Abstract: A rainwater collection tank system employs a plurality of barrel/tanks, each having a plurality of strainers with a water pump for raising stored water to one or more faucet dispensers/spouts. Permanent tanks are at least partially submerged. Smaller portable units may be anchored to a campground area with screws and/or pins. Multiple units can be situated adjacent one another beneath a multi-sectional V-shaped funnel system of rain diverters.

Abstract: An outlet well cover for use in an in-line grease interceptor is disclosed. The outlet well cover is fitted onto a hollow well extending upwardly from the bottom of the grease interceptor tank, and having an open top. The outlet well cover has at least one, and preferably two arms that extend outwards and define water passageways from the ends of the arms to the middle of the well. Water inflow openings at the ends of the arms allow clarified water to flow into the covered hollow well. The water inflow openings face generally downward to limit the amount of floating FOG material that can be drawn in through the openings. The well cover may also include a central bore adapted to receive a standard sized pipe. The pipe can be connected to an outlet from the tank.

Abstract: A marine fuel backflow preventer and overfill alarm for use with marine vessels includes a housing provided for in-line installation in the fuel fill inlet line and directs fuel entering the a fuel filling inlet generally directly to a fuel filling outlet such that the fuel passes freely through the back flow preventer while being directed to the vessel fuel tank. The housing further functions as a reservoir for containing fuel which has accumulated therein due to over-filling and/or that has been carried into the housing via the fuel tank vent line. By providing a fuel containing reservoir disposed in-line the present invention thus functions to prevent unintended fuel spillage into the environment. The back flow preventer further includes an electro-mechanical float switch that automatically activates an alarm upon sensing the presence of fuel within the housing.

Abstract: An aircraft potable-water system (10) comprising an automatic valve (60) associated with an overflow line (50) and an automatic switch (70) associated with the storage tank (30). The switch (70) vents the storage tank (30) when it is not full, and automatically converts to a tank-pressurizing condition when the storage tank (30) is full. This conversion of the switch (70) causes the valve (60) to move to an overflow-open position so that excess potable water can be drained through the drainmast (18).

Abstract: A pipe structure of a windshield washer fluid feeding device for a vehicle includes a refill pipe which is used for the feeding of windshield washer fluid into a windshield washer fluid reservoir tank and has a multiply-curved form ensuring a sufficient working space between the refill pipe and a head lamp unit of the vehicle, and an auxiliary pipe connected at both ends thereof to certain portions of the refill pipe. With the combined configuration of the refill pipe and auxiliary pipe, even if the windshield washer fluid freezes, a joint region between the windshield washer fluid reservoir tank and the refill pipe is protected from damage.

Abstract: A unitary concrete structure pumping station useful in pumping waste fluids and the like during the passing of such materials from one part of a gravity flow waste system to another. This concrete structure is simple to install and use and many of the problems associated with conventional pumping stations are alleviated. The structure is comprised of several parts that can be made pre-assembled at the factory or assembled in the field prior to installation. By being a unitary structure this pumping station is resistant to movements within the earth and therefore less likely to incur line breaks.

Abstract: Apparatus and a method are aimed at reducing flood risk from stormwater draining from a property (1). The apparatus is adapted in use to retain stormwater at the property (1) releasing it from the property and comprises a container (6) which in use is located underneath or proximal to a building (2) of the property (1), and a control chamber (3) with which the container (6) is in fluid communication. The apparatus is operatively connected in use by at least one conduit (4) to drainage means (5) sourced externally from the building to receive stormwater into the container (6) by way of the control chamber (3), and is further operatively connected in use to at least a second conduit (7) to which stormwater exits from the container (6) by way of the control chamber (3). A level of stormwater in the control chamber (3) determines the inflow and outflow of stormwater into and from the container (6). Debris is prevented at the control chamber from entering into the container and passing to the second conduit (7).

Abstract: Apparatus and process for guiding portions of backwater produced or stored at different levels of a machine. The apparatus includes an upper backwater chamber arranged to receive first backwater, a lower backwater chamber arranged below the upper backwater chamber and to receive at least a portion of the first backwater from the upper backwater chamber. A plurality of hydraulic lines are arranged to couple the upper backwater chamber to the lower backwater chamber, and inlet openings of the plurality of hydraulic lines are arranged inside the upper backwater chamber and are arranged at different geodetic heights relative to one another. The process includes collecting first backwater in an upper backwater chamber, and guiding the first backwater from the upper backwater chamber to a lower backwater chamber through inlet openings to a plurality of hydraulic lines. The inlet openings are arranged at different geodetic heights relative to one another.
