Odd/Even Lawn Watering

To help preserve Long Island’s only source of drinking water—our underground aquifer—SCWA has adopted an odd/even lawn watering schedule. This easy-to-follow plan helps reduce peak water demand, especially during hot summer mornings when usage is highest.

How it works:

• Homes with odd-numbered addresses (1, 3, 5, 7, and 9) water on odd-numbered calendar days

• Homes with even-numbered addresses (0, 2, 4, 6, 8) water on even-numbered calendar days

• No watering between 10 a.m. and 4 p.m. — most water is lost to evaporation during these hours

Why it matters:

• Reduces stress on water infrastructure
• Ensures even pressure at your tap throughout the day
• Helps avoid costly expansions like new wells and pump stations
• Supports the long-term health of our aquifer

It’s good for your lawn, too:

• Daily watering can lead to shallow roots, making your lawn more vulnerable to heat and drought
• Watering every other day encourages deeper root growth and healthier, more resilient grass
• Following the schedule means less waste, stronger lawns, and a greener yard all season long

Set your sprinkler system to follow the odd/even lawn watering schedule today!
