Providence Water (Scituate, RI)
In Fall 2009, Hart broke ground on the first substantial update to Rhode Island’s Philip J. Holton Purification Plant in over 40 years. Hart was awarded $50 million in construction contracts, implemented over eight years. With these new upgrades, the facility has continued to supply 60% of the state’s population with uninterrupted clean drinking water.
This project included the replacement of existing 18 filter beds with new, modern-design filters. The facility operated at total capacity while completing the re-build. All work was phased with only two filters allowed off-line at a time. Improvements also included the construction of new protective building enclosures covering the new filters, all new filter piping, valving and metering, and a complete upgrade of the plant’s process control and instrumentation systems.
