LAKE DALLAS (CBSDFW.COM) – While a waste treatment plant operated by the Upper Trinity Regional Water District may sit just past city limits, the mayor of Lake Dallas says its odor knows no boundaries.

Mayor Tony Marino wants the City Council to vote on a resolution demanding the water district take action to curb the smell. It’s wafting into neighborhoods, he says, and its odor is often carried deep inside the city.

“Where it reaches tends to rely a lot on the wind direction,” Marino said. “But if you go by it almost on a daily basis you will smell the odor.”

The council will vote on the resolution during a meeting Wednesday. But Marino isn’t sure what the cost is or whether the odor originates from chemicals or somewhere else.

“I think it’s just going to be boiled down to using the right technology and probably the economics,” Marino said. “How much is it going to cost you to improve the technology and eliminate the smell?”

Marino said many residents have complained to the city about the smell. He also worries about the stench welcoming out-of-towners –– especially since it seems to be getting worse.

“The odor is pretty prevalent now,” he said, “it’s becoming more and more noticeable.”

The Upper Trinity Regional Water District wasn’t available to comment about the smell.
