This article provides an in-depth, practical guide for when and how to change irrigation practices across Oregon’s […]
Overview and purpose Backflow preventers protect potable water supplies from contamination or pollution caused by reverse flow. In irrigation systems the risk is elevated because of fertilizers, pesticides, soil amendments, standing water, and variable pressure conditions. Oregon jurisdictions and water purveyors require appropriate backflow prevention based on the degree of hazard, system layout, and local […]
Retrofitting an older sprinkler system is one of the highest-impact, cost-effective ways to reduce residential and commercial outdoor water use in Oregon. Many systems installed 10, 15, or 25 years ago were designed for uniform coverage, not water efficiency. This article lays out practical, step-by-step guidance for auditing, upgrading, and maintaining older irrigation systems so […]
Oregon’s climate range — from the wet, mild Willamette Valley and coast to the dry, continental eastern valleys and high desert — means a one-size-fits-all approach to mulch and irrigation is inefficient. Thoughtful combinations of mulch type, depth, and irrigation technology reduce water use, protect soil biology, suppress weeds, and keep plants healthy through wet […]
Why this matters in Oregon Clay soils are common across many parts of Oregon, especially in lowland valleys and areas with ancient floodplain deposits. Clay holds water tightly and has low natural infiltration, so when you apply irrigation water faster than the soil can absorb it, runoff happens. Runoff carries nutrients, sediments, and pesticides into […]
