Workers’ compensation coverage will be distributed through both Alteris’ and Zenith’s networks of insurance agents and brokers. Alteris will serve as the Insurance Administrator in order to facilitate the delivery of the workers’ compensation product to JPRIMA non-profit water systems and water-related entities located in California.

Key workers’ compensation class codes covered under CalMutuals JPRIMA will include Waterworks, Irrigation Drainage or Reclamation and Sanitary Operations.
