Philip J. Holton water purification plant (Providence, RI)

Philip J. Holton water purification plant (Providence, RI)

The Providence Water Supply Board retained CDR Maguire to evaluate, design, and provide construction services to effectively improve the operation and performance of the Holton plant. Originally built as a state-of-the-art facility in the 1920s, today the plant has a maximum capacity of 144 million gallons per day and remains the largest water treatment facility of its kind in New England.

Results included standardizing filter units to use dual-media sand and anthracite, a revised piping gallery configuration, improvements to various influent structures, and an upgrade to its carbon dioxide treatment system.

In addition, CDR Maguire, OʼBrien & Gere, and Process Research Solutions collaborated on two special water quality studies – a CO2 effectiveness study and an iron pipe study.
