During 2013, a total of 1,298,965,000 gallons of water was pumped from the District’s Wells. Of that total, 53,822,000 gallons were supplied under contract to the Glenwood Water District and 8,390,000 gallons were supplied under contract to the Albertson Water District. Metered water sales to District consumers including Glenwood residents and a portion of Albertson residents account for is 1,186,410,000 gallons. This leaves an unaccounted for total of 112,555,000 gallons. This is the amount of water used during the year for flushing hydrants, firefighting, main breaks and service line leaks. It represents 8.67% of the total water produced.

Water Source Restrictions
Our water service to customers in 2013 continued without interruption or restriction due to contamination of water quality.

Water Conservation Measures
The Roslyn Water District has implemented a water conservation program, portions of which are contained in the Ordinances of the District including regulations of lawn irrigation systems, which require all systems to have time clock controllers and a rain or soil moisture sensor. Sprinkling of lawns and gardens can only be performed between the hours of 4:00 p.m. and 10:00 a.m. for a maximum of 2-hour duration on alternate days; on odd days for odd numbered premises and even days for even numbered premises, and even days for premises with no numbers. Consumers are required by law to comply with these regulations. Consumers can reduce water by promptly repairing leaks as soon as they are disclosed. A leak of one drop per second wastes 2,400 gallons per year. Consumers can also reduce water use by installing aerators on faucets, displacement devices in toilet tanks and automatic shut-off nozzles on garden hoses. During remodeling, if old plumbing fixtures are replaced, the law requires that new fixtures must be of the approved water saving type. Each customer should reduce overall water use by at least ten (10) percent.

Facility Modifications
We constantly work at improving and upgrading our facilities. During the past year, we have completed the following projects:

  • Replaced Well Pump and Installed Liner Screen at Well No. 3
  • Installed Chemical Treatment Vault and Venturi Meter at Well No. 4
  • Upgraded District's computers
  • Installed New Tablet Chlorinators
  • Installed New VFD Drives on Booster Pumps "A" and "C" at Plant No. 4
  • Installed New VFD Drive on Booster Pump "B" at Birch Drive
  • Installed New 100 HP motor on booster Pump "D" at Birch Drive
  • Supervisory Control and Data Acquisition System (SCADA) - Completed

Annual Average Charge for Water
Our water rate structure is designed to promote conservation; the more you use, the more you pay. The average consumer pays a minimum quarterly charge of $10.56 for 12,000 gallons. Our water rate is $0.88 per 1,000 gallons for the first 21,000 gallons consumed; $1.10 per 1,000 gallons for the next 21,000 gallons; $1.65 for the next 66,000 gallons and $2.36 per 1,000 gallons for quarterly use over 108,000 gallons. The average annual cost for metered water for a residential user in 2013 was $221.39 or 61 cents per day. The average tax levy per residence is $231.20

Educational Information
Drinking water, including bottled water, may reasonably be expected to contain at least small amounts of some contaminants. The presence of contaminants does not necessarily indicate that water poses a health risk. More information about contaminants and potential health effects can be obtained by calling the EPA’s Safe Drinking Water Hotline (1-800-426-4791).

Some people may be more vulnerable to disease causing microorganisms or pathogens in drinking water than the general population. Immuno-compromised persons such as persons with cancer undergoing chemotherapy, persons who have undergone organ transplants, people with HIV/AIDS or other immune system disorders, some elderly and infants can be particularly at risk from infections. These people should seek advice from their health care provider about their drinking water. EPA/CDC guidelines on appropriate means to lessen the risk of infection by Cryptosporidium, Giardia and other microbial pathogens are available from the Safe Drinking Water Hotline (800-426-4791).

The sources of drinking water (both tap water and bottled water) include rivers, lakes, streams, ponds, reservoirs, springs, and wells. As water travels over the surface of the land or through the ground, it dissolves naturally-occurring minerals, and, in some cases radioactive material and can pick up substances resulting from the presence of animals or from human activities. Contaminants that may be present in source water include: microbial contaminants; inorganic contaminants; pesticides and herbicides; organic chemical contaminants; and radioactive contaminants. In order to ensure that tap water is safe to drink, the State and the EPA prescribe regulations which limit the amount of certain contaminants in water provided by public water systems. The State Health Department’s and the Food and Drug Administration’s (FDA’s) regulations establish limits for contaminants in bottled water which must provide the same protection for public health.

Annual Water Quality Report Supplement
A supplement to this Water Quality Report has been prepared which contains the analytical results of water quality monitoring from the individual wells in the District. This report is available at the District office.

Thank you for allowing us to continue to provide your family with quality drinking water this year. We ask that all our consumers help us protect our water sources which are the heart of our community and our way of life. Please call our office if you have questions.
