Grant funding approved for John Day wastewater irrigation study, seven other proposals
The City of John Day has obtained a $50,000 grant to study the possibility of using wastewater for hyroponic crop production or pasture irrigation.
The award was one of eight grants totaling more than $400,000 approved for water project feasibility studies by the Oregon Water Resources Commission.
John Day currently stores treated wastewater in four ponds near the John Day River, but the system may not pass regulatory muster in the future due to potential adverse impacts on water quality.
For this reason, the city wants to examine re-using the wastewater, which amounts to 87.6 million gallons annually, in hydroponic greenhouses.
The other option would be to pipe the water to two 40-acre lagoons north of town, which would feed a 120-acre center pivot irrigation system.
The total cost of the study is expected to be $110,000, with matching funds provided by the city and another state grant program.
After the approval of the eight grants, the Oregon Water Resources Commission still has more than $600,000 available for future water project feasibility studies.
One of the proposals submitted to the commission — $93,935 to study removing sediment from the Applegate Reservoir in Southern Oregon to increase storage capacity — was rejected.
The Oregon Water Resources Department, which is overseen by the commission, recommended against funding the study because it only proposed removing sediment, which is a temporary solution.
The study would be stronger if it also looked at preventing future sediment buildup by reducing it from upstream sources, according to OWRD.
Following is a summary of the other water project feasibility grants approved by the commission:
• $30,000 to study the re-use of wastewater from Baker City for agricultural purposes.
• $60,000 to study expanding the City of Carlton’s water reservoir.
• $72,500 to study whether to rehabilitate or remove the City of Brookings dam and reservoir.
• $50,330 to study the possibility of paying landowners to forgo irrigation to increase stream flows in the Hood River Basin.
• $65,680 to study above-ground and below-ground water storage in the Upper Klamath Basin.
• $42,297 to study aquifer storage and recovery in the Milton-Freewater area.
• $40,505 to study natural water storage in a wet meadow in the John Day River Basin.
