Global Positioning System (GPS):

Geographic Information Systems (GIS):

Mapping Services through IRWA:

GPS is a navigation system made up of anetwork of 24 satellites, placed into orbit bythe U.S. Department of Defense. Thesesatellites circle the globe twice a day in avery precise orbit, and transmit signalinformation back to earth. GPS receiverstake this information and use triangulationto calculate the user’s exact location.

GIS combines mapping software withdatabase management tools to collect,organize, and share many different types ofinformation. GIS can store, display, andhelp your utility interpret virtually all theimportant attributes of your system.

Through the implementation of GPS & GIStechnology, IRWA can effectively producehard copy and digital maps, to be utilizedby system personnel for water and/orwastewater facilities in the state. With thisnew service available from IRWA, utilitiescan attain new and accurate maps to bettermanage their infrastructure assets.

What does the system receive?

IRWA will generate printed maps and a digitalmap file for your system. The printed maps canbe large-scale wall maps, showing majorfeatures with the desired layers (aerial photos,streets, topography, etc.). The printed maps canalso be generated into a map book format. Themap book is a bound 18" by 24" book of high-detail maps printed at the best available scale.

The digital map file on a CD, can be viewedand printed with free software that IRWA willprovide. The software allows you to click on awaterline with a leak and highlight whichvalves need to be closed to isolate the line.There are also tracing features to show thedirection of water flow, and other usefulfeatures.

CostPayment for services is determined by acharge per each system feature locatedand mapped, based on the type. Theseamounts will be discussed with systempersonnel, and documented before thestart of the project.

The digital map on a CD is included in theset feature location cost. The amountcharged for a Map Book will be $50 plus $5per page; and a wall map is a flat $100 feeeach. (Note: Hardcopy maps areoptional.)

Accurate and up to date system maps:

Our mapping technician will work withyour system personnel to develop precisemaps of your infrastructure.

This is also true for wastewatersystems in locating manholes, lift stations,treatment plants, etc. Additional details onthese features can be added when gatheringthe data, such as line size, date ofinstallation, or manufacturer. Incorporatingthis kind of data allows you to monitor andevaluate your system at a whole new level.

IRWA will input the data from the fieldalong with background layers such as aerialphotography and create high quality,detailed maps of your system. At the end ofthe project, all data and the maps will beowned by you for use in the future.

The datacollected in the field will show theplacement (to within one foot in most cases)of water features such as master meters,main valves, hydrants, tanks, wells, as wellas others.

How does the program work?

Just contact IRWA and express your interest in amapping project. We will then do a shortpresentation for your governing body and a pre-assessment survey to determine project needs.

IRWA will provide a scope of work, a costestimate for the data collection and mapproduction, and a service contract. Theestimated cost is based on the number of datafeatures to be collected and time to produce themaps.

After the contract is signed, the next step is tocollect data in the field using a Trimble GPSreceiver, which is one of the industry’s bestThe accuracy of this equipment is less than onefoot of the actual location of the feature.

System personnel accompany ourmapping staff in the field to ensure we collectall the features you want. And all pointsneeding location, be accessible to ourfield technician.

Next, we post-process and digitally correct alldata collected to ensure accuracy. These datapoints are input into a GIS program to create avariety of map products. IRWA will utilize topGIS software to create hardcopy and digitalmaps to the utility's specifications.
