The present invention provides improved diverter assemblies (10) designed for installation on liquid-conveying conduit sections (12) having one or more joints susceptible to leakage of liquid. The assemblies (10) include a plurality of mating housing sections (34, 36) which are releasably interconnected and in surrounding relationship to the conduit sections (12) on opposite sides of the conduit joint(s) to form an overall housing (35) defining anon-sealed enclosure. The housing (35) is equipped with a sump (72) which gravitationally collects escaped liquid. The sump (72) includes a drain outlet (74) for conveying the collected liquid away from the conduit sections (12) for collection or reuse.
