The department's Dave Brent says the rented pumps are being installed in case the river depth drops below the 12 feet required for the city's largest pumps to operate.
"There's a design in a pump where it needs a certain water surface elevation over the top of it," says Brent. "If you get below that point, it can start cavitating which is basically drawing air in with the water and that can damage the pumps."
Brent says with Folsom Lake at historically-low levels the City will try to use as little American River water as possible.
But, the backup pumps will be ready to draw 24-million gallons-a-day if needed.
The Sacramento River pumping station is offline until March.
The city plans to have 13 million gallons per day of well water available once maintenance is complete on some city wells in the middle of February.
"The ground water in the area and in city itself is healthy," Brent says. "We've done, over the years, what we call conjunctive use, so in those wetter years, we try to utilize the river more and let the groundwater recharge. Now we're going to be more reliant on ground water."
Brent says well water could contribute 13 million gallons a day to the city supply. The Sacramento River station is expected to provide ten times that -the vast majority of the water needed this summer.
A movement around the U.S. encourages people to skip the shopping malls Friday and spend time in nature. Some national parks and state parks in California are waiving entry fees.
The latest U.S. Drought Monitor showed no change to drought conditions in California over the past week. But, the report does not include the storm that brought rain to valleys and snow to the Sierra Nevada this week.
Two million Sacramento-area water users conserved 27 percent in October, the same rate as September.
A California law, which was passed to respond to the drought- allows artificial turf on all residential property. But a Sacramento city councilman says the law should allow cities to restrict its use.
There is no change this week to the drought in California, despite the recent storms that have brought snow to the Sierra. Reservoir storage in California remains the second lowest on record.
