Energy from the sun is like money in the bank for the wastewater treatment plant in La Porte.

The plant started running on solar energy last summer.

Wastewater superintendent Jerry Jackson says enough energy is produced to sometimes to run

the entire plant. He said there’s about a $15,000 a month saving on the energy bill at the plant.

Jackson says it should take about 12 years for the investment to pay for itself from the

energy savings.
