Services
Expert diagnosis and repair of control panels
and associated equipment, including flow meters, recorders, automatic
dialers, ultrasonic sensors, fluid level transducers and
generators.

Programming
Our staff is
very familiar with a variety of Programmable Logic Controllers,
Variable Frequency Drive Units, Flow Meters, and Level Controllers.
We can assist you in establishing operating conditions to meet your
requirements.
SCADA
A Supervisory Control And Data Acquisition
system can benefit customers by allowing them to remotely receive
status and alarm notifications from water plants, sewer plants,
and lift stations using the latest Telemetry technology. Plant sites
may be miles away from the office. Systems are available which use
no telephone line or hardwired connections. Let us talk to you more
about this advanced option!

Water Tank Substitution
In areas covered by only one Water Tank we are
able to supply water to your customers without anyone being aware
that the method of regular delivery had changed.
With the use of a Variable Frequency Drive sized
to match the horsepower of your pumps, we can take your tank off-line
and still provide your customers with the same water pressure to
which they are accustomed.

Flow Meter Calibration
Due to the requirements of the Texas Natural
Resource Conservation Commission (TNRCC) most flow meters
at Wastewater Treatment Plants must be calibrated
and certified yearly. We have technicians on staff who are qualified
to perform this task.
Our calibration rates are
reasonable. We charge $275.00 to $350.00 for checking and certifying the
calibration of a flow meter. A nominal mileage charge may apply.
Additional flow meters checked and certified on the same trip are
discounted $50.00 each. Please call for details.
If adjustments are necessary there will be extra
charges.

Variable Frequency Drives
(VFD)
&
Precision VFD Controllers

A VFD can control the amount of power that a
blower or rotor motor uses to supply Dissolved Oxygen to aerate
waste water. A PLC interprets received data and then varies the
RPM of the motor/s used in order to maintain the desired D.O. reading.
The immediate cost savings in energy will be considerable. An added
benefit is extension of the life of the motors.
Temporary use of a VFD during a water tank inspection
can save having to run a booster pump at full capacity and save
a huge electricity waste due to water pressure issuers. To eliminate
this waste, a VFD is connected to your existing pump to control
the water line pressure by varying the RPM of the pump as needed
to maintain a stable pressure.

Tailored Preventive Maintenance Inspection
Program
We now offer our customers the benefit of a
preventive maintenance program. The best way to eliminate costly
repairs is to prevent the equipment from failing in the first place.
Budgeting for repair and maintenance is very difficult. You are
trying to predict what will break down and when. We will review
the condition of your equipment and give you a detailed report of
our findings, with our recommendations. Everyone involved in planning
for the year can have a better understanding of what repairs need
to be budgeted. There is no maintenance program that will insure
your machinery will not fail without warning, but the procedures
we have created combine our expertise and the use of instrumentation
to help identify failures that need immediate repair, as well as
accurately flag potential problems.
Typical PM Inspection Process:
1.
Motors
-
Check resistance of
winding insulation
-
Check measurement of
voltage and current on each inspection
-
Perform visual
inspection
2. Motor
Starters
-
Check voltage drop
across each leg of the starter
-
Check termination of
conductors for proper torque
3.
Circuit Breakers
-
Check voltage drop
across each leg of the breaker
-
Check termination of
conductors for proper torque
4.
Pumps and Gear Boxes
-
Check lubrication levels
and take samples, if desired
-
Perform a limited
thermal scan*
-
Perform an audio/visual
inspection**
*
Thermal Scan:
A
scan of all components in the control
systems for any abnormal temperature
readings. For pumps and motors this will
help to identify problems with moving parts.
**
Audio/Visual Inspection:
Inspection of all system components to find
worn parts and loose connections. We also
include in this inspection listening for
faults which show themselves through
vibration.
Why
Preventive Maintenance?
The customers served by a public utility
have little patience and less understanding
when the water tap is dry or the sewer does
not flow, but major breakdowns can be
prevented.
