1. A drain box assembly for a convertible splash pad/ice rink structure having a plurality of in-ground coolant pipes, said drain box assembly comprising: a housing having an open top and a bottom portion, a water ingress port formed by the open top of the housing and a water egress port in the bottom portion of the housing, with one or more upright walls connecting the open top and bottom portion of the housing in fluid sealing relation to form within the housing a vertically directed water flow channel connecting said water ingress port and said water egress port in fluid communication with each other; at least one connector mounted on said housing for operatively securing said housing at said water egress port to a drain pipe installed in the ground; and, a plurality of coolant pipe segments, each coolant pipe segment having a first open end and a second open end connected such that the first open end and the second open end are in fluid communication with each other to define for each coolant pipe segment an axis of symmetry extending between said first open end and said second open end; said plurality of coolant pipe segments each being mounted on said housing so as to extend across the housing adjacent the open top and through said vertically directed water flow channel, in transverse relation to said vertical water flow channel, with the first and second open ends of each coolant pipe segment extending beyond said one or more upright walls; wherein, when the convertible splash pad/ice rink is used as an ice rink, said plurality of coolant pipe segments contain coolant to provide cooling of the open top of the drain box assembly.
