Service Area Improvements Study; 50-Year Population and Water Use Study; Capital Efficiency Plan™, SCCRWA

Tata & Howard provided engineering services and completed numerous studies for the South Central Regional Water Authority (SCCRWA) headquartered in New Haven, Connecticut, serving 17 Cities and Towns and serving a population of over 400,000 people. Phase 1 of the New Haven Service Area Improvements Study was completed in 2009. The purpose of the study was to determine the lowest cost set of recommended capital and operational improvements to incorporate additional service areas into the New Haven Service Area.  Our services included evaluating potential improvements to the distribution system to meet SCCRWA’s pressure, tank fluctuation, and fire flow criteria, and recommending a conceptual baseline solution, which was optimized during Phase 2 of the study.  Phase 3, which completed the study, included a Preliminary Design Report with our final recommendations.

A 50-Year Population and Water Use Study was completed for SCCRWA in 2009.  The study examined trends in water use and population growth in each of the towns and service areas served by SCCRWA and projected future water use for average day, maximum day, and maximum month demand throughout the distribution system.  The projections were completed in accordance with guidelines from the Connecticut Department of Public Health and were involved in SCCRWA’s 2009 water supply plan.

In 2008, SCCRWA purchased a water distribution system with approximately 125 miles of water mains and customers located in Ansonia, Derby and Seymour, Connecticut. Tata & Howard was contracted to complete a Capital Efficiency Plan™ of the new system. Our services included updating and verifying the existing hydraulic model, evaluating the condition of the existing distribution system infrastructure to determine the adequacy of meeting present and future demands, calculating needed storage requirements, assess and prioritizing system improvements, reviewing and evaluating typical fire flows throughout the system, creating a pipe asset management rating system, and recommending improvements to the distribution system. Following the success of this effort, Tata & Howard completed Capital Efficiency Plans for the
remainder of the distribution system in 2011 and 2012.
