From the beginning, the city Department of Environmental Protection’s (DEP) federally-mandated Croton Water Filtration Plant has been unpopular and poorly executed.
But in 2008, three years into what could turn out to be a seven-year construction slog, things took another turn for the worse. The ever-swelling cost of the project broke the $3 billion mark, nearly tripling the DEP’s original cost estimate. Agency officials continue to say it’s due to skyrocketing construction costs.
But an analysis this fall by the city’s Independent Budget Office found that nearly half of the cost overruns couldn’t be accounted for by a rise in construction costs. Watchdogs believe (and the IBO suggested indirectly) much of the overruns are due to significant design changes and logistical challenges with doing the project in an eight-story hole in the ground. The DEP maintains its stance that the overruns couldn’t be avoided by building the plant somewhere else,
