  "abstract": "A catch basin for below-grade installations to receive water through a grate, and which can be adapted to receive and discharge water through a plurality of inlet ports, and be able to withstand heavy bearing loads without collapse of the basin or of its grate, especially one manufacturable by rotational molding.",
  "claims": [
    "1. A catch basin comprising a unitary single-piece body formed by a rotational molding process and having a substantially uniform wall thickness throughout, said catch basin comprising the following structural elements: a rectangular flat bottom; a first peripheral sidewall comprising a first band of four substantially flat first panels continuous with the bottom and with each other, said first panels having an upper edge; a second peripheral sidewall comprising a second band of four substantially flat second panels continuous with each other, said second panels each having an upper edge and a lower edge; a shoulder forming an inside step and an outside downwardly-facing overhang, the upper edges of the first panels and the lower edges of the second panels being continuous with said shoulder; a third peripheral sidewall comprising a third band of four third panels, and each said third panel having an upper edge and a lower edge, said upper edges of the second panels being continuous with the lower edges of the third panels, said lower edges of the third panels defining a downwardly extending pad at each side of the lower edges with a central portion of a lesser vertical dimension between said pads, said upper band having a greater length than said second panels, said pads thereby forming an inside step and an outside overhang, adjacent said pads being continuous with one another; and a peripheral collar continuous with said upper edges of said third panel, said collar having an outwardly extending shoulder, a peripheral upright band, an overhanging upwardly facing bearing surface, and an internal step, thereby forming an opening to receive a portion of a grate, and a bearing surface on which a portion of said grate can rest.",
    "2. A catch basin according to claim 1 in which an opening is formed in at least one of the second panels after said panel is formed, to receive a conduit.",
    "3. A catch basin according to claim 2 in which said opening includes key ways to engage keys on an engaging conduit.",
    "4. A catch basin according to claim 1 in which said step includes a downwardly extending termination flange."
