A collector unit to be attached to a ceiling to collect leaking water and falling debris is formed by a sheet of water impervious material, preferably foldable and flexible, and having a generally concave shape with an outlet drain at a lower part. A net is fastened to the sheet across its open top. The unit is fastened to a ceiling and leaking water passes through the net, flows in the sheet to the outlet drain and it is conveyed away from the collector unit through a drain line connected to the outlet drain. Debris falling from the ceiling is caught by the net so that it does not reach the sheet and clog the outlet drain. The sheet and net are preferably of a material such that the collector unit can be folded into a package.
