Main Takeaway: 57% Reduction in Seepage and Water Savings of 95 Acre Feet
Key Findings
Conditions
To treat the 2.1mile of 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 less than 50 NTU, about half of what is desirable (100 NTU) to generate a good bed of solids for sealing.It was decided that additional turbidity needed to be added to the water to effectively seal the canal, so two truck loads of sediment was brought into the reach and strategically dispersed so it could be added during the treatment.
Observations
To validate the flow numbers after the application, a complete set of measurements were made after the application. After treatment with CanalSentryTM, The flow rate at the upper reach was measured at 3.2 cfs and the flow rate on the lower reach was measured at 2.9cfs. A loss rate of 0.3 cfs. Before the application this reach was losing 0.7 cfs. Therefore the application reduced the seepage by 0.4cfs.
Key Findings
The water savings from using CanalSentryTM to reduce seepage in the 4.4 miles of RockyFord Highline was 7.9 acre feet/day, a 64% reduction in seepage.
