The systems and methods herein are directed a wastewater management system which can be used on a housing unit. The wastewater management system includes a septic tank, pump tank, pressure tank, and pods residing within a drainfield.

A closed-loop system and method for heating of target contaminant zones having environmental contaminants of concern present in the groundwater and the soil by thermal conduction, and subsequent enhancements of physical, biological and chemical processes to attenuate, remove and degrade contaminants in the target contaminant treatment zones, is disclosed. The system and method collects solar or other heat and transfers the heat via a closed-loop and a set of borehole exchangers to subsurface soil in the proximity of and/or directly to the target contaminant treatment zones. The target contaminant treatment zone may comprise contaminated soil, contaminated groundwater in an aquifer, or industrial waste comprising water and/or solids. Solar collectors or heat exchangers capturing waste heat from industrial processes may be used as the heat source.

A horizontal-flow sand filtration pool and a water treatment process thereof. The horizontal-flow sand filtration pool includes a pool body, a raw water inlet assembly, a sand filtration bed, a filtered water outlet assembly, an aeration assembly, and a back washing assembly; the raw water inlet assembly includes a water inlet pipe and a water distribution device that supplies raw water to the sand filtration bed; the water inlet pipe is connected with the water distribution device, the water distribution device is provided in the sand filtration bed, and a plurality of water outlet channels are uniformly distributed on the vertical surface of the water distribution device; the filtered water outlet assembly includes a water collector and a water outlet pipe; the water outlet pipe is communicated with the water collector; the back washing assembly includes a back washing pipe and a drainage pipe.

A fluid management system including an inlet configured to receive pre-processed fluid is provided. The system includes a filtering apparatus configured to remove contaminants from the pre-processed fluid. The filtering apparatus includes a plate having a first opening. A first manifold pipe is disposed on the plate and includes one or more perforations and a second opening at least partially aligned with the first opening. A second manifold pipe is disposed on the plate and includes one or more perforations. Filter media is disposed between the first manifold pipe and the second manifold pipe and is configured to separate the contaminants from the pre-processed fluid. The system also includes an outlet coupled to the second manifold pipe to receive processed fluid from the filtering apparatus.

A surface water mitigation structure suitable for use in the storage and treatment of contaminated surface water runoff. The runoff is processed through a multi-layered filtration and treatment system wherein the first layer is one or more permeable layers that is pervious enough to allow liquid runoff to pass through it and into a porous storage medium second layer that includes one or more remediating agents, and wherein the effluent from the surface water mitigation structure can be discharged to the ground, the surface, and/or a drainage system reduced or free of contaminants.

A process for constructing a soil-based rhizosphere flow-through system to break down contaminants in contaminated water. The process includes the steps of: providing plants planted in soil in a test bioreactor, the plants providing a rhizosphere; exposing the rhizosphere to the contaminated water, extracting microorganisms from the rhizosphere following their exposure to the contaminated water: preparing a microbial suspension from the extract; subjecting the microbial suspension to growth conditions to increase the concentration of the microorganism, thereby preparing a soil conditioner; adding the soil conditioner to soil in a contained area having a water flow inlet and outlet; and planting a plurality of plants in the soil, the plants being of the same species as the plants of the test bioreactor.

A low-pressure distribution system configured to pressurize effluent and distribute it throughout pressure conduits disposed within drainage conduits. The low-pressure distribution system may pressurize the effluent such that it is dispersed along a substantial portion or the entirety of the length of the pressure conduits and/or drainage conduits. To that end, the low-pressure distribution system may ensure an efficient distribution of the effluent throughout the drainage conduits while retaining an effluent flow rate therein suitable for the growth of microbial water treating bacteria.

A stormwater treatment system and method for removing sediment, chemical pollutants, and debris from stormwater runoff by utilizing bioretention practices including physical, chemical and biological processes. Stormwater is directed into a primarily open-bottomed, multi-dimensional container whereby entrained sediment and other transportable materials are filtered and treated through a media filter layer consisting of inorganic and/or organic materials. A live plant (preferably a tree) situated within the container with roots resident in the media filter layer with the ability for expansion beyond the perimeter of the container through openings in one or more sidewalls. The treated water may be further conveyed beyond the perimeter of the container by additional openings and/or piping. A vertically positioned overflow/bypass/clean out piping apparatus may be included within the stormwater treatment system to provide additional water conveyance. Additional ancillary conveyance, filtration and storage facilities may be connected to the described stormwater treatment system as conditions warrant.
