History of Drought and Flooding: San Francisco, San Diego

From San Francisco all the way down to San Diego and throughout the state, storms are getting weaker in terms of how much precipitation there is per day (in each storm). However, the storms are getting longer. Storms last an extra day or a few days longer. All over the state people are also having trouble with their groundwater. Every time the temperature goes up 1 degree, the potential evaporation increases by 4 percent. Scientists have analyzed the drought and estimated approximately 20 percent of the drought was caused, not by lack of rain, but by the temperature which caused the rain to evaporate. In parts of California, such as Santa Cruz, the El Niño was the largest ever observed which lead to 150–200 percent of normal precipitation. In January, the wettest month of the year, cities such as Sacramento got 1/100 of an inch of rain. Studies have predicted that a normal winter, which is four months long with rain in December, January, February and March will shrink to two months. A helpful tactic will be to install reservoirs and holding tanks in order to slow water as it goes down the hill and give it a chance to soak in. This will compensate for some of the climate change effects. Climate scientists also predict the region will get even hotter and drier. California has only about a year and a half’s supply saved behind dams and groundwater tables have dropped in a distinctive way. The number of Californians exposed to risk from a hundred-year flood could rise from the current 260,000 to 480,000 by 2100, attributed to a projected sea-level rise of 4.6 feet. Storms are expected to get more severe, with increased risk of flooding. Contact Perma Liner for all of your Cured In Place Pipelining...

San Diego’s Winter Water Usage Advisory

San Diego’s Winter Water Usage Advisory

In the City of San Diego, everyone has a San Diego water bill that includes a flat sewer rate. The rate is based on the water used during the previous winter. Instead of charging each customer a flat dollar amount, the city attaches an amount based on your usage, which covers the cost of running the sewer system. The City has implemented a winter monitoring period to calculate sewer charges on your bill from December through March. Once the monitoring period is over, a flat rate for your sewer bill is calculated and included in your monthly bill for the next year beginning in July and continuing through the following July. Essentially, if you lower your usage during these months, your sewer rate will go down and you will save money each month for one year. The winter months are when the measuring takes place because that is when the highest percentage of water used is returned to the sewer system. The City monitors your water usage during the two billing cycles when your meter is actually read, and uses the total from the cycle with the least amount of usage to calculate your sewer rate. Residential water users are urged to keep up their efforts to conserve through the winter months. That includes complying with urban water supplier directives to switch to fall watering schedules of once a week as well as a prohibition against watering during a rain event and 48 hours directly following a rain event. Water saving tips: Turn off the tap while brushing your teeth. (save up to 35 gallons a week per person) Scrape food scraps off dishes in the garbage instead of putting it down the garbage disposal. (save up to 60 gallons a week) Shorten your shower time at least every other day. (save up to 33 gallons a week per...
