Hot Sulphur Springs Water Tank
Roosevelt Ave.
Hot Sulphur Springs, Colorado

Blasting will commence on: Monday, July 5, 2010
Blasting will continue through: Friday, July 16,2009

Prior to each detonation there will be a five-minute and then a one-minute pre-blast warning signal. After each blast there will be an all-clear signal.

We ask that, upon hearing these warning signals, residents and occupants ofnearby businesses, do not approach the blast area.

Blasting results in a certain amount of noise, air movement, and tremors. However, these effects should not be cause for concern, as all blasting is done in accordance with established national, state and local standards and regulations that govern the size of each detonation to ensure safety to structures.

Tough Rock will Require Blasting

The construction crew ran into unexpectedly hard rock at the tank site last week,so plans are being re-worked to use explosives to help excavate the bench for the new water tank. Garney has assembled the top-notch team of Yenter Construction to do the drilling and blasting under the guidance of Gordon Reavy.

By using modern methods for precise blasting, the effort must break hard rock while protecting the existing water tank some 20 feet away. The closest homes and other structures should not feel any movement. Town Staff will put notices up around town and will talk to neighbors. They will also have seismic consultant Sara Nation available for discussion and for documentation of existing conditions and actual blast results.

Schedule:

Week of 28June drilling on site

July 1 evening informational community meeting at ToHSS Town Hall with blasting consultant Sara Nation

July 5-7 blasting

River is Raging & the Project Looks Great!

Besides Hot Sulphur Days last weekend, which was a real hoot, the big news in our project area is the raging Colorado River. Flows of up to 2,300 CFS were measured at Windy Gap USGS Gage upstream, and flooding along the river was common. We are happy to report that our water intake area and associated river restoration is handling the flows just fine.



The first photo looking upstream shows river flow over the boulder weir and the intake piping without hardly breaking the surface. The low-profile design is working properly with flood flows passing over the structure without increased shear stress. The riparian restoration work the was done has narrowed the river channel as seen through the shrubs on the second photo and is also holding up quite well. Nick Mezei of the US Army Corps visited the project on June 8 as part of the seasonal monitoring. We will be evaluating the restoration work throughout the year to see if there is scour or sedimentation.
