Update - November 1, 2022
The sound walls for the well drilling project, came down this past week.
Orem’s tank contractor will be selected very soon and is expected to start on the site within 1-2 months.
Update - October 3, 2022
Over the weekend drilling crews installed all the casing/screen to a depth of 950 feet. They placed all but the last 25 feet of the gravel pack, they will top it off in the next few days. The contractor pumped all drilling mud from the hole and placed the chemical treatment. The chemicals need to sit for 24 hrs. On October 3rd, they will begin swabbing the casing, once this process is completed, the contractor will perform minimal well development just to clean up the well. When the drill rig is removed, the sound walls will come down.
Widdison Turbine will mobilize to the well site mid October to begin developing the well. Well development is a critical part of producing a good drinking water well. This process will take roughly 35 working days.
The reason well development is so important is that just as the well is drilled, is the best time and opportunity to open up or clean the formations in the aquifers that produce water.
When the rotary drill rig is removed, Widdison Turbine will set up a cable tool rig to surge the well. The cable tool rig uses specialized tools called a surge block and bailer. The surge block fits tight against the interior walls of the casing/screen, similar to the action of a syringe. As the surge block is raised and lowered in the casing it pulls water from the formations of the aquifer and then forces it back into the formations. This surging motion forces water through the formations loosening sediment.
This process will pull any drilling mud and sediment into the casing which can then be bailed or pumped out. Essentially the development process is power washing the formations that produce water. Once the power wash is complete and the water is clear, a pump is installed into the well casing to accomplish what is referred to as the test pump.
Pumping will start at a lower gallons per minute rate (GPM) and progress to something above 4,000 GPM which is what we are hoping to produce with this well. Water will be pumped at a higher rate (over pumping) and then a lower rate, again surging water through the formations. Once the higher GPM is established, a constant rate test is performed for 24 hours to determine what the well is capable of producing or constant rate. This is a 350 to 400 hour process.

The 20 inch diameter well casing is onsite, however, the installation has been delayed while the contractor secures a high quality gravel pack which is a critical component of the well. The shipment of gravel that was delivered failed to meet the required specifications and was rejected.
It is believed that an acceptable gravel pack will be delivered in approximately seven to ten days, at which time the contractor will resume reaming the hole.
Update - September 16, 2022
The gravel pack material has arrived on site and the drilling crew is putting the drill rig back in place. The contractor will begin reaming the hole later next week to a diameter of 28 inches.
This will be followed with the installation of the 20 inch diameter well casing with its screens to a depth of approximately 950 feet and the placing of the gravel pack.
Update - July 27, 2022
The drilling crew is back and will begin reaming the hole later this week to a diameter of 28 inches.
This will be followed with the installation of the 20 inch diameter well casing with its screens to a depth of approximately 950 feet.
Update - July 13, 2022
The drillers are headed home, but they will be back!
Last night the drillers finished water quality sampling. Currently they are filling the 17-1/2 inch pilot hole with pea gravel from a depth of 950 feet to 250 feet below grade. Once complete, they are heading home for much needed time off.
The well site will be quiet for approximately two weeks and then, the drilling crew will be back to begin reaming the hole to a diameter of 28 inches.
This work will include the installation of the 24 inch diameter well casing with its screens to a depth of approximately 950 feet.
Update - July 6, 2022
Well drilling began June 17, 2022. Currently the smaller 17.5 inch diameter pilot hole is at close to 850-foot depth.
Once the target depth of 900-feet is reached, operations will switch to water quality sampling which will take place at various depths. This process is critical to identify the best quality water in each aquifer.
At the completion of the testing period there will likely be a period of up to two weeks without the drill rig in operation. Thereafter, the drilling with the 28-inch reamer will commence and the operation will run 24/7 until final depth is reached.
After the drilling process is complete, well development will begin. This process is very important to produce a productive and efficient well. Well development is completed by test pumping the well for a period of up to 400 hours. Fortunately, this process can be completed during normal working hours. However, the last 24 hours of pumping will be continuous.
From start to finish the total process to drill and develop the well is expected to take two to three months.
Update - June 25, 2022
Well drilling has begun at the northeast section of the Heritage Park site. There is equipment and a tower in that area. The contractor has erected sound walls on the north, east and south sides of the drill site. The drilling for this well will take approximately two to three months and will run continuously, twenty-four hours a day - seven days a week until the work is completed. This well will potentially reach a depth of up to 900 feet.

Well development is completed by test pumping the well for a period of 400 hours. Fortunately, this process can be completed during normal working hours. However, the last 24 hours of pumping will be continuous.
Upon completion this well will assist the water supply for the 10 million gallon buried tank on this site.
Drilling for the 900 foot depth well has commenced as of June 23rd and will run non-stop (24/7) for the next 2-3 months.
Initial Start Up
From June 21st to June 23rd the well driller installed a 40 foot casing at the surface of the drill site.
