end of said by-pass system, and
• an outflow conduit connecting said second end of said stormwater pollutant separator and said second end of said by-pass system, said third section having a standpipe, said standpipe having a top and a bottom, said standpipe top attached to and extending downwardly from said chamber top, said standpipe having a plurality of apertures formed therein said filter material placed within said standpipe.

A stormwater pollutant separator comprising

• a chamber, said chamber having a top, and a bottom, a first end and a second end, said first end having an intake aperture formed therein, said second end having an outflow aperture formed therein, a weir plate attached to and extending upwardly from said chamber bottom, a siphon plate attached to and extending downwardly from said chamber top, and a plurality of inspection/maintenance risers attached to and extending upwardly from said stormwater pollutant separator, said chamber comprising a first section, a second section, and a third section, said first section being located between said first end and said weir plate, said second section being located between said weir plate and said siphon plate, said third section being located between said siphon plate and said second end, said first section having one of said inspection/maintenance risers connected thereto and extending upwardly therefrom, said second section having one of said inspection/maintenance risers connected thereto and extending upwardly therefrom, and said third section having one of said access risers connected thereto and extending upwardly therefrom, said third section having filter material placed intermediate said siphon plate and said second end, said filter material being adjacent said outflow aperture, said third section having a standpipe, said standpipe having a top and a bottom, said standpipe top attached to and extending downwardly from said chamber top, said standpipe having a plurality of apertures formed therein, said filter material placed within said standpipe.

A stormwater pollutant separator system, comprising

• a stormwater pollutant separator having a first end and a second end, said stormwater pollutant separator comprising a chamber, said chamber having a top and a bottom, a weir plate attached to and extending upwardly from said chamber bottom, said weir plate extending completely across said chamber at a height less than the height of said chamber, a plurality of access risers attached to and extending upwardly from said stormwater pollutant separator, said first end having an intake aperture formed therein, said second end having an outflow aperture formed therein, filter material being inside said chamber adjacent said outflow aperture, said filter material filtering out heavy metals,
• a by-pass system having a first end and a second end,
• an intake conduit connecting said first end of said stormwater pollutant separator and said first end of said by-pass system, and
• an outflow conduit connecting said second end of said stormwater pollutant separator and said second end of said by-pass system.

A method for separating floating and non-floating material from stormwater drainage, comprising the steps of:

• inducing said stormwater drainage initially into a stormwater pollutant separator for flow therethrough;
• containing the majority of all non-floating material by the use of a weir plate within said stormwater pollution separator;
• said weir plate extending completely across said stormwater pollution separator at a height less than the height of said stormwater pollution separator.
• containing the majority of all floating material within said stormwater pollution separator;
• discharging said stormwater drainage from said stormwater pollutant separator;
• providing a by-pass system for introduction of stormwater drainage thereinto for flow therethrough when the level of stormwater drainage awaiting introduction into said stormwater pollutant separator results in overflow into said by-pass system;
• and
• discharging any stormwater drainage from said by-pass system into the stormwater drainage discharged from the stormwater pollutant separator.
