You may be surprised to know that, in many ways, the City of Redmond Wastewater Maintenance Division is a front-runner when it comes to the use of existing and emerging technologies. On a daily basis, Wastewater staff use a wide variety of hardware and software to efficiently operate and maintain City infrastructure. Listed below are just a few of those technologies.


SCADA is an acronym which stands for Supervisory Control and Data Acquisition. Quickly defined, SCADA is a computerized system which monitors (and in some applications, controls) infrastructure.

Redmond's Wastewater Division makes use of this technology to monitor 23 lift stations remotely. One advantage of using a SCADA system is the transfer of information to and from various sources is near instantaneous. This allows staff to monitor lift stations in real time and, with the knowledge delivered by SCADA, operators can make quick decisions in a number of circumstances.
With data constantly being digitally recorded, it also provides staff an opportunity to look at trends from a historical perspective. This information becomes an invaluable asset when planning preventative maintenance and corrective actions.


GIS is an acronym which stands for Geographic Information System. GIS is a system which integrates hardware, software, and data for capturing, displaying, managing, and analyzing all forms of geographically-referenced information.
The City of Redmond GIS allows Wastewater Division staff to visualize, question, interpret, and understand data, allowing us to efficiently plan for growth while continuing to maintain our existing infrastructure.

Granite XP

Granite XP software allows city staff to complete digital video inspections of underground wastewater pipe through the use of a computer on the Wastewater Division’s Closed Circuit Television (CCTV) truck. These inspections allow staff to determine what maintenance procedures are necessary for each segment of wastewater pipe. In most cases, no further action is needed. In some cases, an inspection can reveal work that needs to be done preventatively to save time and money. When damage is documented, the video inspections are also reviewed by City engineers so that pipe segments may be included in the wastewater capital improvement program.
