In response to ongoing drought conditions, conservation groups in Central Texas are advocating for rainwater harvesting as a sustainable water source. RainBees, a local organization, offers free consulting services to help businesses, builders, and homeowners design and install these systems.
Understanding Rainwater Systems
Rainwater collection systems are categorized into two types: dry and wet. A dry system places tanks close to a structure, allowing rainwater to flow directly into them. In contrast, a wet system involves placing tanks further away, with underground pipes that retain water even after rainfall has ceased. These systems include a low-point cleanout to prevent pipe damage during freezing temperatures, as explained by RainBees consultant Larry Sunn.
Groundwater Crisis
Despite recent rainfall keeping lakes Buchanan and Travis at normal levels, groundwater remains in a dire state. Lane Cockrell, general manager of the Southwestern Travis County Groundwater Conservation District (STCGCD), highlights the challenges posed by the Lower Trinity Aquifer’s slow recharge rate. Some areas may not see replenishment for thousands of years, underscoring the need for alternative water sources, according to Charlie Flatten, general manager of the Barton Springs-Edwards Aquifer Conservation District (BSEACD).
Severe Drought Conditions
Both the STCGCD and BSEACD have declared extreme drought conditions as of May 15. The Hays Trinity Groundwater Conservation District is in an emergency drought stage, predicting a need for 37 inches of rain over the next six months, a scenario with less than a 1% probability of occurring.
Practical Solutions for Families
RainBees provides practical guidance for families looking to implement rainwater harvesting. For instance, a 2,400-square-foot roof can collect approximately 1,488 gallons of water per inch of rainfall. Families are advised to maintain a three-month water supply to manage periods of reduced rainfall. For a family of four, this equates to about 18,000 gallons.
