Fluid stream management systems and methods relating thereto are described. The fluid management system includes: (1) one or more storage chambers; (2) two or more flow condition attribute measuring devices configured to measures certain flow condition attribute values; (3) one or more flow controllers that are communicatively coupled to receive the flow condition attribute values and use them to establish certain cost functions; and (4) one or more flow-modifying devices, each of which is coupled to at least one of the flow controllers, and based upon instruction received from at least one of the flow controllers, the flow-modifying device is capable of modifying flow of fluid through one or more of the flow-modifying devices to minimize a difference between the established cost functions.

A combined sewer/enclosure overflow (CSO) sensor system is described for accurate detection and measurement of overflow events. From the combined data, trending information can determine if there is debris accumulation. Rain masks can be used in the trending data to measure overall health. External sensors in combination with the CSO sensors provide predictive information and additional levels of information/data accuracy. The sensor system automatically and remotely monitors CSO locations and provides real-time data regarding start times, stop times, duration, and flow volumes of overflows that occur in these structures and provide regulatory and public notification of these events.

Sewage flowing into a second water branching device is accurately controlled to separate into the following: sewage with a maximum sewage volume that can be discharged into a public water body W, the sewage sequentially passing through a first regulating tank, a first orifice, a second regulating tank, a second orifice, a third regulating tank and a third orifice to flow into a second discharge pipe; and sewage with an excess sewage volume, the sewage overflowing first to third overflow weirs to flow into an inflow pipe for a regulating reservoir.

A feed storage arrangement for use with a sheet like feed barrier, the storage arrangement comprising at least one elongated leachate channel having an outlet end; and at least a first feed pad section extending along at least a portion of a length dimension of the leachate channel, the first pad section including first and second lateral edges and upper and lower edges wherein the first lateral edge is located proximate the leachate channel, the second edge is spaced apart from the first edge, the upper edge is proximate the outlet end of the leachate channel, and the lower edge is opposite and spaced from the upper edge, the first pad section sloped downward starting at the second edge and toward the first edge, wherein, with feed supported on the first pad section adjacent the leachate channel, the feed barrier is positionable on top of the feed with an edge portion extending over the leachate channel to a side of the leachate channel opposite the first pad section.

Fluid stream management systems and methods relating thereto are described. The fluid management system includes a neural network, which comprises: (i) an input layer that is communicatively coupled to one or more fluid facility sensors and/or one or more pre-processing flow sensors such that one or more of the flow condition attribute values are received the neural network; (ii) one or more intermediate layers, which are configured to constrain one or more of the flow condition attribute values to arrive at modified flow condition attribute values; (iii) an output layer, which transmits, one or more modified flow condition attribute values to a downstream control device. This control device and other computation devices perform certain calculations that ultimately inform a flow controller, which in turn, instructs a flow-directing device regarding management of fluid streams.

Fluid flow enhancing devices disclosed herein are adapted to enhance flow of fluid through subsurface watershed conduits, for example, culverts, drainpipe and the like. Such fluid flow enhancing devices advantageously enhance watershed runoff functionality in subsurface watershed conduits by altering watershed flow from a parabolic flow pattern to a rotational flow pattern while still accommodating fish passage requirements. This change in flow pattern beneficially provides turbulence that disrupts and flushes debris out of the subsurface watershed conduits. This disruption and flushing establishes a passive cleaning functionality within the subsurface watershed conduits that serves to clean the subsurface watershed conduits after suitable upstream water delivery event (e.g., heavy rain, controlled water release, etc.). In doing so, these fluid flow enhancing devices overcome one or more shortcomings associated with subsurface watershed conduits in a manner that overcomes drawbacks associated with conventional design and in-use considerations for such subsurface watershed conduits.

System for drainage of surface water, the system comprises a number of tanks being connected to a main pipeline leading water to a recipient. Each tank has at least one outlet for leading water from the tank to the main pipeline, and a corresponding lid, the lid is limiting the outlet until the water is at a predetermined level in the tank. The system further comprises a check valve arranged downstream of the outlet of each tank, preventing water from entering the tank from the main pipeline, and at least one air bleeder valve and at least one siphonic drainage regulator arranged between a tank and the recipient.

The present invention discloses a heavy metal separating device and a parameter determining method. The device includes a plurality of pipe sections and a plurality of adsorbents; the pipe sections each include multilayer pipes; the plurality of pipe sections are connected end to end; each of the pipe sections is coated with one adsorbent; and the adsorbent is coated onto the multilayer pipes of the pipe section. According to the present invention, the adsorbents are coated onto the pipes and supporting plates, so that heavy metals are separated in the wastewater conveying process, the area occupied by wastewater treatment facilities can be greatly reduced, and heavy metal ions in the wastewater can be efficiently separated.

A catch basin that configured to receive runoff water includes a first tube, a second tube, and a perforated cap. The first tube extends downward from an upper end to a lower end of the catch basin. The first tube has a first cross-sectional area that is defined along a first plane that extends horizontally though the first tube. The second tube extends horizontally outward from the lower end of the first tube at position that is below the upper end. The second tube is in fluid communication with the first tube and has a second cross-sectional area that is defined along a second plane that extends horizontally though the second tube, wherein the second cross-sectional area is greater than the first cross-sectional area. The perforated cap is secured to a horizontal end of the second tube.
