Abstract: A pool perimeter assembly extending along a portion of a pool perimeter includes a combined gutter assembly having a gutter conduit and a grate supported above the gutter conduit. The combined gutter assembly also has a partition dividing the gutter conduit to form an exhaust air plenum on one side of the partition. A surge tank is fluidly connected to through a modified converter box and a water-air line to the exhaust air plenum. An exhaust fan is connected to the surge tank and generates below atmospheric pressure so that the contaminated air on the pool surface is drawn through the grate and into the exhaust air plenum, through the water-air line, into the surge tank, and of the surge tank through the exhaust fan.

Abstract: An agitator system for a diving station that directs water flow from the perimeter of a pool onto a water surface of the pool, where the agitator system is connected to a pool perimeter assembly having a return conduit for receiving pressurized water, and the return conduit has at least one return outlet, includes a spray port and a fluid delivery system. The spray port is located on the pool perimeter assembly and is configured for directing a water spray onto the water surface of the pool. The fluid delivery structure is in downstream fluid communication from the return conduit and in upstream fluid communication with the spray port. A first portion of the pressurized water in the return conduit is communicated to the spray port via the fluid delivery structure, and a second portion of the pressurized water is delivered to the return outlet for dispersing to the pool.

Abstract: A pool perimeter assembly includes conduits extending between the sidewalls, wherein the conduits are separated by a common wall between the sidewalls. A grate is positioned on the gutter apparatus to direct fluid flow into at least one of the conduits. The fluid flow may include water or air. A first length of the perimeter assembly includes conduits defining a gutter trough and an extra gutter, and the common wall defines a common opening between the conduits. A second length of the assembly includes two conduits defining a gutter trough conduit and an air evacuator conduit separated by a section of the common wall without the common opening. The evacuator conduit is connected to an air exhaust system to remove water vapor and contaminated air from the area surrounding the pool.

Abstract: A pool perimeter assembly includes conduits extending between the sidewalls, wherein the conduits are separated by a common wall between the sidewalls. A grate is positioned on the gutter apparatus to direct fluid flow into at least one of the conduits. The fluid flow may include water or air. The grate is so dimensioned relative to the gutter apparatus so as to fit within a grate fitting device connected to the gutter assembly. The grate fitting device is a grate angle having at least a riser and a lip. The grate angle may include a welding base used in up-fitting existing pool structures to accommodate new grates.
