|Details:||Reasons for Water restrictions
John provided an update on the status of their water restrictions.
The reservoir hasnít been dredged in the past years or so and the system has lost two thirds of water storage capacity due to sediment buildup. The draw down was greater than the recover due to the run time of the plant. Their water loss is around 30% and doesnít help the situation, the system loses about 2 ft at night and only make about 1.4-1.5 ft during the day (8hrs), so they run 12hrs most days to keep up with demand. When it rains for half an hour or more, the treatment plant remains off-line until the turbidity drops. Sometimes this may take two days, with usage around 4ft in a 24hr period. The city only has one storage tank with a volume of 1 million gallons, this is approximately 6.5 days or so of water. The system found that there are a number of customers with well above average water usage. The system has upgraded both of the distribution pumps and the plant in order to increase water production from 250 to 300 GPM. A new tracer study is required for the increase in flow rate (above 10 percent of the max flow used in previous tracer study). These are the main reasons the city had to put in place a water curtailment measure and restrictions. The city has to provide water to the current customers and thus they are not allowing any new connections until they can support them. The City adopted the water restrictions under Ordinance No. 2022-04. This Ordinance was enacted by the City on Feb 17, 2022.
Next steps: John will be conducting a new tracer study. Civil West was contacted to provide assistance.
