An urban transformation and construction method is disclosed that creates a tropical style swimming lagoon at vacant and/or abandoned sites. The transformation includes demolishing at least part of the vacant or abandoned site, excavating material from within the site; forming a basin for a large water body having a surface area of at least 3,000 m2, and constructing water containment walls on a first section of the basin to form a waterfront perimeter. The shape of the waterfront perimeter is mainly curved, the basin has a maximum width of 300 meters, and the bottom is covered with a non-permeable material. A sloped access area is constructed in a second section of the basin to form a beach. A barrier is constructed to control access into the area including the beach. At least one recreational facility is constructed including restaurants, bars, kiosks, stores, and/or cafes about the waterfront perimeter.

An above-ground pool is provided and includes a pool bottom and a pool wall, together defining a water storage space. The pool bottom includes a lower bottom sheet connected to the pool wall and an upper bottom sheet, the upper and lower bottom sheets connected in a ring region defining a sandwich region within the ring region. A porous elastic material is disposed between the upper bottom sheet and the lower bottom sheet in the sandwich region. A water drainage device includes a water drainage valve and a water drainage pipe, and the water drainage valve penetrating through the pool bottom and connected to the water drainage pipe beneath the pool bottom. A vent hole through the lower bottom sheet in the sandwich region provides communication between the porous elastic material and an environment external to the pool. The vent hole is disposed in a region of the pool bottom which is lifted off an external surface by the water drainage pipe beneath the pool bottom.

A drainage device for an above-ground pool, and an above-ground pool including the drainage device are provided. The drainage device includes a drainage pipe, with inlet and outlet ends, and a drainage valve connected to the inlet end of the drainage pipe. The drainage valve includes a water inlet periphery, defining a water inlet in fluid communication with the inlet end of the drainage pipe, and a connecting member disposed circumferentially around the water inlet periphery. The connecting member is radially spaced apart from the water inlet periphery. The connecting member may be formed by injection molding around the water inlet periphery.

A water faucet includes a first pipe, a housing and a first sealing ring. The first pipe includes a first sidewall, a second sidewall, a third sidewall and a first sliding portion. The first pipe includes a first accommodate space and an inlet. The housing includes a top wall, a second pipe and a second sliding portion corresponding to the first sliding portion. The second pipe includes a fourth sidewall connected with the top wall to form a second accommodate space and an outlet. When the first sliding portion slides to a first position, the first sealing ring is located between the fourth and the second sidewall to prevent water flowing between the first pipe and the housing. When the first sliding portion slides to a second position, water from the inlet can flow to the outlet via the first accommodate space, the though hole and the second accommodate space.

A wave generation assembly for producing a wave in a pool for surfing includes a below ground pool that is filled with water. A boat hull is integrated into the below ground pool and the boat hull is partially submerged in the water contained in the below ground pool. An outlet jet is coupled to the boat hull such that the outlet jet is submerged in the water. A propulsion unit is integrated into the boat hull and the propulsion unit is in fluid communication with the outlet jet. The propulsion unit urges the water outwardly through the outlet jet at a velocity sufficient to generate a wave in the water which extends away from the boat hull. In this way the outlet jet facilitates the user to surf on the wave generated by the outlet jet.

Kit including prefabricated components for erecting a prefabricated water containment structure. The kit includes all parts necessary for erecting a prefabricated water feature or containment enclosure. The kit includes a prefabricated three-inch structural steel channel of various lengths, steel support struts, corner sections, steel corner support gussets, a centre steel support band, eight steel attachment plates, four airplane cord channel joining devices, concrete board inner and outer wall panels, containing all the necessary cut-outs to accommodate prefabricated plumbing and electrical assemblies. The kit further includes rivets, stainless steel bolts, lock washers and nuts. The kit includes a prefabricated submersible hollow concrete water pump pedestal for water containment structures. The kit also includes all the required piping and wiring needed to connect plumbing and electrical assemblies to external sources. The kit helps homeowners, residential and commercial builders, landscape architects for constructing a water feature, fountain base, or water reservoir.

A swimming pool wall, and method for forming same, including a plurality of layers of reinforced composite material. Each layer includes a thermoplastic resin and a plurality of elongate glass strands of reinforcing material. A first set of the plurality of layers has the strands running in a first direction, and a second set of the plurality of layers has the strands running in a second direction. The first direction is offset in angle from the second direction, and the first and second set of layers are fused together to form a unitary composite wall. The pool wall permits the use of a composite material which provides sufficient strength and resists degradation. The wall structure may be a plurality of interconnected panels both arcuate and arcuate and planar in shape to determine the overall shape of the composite wall enclosing an area where water or ice is retained.

An above ground frame pool (10) includes a frame assembly (20) and a liner (40) supported by the frame assembly (20). The frame assembly (20) includes a plurality of horizontal pipes (22), a plurality of vertical pipes (24), and a plurality of T-shaped joints (30). The joints (30) may lack mechanical fasteners with adjacent pipes or corresponding apertures. The joints (30) may be one-piece or multi-piece structures. Such joints (30) maybe water-resistant and convenient to manufacture, assemble, disassemble, and store.

There is disclosed a spa. The spa generally having a unibody shell having a basin, a rim portion surrounding the basin, a peripheral wall extending from the rim portion, and at least one opening in the peripheral wall, the basin, the rim portion and the peripheral wall defining a cavity therebetween, the at least one opening exposing the cavity; and a frame structurally mounted within the cavity, the frame having a crossbar and a plurality of strut members extending from the crossbar, the crossbar and the plurality of strut members running along respective sides of the at least one opening, the plurality of strut members each being affixed to the unibody shell at locations distributed about the at least one opening.
