Flow control structure and related media filtration system
View Patent ↗A stormwater filtration system includes a stormwater containment structure including a bottom surface, an inlet that receives stormwater and an outlet through which filtered stormwater exits the stormwater containment structure. A flow structure is at the bottom surface. The flow structure includes a conveyance conduit running along the bottom surface of the stormwater containment structure and in fluid communication with the outlet of the stormwater containment structure. The conveyance conduit includes a port extending through a sidewall of the conveyance conduit. A saddle includes an upper component and a lower component connected to the upper component such that the upper and lower components straddle the conveyance conduit at the port. The upper component includes an opening in communication with the port and the lower component supports the conveyance conduit above the bottom surface.
1. A stormwater filtration system, comprising:
a stormwater containment structure including an inlet that receives stormwater and an outlet through which filtered stormwater exits the stormwater containment structure;
a plurality of spaced apart saddle structures positioned along the bottom of the containment structure, each saddle structure including a conduit support passage therethrough, the conduit support passages of the spaced apart saddle structures aligned with each other;
a conveyance conduit extending through the aligned conduit support passages of the plurality of saddle structures, the conveyance conduit including a plurality of sidewall ports, each sidewall port aligned with an opening of a respective saddle structure;
a plurality of filter units, each filter unit connected to a respective one of the saddle structures, such that filtered water from each filter unit flows out from a filter unit outlet, through the saddle structure opening and into the sidewall port of the conveyance conduit.
2. The system of claim 1 wherein the conveyance conduit is in fluid communication with the containment structure outlet.
3. The system of claim 1 wherein each saddle structure comprises multiple components connected together to form the conduit support passage.
4. The system of claim 3 wherein the multiple components each include a surface portion that forms part of the conduit support passage.
5. The system of claim 1 wherein the conveyance conduit is supported above the bottom surface of the containment structure.
6. The system of claim 5 wherein each filter unit is positioned above the conveyance conduit.
7. The system of claim 1 wherein a filter unit connector releasably connects each filter unit to it its respective saddle structure.
8. A stormwater filtration system, comprising:
a stormwater containment structure including an inlet that receives stormwater and an outlet through which filtered stormwater exits the stormwater containment structure;
a plurality of spaced apart saddle structures positioned along the bottom of the containment structure, each saddle structure including a conduit support, the conduit supports of the spaced apart saddle structures aligned with each other;
a conveyance conduit extending along and supported by the aligned conduit supports, the conveyance conduit including a plurality of sidewall ports, each sidewall port aligned with a respective one of the saddle structures;
a plurality of filter units, each filter unit connected to a respective one of the saddle structures, such that filtered water from each filter unit flows out from a filter unit outlet and travels into the sidewall port of the conveyance conduit;
wherein the conveyance conduit is supported above the bottom surface of the containment structure and each filter unit is positioned above the conveyance conduit.
9. A stormwater filtration system, comprising:
a stormwater containment structure including an inlet that receives stormwater and an outlet through which filtered stormwater exits the stormwater containment structure;
at least one saddle structure positioned at the bottom of the containment structure, the saddle structure including a conduit support passage therethrough;
a conveyance conduit extending through the conduit support passage and having a sidewall port aligned with an opening of the saddle structure;
a filter unit connected to a respective one of the saddle structures, such that filtered water from the filter unit flows out from a filter unit outlet, through the saddle structure opening and into the sidewall port of the conveyance conduit.
10. The system of claim 9 wherein the conveyance conduit is supported above the bottom surface of the containment structure and the filter unit is positioned above the conveyance conduit.
