NY66:
Reservoir or Lake Use:
One of five raw water reservoirs supplying a town's drinking
water.
System Overview and Reservoir:
Surface area is 7.5 acres; volume is 1.4 MG; maximum depth is 15
feet when full; average depth is 7 feet. The lake is relatively
long and narrow with an island in the middle.
Reported Problem Before SolarBee Installation:
The reservoir had been plagued with Eurasian watermilfoil (EWM)
infestations (too thick to get an oar through) and blue-green
algae blooms for at least 20 years. It could not be used for
drinking water due to taste and odor problems associated with
blue-green algae blooms and organic buildup at the sediment
layer. Water quality was unsuitable even when mixed at a 1:20
ratio with water from other reservoirs.
SolarBee Installation:
Date: July 2002. Two SolarBee SB10000 solar-powered units, one
installed at each end of the lake with the island in between;
intake hoses were set at 7 ft and 7.5 ft. Installers reported a
thick crop of EWM growing throughout reservoir.
Results:
By January 2003, owner reported significantly improved water
clarity and the ability to use water from the reservoir for
first time. By June 2003, owner was able to maximize the use of
reservoir water, with EWM growth dramatically reduced for first
time in memory. Water quality remained excellent throughout 2003
without EWM infestations. By August 2004, EWM was found only in
isolated traces in protected areas, and remaining plants had a
sickly, yellowish look consistent with nitrogen deficiency (EWM
uses ammonia-N rather than nitrate-N, and SolarBee circulation
apparently promotes the removal of ammonia from surface
sediments through oxidation and transport). Operator stated that
water quality improved even further in 2004 than observed in
2003, with water clarity increasing to 3 feet. Water quality and
clarity remained very good throughout 2005, while EWM continued
to be kept under control. The operator is very pleased with the
benefits of SolarBee-induced circulation.
