Cranston, R.I. Veolia North America has served Cranston well since 1989, but through the landmark services agreement in 1997, the city transferred risk to Veolia and achieved even greater savings, improvements and efficiencies in its wastewater treatment system. This benchmark performance has resulted in numerous state and national awards.
In the late 1980s Cranston was under three separate consent orders and faced serious staff and maintenance problems as it prepared to upgrade its existing 23-MGD secondary wastewater treatment facility to a tertiary plant. The city contracted with Veolia in 1989 to provide full-service operations/maintenance/management (O&M) for the wastewater system and immediately began reaping the benefits of experienced leadership, technical expertise and staff training. The contract expanded in 1997 when Cranston selected Veolia to implement a 25-year lease transaction for the city's entire wastewater treatment system. An additional five-year extension, to 2027, totals a 38-year partnership.
