Subject: Electric & Water Production
The production report in the financial section, reflects monthly electric and water
statistics. In August, we established new consumption peaks for this year The electric
peak occurred on August 18, with an approximate non coincident peak of 40,432 kw.
Monthly sales will pushing 18,000,000 kwh. We are still awaiting the final numbers
from Great River Energy. Our electric system responded very well. The landfill
generator was producing at capacity as usual. The wind generation was barely producing
at 46 kw also as usual.
Attached is an article from August 31, 2003, Star Tribune toting the 1,000 mw of power
in Minnesota. Articles like this, lead people to believe that wind power is the solution to
power shortages. Our 660 kw unit only produced 46 kw when we needed it. I wonder
what the 1,000 mw produced at the monthly system peak.
On August 18th, we pumped 4,477,000 gallons of water which is our yearly high. Total
August pumpage was a little under 120,000,000 gallons. Our all time system peak
occurred in July of 2001 with a peak day of 5,323,000 gallons and monthly pumpage of
122,249,000 gallons. It would appear our sprinkling restrictions are effective to some
degree.
When we pump our wells hard, as we did in August, we get concerned about the ground
water levels and long term ground water depletion. In 2002, your staff on a monthly
basis, started measuring static and pumping levels in our well. We are looking for short
term and long term trends in ground water levels. The attached spread sheet and graph
reflects the results to date. We do drop the static and pumping water levels in some of
the wells by as much as 10 to 20 feet during periods of high pumping, but the water level
appears to recover during off peak season. We do not want to lower the water level to the
point where the ground water does not recover, or expose the pump to air instead of the
pump being submerged.
In early morning on Labor Day, vandals opened approximately 30 fire hydrants in the
Trott Brook, Trott Brook South, Kliever Lake Fields, and Park Pointe area. This drained
about a million gallons from our new water tower before staff rectified the problem. Had
this happened on a peak water usage day, we would have been in serious difficulties.
This act also compromised the fire fighting abilities in this area. These types of acts are
also very difficult to prevent.
