Recent rainfall in the Brazos Valley has put a small dent in the drought conditions. The graphic below shows the rainfall totals on May 13th for 24 hours as shown on KBTX.com website.
Given these rainfall totals, here is how much rainwater you could have captured, for use during the drier months from this rainfall event, if you have a 1500 sq foot surface to capture from:
Bryan/College Station = (1500 x .623) x 3.36 => 3139.92 or 3140 gallons of rain
Caldwell = (1500 x .623) x 3.45 => 3224.025 or 3224 gallons of rain
Cameron = (1500 x .623) x 2.18 => 2037.21 or 2037 gallons of rain
Conroe = (1500 x .623) x 5.49 => 5130.405 or 5130 gallons of rain
Crockett = (1500 x .623) x 2.88 => 2691.36 or 2691 gallons of rain
Hearne = (1500 x .623) x 2.78 => 2597.91 or 2598 gallons of rain
Huntsville = (1500 x .623) x 3.80 => 3551.10 or 3551 gallons of rain
Giddings = (1500 x .623) x 3.34 => 3121.23 or 3121 gallons of rain
Madinsonville = (1500 x .623) x 3.80 => 3551.10 or 3551 gallons of rain
Navasota = (1500 x .623) x 3.36 => 3139.92 or 3140 gallons of rain
Trinity = (1500 x .623) x 2.88 => 2691.36 or 2691 gallons of rain
The real winners were:
Brenham = (1500 x .623) x 14.50 => 13550.25 or 13550 gallons of rain
Hempstead = (1500 x .623) x 14.50 => 13550.25 or 13550 gallons of rain
We aren’t out of the woods yet with summer fast approaching. According to this article on KBTX.com, the ‘rainfall deficit for the year has been cut from around 7 inches to just 3.37″ …’ Easterwood airport officially received 5.44″ of rainfall up to May 14th. This would bring the total above on a 1500 sq ft roof to 5084 gallons of rain that could have been captured.
The Bryan/College Station area generally (using the past 10 years as a guideline) getting around 3 inches or more in the wetter months and with July and August being the driest months at 2″ or less, we hopefully will get another 3-4 inches before the hottest months. So you still have time to get a system in to capture any water that falls to use for your lawn, outdoor plants and/or garden, livestock or pets, and even for potable use.
Rainwater harvesting costs for a system is generally similar to drilling a well with one main advantage. Rainwater is the purest form of water until it hits the ground. So you can have clean water from the start with a harvesting system in place and a few safeguards installed to ensure a trustworthy, clean and sanitary source for water for you and your family.
As always, comments and/or questions are always relevant and welcome.
