Project # 1.7

Project MotivationThe 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in outdated and unsupervised water distribution networks around the world.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

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

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.
