Energy
Program
Sponsored by: Department
of Environmental Quality

Conserve energy,
money, and water by following
these water and energy saving tips, and you will see a difference in your next
water bill.
1. Make sure water is off while you shave
or brush your teeth - 4 to 10 gallons saved per day.
2. Taking a bath? Fill the tub half full - 16 gallons saved per day.
3. Five minute showers - 21 to 26 gallons saved per shower.
4. By washing a full load of dishes in the dishwasher or washing a full load of
clothes in the washing machine - 15 gallons saved per day.
5. Install a low flow shower head - 20 gallons saved per day.
6. By filling two (2) plastic one quart bottles with sand or gravel, and placing
them in the toilet tank you can reduce the amount of water
used per toilet
flushing - save 10 or more gallons per day.
7. Repair Leaks as soon as they occur.
a. 1/32 inch stream stopped - saved 6,166 gallons per month.
b. 1/16 inch stream stopped - saved 24,700 gallons per month.
c. 1/8 inch stream stopped - saved approximately 99,000
gallons per month.
d. 1/4 inch stream stopped - saved approximately 400,000
gallons per month.
NOTE: Leak sizes and gallons lost per month are at 60 PSI.

Routine
toilet tank inspection |
Check tank water level:
If the water in the tank is too high, it will spill over into the overflow
tube and be wasted. The correct water level is about 1/2 inch to 1 inch
blow the top of the tube. To lower the water level either adjust the screw
on the ball cock or bend the arm down until the correct level is achieved.
Repairing Toilet Leaks:
1. By removing the lid from the toilet tank, drop in some type of dye
into the tank, wait 5 minutes, if the dye appears in the toilet bowl, there is a
leak.
2. Check your flap or flush valve to make sure it is reseating properly.
If it is worn or corroded, it needs to be replaced.
3. If you have to jiggle the handle to get it to stop running, check the lift
chain or guide to make sure it is not hung up or out of alignment.
4. Check the water level in the tank; if the water level is too high in the tank
it will spill over into the overflow tube and be wasted.
5. Ball cock runs: If water doesn't shut off at all, replace the ball cock
and flapper, or replace toilet with a new 1.6 GPF (gallons per flush) toilet.

Good reasons to conserve water |
In attempt to help educate you on how to save
water and energy without sacrifice and cut use in your home by up to 50%. Not
only do you conserve water, a precious resource, but you can save energy and
money, and it's something every American can do to clean up the environment.
1. Clean up the environment by
saving water and energy at home. Using less water means less chemicals to
process dirty water, less sewage, and less energy required to heat water.
2. Rate increases of taxes and utilities will be held down, allowing your
utility system to minimize the wear and tear of its existing plant equipment.
3. Save up to 47,000 gallons of water per year, not to mention money saved on
your utility bill.
4. Faucet leaks big or small, dribble away water and can be costly. A leaky
faucet can waste up to 20 gallons per day. If the water is hot, you are using
energy to heat it, which can be expensive.

Energy Efficiency
Energy efficiency in a treatment
plant requires extra effort on part of the staff.
It requires a commitment
from the management, and the ability to look ahead.
There are several steps to achieving this goal:
1) Establish maintenance programs
2) Conduct energy audits
3) Implement audit recommendations
4) Co-generation
5) Improve equipment and controls
6) Understand electric rates
Energy costs make up about 30% of the budge, and in the next 20 years will
increase by 34% to 45%.
Without steps to reduce system consumption now the cost
will cripple most small utilities.
Our goal is to lower our dependency on energy and increase our awareness of more
effective ways to do the same job more effectively.
Establish Maintenance
Programs
Regular and preventive maintenance
is one of the first steps of any well-run plant, which allows the operator to
know what is happening in his plant. Regular testing of equipment will tell you
if the equipment is operating as it should. The manufacturers recommended
maintenance and inspection guidelines are the best information on performance
testing.
Testing or running redundant or backup equipment on alternative
fuels or at off-peak hours is a way of saving electricity.
Tip #1
When testing emergency generators,
instead of letting them run idle use them to power lift stations during testing.
Conduct Energy Audits
Energy audits are not as complex as
they sound. They require time and commitment from everyone. Audits may include a
review of operating procedures, plant walk through, modification examination,
and cost assessment.
These audits are sometimes subsidized by power
companies and can be performed by plant personnel.
Audit Recommendations:
-
Conduct periodic pump test
-
Run generator during testing and
peak load
-
Install or replace with high
efficiency motors
-
Replace oversized motors during
repairs
-
Implement as many changes as
possible
Implement Audit
Recommendations
Starting the measures outlined by
the audit report can be a slow process, particularly if large investments of
capital are required.
By prioritizing the list, changes can be made as
monies become available.
Rebates or other incentives can be factored in long
term financing.
Load management measures and Energy Management Systems are ways of shifting or
saving energy usage. These measures require planning. The purpose is to stagger
equipment usage, monitor process levels and use alternative fueled equipment.
Co-Generation
The operation of backup generator
during peak demand periods and during testing can help reduce energy costs by
20%. Instead of just letting the generators run for 4-6 hours with no load, use
them to operate lift stations, pumps, or blowers. This takes a little
manpower, but saves on electricity.

Improve Equipment and Controls
Improving equipment and the controls
for that equipment is easier than you think. It does not require replacement,
but changes to operation and maintenance. By making the equipment operate
properly you also make it operate more efficiently: replace worn belts, adjust
belts to proper tension, change to fine pore diffusers, check and replace worn
bearings o aerators. Check pump operations for proper operation, replace leaking
seals, worn impellers, and restrictions. Replace burnt motor and pumps with high
efficiency units. Check to see if adjustable speed motors and controls would be
beneficial, and make sure the pump curve is correct for your application.
1) Check for leaks in air system
2) Check for leaks in pump seals
3) Test pumps for proper operation and sizing
4) Replace motors and pumps with high efficiency units
5) Make as many improvements as allowed
Understand Electric
Rates
Understanding electrical rate
structures is probably the toughest part of the job, but there is help. Contact
your electric company and ask to have a representative come out and go over your
rate structure. Understanding peak loads, time of day rates, KW usage and
maximum connected load charges will help reduce your cost. Some utilities have
what is called a UTILITY-INITIATED MANAGEMENT PROGRAM. There may be incentives
or special rate programs to help reduce energy cost for the plant.
