A river course ecological treatment system essentially comprises a plurality of ecological biological water purification systems and a plurality of plastic retaining dams disposed along a river course, and at least one damp land ecological water purification system disposed beside the river course. The plastic retaining dams separate the river course into several retaining regions. The ecological biological water purification systems purify the water in the retaining regions by microorganism purification. Afterward, the water purified by the ecological biological water purification systems is introduced into rainwater channels of the at least one damp land ecological water purification system. After being purified by aquatic plants in the at least one damp land ecological water purification system, the water returns to the retaining regions the downstream portion of the river course. Therefore, a river improvement system capable of performing both step-by-step treatment and joint treatment is effectuated.

Disclosed are a method, device and system of a watershed stormwater management through a biobased biodegradable nutrient and sediment retaining water filtration tube with erosion control. In one aspect, a method of watershed stormwater management system includes forming the biobased filtration tube from a nontoxic renewable domestic agricultural material. The method ensures a diameter of the biobased filtration tube to approximately 10% greater than a field deployment to prevent shrinkage caused by ambient conditions, retains a sedimentary pollutant, and places the biobased filtration tube along the perimeter of a site. A filter material of the biobased filtration tube helps preventing high concentrations of sedimentary pollutant from getting into the streams. The biobased filtration tube captures and treats stormwater that runs off as sheet flow. The biobased filtration tube is utilized in the vegetated form. Vegetation grew into a slope at the site anchors the biobased filtration tube in an environment.

A distributed utility system includes water source supply lines capable of being placed in fluid communication with a separate water source, water discharge lines capable of being placed in fluid communication with a separate water discharge destination, a water source and destination control manifold to allow selected water source supply lines to be placed in fluid communication with selected water discharge lines, and a storm water collection and distribution system. The storm water system includes a storm water collection conduit and a collected storm water discharge line in fluid communication with the storm water collection conduit, and the storm water discharge line can be placed in fluid communication with the plurality of water discharge lines via the control manifold.

A system designed to control and filter runoff water in storm drains is presented. Drain water frequently carries trash, organic matter, suspended solids, hydrocarbons, metals, nutrients and bacteria collected from streets and parking lots into a storm drain inlet, which enters storm water drain pipe systems.

The present invention supplies a series of baffle boxes inserted in the drain water stream with a final box possessing an upflow filter comprising filtration media and filter cartridges. The system can also support a storm flow bypass that directs high-flow storm runoff water directly to the outlet to protect the filter system.

Disclosed is a system for managing water. In example embodiments, the system may include a long pond for storing water. In some embodiments the long pond may be used to prevent flooding, in other examples the long pond may be used as a reservoir for holding water usable with irrigation and sub-irrigation systems.

The invention is directed towards decoupling tidal effects from time-series depth measurements. A drainage sensor includes a fluid depth sensor. The drainage sensors are positioned at monitoring points in a drainage system. Stormwater flows into an input of the drainage system. A tidal depth sensor is positioned in a tidal body of water near an output of the drainage system. During period of high tide, tidal water backflows into the output of the drainage system. The decoupling is accomplished by generating a model of tidal backflow patterns based on data from the drainage sensors and the tidal sensor. The model accounts for a lag time between the tidal data measurements and measurements of the drainage sensors. The model is be used to predict the contribution of tidal backflow effects to stormwater data.

A FES assembly for use with a drainage pip is described herein. The FES assembly includes an inlet head wall portion, a tapered midsection coupled to the flared end portion, the tapered midsection extending from the inlet head wall portion to a flared end section. The inlet head wall portion defining a base wall spacing and coupling first and second lateral walls, a partially circular portion defined by the first and second lateral walls, and a coupling base portion extending along the base wall. First and second folding hinge arms are hingedly coupled to the first and second lateral walls, wherein the first and second folding hinge arms define first and second arced surfaces. The first and second hinge arms extend between an open position and a closed position, wherein in the closed position, the first and second arced surface align with the partially circular portion to define a portion of a circle greater than the partially circular portion.
