Project Motivation

• The problem
• Existing Leak detection systems of water
  municipalities are very costly due to the
  response time to leaks
• Resulting in billions of cubic meters of water is
  lost every day in outdated and unsupervised water
  distribution networks around the world.
• Why is this important?
• Water is the most important resource required to
  sustain a healthy population.
• The Water Leak Detection Sensor Sonic Spectrogram
  project hopes to help greatly reduce the response
  times to leaks by creating a graphical
  representation of the acoustical activity within
  the pipes it is monitoring sending alerts to the
  user real time at start of the leak.

Sponsored by SENSCO Solutions

• SENSCOs Water Leak Detection Sensors Sonic
  Spectrogram project can be implemented into any
  water distribution network, instantly providing
  improved response times to leaks through
• Instant leak detection
• Details of the leak and its location
• SENSCO developed and provided the Water Leak
  Detection Sensors (WLDS) and the Bridge Unit.

Roles and Responsibilities

• Team Member Haleigh Walker
• Research comparison algorithms
• Coding support
• LabVIEW implementation to display spectrogram
• Integrating data from analytical server to
  LabVIEW interface.
• Provide technical guidance through suggestions
  and advice
• Test the WLDS module and Bridge Units
  Specifications

14
Constraints

• Types of pipes used and the type of earth
  surrounding a particular pipe.
• The four main types of pipes in San Marcos
  include cast iron, ductile iron, asbestos
  concrete, and PVC each of these having unique
  properties as to how far it propagates and
  dampens sound vibrations.
• Depending on the type of earth which will
  surround a given WLDS module, some types of earth
  may cause more dampening than others. Before any
  pipe can be excavated, or any WLDS modules
  placed, a range of permits must be acquired from
  the proper authorities.
