Collecting Rainwater in Texas

Rainwater Harvesting Guide

Rainwater collection is a process of collecting, storing, and using rainfall for various uses. The harvested rainwater can be used for a variety of purposes, such as drinking water, irrigation, cleaning, or industrial processes.

Rainwater harvesting is a process of collecting and using stormwater runoff for beneficial purposes. This can be done by strategically positioning gutters, downspouts, and storage containers to intercept rainfall and direct it towards areas with vegetation or to catchment systems that store the water for later use.

What is rainwater harvesting?

Rainwater harvesting offers numerous benefits. It conserves municipal water resources, reduces flooding, and helps protect the environment from pollutants in runoff. Furthermore, collected rainwater can be used for various applications such as toilet flushing, pet and car washing, indoor plant watering, pet and livestock watering, and for lawn and garden irrigation.

There are many types of rainwater harvesting systems available, ranging from simple and inexpensive to complex and costly setups. Generally, these systems involve collecting and storing rainwater in above-ground containers like a barrel or plastic tanks. Doing so minimizes evaporation and keeps pests away from the water. In some cases, such as using direct rainfall to irrigate area plants, no additional equipment may be needed beyond some strategic harvesting setup.

Benefits of Rainwater Harvesting

Rainwater harvesting offers numerous benefits to the environment, people, and businesses. Some of the main advantages include:

  • Reducing Water Waste: Harvesting rainwater reduces the amount of runoff from properties and helps direct the fresh water into more useful channels. This water is perfect for area gardens and landscapes and provides an inexpensive way to meet all outdoor water needs.
  • Saving Money: Rainwater harvesting systems reduce water bills significantly since it allows individuals and companies to become more self-sufficient when it comes to water needs. The upfront cost of installing these systems is typically recouped in a few years due to the drastically reduced costs of using harvested water instead of municipal supplies.
  • Abundance of Water: Rainwater harvesting systems enable users to access an abundance of clean rainwater without relying on running out of municipal supplies or experiencing water restrictions due to droughts.
  • Reduced Stormwater Runoff: By directing rainwater away from streets and other paved surfaces, runoff pollution caused by chemicals and oils are greatly reduced.
  • Improved Soil Health: As harvested rainwater replaces the need for chemical fertilizers, soil health is improved due to increased organic matter and fewer salt deposits.

Is Rainwater Harvesting Legal In Texas?

In the great state of Texas, rainwater collecting is not only legal but encouraged. The State government offers a sales tax exemption on purchases of rainwater harvesting equipment; simply presenting the valid sales docket is enough to qualify.

Homeowners may not be aware of their city or county’s by-laws regarding rainwater collection, as well as assume that a Home Owners’ Association (HOA) can legally prevent them from installing rain harvesting equipment on their property.

It is strongly advised to check with your local governing body before purchasing any equipment.

The use of rainwater harvesting systems has been encouraged by the state of Texas due to its environmental benefits.

In what states is it illegal to collect rainwater?

Rainwater collection is legal in all states across the United States, with Colorado’s ban lifted as recently as 2016. Those living in Colorado should take note of local restrictions when harvesting rainwater. In general, as long as rainwater is collected on privately owned property, citizens can access this valuable natural resource without issue. With more states relaxing laws regarding the use and conservation of rainwater, there are now more opportunities than ever to collect it for personal use and benefit.

States across the United States have restrictions on rainwater harvesting, as this precious resource is often limited. Arkansas allows for the collection of rainwater but requires it to be designed by a licensed engineer and that it abides by all state and county plumbing codes. In Colorado, recent laws lifted the long-standing ban on residential barrels, allowing two with a combined capacity of 110 gallons that must have sealable lids and not be used for drinking purposes. In Illinois, Green Infrastructure for Clean Water Act regulations must be followed, while Oregon applies restrictions to roof surface systems and encourages Portland residents to save the rain through its Clean River Rewards program. Lastly, Utah allows for up to 2,500 gallons of collected rainwater at a time but requires registration with the Division of Water Resources. It’s important to note that these regulations may change over time, so it’s important to stay informed of your local area’s current rules and guidelines.
