What is GIS technology? 
A Geographic Information System (GIS) is an information system that allows for mapping, querying, modeling, and analyzing data based on geographic location.

Maximizing GIS technology to maintain reliable 
water and sewer services.
Our commitment to being the best-in-class small utility includes making the most of the advanced technology in the water and sewer industry. Our staff uses geographic information systems (GIS) software that seamlessly integrates information across multiple areas of the organization including customer service, finance, operations and maintenance, field services, and administration. GIS is a powerful tool that gives us the ability to not only accurately map the locations of all water and sewer assets, but also add information to manage and analyze them. In other words, we use GIS as a mapping system as well as an asset management system.

Being informed, efficient, and fiscally responsible.
What sets GIS apart from other technologies is the ability to assign information to a specific geographic location. It is important for us to know where everything in our system is physically located. This includes items like fire hydrants, valves, wells, and under-ground pipes. However, taking that a step further, GIS gives us the ability to track information such as the current condition, replacement value, and estimated lifespan of those components. The more we know about the systems we operate, we better can plan for and the faster we can respond to situations.

GIS touches many disciplines within the District. For example, field technicians pull up customer information while out in the field, enhancing customer interactions and providing faster service. Inspectors use mobile devices to access electronic construction drawings while conducting annual inspections. Engineers analyze distribution system conditions to understand how changes to the system would affect other areas of the system. These are just a few examples of how GIS technology helps us increase accuracy and efficiency, save time and money, and improve project management.

Clean water is always there because we're always here.
For more than 75 years, we have provided a safe and reliable water supply that has supported our communities. By maximizing GIS technology in our operations, we can make sure that we continue to be that reliable source of water and sewer services for future generations.
