Waste fluid holding tank drain system and method
09908122 · 2018-03-06 · ·

A waste fluid containment and draining system may have a black waste water holding structure for holding black waste water and a grey waste water holding structure for holding grey waste water. First and second valves may be included for enabling selective emptying of the two holding structures. A macerator pump may be used which has an input in flow communication with both of the first and second valves. A discharge conduit may be in flow communication with an output of the macerator pump. A control subsystem may be in communication with the first and second valves and the macerator pump for controlling the first and second valves, together with the macerator pump, to enable selective pumping out of the holding structures by the macerator pump through the discharge conduit.

RAINWATER RESERVOIR

An insert (400) for a rainwater downpipe (300) is fluidly coupled between a first section (310) and a second section (320) of the rainwater downpipe (300). A rainwater reservoir (500) is defined within the insert (400) to store the rainwater received from the first section (310) therein. The rainwater reservoir (500) includes a side surface (510), a bottom surface (520) and an outlet opening (522) fluidly coupled to the second section (320). A valve element (530) is disposed within the rainwater reservoir (500) to allow or deny the passage of the stored rainwater in the rainwater reservoir (500) through the outlet opening (522). The insert (400) is characterized in that the side surface (510) of the rainwater reservoir (500) further defines a rainwater harvesting opening (549) adapted to allow access to the rainwater stored in the rainwater reservoir (500).

Systems and methods for water re-use

A water use management system may be installed in a setting that contains a primary infrastructure for water use to provide an alternate, modular infrastructure for water use. Fresh water used at various points of use, such as a shower or sink, may be diverted into the modular infrastructure prior to draining into the primary infrastructure. Once diverted, the precedent use water is received at a reservoir system where it is treated for a subsequent use. Treatment may include filtration and/or chemical treatment, and may be based upon sensor feedback from the reservoir system. Once treated, the water is ready for subsequent use and may flow from the reservoir system, via the modular infrastructure, to a subsequent point of use, such as a toilet.

Waste and/or Hazardous Liquid Containment and Collection System
20170183859 · 2017-06-29 ·

5 A liquid cleaning system rests on a surface having a non-porous material covering and a drain. A lower plate layer and an upper plate layer each have runners arranged in a grid. The lower plate layer rests upon the surface and the upper plate layer rests upon the lower plate layer offset at an angle with respect to the grid of the lower plate layer.

An upper layer covers the upper plate layer and has a plurality of holes for the passage of fluids into the liquid cleaning system. As liquid enters the liquid cleaning system through the holes, the liquid traverses the grid of the lower plate layer and the grid of the upper plate layer flowing towards the drain, and contaminants within the liquid collect within the grid of the lower plate layer and the grid of the upper plate layer.

GATE VALVE DOWNSPOUT DIVERTER FOR RAINWATER COLLECTION
20170002550 · 2017-01-05 ·

A downspout diverter for rainwater collection that consists of a rotating diverter unit with a catchment gate that captures and redirects the flow of water to the outside of the downspout when it is turned to its horizontal upright position, and restores downflow when it is turned to its vertical open position. The device is easy to install and remove without disconnecting the downspout, and the small size of its port and fixtures effects a finished appearance to the downspout.

WASTE-WATER DIVERTER

A waste water diverter may have a housing, which encloses a cavity, a waste water inlet arranged at an upper end of the housing and opening into the cavity. The diverter may also have a grey water outlet and a black water outlet, which are connected to the cavity, and arranged at a lower end of the housing. A guide plate may be arranged in the cavity to be pivotable about an axis of rotation between a first position and a second position via a drive such that waste water flowing in through the waste water inlet is guided by the guide plate in the first position into the grey water outlet and the black water outlet is blocked, and in the second position the grey water outlet is blocked by the guide plate and the waste water is guided into the black water outlet.
