Well 14
Project Type:
Water
Project Status:
Design/Engineering
Date Received:
Wednesday, November 20, 2024
The City will be expanding our well field and adding another Well. The Well 14 project includes the construction of a groundwater monitoring well (2-inch) with a drill borehole of 6-inches; municipal water supply well with a drill borehole of 20-inches 155 foot deep, with 100 feet of 16-inch permanent casing and 55 feet of 16-inch stainless steel well screen. The project includes well capacity testing, video survey of completed well, and a sanitary seal on top of the well casing upon completion of the work.
Status Updates

Utility division crews unloaded the new well enclosure for Well 14. We ordered the well closure 8 months ago and while Well 14 is not complete, at least the enclosure is here and ready to be installed when Phase 2 of the project is complete in FY2026.
Crews unloaded the enclosure at the airport, since the truck driver was not skilled in operating the truck and trailer to get into the tight quarters of the Water Treatment Plant.

Our consultants from GSI Water Solutions received the sieve analysis from Roscoe Moss Company. Our consultant team designed a screen and filter pack for the new well and provided the design specifications to our well driller on Friday, March 7th. Once ordered, the screen and filter pack will take 2 to 3 weeks to complete.

It was a rough go on Sunday, February 23rd, when the drilling contractor started drilling the new well. The drilling operator was only able to go to a depth of 15 feet location due to the winds and sideways rain. The welder, had to weld the casing together, as the well was being constructed. Welding in the wind and rain created a hazard, so the drilling operation had to stop for the day.
With the winds and rain subsiding, our contractor was able to complete the well to a depth of 155 feet below ground surface. Interesting results regarding the geology of the area. We started out with tightly compacted sand, which slowed the drilling process. Once out of the tightly compacted sand, we were in the typical sands that we encounter during well construction activity. The well driller hit the silt layer at 149 feet below the ground surface. We were actually anticipating the silt layer would be encountered at 150 feet, so having the actual geology end up matching the anticipated geology this closely was very satisfying.
The soils samples from the drilling operation were sent to GSI Water Solutions Portland office, and are being readied for shipping to Roscoe Moss Company for sieving (Roscoe Moss is also the screen manufacturer). GSI Water Solutions will develop a screen design after receiving the sieve results from Roscoe Moss Company. After the screen is designed and manufactured, the well driller will install the screen and begin the process of developing the groundwater well.

Our contractor completed the development of the service road to the Well 14 location as well as the pad for the drill rig to set up on. The well driller has started to bring in materials for the drilling of the well. This included the well casing materials. The revised schedule for the drilling contractor to start drilling the new well is Saturday, February 22nd and have the drilling completed by Thursday, February 27th.
February 14th, 2025
Our contractor has been on site developing the service road to the Well 14 location. The contractor is grading; compacting the sand; placing geotextile road fabric; placing 3” minus crushed rock and compacting it in place. This will allow them to access the well site with their drilling rig. Included in this work is the grading and leveling of the pad in order for the drill rig to be level and plumb.
February 7th, 2025
We received the final order from the Oregon Water Resources Department (ORWD) approving our request for an additional point of appropriation for the new well. It was back in January 2023 that we filed an application to add the new well as an additional point of appropriation under our existing water right permit G-16885. With the new point of appropriation, T-14146, our water right permit has been given a new number G-18896. A lot of time and effort went into gaining OWRD approval to be able to withdraw water from the new well. This included operating Wells 8-13 in August 2023 in order to be able to complete a partial perfection of 2.4 cubic feet per second (CFS) withdraw from the aquifer for Wells 8-13 (we have different groundwater rights that cover Wells 1-7). Navigating the OWRD process to achieve this milestone has been quicker than most with the process only taking two years.
Speaking of our Water Rights, the City holds three groundwater rights for use up to a total of 5.89 CFS (3.8 million gallons per day) and one surface water right (on Munsel Creek – appropriation point behind the old PW shop on Spruce) for 0.8 CFS (0.5 MGD).
January 24th, 2025
Public Works staff met with Holt Services, Inc. (our well drilling contractor) and GSI Water Services for the pre-construction meeting for the development (drilling) of the new water production well. The pre-construction meeting establishes communication protocols; work days and hours; access to the site and expectations for maintaining the security of the wellfield; formation sampling (sampling of the drill cuttings); and water sampling at the conclusion of the constant rate water pumping test.
December 20th, 2024
We received bids from the two well contractors that were prequalified for our project. Staff and our engineer are reviewing the bid proposals.
December 6th, 2024
We held the mandatory pre-bid meeting for the project on December 2nd. We had four well constructor companies (well drillers) attend the pre-bid meeting. The well constructor’s have until December 9th to submit their pre-qualification materials. The well constructors must be an established business (minimum three years) doing like projects (drilling in a dunal aquifer) and experience and equipment necessary to complete the job. As we have discovered over the years, not all well constructors have the equipment or experience to develop a well in dunes along the coast.

The City is now excepting Bids on the Well 14 project. More information on biding for the project is located Well 14 Bid
