Systems and methods for intensive recirculating aquaculture are provided herein. An example system includes water sourced from a first segment of a saline aquifer, a recirculating aquaculture system receiving the sourced water and producing discharge water, and a water discharge point located within a second segment of the saline aquifer disposed below the first segment of the saline aquifer.

An intelligent sewage system designed for use in municipalities around the Wildland Urban Interface incorporates a decentralized network of wastewater treatment units to process wastewater from a plurality of parcels. The decentralized wastewater treatment units spread a Biological Oxygen Demand (BOD) reduction of the wastewater throughout the system and effluent is delivered efficiently through a pressure sewage system. Non-potable and potable water supplies are generated and delivered to individually separable water distribution zones throughout the municipality. The system also provides an auxiliary high-pressure, high-flow non-potable water supply to compensate during depressurization events and bolster the water distribution zones in the event of a wildfire emergency event. The intelligent sewage system also incorporates a comprehensive wildfire defense network and a supervisory control and data acquisition system which work in concert to harden the municipality against wildfire risks and combat active wildfires.

The invention relates to a method and apparatus for treating water. Iron is removed biologically from humus-rich water with the solution according to the invention. In the method, the water being treated is conveyed through a filter, which filter comprises filter material. Before the water is conveyed to the filter, the pH value of the water is lowered with an acidification part that is included in the apparatus.

The invention provides structures, methods, and assemblies for bioretention systems, including tree box filters with one or more internal bypass features incorporated into the tree box filter. The invention also provides methods and additional structures that are useful for managing stormwater flow and inhibiting the flow of pollutants, debris, and other contaminants into drainage systems.

The present disclosure provides a deepwater cabin-based constructed wetland treatment system, including a cabin body, water inlet subsystems, a drainage subsystem, a micro-aeration subsystem, and a filtering scrapper subsystem. The micro-aeration subsystem includes a micro-porous aeration pipe and an air blower. The cabin body is filled with combined filler. The micro-porous aeration pipe is arranged at a bottom of the cabin body. The filtering scrapper subsystem is arranged above the combined filler. The water inlet subsystems are used for introducing wastewater to be purified onto the filtering scrapper subsystem. The filtering scrapper subsystem is used for performing filtering treatment on the wastewater to be purified to obtain filtered impurities and water after primary filtering, transporting the filtered impurities to a specified area, and introducing the water after the primary filtering onto the combined filler.

Systems and methods of restoring a lake including dredging, island creation, water treatment, real estate development, computer modeling of environmental conditions, wave height reduction, sediment removal and encapsulation, bathymetry contouring, littoral zone restoration, plant restoration, and/or fish restoration.

A system for transferring marine life within an aquaculture facility including a plurality of segregated storage facilities each containing water for marine life, maintained within a predetermined temperature range and supported at independent ground levels. The storage facilities are successively disposed and structured to contain marine life at different stages of growth. A transfer assembly includes a path of fluid flow interconnecting successive ones of said plurality of storage facilities in fluid communication with one another, wherein at least a majority of a length of said path of fluid flow is disposed beneath the independent ground levels at a predetermined depth, which is sufficient to facilitate maintenance of the path of fluid flow within the predetermined temperature range, via geothermal cooling.
