HOUSTON -- A boil water notice was issued for parts of Fort Bend County on Saturday, KPRC Local 2 reported.

With the heat flaring and no rain in the forecast, the demand for water is rising like the mercury in a thermometer. The demand in Fort Bend County District No. 34 rose so fast that the water pressure dropped.

That left residents like Jason Den and his family high and dry because of a boil water notice.

"It was low pressure, I saw a little discoloration of the water, actually it was brown. I told them not to shower," Den said.

County officials said the water wells that serve the district just could not keep up with the use. They said the water pressure dropped below 20psi.

As a result, the boil water notice is in effect for the district that serves the Seven Meadows and Hickory Creek subdivisions.

To ensure that all harmful bacteria and other microbes are destroyed, water for drinking, cooking and ice making should be brought to a vigorous, rolling boil and then boiled for two minutes.

Soon after the notice, people snapped up bottled water at local stores.

Monique Dippel said she was caught off guard.

"We didn't have any water pressure and this morning we saw the signs," Dippel said. "We weren't sure really why that was."

The county said the notice is just a precaution as they run tests to make sure bacteria did not get into the water. It will remain in effect until further notice.

In Pearland, residents like John Kerr were dealing with other symptoms of drought-like conditions. In his neighborhood, people were desperate to do something about their parched lawns.

However, extreme conditions have pressed the city of Pearland to ask residents to conserve and avoid watering the grass in the hottest part of the day.

Kerr cut off his sprinklers and decided to wait until the evening to water his lawn.

"It probably is for the best. I can understand why watering this time of day could be a little harsher on the environment and we are trying to conserve," Kerr said.

It's not just Pearland dealing with the problem.

Those who live in The Woodlands and residents in Conroe are being asked to avoid filling pools, filling ornamental fountains and washing vehicles.

Anyone with questions about the boil water notice should contact the Operations Company for your district at 713- 405-1750 or 877-405-1750.
