West Warwick Wastewater Treatment Plant West Warwick, R.I..

A 10.5 million gallon per day facility.

The West Warwick Regional Wastewater Treatment Plant is a 10.5 million gallon per day facility owned and operated by the Town of West Warwick. Its mission is to provide residents of West Warwick and neighboring communities with the most efficient and cost-effective services while maintaining the strictest standards of environmental awareness and conservation. In its capacity as a National Grid Project Expeditor, RISE Engineering conducted a no-cost energy assessment of the plant to identify recommended energy efficiency measures, which included upgrading 725 interior and exterior lighting fixtures and lamps. RISE managed the product acquisition and installation processes and coordinated with National Grid to leverage the utility's financial incentives.
