SWS eARDWP Help Tips

  1. Water System Classification

    Community Water System A public water system that serves at least 15 service connections used by yearlong residents or regularly serves at least 25 yearlong residents of the area served by the system. The term ‘residence’ generally means single-family homes, but also includes dwelling units that are more or less equivalent to a residential home. This would include cabins, cottages, mobile homes, efficiency living units, apartments, etc., that are used on a long-term basis by residents. The term ‘yearlong’ infers use that exceeds 6 months of the year. Using this criterion, examples of community water systems may include second home subdivisions, cabin clusters, apartment buildings, mobile home or trailer parks, labor camps and correctional facilities.
    Transient Noncommunity Water System A public water system that regularly serves at least 25 persons daily for at least 60 days out of the year, but does not serve the same 25 persons for over 6 months per year. The days do not have to be consecutive. Examples of a transient noncommunity water system include day-use facilities, campgrounds, resorts, rest-stops, restaurants, hotels, visitor centers, churches, cabin clusters that do not have access for part of the year, and businesses with fewer than 25 employees but regularly has over 25 customers daily for over 60 days per year.
    Nontransient Noncommunity Water System A public water system that is not a community water system and that regularly serves at least 25 of the same persons over 6 months per year. Examples include businesses with over 25 employees, day care facilities, and schools,

  7. Population: all population types should be reported regardless of the public water system classification as shown on the first page of your report.

  8. Annual Operating Period : Provide season that each population is present at the water system. If year-round, the Begin Date would be 01/01 and the End Date would be 12/31. If present only during the typical summer season, example Begin Date and End Date would be 05/01 through 09/30.

  9. Residential Population : includes all people who reside within the water system service area on a year-round basis, or have the ability to use a dwelling unit for over 6 months of the year (includes number of persons that use second homes, cabins, or other housing units).

  10. Transient Population : the number of persons served on the 60th busiest day; counting only those persons that are not residential or persons onsite for over 6 months out of the year, such as day-use visitors, campers, attendees at events, customers to a business, etc.

  11. Nontransient Population : the number of the same persons onsite for over 6 months out of the year, such as students and employees.

  12. Sources: Any source of drinking water supply such as a well, spring or surface water intake.

  13. PSCode or Primary Station Code: a unique 10-digit code assigned to each source for identification and submittal of water quality data electronically to DDW by the laboratory. The code consists of the 7-digit water system number followed by a 3-digit source code, such as: 1000222-001.

  14. INACTIVE source activity status: Inactive sources are not approved as sources of supply and must be physically disconnected or otherwise isolated so that only an intentional act by an operator can place the source into service. To change the status of an Inactive source to ‘Active’, a permit amendment application must be submitted to the local DDW Office, and approval received prior to any use of the source.

  15. STANDBY SOURCES: An emergency source that is not approved to be used for more than 15 calendar days per year or for periods that exceed 5 consecutive days. The local DDW District Office must be notified within 3 days after any use of a standby source. To change the status of a Standby Source to ‘Active’, a permit amendment application must be submitted to the local DDW District Office, and approval received prior to any non-emergency use of the source.

  16. PENDING source activity status: new sources that are not yet approved for use in the water system.

  17. Discuss Changes to Above Sources: provide information on the change in status of any source used in the water system, or the addition or destruction of any source.

  18. NSF/ANSI Standard 60 Certification of Direct Additives: Pursuant to Section 64700, Title 22 of the California Code of Regulations, (effective January 1, 1994), all chemicals or products, including chlorine, added directly to the drinking water as part of a treatment process must meet the ANSI/NSF Standard 60. If you are not sure whether a chemical you are using meets this standard, contact the manufacturer or distributor of the chemical.

  19. Chemical Use Initiated in 2014?: Indicate if you began using the chemical listed in 2014. Specify in the COMMENTS whether this is an additional chemical used in the treatment process or whether this chemical replaced one you are no longer using.

  20. Cross Connection Control: Pursuant to Title 17, California Code of Regulations, all public water systems shall protect the water supply from contamination by backflow caused by cross-connections. For premises where cross-connections are likely to occur, prevention of backflow is required through the installation of approved backflow prevention assemblies. Each backflow prevention assembly must be tested annually by a certified backflow prevention assembly tester.

  21. Flat Base Rate: Basic charge that all customers pay

  22. Variable Base Rate: Basic charge is different, depending on size of pipe, water meter, or other factors

  23. Uniform Usage Rate: The charge per 100 cubic feet of water is the same regardless of use

  24. Base Rate + Uniform Usage Rate: Single flat base rate charge plus a charge per 100 cubic feet (hcf) that is same regardless of how much is used.

  25. Variable Usage Rate: Increasing Block or Tier Rate. The charge per 100 cubic feet of water increases as water use increases.

Each backflow prevention assembly must be tested annually by a certified backflow prevention assembly tester.

  36. Backflow Assemblies On-site: this includes backflow assemblies installed within the premises of the user, which protect the internal water distribution system from cross-connections to the satisfaction of the water supplier and health agency, such that backflow protection is not required at the user’s connection to the public water system. This also includes backflow assemblies installed within a non-community water system to protect its distribution system. Examples include backflow assemblies on the water supply to boilers, RV dump stations, commercial dishwashers, and fire protection systems, etc.

  37. Air-Gap Separation: is a physical break between the water supply line and a receiving vessel, and must provide a separation of at least double the diameter of the supply pipe, measured vertically from the flood rim of the receiving vessel to the supply pipe, but in no case shall this separation be less than one inch.

  38. Inactive Backflow Prevention Assemblies: A backflow prevention assembly that is installed on a pipeline or connection that is no longer in use, as counted at the end of the calendar year 2014.

  39. Cross-Connection: is an unprotected actual or potential connection between a potable water system used to supply water for drinking purposes and any source or system containing unapproved water or a substance that is not or cannot be approved as safe, wholesome and potable. By-pass arrangements, jumper connections, removable sections, swivel or changeover devices, or other devices through which backflow could occur, shall be considered to be cross-connections.

  40. Consumer Confidence Report (CCR): Each community and nontransient noncommunity water system is required to complete a CCR on an annual basis. The CCR is to provide, as a minimum, specific information on concentration of microbiological contaminants, minerals, physical agents, inorganic chemicals, organic chemicals, and radioactivity that are present in the water supply. A template and further guidance for the preparation of the CCR can be found at the following DDW website: http://www.waterboards.ca.gov/drinking_water/certlic/drinkingwater/CCR.shtml

  42. Water Outages: Unplanned events in which the water system is depressurized and customers are out of water for any reason including water main breaks. Scheduled water outages during main replacement need not be reported. A system may be depressurized due to a well or pump failure or wildfire damage to a reservoir resulting in the reservoir being emptied.
