4. 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are very costly due to the response time to leaks  Resulting in billions of cubic meters of water is lost every day in outdated and unsupervised water distribution networks around the world.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. Project # 1.7

5. Sponsored by SENSCO Solutions  SENSCO’s 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. Project # 1.7

12. Project Deliverables  Integrate the Water Leak Detection Sensor with Audacity, ClearBlade, and LabVIEW  Research and implement effective detection algorithms for informalities  Generate a Spectrogram from any audio file  Test whole system at Pecan Street test facility Project # 1.7

13. 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 Project # 1.7

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. Project # 1.7
