Sourcewell and HGACBuy are both real, active cooperative purchasing organizations that member agencies use to buy playground and recreation equipment without running their own competitive bid, but they are separate programs with separate contracts, separate vendor rosters, and separate renewal cycles.
What each one actually covers
Sourcewell runs a Playground and Recreational Equipment with Related Products contract, covering play structures, inclusive play components, and site amenities under one award. HGACBuy runs a separate Water Play and Splash Pad Equipment and Installation contract, specifically for water play systems, splash pads, pumps, and filtration, a distinct scope from general playground structures.
Why a dealer might need both
A dealer selling both dry playground structures and water play equipment is not covered by one contract for both product lines. Being awarded on Sourcewell's playground contract does not carry over to HGACBuy's water play contract, each requires its own separate award, its own vendor registration, and its own renewal tracking.
The practical takeaway
Map which cooperative actually covers each product line before assuming coverage, and register for both separately if both product categories are part of the business. Treating Sourcewell and HGACBuy as interchangeable is a common, costly assumption.
