Case Study for Customer Location
CO60:
Reservoir or Lake Use:
Called "Reservoir #2", this is a raw water storage reservoir in
front of a potable water treatment plant. It is kept filled with
water that is diverted from a stream a long distance away.
System Overview and Reservoir:
Surface Area is 23 acres; maximum depth at full volume is 33 ft;
minimum depth is 22 ft; average depth is 28 ft; volume is 600
acre feet, or 195 MG. Average withdrawal rate is 1 MGD, so
hydraulic residence time is 195 days. District withdraws water
at about 23 feet deep.
Reported Problem Before Installation:
Taste, odor, blue-green algae blooms and stratification are
major concerns. Actinomycetes bacteria associated with
blue-green algae may be the cause of their problems.
Installation:
Installed in March 21, 2001, 2 units each equal to a SB2500.
Intake hose initially set at about 23 feet initially and then
lowered to 27 feet the following year.
Results:
Reservoir destratified within one month after installation,
maintaining good dissolved oxygen (DO) throughout the water
column. There were no odor complaints in 2001, the first year in
the last four without reported customer complaints. At that time
(2001) management felt that they had found a solution to their
problems. That assessment has not changed since. In fact, after
4 years of service the manager remains very happy with the
SolarBees. Taste and odor problems continue to be controlled,
and they are interested in SB10000 high flow units when they
increase reservoir capacity. They also report that fishing has
improved noticeably since the SolarBees were installed.
