Water restrictions lifted in Decatur, IL

Thursday, December 29th, 2011

After recent precipitation raised the water levels of Lake Decatur in Illinois, Decatur city officials ended mandatory water use restrictions for residents on December 28.

Assistant city manager Billy Tyus said the water conservation efforts were originally implemented earlier in the year due to the lack of rainfall. Tyus said the second half of 2011 hadas the worst drought the city has seen in 23 years, the Herald-Review reported.

The source reported the water restrictions started in the beginning of October, and allowed residents to water their lawns and wash their cars in their driveways on certain days of the week. Restaurants were told to only bring water to the table if a customer asked for it, and bulk water prices were increased throughout Decatur. This is the third time in the last seven years that Decatur residents had to practice water conservation efforts due to a threat of a water shortage.

A water conservation measure in the Santa Clara Valley was also recently lifted by city officials. Although the mandatory 10 percent water conservation program ended, water district workers implemented a 10 percent voluntary conservation effort in its place. The water conservation plan was changed to voluntary after above average rainfall, healthy groundwater storage levels and a strong conservation response from residents helped bring the city back to a stronger level of water, the Gilroy Dispatch reported.

Water leak blamed on human error

Thursday, December 29th, 2011

A major pipeline burst last month in southern San Francisco, sending more than a million gallons of water through the local neighborhood and causing damage to homes and vehicles. The cause of the leak is blamed on human error.

According to the San Francisco Chronicle, a San Francisco Public Utilities Commission engineer failed to include a crucial restraint that holds pipeline connections in place in his design of the water system. The flaw led to a 60-foot geyser of water in late November, and the flowing water damaged sidewalks, landscaping, dozens of homes and many cars in the area.

"There's no excuse," Stevie Ritchie, the utility's assistant general manger for water, told the source. "It was human error that caused it. In this case, it was not in the plans, and therefore, the contractor didn't install it."

Bay City News reported the human error led to a bad coupling holding together pipes of different sizes. The joint coupling failed to contain a restraint part, which would have prevented the joint from bursting. Two pieces came apart that should have been joined together, thus allowing for the 60-inch water main to burst.

Since the leak was discovered, 35 similar joints that are being installed as part of the utility's $4.6 billion Water System Improvement Program are being analyzed by engineers. All couplings are now being checked for a restraint part in their designs, the source reported.

Nuclear plant closes due to water leak

Wednesday, December 28th, 2011

A nuclear plant in Plymouth, Massachusetts, recently shut down when workers suspected a safety relief valve was leaking water.

Massachusetts news source WATD reported the leaking valve provides overpressure protection for the plant's reactor coolant system. When the valve opens, it discharges reactor steam into the suppression pool to relieve pressure.

Plant owner Rob Williams told the Boston Globe that the leaking valve is one of four in the plant designed to prevent pressure buildup in the facility. Workers were able to detect the leak with temperature sensors, and the repairs are not expected to take very long.

An NRC inspector told the source that shutting down the plant for maintenance and repairs is relatively common, and are not signs of safety concerns. For the shutdowns to cause a problem, there would have to be more than six shutdowns over 7,000 hours of plant operation, and this plant had zero shutdowns in 2011 as of the end of the third quarter. In November, however, the station was shut down due to another valve problem located elsewhere in the plant.

San Clemente will reduce water use in January

Wednesday, December 28th, 2011

The city of San Clemente, California, is asking its residents, businesses and homeowner's associations to conserve water while a regional water treatment facility is shut down for regular maintenance.

The Metropolitan Water District's Diemer Filtration Plant will receive a series of operational upgrades and improvements on its new ozone treatment system, the San Clemente Times reported. The filtration plant currently accounts for 85 percent of city water customers' services. These customers, however, will receive their water from the Upper Chiquita Reservoir and underground water supplies during the maintenance, the source reported.

Similar conservation efforts are being implemented in Jamaica. The Office of Disaster Preparedness and Emergency Management recently reminded the Jamaican public to conserve their water usage in the upcoming months when the traditional dry season sets in, the Jamaica Observer reported. The ODPEM recommends residents pay attention to the amount of water they use and try to reduce that amount or reuse water whenever possible during the first four months of 2012.

Gas leaks lead to traffic disruptions

Tuesday, December 27th, 2011

A gas leak was recently discovered in the Lake Park subdivision of Albany, Georgia, when a local resident smelled a strong odor of gas and called 911 for assistance.

Georgia news source WALB reported firefighters pinpointed the source of the leak to an underground line in an alley next to a residential home. The streets were closed and fire crews went door to door to evacuate nearby homes, readying their fire hoses as precaution in the event of a fire.

"Anytime you have a flammable gas that's escaping, there's always an ignition, you know an ignition source there's always that chance so our main priority was to limit access to it and then we stood by in case there was some type of ignition we were there to extinguish it," AFD Battalion chief Kelly Harcrow told the source.

Traffic was recently stopped in Cornelius, North Carolina, as well due to a gas leak. Lake Norman news source WBTV reported a contractor was digging in the ground and cut a gas line. Local residents started to smell the gas in the air and called the police. Crews had to close down a busy street in the area in order to properly fix the leak. About 70 customers were without gas as repairs were made.
