It's only begun to get really hot so you'll need to make sure you water your lawn properly this summer to help keep it healthy.

SUEZ Water Company is trying to help you out too by offering a complimentary lawn watering education program, 'Evapotranspiration' for customers in South Jersey.

This will help measure water loss from the soil through evaporation and moisture loss from plant life, officials said, and there's an easy way to find out for yourself what and how long you need to water your lawn.

The ET index they're offering, stemmed from their working with the Office of the State Climatologist at Rutgers University, is calculated utilizing air temperature, relative humidity, solar radiation and wind speed.

"Our primary responsibility is to collect environmental climate data, observe climate variables from official government and private observation stations and deliver the best information for efficient use of water lawns within the specific SUEZ delivery areas," Dave Robinson, state climatologist at Rutgers said.

"SUEZ is pleased to offer this ET program as a courtesy to residents during the summer when outdoor watering can account for a 50-percent increase in water usage," Jim Mastrokalos, Director of Operations for SUEZ said. "Lawns are often over-watered, resulting in unnecessarily higher water bills for our customers and the wasting of precious, treated water."
