Before we get used to rain and forget about the high water bills from this record breaking extended dry summer, it is important to understand the non-weather factors impacting irrigation water costs.
Did you know that the average price for water in the Portland Metro area has doubled in the past 6 years? As you can see from the chart above, all rates have risen, some more than others, and the rates vary widely from city to city. Good news for those of you in Gresham as your rates have risen the least and your water is the cheapest. Bad news for those of you in Wilsonville and Tigard as your rates have risen the most and are the most expensive.
The reason for the differing rates is not completely understood but "it is what it is". The point we want to make is to prepare for annual increases greater than the overall inflation as that has been the pattern for the past 7 years and will likely continue.
Another point to make is that as water rates rise, conservation projects make more and more financial sense. Whether or not you want to "save the world" by conserving water, you all will agree that high ROI conservation projects are a "no brainer".
WEATHER BASED IRRIGATION HAS GREAT ROI
