Water & Wastewater Water service/main repair: This encompasses the repair and maintenance of all the water mains and services in the City of Prineville. There are over 40 miles of water mains and over 3,500 water services within the City of Prineville. Sewer main/lateral cleaning and repair: This encompasses the cleaning, repairing, and unplugging of sewer mains and laterals. There are over 40 miles of sewer mains and over 3,000 sewer connections in the City of Prineville. If you see water coming from a sewer manhole, please call immediately and we’ll unplug the main. If you have a plugged sewer lateral and you have a clean out by the sidewalk, please stop using water and give us a call. Remember to call us first to determine if the blockage is on the City’s side or the customer’s side. Leak Detection: If you have questions regarding the amount of water consumption on your bill we can assist you in determining if you have a leak or not. If you do have a leak, we can turn the water off at the meter if necessary for the customer to make repairs. If you see water coming up from the ground, we can help determine where it is coming from and determine whose responsibility it is to make repairs. Meter repair/testing: The water system in the City of Prineville is metered at each service to provide accurate accounts of consumption for billing and tracking services. The water division periodically tests larger meters and repairs and maintains all meters for accurate readings for the customer as well as the City. If you are concerned about the accuracy of your meter, please give us a call. Water main flushing/valve exercising: The Water Division is required by the State Department of Health Services to flush the water mains and exercise the valves. This service helps remove sediment from the main and provide a better chlorine residual thus providing the customer with a safe and healthy water system. Operating the valves during flushing ensures that the valves are in good working condition in case of an emergency shutdown. Backflow program: This is also a requirement of the State Department of Health Services. The backflow program helps protect the water system from possible contamination by keeping water that is delivered to a customer from re-entering the City’s water system. Underground Service Alert: If you are planning on doing any underground work on your property, please call the toll free Underground Notification Center number at 1-800-332-2344. The Water Division will come and locate any water, sewer, or storm drain utilities that we are responsible for so that you can avoid possible damage to those utilities. That same number will also notify other utilities such as Pacific Power and Qwest of the area you intend to dig. Hydrant maintenance: The Water Division maintains and repairs all fire hydrants within the City so that in case of an emergency, everything functions as needed. |

Existing Wastewater Collection and Treatment Facilities
Collection System The City of Prineville sewage collection system includes a total of 204,597 feet of gravity sewers and 3,632 feet of pumped foremains, for a total of 39.4 miles of pipelines ranging in size from3 inches to 36 inches in diameter. There are five sewage pump stations located in the collection system. The collection system is currently providing adequate capacity in the City, but there are some bottlenecks in the system and extensions and upgrades are needed to support projected growth. Several major trunk sewers are needed to provide capacity to transport sewage from the build-out of the UGB to the WWTP. Wastewater Treatment Plant The design capacity of the current partially aerated facultative lagoon treatment plant established by construction of a plant upgrade in 2004-2005 is nominally 1.67 mgd. The current population in 2005 is 8,942 and a population of 17,793 is forecast for the year 2025. The capacity of the City's wastewater treatment plant will be reached by about 2013 if the projected population growth is attained. Currently Prineville is growing at a faster rate than the 3.5% per year projected rate. Depending on the actual growth, expansion of the treatment plant capacity may be required before 2013. The treatment plant is providing treatment meeting the requirements in the City's NPDES permit. Effluent Disposal Winter time discharge of effluent to the Crooked River is allowed when river flows were greater than 15 cfs. Currently that discharge averages about 1 mgd. Storage of the remaining effluent flows in an effluent storage lagoon at the treatment plant site for disposal by irrigation of 123 acres on a City-owned golf course and at a second effluent storage pond located on City-owned pasture land along Rimrock Drive. The effluent storage combined with winter discharge to the Crooked River and summer irrigation reuse on the Meadow Lakes Golf Course and on City-owned pasture is adequate for about 1.60 mgd of the 1.67 mgd design flow, but cannot accommodate future growth. |

History of the City of Prineville Water System Compiled by Jerry Brummer The Prineville Light and Water Company was the first supplier of water to the residents of the city and was formed in May of 1900. The water was taken from a system of 22 wells located on the valley floor and pumped by two duplex Dean pumps to a reservoir situated north of town. The reservoir had a capacity of 100,000 gallons and was cement lined to keep water from becoming contaminated. The tank's elevation was ninety feet above the valley floor giving the residents about 40 pounds of pressure for domestic use. The pressure could be doubled by pumping directly into the distribution system during a high demand period such as a fire. The purpose of the company was to furnish domestic water, fire protection, and water for the light plant boilers. The first distribution system consisted of 7,000 feet of 4 inch pipe, 4,000 feet of 2 1/2 inch pipe, and several thousand feet of service lines. For fire protection there were five patent hydrants and 20 Don muzzel hydrants located strategically around town. The water rates in the beginning were $2.50 a month for bakers; barbers were charged $1.50 for the first chair $0.25 for each additional chair; families were charged $0.50 a month and if they had a bathtub it was an additional $1.00. The first power plant was located between NE Court and NE Dunham, and NE Third and NE Fourth streets, and it had the ability of furnishing power for about 500 16-candlepower lights. This electrical service was provided at a flat rate of $0.05 per month per candlepower for lights used until 10:00 PM, and $0.06 if they burned until midnight. The saloons and hotels that stayed open all night could have the lights lit from dusk until dawn for $0.08 per candlepower. The 16-candlepower lamp is equivalent to a 20 watt lightbulb by today's standards. This power plant was discontinued in 1912 as it was consuming 5 cords of wood per day, or more than 1025 cords per year, at a cost of $9,125.00. In 1913 this power plant was bought out by Deschutes Power Company who continued to operate these services until 1930. Pacific Power and Light Company acquired the utility responsibilities from Deschutes Power Company and continued these services with the water department until 1985 when it was purchased by the City of Prineville. The City's current water supply comes from eight deep wells and one shallow well which are all located in the Ochoco and Crooked River valleys. Following is a list of the wells and their capacity:
The City of Prineville's distribution network is made up of a combination of asbestos-cement, cast/ductile iron, galvanized steel, wrapped steel, woodstave pipe, and PVC pipelines ranging from 1 inch to 18 inches in diameter. The pipeline system totals about 42 miles. In order to provide services to the Northridge area north of Ochoco Heights Tanks, a booster pump station was installed in 1998. There are three Suncroflo close-coupled pumps with 15hp, 25hp, and 50hp motors, respectively. The station was designed to deliver up to 1500gpm with three pumps in operation. A pressure regulator on the pump discharge limits the delivery pressure to 80psi. In conjunction with the construction of American Pine Tank, a booster pump station was installed in 2002 to provide water to the Northridge area. There are three Cornell close-coupled pumps with two 20hp and one 75hp motor. The station was designed to deliver up to 1530gpm at 181 feet of head with three pumps in operation. In 1999, a fire booster station was constructed to provide 4000gpm fire flow to the yard hydrant at Les Schwab warehouse site at the airport. One 75hp Cornell Model 10YB booster pump with a design capacity of 4000gpm at 60 feet of total head was installed and a space was provided for the installation of a second pump in the future. The City's water storage consists of five steel water tanks located throughout the city. Below is a table showing capacity of each tank:
The City of Prineville's water system has approximately 700 fire hydrants as of 2006. The fire hydrant caps are color coded according to NFC regulations based on pressure. Red caps are 0-500gpm, orange caps are 500-1000gpm, green caps are 1000-1500gpm, and blue caps are over 1500gpm. The city has the luxury of having only two hydrants in the system with less than 500gpm capacity. The capacity of the system will be determined by the growth rate of the City of Prineville and the UGB area of Crook County. It will be an ongoing challenge to provide safe drinking water, construction water, and water for fire protection for the residential, commercial, and industrial demands of the city. |
