Flow imaging and monitoring for synchronized management of wide area drainage

An interposer for supporting equipment in a manhole comprising:

• adjustable length tubing;
• a locking mechanism to retain the adjusted length tubing to accommodate various diameter manholes;
• splayed brackets to contact the vertical plane of the inner rim of a manhole;
• locking mechanisms to prevent separation of the brackets from the tubing;
• one or more enclosures or holsters suspended from the tubing by adjustable clamps;
• and
• one or more devices securely fastened to the tubing.

An interposer for supporting equipment in a manhole comprising:

• a double channel rail strut;
• offset brackets with integrated strut plate for adjustment of the double channel rail strut;
• one or more enclosures or flexible sleeves suspended from the double channel rail strut by adjustable clamps;
• and
• one or more devices securely fastened to the double channel rail strut.

An interposer structure for supporting equipment in a manhole comprising:

• an interposer rod;
• a single channel rail strut;
• offset brackets with integrated strut plate for adjustment of the single channel rail strut;
• one or more enclosures or flexible sleeves suspended from the single channel rail strut by adjustable clamps;
• and
• one or more devices securely fastened to the single channel rail strut.

A sealed, rechargeable battery pack for use in wet environments comprising:

• a sealed enclosure;
• encapsulated power and output cables;
• a plurality of rechargeable battery cells;
• and
• a microcontroller to control on-time of the cells only when needed, mapping around dead cells, re-charging of the individual power cells, and signaling when recharge of the entire sealed battery pack is necessary

A method of flow imaging, monitoring and management of storm water and wastewater comprising:

• placing an interposer supporting, at least one module for monitoring response to reflected or transmitted light, a sealed and rechargeable battery pack, and a data capture, processing, and communication system in a manhole;
• illuminating the water flowing at the base of the manhole with ambient light or light of varying frequencies and wave-lengths;
• measuring the width, shape and velocity of the water flowing at the base of the manhole;
• interpreting the water flow characteristics in real time using a data capture, processing and communication system;
• sending the interpretation to a cloud computer;
• and controlling the data capture, processing and communications system from the cloud computer.
