A toilet flap valve assembly includes a band that is comprised of a resiliently bendable material thereby facilitating the band to be formed into a closed loop that is positionable in a trap of a toilet bowl. A flap is movably attachable to the band when the band is formed into the closed loop. The flap is foraminous to pass liquid therethrough and the flap is normally positioned in a closed position having the flap closing the closed loop. The flap is only openable in a direction of flow in the trap to inhibit an animal from entering the toilet from a sewer line. The flap is urgeable into an open position in the direction of flow in the trap to facilitate solid waste to flow through the trap when the toilet is flushed.

An apparatus for holding a bait for rodents, the apparatus has a housing, a bait platform in the housing, and a passage opening for rodents to access the bait platform. The apparatus can be inserted into a manhole.

Barrier (1) for being installed at least partly within a sewage pipe, wherein said barrier (1) comprises two support wings (4) forming an outer shell of said barrier, one or more shutters (6), at least one shutter guide mechanism (7), and a mounting tube (8), and wherein said barrier (1) having a pipe shaped outer shell installable in the sewage pipe, and said barrier having a longitudinal axis X along said pipe shaped outer shell, wherein said shutter (6) is partly covered by said support wings (4), and wherein said support wings (4) are placed along the longitudinal axis X, wherein said support wings (4) are adapted to pivot about a wing hinge (10) positioned on a frame housing (9) of said barrier, wherein said barrier is adapted for having said shutter (6) capable of pivoting about a shutter hinge (15) provided in said frame housing (9) of said barrier, where said shutter (6) having a closed position and a more or less open position, where the shutter (6) is capable of pivoting from a substantially vertical closed position to an angular open position away from vertical in one direction along the longitudinal axis X, where said shutter guide mechanism (7) is capable of controlling said shutter movement direction from a first direction to a second direction opposite to the first direction, along the longitudinal axis X, and furthermore said shutter guide mechanism is capable of adjusting a shutter kip angle a, where shutter kip angle a is the angle from the shutters vertical closing position to maximum angular opening position, and said shutter guide mechanism (7) being capable of preventing the shutter to move in the respective opposite direction to the first or second direction along the longitudinal axis X.

A rodent deterrent system for a pipe system, the pipe system including a T-junction and a midsection riser. The deterrent system for the T-junction includes a first mesh screen configured to surround a vertical portion of the T-junction and a second mesh screen configured to surround a horizontal portion of the T-junction. Also, the deterrent system for a perforated riser includes a mesh wrap sleeve configured to surround the midsection of the riser. Alternatively, the riser midsection sleeve can be lengthened so that the second mesh is not needed as the lengthened sleeve also performs the same function as the second screen.

A removable catch basin filter insert includes a filter container is fitted into a catch basin in the ground at the location where the stormwater exits the gutter and enters the stormwater sewer system. The removable catch basin filter provides pollution capture from stormwater while being easily cleaned. A hinged cover is included at the top of the filter insert to allow the captured pollutants to be evacuated through the use of a vehicle or being tipped nearly upside down by a mechanical arm. A hinged trap door is included at the bottom of the filter insert to allow captured pollutants to be evacuated through the bottom of the device and into a container. By capturing the pollutants with the removable catch basin filter insert before the pollutants enter the mainline storm drain system, clean storm drain systems are provided allowing for cleaner waterways.

The present invention provides an in-line valve particularly suitable for draining facilities to avoid odour penetrating habitable spaces or backflush of drainage liquids. The in-line valve comprises a body, preferably made of two engageable parts, an inset and a duckbill valve. The insert is located within the valve body and surrounding the duckbill valve. The insert funnels liquid from the valve inlet to the valve outlet, so that puddling in the valve body is avoided and therefore no water is accumulated, which could lead to odours or microorganisms proliferation.
