Rainwater Harvesting

Tucson Water Harvesting Incentives Program Workshop


Southern Arizona Rain Gutters (SARG) is now teaching Rainwater Harvesting Incentives Program Workshops. See details below to register for a class and to get assistance planning and installing a rainwater harvesting system for your site.

WHAT IS TUCSON WATER’S WATER HARVESTING INCENTIVES/REBATE PROGRAM?

Tucson Water wants to assist its customers to install water harvesting systems in order to reduce the amount of drinking water being used to water plants. To learn more about Tucson Water’s Single Family Residential Rainwater Harvesting Incentives/Rebate Program, go to Tucson Water’s rebate website at http://cms3.tucsonaz.gov/water/rwh-rebate

HOW MUCH IS THE INCENTIVE/REBATE FOR?

Incentives/rebates are available at two levels, and range from up to $300 to up to $2000. For a summary of the requirements see Water Harvesting Rebate Requirements.pdf. For additional details go to http://cms3.tucsonaz.gov/water/rwh-levels SARG has prepared a summary of the rebate requirements and associated plan requirements (see Water harvesting rebate requirements.pdf). An example water harvesting plan shows the items needed to apply for a Level 2 rebate (see Example level 2 WH rebate plan.pdf). A blank template is provided to fill in your specific plan information and calculations (see Blank level 2 WH plan template.pdf)

WHAT SHOULD I BRING TO THE WORKSHOP I‘VE REGISTERED FOR?

Please bring the following to your water harvesting rebate workshop:

1. Bring calculator and drawing supplies including ruler, 8-1/2 x 11 white paper, pencil, eraser, pen, etc.

2. Bring your Tucson Water bill showing usage for the last year

3. Bring 3 copies of an aerial photo or plot plan showing your site’s property boundary, house and location of major vegetation. To download a free aerial photo and get measurements, follow the instructions below.

4. On one copy of your aerial photo or plot plan:

a. Use arrows to draw the direction water flows on the ground and on your roof.

b. Show the dimension of roof areas or other hardscape (patio, driveway, etc) that you may want to harvest rain from.

c. Note trees, shrubs and other major water-using vegetation at their site. How is this watered now? Note plants you want to add to their site and where you might want to put them and how you want to water them

HOW DO I GET AN AERIAL PHOTO AND MEASUREMENTS OF MY SITE TO BRING TO MY WORKSHOP?

1. Go to the City of Tucson Map Center at http://cms3.tucsonaz.gov/mapcenter/

2. Click on the third map down "Stormwater Map (Hydrologic Data and Wash Info). Click "I agree" to the disclaimer

3. Zoom into the part of town where your site is by either clicking on the "+" magnifying glass then clicking on your part of town over and over until it keeps zooming in and you can about where your house would be. OR, go click on "FIND," in the upper menu bar, then click on "ADDRESS" and fill in your street address (NOTE: this feature doesn't work for me on my MacIntosh, with Safari search engine, but it might work on a PC computer with internet explorer)

4. Once you get pretty close to where your house is, turn on the aerial photograph layer by clicking on "MAP" on the top menu bar. Select "Table of Contents." You will see two major headings: "Stormwater" and "Base maps and Aerial Imagery." Click on "Base maps and Aerial Imagery." Choose the 2010 Aerial Image (note....you can also see what your site looked like in other time periods by clicking other years). Now you should be able to see individual houses, streets, trees, etc.

5. Center the screen image on your land and house by clicking on the "hand" and then clicking on the image to move it around until you can see your lots lines and house. You can zoom in farther or zoom out farther using the + or - magnifying buttons.

6. Now click the print command. You may want to change the orientation of the image on the print page to get the biggest picture possible. Print 3 of these out now. You might also want to save this as a pdf so you have it on your computer for later use.

7. To get measurements of your house and property lines, go back to your house on the screen. Click on "TOOLS" on the menu bar, go down to "MEASURE TOOLS" and over to "MEASURE LINE" and click on that. Now go back to the image, click on one corner or your roof then double click on another corner of your roof, going in a straight line. A green line will appear along this roof line. If you put the arrow over the green line, you will see the measurement written on the screen. Write this measurement down on one of the copies of your aerial photo. Keep doing measurements like this for each straight line of your roof, and for your lot lines. Unfortunately, you have to click TOOL/MEASURE TOOL/MEASURE LINE before you click on each new pair of corners to get that measurement. If you have a patio or driveway you want to harvest water off of, measure the dimensions of that too. Note all these down on your aerial photo. To get rid of the green lines, hit "CLEAR" on the menu bar (its on the right part of the upper menu) at any time.

8. If you want to get areas of your roof or yard, use TOOL/MEASURE TOOLS/MEASURE POLYGONS. This time, click on each corner of the area you want to measure until you get to the last corner, then double click. You will see a green shade form over that area. Put your arrow over the area and the square footage will appear on the screen. 9. There are other interesting layers on the mapping website that you might want to check out. To do this, go back to MAP/TABLE OF CONTENTS/STORMWATER. You can click on any layers you want. An especially good one is the "contours, 1988." This one doesn't work for my Mac, but might work on your computer. If you can get the contour lines, that is great. Print this one. Other good ones are "RIPARIAN AREAS" and "WASH." Print these too if you have a wash running through your property.
