CCWD Frequently Asked Questions

What Do I Do If I Think I Have A Leak? 

If you suspect you may have a leak, click here for a simple guide that will help you determine if you have a water leak or watch this video with step-by-step instructions on using your water meter to determine if you have a leak.

We have two policies that may help you after experiencing a leak:

If you choose to apply for a leak adjustment, please fill out the leak adjustment request form and mail it to CCWD:

Is The Water Safe To Drink? 

Absolutely. The treated water delivered to CCWD customers meets all state and federal water quality regulations and is continually tested to ensure its safety. We’re proud of the high-quality drinking water we provide to our community, and you can see all of our water quality test results here.

Is The Water Fluoridated? 

No, CCWD does not add any fluorides to the water.

Is The Water Hard? 

CCWD water is not considered hard when compared to most of the State. For example, in the areas served by the Los Angeles-based Metropolitan Water District (MWD) in Southern California, hardness is regularly 11.7 grains / gallon is common. Delta water falls into the 5.3 – 5.8 range. CCWD’s treated water averages are listed below. Water hardness makes cleaning tasks more difficult and forms scale in home water heaters and industrial boilers. On the other hand, soft water tends to be corrosive.

All numbers shown are grains / gallon:

  • Copper Cove 1.88
  • Ebbetts Pass 1.29
  • Jenny Lind 4.35
  • Sheep Ranch 1.53
  • West Point 1.88

Typically water sodium levels in CCWD’s water is below 10 mg/l.

What Are Disinfection By-products And What Is CCWD Doing About Them? 

Disinfection by-products (DBPs) are potential cancer-causing substances that are formed when chlorine is used as a disinfectant during the water treatment process. All surface water supplies, including CCWD’s, contain natural organic substances which chlorine converts to DIBPs. There are two classes of DIBPs the EPA is concerned about – THMs and HAAs. Currently only the THMs are regulated at 100 parts per billion. CCWD routinely measures these contaminants and at all plants the THMs are below that level. To learn more about DBPs go here:

Are Bacteria Present In The Water? 

All raw water sources, including CCWD’s three river sources, Stanislaus, Calaveras and Mokelumne, contain bacteria – most of which are not disease-causing. The disinfection process at each of our six (6) water treatment plants destroys any potentially harmful bacteria. CCWD conducts weekly tests at various points in our distribution system to make sure no disease-causing bacteria are present in the water supply. Test results have always been well within state and federal requirements.

Is There Lead In The Water? 

The Environmental Protection Agency (EPA) requires water utilities throughout the country to advise consumers of the possibility of lead contamination from home plumbing systems. Although the quality of water delivered by CCWD is much better than that required by federal and state drinking water standards, under special circumstances, lead can get into your tap water as a result of the corrosion of old household plumbing materials containing lead. In August 1988, the EPA proposed the new maximum contaminant level for lead to be 0.005 mg/l – a change from 0.050 mg/l established in 1975.

CCWD is cooperating fully with the EPA to conduct sampling and to educate the public on this subject. Many CCWD customers have collected samples for lead and copper testing through the years. CCWD adds corrosion prevention chemicals at each of its six (6) treatment plants to prevent these elements from entering your drinking water.
