District crews are busy replacing deteriorating steel mainline from the Columbia River Pump Station to the PVC distribution lines.  Those lines have been replaced over the last 15 years.  There are a few sections of 12-inch distribution lines to be replaced also.

 

Main Canal
Crews have already begun replacing deteriorating and failing panels.  30 concrete panels have been replaced so far in the 8th Street West area, with about 8-9 more to be replaced there to complete that project.  There will be MANY more panels to replace along the length of the canal throughout the winter, this is just the first project.  We will also have someone in the excavator all winter cleaning silt and debris out of the bottom of the canal – an endless job!

 

If you have any maintenance concerns, please call the office at 541-922-3814 right away so they can be evaluated.  If work does need to be done, it’s easier to get the news now rather than just before water starts when it is harder to schedule.  Thanks!

WEID Received Hermiston Water August 16th

WWTP-018-2 WEST EXTENSION IRRIGATION DISTRICT/CITY OF HERMISTON

CLASS A WATER REUSE PROJECT

 

West Extension began receiving the City of Hermiston’s class A recycled water from their new waste water treatment plant on August 16th, 2016.  The Governor’s  Water Resources Commission had a joint meeting with the Environmental Quality Commission in Hermiston August 18-19, and were on hand to celebrate the occasion in addition to touring other ag-related issues in town.

Recycled Water Info June 2016

Project Overview

The City of Hermiston invested years seeking a long-term solution to discharge its Class A recycled water during the summer irrigation season. New discharge regulations designed to protect salmon in the Umatilla River left the City unable to discharge to the river during this period. During the same timeframe, West Extension Irrigation District (WEID) observed flows decreasing in the Umatilla River, which limited their ability to withdraw critical irrigation supplies. Discussions between the City and the District began in 2007 to determine if a mutually beneficial arrangement could be created. WEID first had to be assured that the recycled water was compatible for their use, not create a burden to its irrigators and would provide clear benefits to its farmers and landowners. To address these concerns the City and the District worked closely with WEID’s partner, the Bureau of Reclamation. They interfaced with several governmental/public agencies including the Oregon Farm Bureau, Oregon Tilth, the Confederated Tribes of the Umatilla Indian Reservation, Oregon Fish and Wildlife, the Department of Environmental Quality (DEQ), and National Marine Fisheries to perform environmental reviews and develop a regulatory framework for the process.

After all processes, reviews and permits were complete, WEID began receiving water from the Hermiston Recycle Water Treatment plant in the summer of 2016.

Water Quality

The recycled water meets the most rigorous quality standards in the industry, termed “Class A Recycled Water.” To continuously meet Class A standards the City invested $27 million in its Membrane Bioreactor Treatment System that produces water that is virtually indistinguishable from drinking water. For example, drinking water for human consumption must have turbidity (a measure of cloudiness of the water) of less than 0.3 turbidity units over 95% of the time. The new Recycled Water Plant will routinely produce a turbidity of less than 0.1 turbidity units.

Regulations

The project will reliably meet NPDES permit levels for the next 20+ years; increase treatment capacity from roughly 1.7 MGD to 3.0 MGD to match projected population growth in the service area by 2026; address environmental concerns impacting the Umatilla River and threatened salmonid species; and discharge the highest quality Class A Recycled Water to the Umatilla River.

Monitoring

The City monitors the turbidity continuously at the treatment plant. A system is in place wherein automatic alarms and shut-downs occur when the turbidity exceeds 0.5 NTU. The total coliforms are monitored daily.

Invitation

Customers of WEID are invited to tour the Hermiston Recycle Water Plant facilities. Please contact WEID Manager, Bev Bridgewater, to arrange for a tour.

Irrigation Mainline Repair UPDATE

3:20 pm — the repair is complete and the system is back up and running.  Thanks to our field crew who worked hard today to get the repair done today!

Due to a leak on our mainline near our 7th Street Pump Station in Irrigon, we have turned that booster station off to work on the leak.  The system will be down for the day.

Watch here for updates on when the system will be turned back on.

If you have any questions, please call the office at 541-922-3814.

Irrigon Mainline Repair

A leak was found this week on the 24-inch mainline in Irrigon between Washington and Hwy 730.  This line serves the Huke Pump Station, Country Garden Estates, the Hellberg properties, McNamee properties, the 4th St. pump station and several other landowners.  It will be down for repair the morning of Monday, June 13 for 24-36 hours (estimated hours).   Irrigators should plan to water off-schedule during the weekend and the days following the repair so they don’t get behind in their watering.

Wind Notice

The forecast for this weekend calls for winds up to 30 mph sustained.  Special precautions need to be taken around open ditches and laterals during windy weather.

Wind can cause problems in a very short period of time here in Eastern Oregon.  Tumble weeds tumble into our canals and ditches very easily!  If it is windy, please follow your water to insure that ditches are clear and able to take water.
