With southwest Connecticut’s rainfall more than 7 inches below normal for this time of year, Aquarion said Tuesday its reservoirs are at half their capacity.

To make matters worse, demand is running more than 12 percent higher than it did for the same time last year.

“Due to the continuing drought and ongoing high water demand, Aquarion is asking customers to turn off sprinklers and irrigation systems for this season,” Charles V. Firlotte, Aquarion president and CEO said in a release. “It is important for our customers to support these voluntary conservation measures and to use our water resources wisely.”

Besides, lawns’ and gardens’ growth slow down in the fall and need less water. Many areas have already has their first frost thus ending the growing season.

More than 83 percent of Connecticut is experiencing a “moderate drought,” according to the U.S. Drought Monitor. The only parts of the state that fared slightly better, with “abnormally dry” conditions, were the southeast corner of the the state and northern Hartford County.

“Closer to the Atlantic Coast, dry weather kept moderate drought intact from northern New Jersey to southern Maine. Through October 20, year-to-date precipitation totaled 27.26 inches (79 percent of normal) in Boston, Mass., and 27.76 inches (80 percent) in Bridgeport, Conn.,” the monitor posted.

According to the National Weather Service, southwest Connecticut — specifically, Bridgeport — has had 35.47 inches of rain. That’s 7.70 inches below normal. This month, 1.48 inches of rain has fallen; the normal amount for the month is 3.09 inches.

The good news is the NWS is forecasting between 1 and 2 inches of rain Tuesday into Wednesday.

Nonetheless, Aquarion says that rain still won’t end the drought.

The company is asking customers to undertake these voluntary measures:

Repair leaks in plumbing and fixtures

Switch to water-efficient toilets, washing machines and dishwashers

Allow grass to grow longer; taller grass is healthier and requires less water

Use brooms or blowers instead of water to clean decks, driveways and sidewalks

Use a bucket and sponge to wash cars and boats instead of a running hose. Shut off ornamental water displays

Don’t run the tap continuously while washing hands, shaving or brushing teeth

Don’t stay in the shower as long as before

Hand-wash dishes in a basin, not under running water.
