Is my water safe from lead and copper?


Is my water safe from lead and copper?


The short answer: YES


Federal regulations require Paradise Irrigation District to sample for lead and copper in your drinking water and then the state reviews those samples. Based on the sampling results, there is no reason for concern. The samples show no lead and only minimal results for copper—and those levels are well below the action level of the Health Department.

Water Quality

Source of Drinking Water Supply

The Paradise Irrigation District derives its water from the surface runoff flowing into Magalia and Paradise Reservoirs. An emergency ground water source of 450 gallons per minute is available from a well ("D" tank) located at Lovely Lane.

Water Permit

The Districts' water system is operated under a Domestic Permit which was first issued by the California State Department of Health Services, Public Water Supply Branch, in July of 1964. This permit is reviewed annually.

Drinking Water Standards

California Drinking Water Standards are established by the State of California under the California Health & Safety code and California Administrative code, Title 22. They are administrated and enforced by the State Department of Health Services. The District's water treatment process consists of coagulation, clarification, filtration and disinfection. The treatment process is designed to remove suspended, chemical, and biological matter from the raw water sources. Our present filtration capacity is 22.8 Million Gallons per Day (MGD) which is sufficient for 100% of the maximum daily demand. Chlorine is used as the disinfectant to destroy potentially harmful bacteria, viruses, and other organisms. The amount of chlorine required varies, from 0.5 milligram per liter to 1.50 milligram per liter.

Water Quality Testing and Reporting

icon Water Quality Report 2011-2012


Paradise Irrigation District must meet strict State and Federal Standards for drinking water. Our distribution system operator routinely collects water samples each week for microbiological contaminants and sends them to a state certified laboratory for analysis. This test is conducted to see if the water contains a specific bacteria known as coliform bacteria. The absence of these bacteria is an indicator that other disease causing organisms are not present in the water. The test results are sent to the Department of Health Services in Redding, CA as well as to our agency, by the lab.

In addition to the constituents listed in this report, we have conducted monitoring for additional organic chemicals for which the California Dept. of Health Services and the United States Environmental Protection Agency have not yet set a standard. All samples and all results were below detection levels unless otherwise noted. District staff collects all samples and the tests are performed by State approved labs. Results of the tests are monitored by the District staff and are forwarded to the State Health Department.



Who Needs a Backflow Device?

Installation of an approved backflow prevention assembly is required at the service connection to any premise where there is an auxiliary supply or system - even if there is no connection or cross-connection. For example, anyone with an alternate source of water such as a well, spring, stream, etc., or anyone with an irrigation system, Residential or Commercial Fire Sprinkler System, or two or more meters serving one parcel must have a backflow prevention device. Commercial and professional buildings with lab equipment, boilers,  chemicals etc., are further examples of premises that require a backflow prevention device.

The State of California Administrative Code, Title 17 and chapter 6.14 of the Policies & Procedures of the Paradise Irrigation District, require the owner of any premises on which protective devices are installed to have certified annual inspections made of such devices for their water tightness and reliability. The device shall be serviced, overhauled, or replaced whenever found to be defective. Certified records of such inspections and/or repairs are required to be submitted to the District. You may engage any Backflow Prevention Tester who is USC and AWWA certified to perform the test, or you may have one of our certified employees perform the test. However, PID will not be responsible for any repairs, re-testing, or any plumbing problems that may occur on your premises due to the testing procedures.

Cross-Connection Control Terms


A back-siphonage condition can occur whenever there is a lowered pressure between the potable and non-potable supply piping. Such conditions typically occur during periods of high demand in the public water main, lowering the supply pressure. For instance during the demands imposed by fire fighting operations, or in the event of a water main break, which suddenly and significantly lowers the city water pressure below that of the non-potable system. This results in a partial vacuum being drawn on the non-potable system, and siphons the pollutants or contaminants into the potable water system through an unprotected cross connection, such as a hose bib or hydronic system make-up connection. Back-siphonage may also occur when a high velocity stream of water passes by a small pipe outlet, such as a residential service tap, due to the "venturi" effect.
