This is green technology? No offense meant to those trying to package this as green technology, this is just common sense and nothing new. The Romans built the aqueducts which were all gravity fed centuries ago. I have to wonder why the MUA hasn't done this before.

That's a 15+ year simple payback, which is pretty poor.

Did a new aqueduct need to built anyway? If so then this program makes sense. If not.. then not so much.

New $5.8M water pipeline operational, part of Jersey City's push for green technology

As Jersey City continues to incorporate more green technology, an innovative, cost-saving water pipeline that relies on gravity to flow water is now operational.

Completed in June, the $5.76 million pipeline will use gravity to bring water from the Boonton Reservoir Dam -- the major source of water for Jersey City residents -- to a treatment facility. This new method is expected to save the city $375,000 annually in electricity costs, officials said in a press release.

"This public/private partnership is a great example of an innovation project that reduces our carbon footprint, while lowering operational costs," Jersey City Mayor Steve Fulop said the press release.
