Main Takeaway: 60% Reduction in Seepage and Water Savings of 1428 Acre Feet per Season

Billings Bench Canal

Key Findings


To treat the 2.7 mile reach of the Billings Bench Canal, a sample of water was taken from the canal to check for turbidity. This is an indication of the level of suspended solids in the water which can be dropped out and used for sealing the canals. The measurement showed the turbidity to be 50 NTU, about half of what is desirable (100 NTU) to generate a good bed of solids for sealing. Since the canal company had enough CanalSentryTM for two applications, It was decided to proceed with the application to see how effective the product would be at sealing the canal at these low turbidity numbers.


Seepage rate was reduced from 10 cubic feet per second to 4 cubic feet per second after CanalSentryTM was used. CanalSentryTM application reduced seepage by 6cfs.

Key Findings

The water savings from using CanalSentryTM to reduce seepage in the 2.7 miles of the Billings Bench Canal was 11.9 acre feet/day and a 60% reduction in seepage.
