Reducing Thermal Loads into Waterways
The City of Enterprise would like to educate the public to the benefits of shading the streams throughout our community. Water quality in the Lower Grande Ronde Sub-basins currently do not meet some water quality standards. The City of Enterprise is located within the Wallowa River Sub-basin, which is one of the Lower Grande Ronde River Sub-basins. One of the concerns throughout the area is high temperatures in our streams. When water quality standards are not met, the Federal Clean Water Act requires a Total Maximum Daily Load to be established, which determines how much pollution can be added to the river without exceeding water quality standards.

Protection from Thermal Expansion
The City of Enterprise would like to inform our customers on how to protect your water heater from thermal expansion. The City is required to have a cross-connection program in place to prevent the contamination of our drinking water. On all our new service connections and any that we have been replacing in the last ten years we have been installing meter setters that have check valves installed in them. These check valves prevent the back flow from the household plumbing system from going back into the public supply.

Enterprise Wastewater Treatment Facility
Facts that you need to know:
The City of Enterprise’s wastewater treatment facility was originally constructed in 1955. The 1955 treatment facility project consisted of construction of a preliminary treatment system including headwork’s, one 35 foot diameter primary clarifier, a 54 foot diameter rock-media trickling filter, one 35 foot diameter secondary clarifier, sludge pumping facilities, a control building, an 18.5 foot diameter anaerobic digester with external heat exchanger and mixing pump, sludge drying beds, a gas chlorinator system, and an outfall to the Wallowa River.
In 1986, the City received a Community Development Block Grant for $424,000 to complete limited improvements to the wastewater collection and treatment facilities. The limited improvements focused primarily on isolated repairs of the collection system to target reduction of the severe infiltration/inflow problem the City experiences in their collection system, a minor amount of work at the WWTF, and construction of an effluent polishing and dechlorination lagoon.
This 1955 WWTF was constructed to handle 750,000 gallons of wastewater per day. This treatment facility served the City well for 52 years, regulations over that 52 year period got more stringent over the years and the ageing facility was having problems staying in compliance with the DEQ’s regulations. At times flows would run into the 1,000,000 gallons/day at certain times of year because of the infiltration problems the City had in certain parts of their collection system. This facility was having problems meeting the DEQ’s permit limits for flows, biochemical oxygen demand, suspended solids and E-coli that were being discharged into the Wallowa River.
