Estimated Cost: $8.2 million
Constructing a 3 million gallon, concrete wire-wrapped cylindrical tank at 147th Ave and Faris St. Provides much needed storage for Sunrise’s largest service level.
Construction: April 2018 – December 2020
The construction work at Reservoir 11 has been largely completed with only a few tasks left to do. Work on the landscaping will begin the week after Labor Day. The end of this monumental project is in sight.
Spring weather has arrived, and with it, the final push to complete the reservoir project. Construction activities will be begin again on or after May 11. The primary tasks remaining are connection to a storm water line in SE Verlie Street, backfilling around the reservoir, and final grading in preparation for landscaping in the fall.
The COVID-19 pandemic stay-at-home order means that many of our neighbors are trying to work from home and deal with kids at home as well. Out of respect for the added stress our neighbors are under, Sunrise has requested that construction crews not to begin work until 8:00 am each morning, with an allowance that they can be onsite and preparing for work at 7:30 am.
Wet weather has moved in and construction activities at the reservoir site will be suspended until drier weather arrives in the spring. We were pushing hard to try and complete back filling before the wet season arrived, but nearly record rainfall in September made that impossible. There are two primary reasons for this. First, it would be impossible to keep the surrounding streets clean and mud free with trucks coming and going with loads of back fill material. Second, when back fill material becomes too wet, it isn’t possible to pack it to meet engineering standards. Erosion control measures have been put in place to minimize runoff as much as possible.
There will be very little activity at the site through the winter. Staff tending to erosion control issues and a small project connecting to the storm pipe in the street are all that is planned. While Sunrise Staff will be checking on the site regularly, we would appreciate it if our neighbors could keep an eye on the site and report any issues or suspicious activity to Dan Fraijo at 503-572-6018.

The reservoir has passed leak tests and been placed in operation. Even though the site still needs extensive work to return it to normal, the reservoir has water in it and is being used as part of the water system. Trucks will begin hauling material to the site to backfill around the reservoir soon, possibly starting on August 12. Around 30,000 yards of material will be needed to bury the reservoir and restore the site to conditions where landscaping can be installed.

Reservoir 11 is getting water!!!! As of today, the reservoir is beginning the filling process. It will take some time to bring the reservoir up to capacity. As it fills, the structure will be inspected for leaks. Once the integrity of the structure is assured, it will be painted and backfilling can begin. The painters are starting on the existing reservoir today. The white and blue color scheme is being replaced with a light tan that was selected by the community.

Put a lid on it! The contractor will pour half of the roof of the reservoir on Friday. On Friday, March 29th crews will start setting up at 7:00 AM, with the first concrete truck scheduled to arrive at 7:30 AM. It is anticipated that 25 trucks, or about 2500 cubic yards of concrete, will be needed for the pour. We expect the pour to be completed during the normal work day, barring any unforeseen complications in the process.

On March 21st folks living near the new Reservoir 11 were invited to get a look inside their new neighbor. Take a look at the scale of the roof support columns. Construction is moving along on schedule and the first half of the roof will be poured soon.
March 6 –
The majority of the wall sections have been poured. The last section will remain open until interior work is completed. The bulk of work during March will be forming and pouring the roof. Next week, the existing tank will be pressure washed to prep it for coating. The coatings used on reservoirs have unique properties and some limitations on color choices. The coating contractor will be painting some sample swatches in the coming week so that we can review the options.
