Save Water and Collect Rainwater!

A Great Idea

As society becomes more aware that our natural resources are being depleted faster than they can renew themselves, we have come up with more ways to conserve and protect them. Have you ever considered collecting rainwater and putting it to good use? Think about every private and public property in the city. Now think about how much water each of those properties use. That’s a lot of water, isn’t it? Now try to imagine every single one of those properties collecting rainwater and using it for some of their water needs. Imagine how much of our municipal water source would be conserved. I know that it’s a stretch to think about every single property in the city collecting rainwater, but I think it’s possible for a rainwater harvesting movement to start with more homeowners in the city.

An Inside Look to Round Rock’s Water Usage

As our city grows, our water use does too. Have you ever wondered how much water is withdrawn from our water source (Lake Georgetown) in one day? According to the City of Round Rock Water Production Report, in August (one of the hottest summer months) produced a daily average of 28.1 million gallons of water.  Lake Georgetown supplies water to Georgetown, Round Rock, and Brushy Creek MUD. Think about those three cities water use in one day all together…

Some might ask, “Why would I collect rainwater and what would I use it for?”

Ways to use collected rainwater

  • Water landscape (via hand watering or hooking up to irrigation system)
  • Water gardens
  • Water indoor plants
  • Washing cars
  • Household cleaning

Some more complex uses

  • Refilling pools, fountains, or bird baths
  • Washing clothes (if connected)
  • Flushing toilets (if connected)

Benefits of rainwater harvesting

The benefits of collecting rainwater are countless, but here are just a few to get you thinking about how it could directly affect you.

  • Non-chlorinated water is better for plants and landscapes
  • Reduces erosion on properties
  • Reduces rainwater runoff that would be contaminated
  • It can be used as a backup water source for emergencies
  • Reduces demand on municipal water sources
  • Reduced water bills because rainwater is FREE
  • It uses simple technologies
  • Easy to install
  • There’s a rebate from the City!  https://www.roundrocktexas.gov/rebates/

Something to think about

Here in Texas the weather can be a little strange to say the least. One month we could have large amounts of rain and the next could be completely dry. Just think about this past spring of 2019. It rained a total of 17.4 inches, averaging about 4 inches a month. (March-June) Then in July it felt like it just stopped raining and we started heading towards drought conditions. During the hot and dry summer months (July-September) it rained a total of 1.56 inches of rain.

Half of Williamson County is in severe drought as I’m writing this. We aren’t under any water restrictions, but it’s scary to think about the water usage and replenishing ratio. As it gets hotter and dryer here in central Texas, a lot of homeowners start watering their lawns and plants more. I mean nobody wants their lawns and plants to die! Thankfully, this fall has brought down some temperatures and brought us some rain.

Picture this

This is an example of how much water a common house would use for irrigation. In this scenario, I will be using the average lawn size for a home in Texas.

Front and backyard lawn total- 7,552 sq. ft

A lawn needs about 1 inch of water (0.623 gallons) per square foot during summer months.

So that means I must multiply the 1 inch of water (0.623 gallons) by the amount of square feet there are in that lawn.  7,552 X 0.623= 4,705 gallons

If I water twice a week, that’s 9,410 gallons per week!

Now think about some of those huge commercial properties that have a lot of land to water.

Each number is in thousands of gallons. Click here for more information

How much water can be collected?

Some might ask, “will I even be able to collect enough water for actual usage?” or “would this really make an impact?”.  According to the Texas Water Development Board, for every inch of rainfall that falls on a 2,000 square foot roof, the rainfall collection yields to about 1,000 gallons.

Here’s an example of how much water you could collect during a rainy spring to use during a dry and hot summer.

Rainfall amounts from (March-June 2019) reached 17.40 inches in Central Texas.
According to the US Census, the average home in the US South is 2,392 square feet.

You will get 0.623 gallons (1 inch of water) for one square foot of your roof

2,392 X 0.632= 1,490 

1,490 X 17.4= 25,926 gallons

25,926 gallons of water collected during spring. If you wanted, you could use all that rainwater instead of your irrigation for a whole month! It would be especially helpful if the city were to go on mandatory water restrictions during a drought.

Collecting Rainwater can be simple!

Whether you are going to DYI or buy a container for storing rain, there are three basic components of a rainwater harvesting system.

  1. Catchment area- roof (impervious cover) that catches rain.
  2. Conveyance system- transporting rainwater from catchment area to storage (gutters and downspout)  
  3. Storage- container for storing rainwater. You can attach a rain barrel to your home’s downspout.

There are great guides to installing rainwater harvesting systems

The Texas Manual on Rainwater Harvesting from the Texas Water Development Board to learn how to install your own rainwater harvesting system.

Collecting rainwater is a great way to help save the most precious natural resource, water. It also will help YOU save money! The benefits are endless, and you will be doing your part to help protect Earth.

 

 

 

Celebrate and Save Water this Weekend

This holiday weekend, you can double-dip on savings on products to help you reduce your water use at your home or business.  This is the second annual Lawn and Garden Water Smart Tax Holiday!

This Memorial Day Weekend, May 27-29, 2017, consumers can purchase water saving items without paying sales tax.  Water saving items, as defined by the Texas Comptroller, can include any plant product, any product with a WaterSense label, mulch, rain water collection systems, and much more!  There is no limit to how many items you can purchase.

This holiday was established in 2016 to encourage Texans to be Water Smart!  Texas comptroller Glenn Hegar said, “Ensuring Texans have an adequate supply of water is fundamental if we want to continue creating jobs and growing the economy,” he continued. “The Tax Holiday helps Texas consumers be water smart, saving money and water in their outdoor landscapes.”

The categories of products is pretty broad; you can buy items tax free during the holiday that are used or planted for:

  • conserving or retaining groundwater;
  • recharging water tables; or
  • decreasing ambient air temperature, and so limiting water evaporation.

Examples of items that qualify for the exemption include:

  • a soaker or drip-irrigation hose
  • a moisture control for a sprinkler or irrigation system
  • mulch
  • a rain barrel or an alternative rain and moisture collection system
  • a permeable ground cover surface that allows water to reach underground basins, aquifers or water collection points
  • plants, trees and grasses
  • water-saving surfactants
  • soil and compost

If you’d like more information on the products and plants you can purchase tax-free this weekend, visit landscapetexas.org or the Texas Comptroller’s website.

Remember, the City’s Water Conservation program offers rebates on many water-saving and WaterSense labeled items.  And residents can always pick up free mulch from the brush recycling center.

 

We Want to Alert You!

Is there truly ever a time that we enjoy opening bills?  I can’t think of any, except when maybe I’ve just paid off a credit card and am very happy to see the zero balance!  Who wouldn’t enjoy knowing you owe no money that month!?!?  I would love it!high bill

Well, when the opposite happens–opening a bill you thought would be small, but was very high—that can cause a lot of unhappy feelings, stress, anger, confusion—what happened?  Why is this so high?  Why didn’t I know?  Enter applicable emoji faces here.  Ha!

The City is trying to prevent that negative reaction from happening when you open up your water bill each month.  Thanks to the new automated water meters that the Utility Department has installed over the last several years, we can now let you know if you’ve had water running through your water meter without stopping for over 24 hours!  Pretty cool!

Here’s a little history on these new meters:  Back in 2009, we began upgrading the meters from a traditional meter that is read each month (and only once per month) by actual persons that walk the town, street by street, opening up meter boxes to write down that month’s number.  That was pretty inefficient, but the standard practice in the water metering world.  Those new meters installed starting in 2009 were called AMR (automatic meter reading), as a person didn’t have to walk all day and open up these boxes.  Now we could read the meters from the comfort of a car, with this drive-by system, as the meter reads would automatically be uploaded into the computer in the car with the now-mobile meter reader.  This allowed the city to read meters much faster, find meters that weren’t working quicker, prevent mistakes made when manually reading the meter, and provide more water data and information to you (our water customers) about when water is being used at your property.  (You may have seen some of the cool water use graphs we can now access.)

Moving forward, starting in 2015, we upgraded the meters again, moving to an even more automated system where now we don’t even need to drive-by to get the monthly meter reads.  Now, the meters send their reads twice a day to our billing software infrastructure.  This makes us even more efficient in removing vehicles off the road (helping with air quality, saving fuel costs), knowing nearly immediately when meters stop working, having quicker access to water use to help answer questions about why bills may be high, and again, (we’re coming full circle now) let you know if you have a leak registering on your water meter.

We receive an alert from the meter if water has been flowing for more than 24-hours without stopping.  So, rather than finding out a month or so later (when the bill comes in the mail AND you’ve actually opened it), you now may find out within a week that you have some kind of odd water use.  You can start checking things out at your house to prevent that shocked when opening the bill experience!  Maybe it’s an easy-to-prevent toilet leak, a water hose left running, a swimming pool fill stuck open, or unfortunately something worse, but we want you to know about it as soon as possible to prevent damage, save money, and save water! alert word

The leak alerts will primarily be sent in the mail as a postcard, but may be a doorhanger, or an email.  We aren’t able to say what specifically is causing the constant water use, we can only tell you that water is being used continuously at your house.  Hopefully before the end of this year, you’ll also be able to receive this alert as a text message.  More on that coming soon!

Starting this leak alert notification is just another way we are striving to save water as a community and provide the best customer service we can, to you!  I really hope you never get one sent to you—no one wants a leak!  But if you do, you’re welcome!
