Trino Pedraza, New Braunfels Utilities - Speaker at the marcus evans Water & Wastewater Management Summit 2012, held in Summerlin, NV, May 3-4, 2012, delivered his presentation on the topic Taking the Bull by the Horns with Reliability Centered Maintenance

1. NBU S i i F E ll
NBU Striving For Excellence
•NBU was established in 1942 as an Electric Transmission and Distribution System
•In 1959 the City of New Braunfels transferred the Water and Sewer systems to NBU
•NBU employs over 200 people in three lines of business: Electric, Water and
Sewer/Wastewater

2. •The NBU Water System has the
benefits of two water supplies that
b fit f t t li th t
NBU Service Area
serves 24,000 water connections
through 454 miles of water pipe:
•Ground water pumped
through municipal wells from
th h i i l ll f
the Edwards Aquifer
•Surface water from the
Guadalupe River treated at
our surface water treatment
f t t t t
plant
•The NBU Sewer/Wastewater
system serves 20,300 sewer
connections through 345 miles of
ti th h 345 il f
sewer pipe connected to three
wastewater treatment plants
•The NBU Electric System serves
28,000 connections through 770
28 000 connections thro gh 770
miles of overhead and underground

8. Water Distribution Maintenance
Valve and Hydrant PM Program
y g
Ensures valves and hydrants are operational, not leaking and
in proper position
Our team aggressively PMs over 750 valves a year
This represents 7.5% of the system
The information gathered is stored in our CMMS /GIS systems
The information gathered is stored in our CMMS /GIS systems

Water Distribution Maintenance
Today the leak detection team consists of a 3 man crew armed
with state of the art leak detection equipment
q p
The crew uses 60 programmed data loggers to monitor an
area
If the data loggers register a possible leak, the team will use a
correlators to pin point the leak
Once the leak has been found the team will repair the leaks
Once the leak has been found the team will repair the leaks
and capture the leak attributes

13. Why CIPP
Pros Cons
• Trenchless Technology
Trenchless Technology • Reduces pipe
Reduces pipe
• No spoils diameter slightly
• Reduces Infiltration • Very strict and exact
