KEARNEY STORMWATER MANAGEMENT
MCM #3 Illicit Discharge Detection and Elimination
Capetown’s crisis is in the spotlight now, but other metropolitan areas could soon follow:
KEARNEY STORMWATER MANAGEMENT PLAN
Cloudy winter days make the snow melt faster, says a study from the University of Utah. Snow is designed to stay cold in three ways: by deflecting the sun’s heat with it’s bright white color and crystalline structure, the bright white reflecting heat back at night, and sublimation, evaporating from snow to vapor, similar to the way sweat evaporates from our skin to keep us cool.
Cloudy humid days, however prevents snow from deflecting, reflecting and sublimating warming the snow. That is why a few humid days with temperatures hovering around the freezing point create large melt events and even minor flooding.
Do your own experiment by watching snow that remains in shadows even on warm sunny days. Then watch what happens to that same snow during gray days and nights — quickly, though, before it’s all gone.
“I cannot stress it enough: all residents must save water and use less than 87 litres (23 gallons) per day.” – Patricia de Lille, Mayor, Capetown, South Africa
Three consecutive years of drought have brought Capetown, South Africa to the end of it’s water supply. All taps serving the city’s 3.74 million residents will be shut off April 21 – “Day Zero” – when the water is gone. Should the taps be turned off, each resident will be allocated 6.5 gallons of drinking water per day shipped from neighboring provinces.
The average U.S. resident uses 100 gallons per day – 4 times the current recommended use for Capetonians. How much more could we conserve?

Here are 10 top ways to save water in the New Year.
1. KNOW WHERE YOUR WATER IS WASTED
Scottsbluff pumps 6.6 million gallons a day in the heat of the summer and 2.8 million gallons a day the coldest month. The majority of the difference is for lawn irrigation. Limit outdoor w
ater waste with drought tolerant turf, xeriscaping, rain gardens and other sustainable landscape options.
2. UPGRADE YOUR APPLIANCES & FIXTURES
Choose a WaterSense labeled high-efficiency clothes washers, toilets, and showerheads to save more than 20% from conventional appliances.
3. WATER LESS
Water at dawn while cool and calm, to reduce evaporation. Water in short bursts, instead of a long soak, for better soil infiltration.
4. SHORTEN YOUR SHOWERS
Even a one- or two-minute reduction can save up to 700 gallons per month, for a family of four. Save up to 200 to 300 gallons per month by using a bucket or to capture what is waste while waiting for the shower or sink water to warm up, and use it on house-plants or in your garden.
5. SWEEP, DON’T HOSE
Save 150 gallons or more by sweeping instead of hosing driveways and sidewalks. Don’t run the hose while washing your car on the lawn. Instead, use a bucket of water and a quick hose rinse which saves 150 gallons each time and gives the lawn a water boost.
6. WATER THE GREEN, NOT THE GUTTER
Adjust sprinklers so that water lands on the lawn or garden – and only there. That can save 500 gallons per month. Check for broken or clogged sprinkler heads. Also, ensure that drip system nozzles and emitters are directed toward your plants and not at a sidewalk or driveway.
7. PLANT A NATIVE GARDEN
Native gardens require less maintenance, don’t need chemical fertilizers and attract butterflies and hummingbirds! Panhandle friendly plants can reduce a home’s water consumption by 60 percent.
8. DON’T WASTE THE RAIN
Capture rain runoff in a rain barrel to water the garden or design a swale to slow, spread, and sink rainwater into the soil. That way you’ll need to irrigate less and can conserve more.
9. DON’T WATER WHEN IT RAINS
It seems obvious, but don’t water during downpours or in the hours after a storm. Rain or soil moisture sensors can determine if and how long to water. Both devices can stand-alone or added on to existing controllers. They can reduce outdoor water use by up to 70 percent without sacrificing the quality or health of your landscape.
10. LOCATE THE LEAKS
A minor leak can waste 20 gallons a day and a leaky toilet wastes up to 200 gallons of water per day. Don’t let minor water leaks in your home go unfixed. Check for and repair leaks in all toilets, faucets and showerheads.
Researchers, led by Estelle Chaussard from the University of Buffalo, link ground water recovery in Santa Clara Valley California to the state’s newly instated water conservation efforts—policies that diverted surface water to refill aquifers
In 2013, interferometric synthetic aperture radar (InSARa) measured a 2-centimeter decrease in ground-level elevation, followed by another 3 centimeters in 2014. The research team estimates a groundwater loss of about a tenth of a cubic kilometer caused the ground to shrink or lower.
Ground surfaces began to expand and rise in September 2015, rising nearly 2 centimeters over the next two years and were at pre-study levels by the end of 2016. This reflects the same time surface water diversion policy went into effect.
Falling leaves signal the official arrival of Autumn. Put leaves to good use as insulating mulch in a garden bed, make them into compost, or shred them across the lawn as a natural fertilizer. Left to lie in gutters, leaves quickly clog storm drains leading to flooding in a Fall storm and nutrient pollution as the leaves degrade in the storm sewer. Pile ’em up and enjoy the benefits of leaves next spring!
