Clifton Park, New York

In 1991, C.T. Male Associates was selected by the Clifton Park Water Authority (CPWA) to plan and engineer the consolidation and improvement of six separate private water systems operating within the Town into a single town-wide system.  By consolidating separate water systems into one district, the CPWA was able to ensure that quality water continued to be available to current and future residents at affordable rates.  Users of the consolidated district benefit from economies of scale when maintenance and management operations are combined.  Under a quasi-public body, district managers are accountable to the public and charged with serving the public interest.  Residents have opportunities to provide input into operating policies and future expansions.

As an engineer for this project, C.T. Male Associates surveyed the area encompassed by the individual systems, valued their infrastructure components and advised the owner on their purchase and prepared engineering studies in support of a $21,675,000 revenue bond issue in 1991 used for system acquisition and improvements.  Hydraulic computer modeling was used to evaluate the existing systems and to design interconnections and improvements for an integrated system.  The consolidated system includes over 160 miles of pipe and over 20 production wells.  The system modeled had over 900 nodes.  Higher water storage elevations imposed on some areas required the reevaluation of the adequacy of well and booster pumps.  The model allowed the evaluation of both existing and improved conditions so that optimized operation of the system was possible as the phases of the capital improvement program were completed. Since the original bond issuance, C.T. Male Associates provided engineering services for additional bonding for capital improvements (two times) and for bond refinancing (four times) that reduced the cost of debt without extending the term of the bond.

Originally, C.T. Male Associates designed a number of capital improvements which were necessary to physically combine 6 individual systems into one water network, including well rehabilitation, new wells, 2 new water storage tanks, 75,000 feet of 12″ – 24″ transmission mains, PRV stations, system interconnections, two iron and manganese treatment plants, and booster pump stations.  C.T. Male also advised the Authority on budgeting, rate structure, management and operating techniques to facilitate a smooth transition into a public system.  The cost of infrastructure improvements made as part of the consolidation and system expansion exceeded ten million dollars through 2000.

Since 2000, C.T. Male Associates has designed additional improvements to, and expansions of, the system, including over 21,000 feet of 12” to 16” transmission mains; four interconnections to three adjoining water systems;  the rehabilitation of two water storage tanks that included lead paint removal; engineering assistance to incorporate three additional water systems into the system;  well pump replacements; and treatment upgrades at several sources of supply.
