A sump overflow protection system for use in a building having a floor and a drainage field for collecting water from the perimeter of the building. The sump overflow protection system includes a portion of the floor proximal an opening of a sump crock having a first level defining a base and wherein the rest of the bottom floor generally has a second level higher than the first level of the basin surface of the floor and communicates water overflowing the sump crock to an outlet coupled to a building drainage outlet separate from the sump crock and to be located in the basin surface of the floor and spaced a predetermined distance from the sump crock.

Various aspects of the present disclosure are directed to methods and systems for in-situ accumulation of one or more substances from a liquid environment. In one embodiment of the present disclosure, a method is disclosed including placing a cartridge with a sorbent in the liquid environment, driving a liquid volume through the sorbent, and repeating the act of driving as a function of time.

A system is provided for tracking, in a distributed water infrastructure, water usage by category. The system may comprise at least one processor configured to receive from at least one sensor associated with the distributed water infrastructure signals indicative of water usage in the distributed water infrastructure. The system may, based on the signals indicative of water usage, construct a plurality of profiles. The system may assign each profile to one of a plurality of water usage categories. The system may collect, from the at least one sensor, signals indicative of water usage for substantially all water delivered through the distributed water infrastructure in a time period. The system may construct a plurality of water usage profiles in the aggregate, encompassing substantially all water delivered through the distributed water infrastructure in the time period. The system may assign each constructed water usage profile to one of the plurality of water usage categories. The system may output, for display, water usage for the time period for each of the plurality of water usage categories.

The present invention discloses a filtration system for treating untreated liquid such as greywater or any liquid that is contaminated with impurity and is required to be treated before use. The filtration system is a gravity fed liquid treatment system and includes components such as a top liquid tank for holding untreated liquid and a bottom liquid tank for holding treated liquid. The filtration system further includes one or more filtration media containers and filtration columns. Each filtration column is a composition of the stacked filtration media containers. The filtration system may be used for cleaning the contaminated water or keeping clear the surface of open water from oil or the like floating materials by separating or removing these materials from the water. The filtration system may include portable or detachable small-scale multistage treatment devices and may be implemented using household-type filters for producing potable filtration system.

A system and method for controlling microbiological growth in a water system and premise plumbing system which uses stabilized hydrogen peroxide as a disinfectant and maintains water energy matrix control. Maintenance of stable hydrogen peroxide residual in the system in combination with active temperature monitoring enables better control of the water energy matrix and reduction of hot water temperature while maintaining microbiological control.

A fluorometer is provided for monitoring the quality of water, featuring an array of excitation sources, an array of multiple emission detectors and a signal processor. In the array of excitation sources, each excitation source provides respective excitation source optical signaling at a respective illuminating wavelength. The array of multiple emission detectors detects multiple emission wavelengths emitted from water containing information about multiple coexisting fluorescent species present in the water that emit optical radiation at at least two different wavelengths when illuminated by the respective illuminating wavelength provided from the array of excitation sources, and provide multiple emission detector signaling containing information about the multiple coexisting fluorescent species. The signal processor receives the multiple emission detector signaling, and determines corresponding signaling containing information about an identification of the multiple coexisting fluorescent species present in the water using a near-simultaneous identification technique, based upon the multiple emission detector signaling received.

The invention provides a sampling device for geological fluid detection, relates to the technical field of fluid detection. The sampling device comprises a support frame, the support frame is of an L-shaped structure, and a second support plate is arranged above the support frame; the protection cover is mounted at the corner of the bottom of the support frame. The water fixing cone is clamped above the support frame; the locking inclined block is mounted at the upper part; and the detector is provided with a water inlet pipe. Fluid at different depths is detected through cooperation of the mounting sleeve and the lifting frame, a fluid drainage tube is wound through the winding wheel, the mounting sleeve is driven by the lifting frame to adjust the position through the arrangement of the gear and the rack, the fluid is sampled through the sampling test tube.

Sampling devices for sampling an aqueous source (e.g., field testing of ground water) for multiple different analytes are described. Devices include a solid phase extraction component for retention of a wide variety of targeted analytes. Devices include analyte derivatization capability for improved extraction of targeted analytes. Thus, a single device can be utilized to examine a sample source for a wide variety of analytes. Devices also include an isotope dilution capability that can prevent error introduction to the sample analysis and can correct for sample loss and degradation from the point of sampling until analysis as well as correction for incomplete or poor derivatization reactions. The devices can be field-deployable and rechargeable.

An inspection apparatus includes a stirring/mixing means for stirring and mixing a sample solution in a batch-type sample container, an excitation light source including a light source that irradiates an irradiation plane of the sample container in the vertical direction, a light-receiving means arranged on the lateral face side of the sample container, and a control means for calculating the number of microorganisms contained in a sample in the sample solution.
