A water collection system integral to and providing structural support for structures such as roadways and buildings, designed to collect, filter, and store water such as stormwater runoff, segregated domestic waste (gray) water and segregated industrial water generated by said structures.
There are two additional functions that are components of this system. The first allows for the incorporation of both related and unrelated utility systems as an integral part of this system. Potential included utilities may include, but are not limited to, electrical conduits, telephone and telecommunications conduits, and the control system for a networked stormwater impoundment system.
The second additional function of this system allows for the use of the stored water as a source of heat capacitance for both domestic and industrial uses. For example, in a domestic situation the stored water could become the heat source for a water source heat pump. In an industrial situation the stored water could be used as a means to dissipate heat generated by industrial processes.
Why do I want to use this systemThe changing regulatory environment is moving towards a fee-based structure. Traditional management methodologies operate from a centralized stormwater and waste water treatment perspective. This system decentralizes the mitigation of stormwater and segregated waste water at the point of generation. It impounds this water and filters pollutants, thus meeting the changing regulatory objectives.
This system allows individuals, counties, municipalities, and other organizations, to benefit from the adaptability, or modular nature of this system. This system enhances the cost efficiencies of current stormwater, waste water, and utility infrastructure through the integration of these disparate systems. By adapting existing centralized stormwater systems and waster water systems, and installing this system to decentralize stormwater runoff and waste water treatment systems, both sources of water are more efficiently managed at the source.
Traditionally stormwater runoff in most parts of this country is diverted through the use of gutters and stormwater drainage piping to already taxed streams and channels, ultimately finding its way to the ocean, lakes, or man made detention basins. The “gray” water component of waste water is connected to the municipal sanitary system, where it is processed along with the rest of the components found in the sanitary sewer system.
The need for point of generation stormwater runoff management is critical given the increase in impermeable surfaces, particularly in urban environments. This system considers that urbanized areas and areas in which development has altered the natural hydrology and infiltration characteristics of the land typically experience increased surface runoff. Land development alters the natural balance between runoff and natural absorption areas by replacing them with greater amounts of impervious surface. This system addresses the reality of continued land development for urban centers and the need to mitigate the impact of such development.
Current stormwater management methods are limited in their ability to mitigate flooding and increased pollutant loads that are deposited by runoff during seasonal storms in oceans, lakes, and man made detention basins. Present methods have proved to be marginal in their impact or too costly. Compounding the problem is an alarming increase in stormwater pollution impacting drinking water and the environmental health of both urban and rural watersheds.
As noted above, gray water is simply processed as a component of the sanitary sewer system. The gray component of waste water is composed of water from sources such as kitchen and bathroom sinks, washing machines, and showers. This waste water can be processed in a manner different from that associated with traditional sanitary sewer system.
An objective of this system is to provide a water impoundment system that will collect, filter, and store stormwater runoff, gray water, and other sources of water using an integrated systems approach. This system enhances the existing utility infrastructure while mitigating the impact of untreated stormwater and gray water. This system provides residents, utilities and other organizations a viable way to treat these water sources, with the resultant water being capable of introduction back into the environment., where it can be used to replenish aquifers and lakes, or stored for uses that may include but are not limited to a source for irrigation water, heat capacitance, non-potable water uses, and/or fire suppression. Notably, this roadway application can also be used to mitigate pesticide and herbicidal pollution in agricultural areas.
Brief Summary of the System
The above system is achieved by use of a storage system that is integrated into the structure of a roadway or building. This system is composed of collection, filtering, storage and utility components. Each of the components can be expanded or contracted when installed to accommodate the specific needs of each site. This system is constructed in a manner best described as cellular. The cells in the structure are interconnected through the cells walls to create the noted subcomponents that impound, filter, and store water, and route utilities. Valves can be installed at the interconnection points to segregate or connect the various components.
Also, in this day of increasing requirement for technological infrastructure, this system can help to ensure that future technologies are more easily implemented. This capability for technology/utility bundling gives municipalities the advantage of selling the unused bundling space to public utilities, and telecommunications and digital service providers.
Filter units can be constructed to fit into the cells of the structure. Filter units are installed to mitigate specific pollutants at each installation site. This system’s ability to accommodate customized filtration solutions allows for the system to expand to accommodate the changing conditions relevant to the nature and regulation associated with stormwater runoff and gray water. Because of the adaptable nature of this system, devices such as monitoring equipment and pumps can also be installed in the cells of the structure, or appended onto the structure, or both.
In 1987 Congress amended the Clean Water Act to require EPA to establish phased National Pollutant Discharge Elimination System (NPDES) requirements for stormwater discharges. As a result, stormwater discharge permits have provided a mechanism for monitoring the discharge of pollutants to waters of the United States and for establishing appropriate controls. This system will support amended NPDES requirements for stormwater discharges.
The system can be integrated whole or in part in either new construction or as a retrofit to existing structures.
