It’s out with the old.

The Town of Hempstead is ditching its decades-old rusted and dilapidated water tower with a “state-of-the-art” replacement because it’s cheaper than giving it a facelift, officials announced this week.

Constructing a brand-new tower will cost just as much as maintaining the 70-year-old Uniondale tower — with an extra $1 million price for demolishing the 175-foot-tall beast.

“Just to redo an existing 70-year-old facility, it’s going to cost about $9 million, when to build a new one — state-of-the-art — is a little over [$10 million]. It really was a no-brainer on the investment,” Town Supervisor Donald X. Clavin Jr. said at a press conference Tuesday.

The project was mainly driven by residents’ longstanding concerns over the discolored and ugly water tower — which Calvin similarly slammed as “unsightly.”

There will also be financial advantages, he continued. The new tower will lay atop a reinforced concrete pedestal, meaning its steel supports will not be exposed to the elements, thus eliminating the issue of rust.

The old tower will remain standing until the new one is up and running, a process officials estimate will take roughly 18 months.

“So for maybe a year period, you’re going to see two water towers there, potentially,” Calvin said.

The news comes just weeks after town officials doubled down on plans to renovate the existing water tower, which holds 1.5 million gallons of water and primarily serves the East Meadow Water District.

When pressed about the tower’s dilapidated condition at a town board meeting last month, Hempstead Town Water Department Commissioner John Reinhardt said it would be rehabilitated “next winter, during the offseason,” Newsday reported.
