2010 Summer Watering Rules and Tips
Denver Water’s 2010 Summer Water Use program in effective May 1 to October 1.
As spring flower begin to bloom. It’s important to remember that we live in a semi-arid climate and must always use water wisely. Enclosed are watering rules, times, tips and tools to help you use only what you need and make wise water use a normal way of life.
Watering Rules
In 2010 Denver Water will continue to enforce watering rules, so please use water wisely.
· Water during cooler times of day — lawn watering is NOT allowed between
AM to 6:00 PM.
· Do not allow water to pool in gutters, streets and alleys
· Do not waste water by letting it spray on concrete and asphalt
· Repair leaking sprinkler systems within 10 days
· Do not use spray irrigation during rain or strong winds
*Please note, there are some exceptions to watering rules and how the rules apply to gardening.
THE MORE YOU USE, THE MORE YOU PAY
Water rates increased for 2010. Follow these rules and guidelines and you’ll reduce waste and save money. For more information on rates, visit our rates section.
Watering Days and Times
Recommended watering times change as summer weather heats up and cools down, so refer to the chart. Watering two days a week should be sufficient during most of the summer. If needed, water a third day during extreme heat or dry periods. Water trees and shrubs as needed, but not between
Use the chart to help determine the number of minutes to water each zone on the days you water. Get to know your timer. Never set it and forget it. These times are averages. Adjust your watering minutes based on rainfall, type of grass or plants, sunny or shady locations and other characteristics of your yard. If your lawn looks healthy, try reducing these times by two minutes per zone.
Remember, no watering between

Watering Tips and Tools
Here are some simple tips for outdoor watering to help you use only what you need.
Your lawn may not be as thirsty as you think. Tip: Walk across your lawn. Look back for footprints. If you don’t see any, your lawn doesn’t need water.
2. Change the time setting on your automatic controller each month.
Once a month, adjust the clock on your irrigation system to the correct watering times (see chart). As you get to know your landscape needs, try shaving two minutes off a few zones and save even more water. You can maintain a healthy lawn with less water, and adjusting the watering times based on seasonal weather conditions helps you use only what you need.
3. Cycle water: 5 minutes on, 5 minutes off.
Regulate your water usage with an inexpensive, easy-to-use hose timer. Install the timer between the spigot and the hose. Some timers allow cyclical watering — 5 minutes on, 5 minutes off — so that water penetrates the soil, creating a healthier lawn with less water. For clay soils and slopes, eliminate runoff by applying water for a short time, such as 5 minutes, allowing water to soak in. Repeat this cycle until soil is saturated, never longer than 30 minutes.
4. Don’t water during rain or strong winds.
If you have an automatic sprinkler system, consider installing a rainfall sensor to prevent your system from watering in the rain. Denver Water offers rebates worth $25 to $50 for these devices. Wind is an enemy of spray irrigation. It speeds evaporation, and water blows away from intended landscapes. Wait for winds to die down.
5. Add a weather-based smart controller to your irrigation system — especially if you have a large lot.
Evapotranspiration (ET) is a measure of water lost from soil by evaporation and transpiration (usage by plants). A weather-based smart controller, or ET controller, can be added to your system so watering is based on ET readings. By taking into account air temperature, relative humidity, solar radiation, wind and natural rainfall, an ET controller calculates the degree of evapotranspiration and allocates the proper amount of water for your lawn.Denver Water offers a rebate of 25% off the purchase price for such devices. Contact your irrigation or landscape service provider to help with purchase and installation.
Remember, no watering between

Save Our Shade - Trees Need a Drink in the Winter
Denver Water wants its customers to remember their trees this winter. It is not time to water your lawn, but your trees could use a drink. Prolonged dry periods and high winds can dry trees and top soil, and watering your trees will help ensure their optimum health.
Denver Water has some tips to keep trees healthy during winter dry spells:
• Apply water to the root area one to two times a month.
• Water slowly, applying water as wide as the tree’s canopy or branches.
• Water efficiently, using a deep-root fork needle, soaker hose, soft spray wand.
• If you use a hand-held hose, don’t leave it hose unattended, as water runoff can occur.
• Apply mulch a depth of three inches around the base of the trunk to help retain soil moisture during winter months.
• Water only when the temperature is above 40 degrees and there is no snow on the ground.
• Stressed trees are more vulnerable to disease and insect infestations. Make sure to watch trees for any unhealthy signs and consult a professional for remediation options.
• A healthy tree needs 10 gallons of water for every inch diameter of the trunk.
The care of trees this winter will save our shade for the future. For more specifics on tree watering, visit the conservation page at www.denverwater.org.
SEWER GUIDELINES
PLEASE BE AWARE that our sanitary sewer system is designed to handle ONLY three types of waste products:
WE ARE ASKING THAT RESIDENTS DO NOT USE THEIR TOILETS AS TRASH CANS. Flushing foreign materials puts yourself, your neighbors, and your community at risk for costly sewer line repairs and reduces the service life of the main lines and pumping equipment, and increases the cost of maintaining the District’s sewer system.
Any item that is flushed down the toilet, or poured down a sink or drain, has the potential to accumulate in the District’s sewer main causing a hefty backup. Or, objects may become lodged in the rotating impellers in the pumps used to move our wastewater to the City of
Diapers, feminine products, grease buildup, and tree roots are the leading causes of preventable backups, but everyday items such as dental floss, newspaper bags, sanitary items, adult/baby diapers, pine cones, Q-tips, band-aids, gauze, string, chains, goldfish, jewelry, keys, rocks, toys, dish towels, pantyhose, coins, garden hose, wads of hair, gum and other foreign objects have been found flowing through our sanitary sewer system.
Sinks and floor drains are also not meant for the disposal of grease, oil, sand, coffee grounds, paint, flammable liquids, kitty litter, bird seed, wax, or raw or cooked food of any kind.
NEVER flush prescription or over-the-counter medications or hypodermic needles. Hazardous materials and toxic or caustic liquids must be disposed of according to city and county regulations.
SUMP PUMPS.
No SUMP PUMP shall be connected or discharged into the District’s sanitary sewer system. The District may require inspection of all SUMP PUMPS to insure proper installation and daylighting.
Bathrooms
You can do a complete bathroom check in fifteen minutes once you gather up a few necessary tools. You will need a bottle of food coloring and either a "flow bag" (available from Denver Water) or a utility bucket with known capacity. Start your audit at the toilet.
Check the toilet.
Check the sink.
Check the bathtub/shower.
To finish the bathroom audit, look at the toilet again. If water in the bowl is colored or streaked, then the food coloring has disclosed a leaking flapper valve. Flapper valves are available at any hardware store, and are easy to install. Be sure the one you purchase is the correct one for your toilet. An incorrect one will leak even more!
Kitchen
Check all water sources for leaks, following the instructions above.
Laundry
Check all water sources for leaks.
If you have additional water sources in your house, make sure to thoroughly check these too using the same procedures.
Finding the leaks is only the first step, of course. Fix all the leaks as soon as you can.
Sprinkler System Check List
The checklist will help you to create a better sprinkler schedule by understanding all the areas of your yard. Start with your clock and write down the number of minutes you have per zone. If your clock has more than one program, be sure to fill out a separate sheet for each program. Each program has separate start times and usually more than one. Write down all this information at the top of the sheet.
Inventory Your Sprinkler System
Inventory your sprinkler system by turning on one zone at a time, and collect the information requested on a sheet. Continue this process until you have completed all the zones on the clock. This information can be used to develop a schedule for your clock. Once a week after mowing, go back through all the zones to make sure everything is functioning properly. You can use this information that you have collected to develop a schedule on the Internet. Use the run time scheduler that Denver Water developed.
Watering a Slope
The information you have collected will allow you to develop the most efficient water schedule possible. If you have a zone of turf that is on a slope, then you would want to apply your water in small amounts to prevent runoff. Utilizing the start times on the clock and dividing the amount of water into several start times can achieve this. Our run time scheduler will help you develop the correct schedule.
Improve Maintenance
Dry spots indicate that you might not have proper coverage by your sprinkler head layout. Heads can be adjusted to compensate for the "weak" area. Wet areas could be caused from a leak in the system or low-head drainage. If you notice that you have a leak starting, be sure to fix it quickly to stop water waste and other problems that can result.
