How about draining my pool. Any special steps for that?
The city recommends draining swimming pools into a sanitary sewer. 

How come the taste of my water changes from time to time?
The minerals in a water supply affect the “taste” of the water, just like different brands of bottled water will taste different. Livermore Municipal Water receives all of its water supply from the Zone 7 Water Agency, the Valley's water wholesaler. Zone 7 treats water from the State Water Project in the Sacramento-San Joaquin Delta, and from groundwater wells in Pleasanton. As part of managing these potable (safe to drink) water sources, Zone 7 will vary the mix of treated surface water and disinfected well water delivered to the retail water agencies in the Valley. Over the course of a year, Livermore Municipal Water receives mostly treated State Water Project water. On occasion, it will receive more groundwater. The variation in the mix of surface water and groundwater delivered to Livermore may result in changes in the taste of the water.

Why does my water smell?
To determine the cause of the smell, let your water run for 30 seconds before rinsing and filling a glass. Characterize the smell.

  • No smell: The smell is probably coming from bacteria in the P-trap under the drain. Other smells could be from home water treatment systems — check the system, e.g. filters.
  • Chlorine/Chemical: Oftentimes, the smell detected is the result of chlorine used to disinfect the water supply. If the smell is particularly bothersome, let the water stand in an open container until the chlorine dissipates.
  • Foul smell: Foul odors often come from drains or garbage disposals. The rotting organic matter or bacteria in the drain/disposal are stirred up when the water is turned on. To get rid of the odor, fill the sink with hot water, add an ounce of household bleach, and allow the water to drain slowly.
