City of Adel issued the following announcement on June 18
Progress On New Water Treatment Plant
The City of Adel’s new Water Treatment Plant has been under construction since July 2019.
- The project is tentatively on track for Spring 2021, though many factors could affect this target.
The City is in the process of designing or constructing seven major water infrastructure projects totaling approximately $24.87 million.
- New Water Treatment Plant (under construction)
- New Raw Water Transmission Main (substantially complete)
- Water Main Replacements on Rapids Street and Bryan Street (complete)
- Two New Wells (substantially complete)
- New Ground Storage Reservoir (bidding)
- New High-Zone Water Main (designing)
- New High Service Pump (designing)
- Of the total cost, USDA-RD has provided approximately $3.5 million in grant funds.
- The projects have received highly competitive loan terms, including historically low financing rates.
Water Watch
Since mid-June 2020, water usage has been trending upward with the hot and dry weather.
As in previous years, we expect a Water Watch will be needed this summer, likely sooner than later.
More details will be provided when a formal Watch has been issued.
Lawn Irrigation
For Adel Water customers, please limit your lawn watering or irrigation to the hours of 8:00 p.m. through 8:00 a.m.
- When you water your lawn during daytime hours, the majority of water is lost due to evaporation.
- Even-numbered addresses should water only on even-numbered days.
- Odd-numbered addresses should water only on odd-numbered days.
Existing Treatment Plant
With increased water usage this summer, it has become necessary to take the existing water treatment plant’s softening system offline until usage declines.
- This action reduces a production bottleneck from backwashing.
- The plant’s softeners were taken offline ahead of and during previous Water Watches.
- The existing softeners have exceeded their design life and have been repaired previously with little gain. Additional repairs would be costly and provide minimal benefit.
- With design, DNR review, bidding, and letting requirements, it is highly likely that any fixes to the softeners would not be ready until after the new plant is online. That is, the new plant will be operational and will take over before any fix on the existing plant could be implemented.
The new plant’s Reverse Osmosis Membrane softening process will be more efficient at removing water hardness and will eliminate the chloride by-product waste that the existing softening system creates.
- The new plant will also have increased production capacity, which is a bottleneck in the existing process.
While frustrating and not aesthetically pleasing, hard water is not recognized as a health hazard.
Some customers have private, in-home softening systems.
- While the existing plant’s softening system is offline, please adjust your in-home softening system settings to 23 grains (400 mg/l), which is the average hardness level at the treatment plant without softening. Hardness levels may vary slightly in the distribution system.
- As with any other home maintenance, it is understandable that adjustments or maintenance on these systems could be delayed or forgotten. If that is the case, the customer would not be able to take full advantage of their private softener.
