Rain Today, Water Tomorrow: Why Rainwater Harvesting Matters in Bastrop & Lee Counties
Texas is no stranger to dry spells, but in recent years those dry months have become longer, and more frequent. Historically, December through February are among the driest months of the year across much of the state. As a result, Texas often enters spring with limited soil moisture and very little groundwater recharge. When these already-dry months are followed by longer gaps between rain events, water demand increases while natural recharge slows, placing added pressure on our groundwater aquifers. As rainfall becomes more unpredictable, capturing and using water wisely during wetter periods can help communities better prepare for extended dry stretches ahead.
This challenge is especially important in Bastrop and Lee Counties, where residents rely 100 percent on groundwater for their water supply. Every gallon used comes from the aquifers beneath our feet, and during drought conditions, increased outdoor watering and household use can significantly raise groundwater pumping. Higher demand today can mean less available water in the future.
One practical way residents can help reduce demand on our aquifers is through rainwater harvesting. Rainwater harvesting allows homeowners to capture and store rainfall from rooftops for later use, such as watering lawns, gardens, and landscapes. Some homeowners even install a filtering system to use their rainwater for the house. Using harvested rainwater during dry months reduces the need to pump groundwater at times when aquifers are already under stress. It also provides a valuable backup water source during drought conditions, helping homeowners maintain their properties while being mindful of long-term water availability.
The impact of rainwater harvesting adds up. In 2025, the Lost Pines Groundwater Conservation District approved 43,582 gallons of rainwater storage capacity through its Rainwater Harvesting Rebate Program. That stored water represents a meaningful reduction in groundwater demand and supports sustainable water use across the District.
The Rainwater Harvesting Rebate Program is continuing into the new year and is available on a first-come, first-served basis. The program helps offset the cost of installing an approved rainwater harvesting system for properties located within the District. Requirements include attending a Rainwater Harvesting 101 Workshop, submitting an application prior to installation, and completing an inspection once the system is installed and operational.
To help residents get started, Lost Pines GCD is hosting a Rainwater Harvesting 101 Workshop in collaboration with the Aqua Water Supply Corporation and Bastrop County Master Gardeners. The workshop will be held at Aqua Water Supply Corporation’s Annex building on Saturday, February 28 from 10:00 AM to 12:00 PM. Participants will learn the basics of rainwater harvesting, system components, best practices, information on native plants that use less water, and how to apply for the rebate program. Space is limited. To register, please call (512) 360-5088.
By capturing rain when it falls, we can reduce pressure on groundwater during drought, stretch local water supplies further, and build resilience in the face of Texas’ increasingly unpredictable weather. Rain today truly can mean water tomorrow.
