The Duchesne Tunnel continues to flow during the winter, so the Association has to continually inspect the entire system.  Association staff inspects the radial gates at the Duchesne Diversion and ensures that the forebay and tunnel remain free of obstructions such as heavy ice and debris.  They also inspect the Broadhead Diversion pipes and machinery to maintain its continued flow.  Preventative maintenance is also completed, such as lubrication of machinery, painting, and replacing wear parts such as radial gate cables and seals.

Weber-Provo System

The Weber-Provo Canal continues to flow during the winter, so Association staff walks the entire canal and inspects it for leaks and obstructions.  In the Weber-Provo Diversion, Association staff has to clean out spring runoff debris from the forebay in order to ensure that ice will not build up and obstruct important mechanisms.

Deer Creek Dam & Reservoir

Due to the significant value and important function of the Deer Creek Dam, the Association’s operators inspect and maintain the dam daily.  They perform preventative maintenance on tube valves and penstocks, and ensure that the radial gates are working properly.

Deer Creek Power Plant

In order to prepare for winter at the power plant, each of the two turbine generators is taken out of service one at a time, cleaned, painted, and preventative maintenance is performed.  Approximately every 15 years a major service and overhaul on the turbine generators is performed.

Provo Reservoir Canal

In order to prepare for winter, Association staff turns the canal off and drains it, then inspects the entire canal for leaks and debris.  Each of the four siphons is drained as much as possible, and the remaining water is pumped out.  Damaged equipment is taken to the shop to be repaired.  Screens are placed in front of each siphon to prevent debris from blowing in during the winter months.  The siphons are inspected for leaks and cracks and repaired as necessary.

Jordan Narrows

To prepare for winter, Association staff inspects the siphon and penstock at the Jordan Narrows and checks for any cracks or leaks.  The turbine pump and valves also receive preventative maintenance and inspection.
