Rainwater Catchment System Design
We begin with an initial consultation and on-site assessment to determine optimal placement of the water tank and system components such as filtration and pump elements. We then estimate the amount of water that can be collected on the catchment surface (in most cases, the roof). For every 1,000 square feet of roof surface, one inch of rain will produce 625 gallons of stored water. This translates to approximately 40,000 gallons of catchment potential per year, given a typical home size of 2,000 square feet and San Antonio’s annual rainfall average of 32 inches. Once the calculations are done, we size the water catchment system and tank appropriately and proceed to the installation phase.
Greywater System Design
Graywater systems are designed to divert wastewater from sinks, showers, baths, and washing machines and use the water for landscape irrigation (wastewater from food preparation sinks and toilets is considered black water and is not used in greywater systems). On new home construction projects, we work with homeowners along with the architects, builders and plumbers to design a fully customized and efficient greywater system with the ability to divert and recycle 60-80% of residential wastewater. The benefits of a greywater system include reduced use of potable water, less strain on septic systems, reclaiming an otherwise wasted valuable resource, recharging groundwater, and the ability to irrigate landscape and trees in times of drought.
Water Tank Installation
In addition to designing and installing water collection systems, we are also authorized dealers and installers for CorGal water tanks. This makes us a convenient option from the consumer standpoint, since we’re able to take care of all details of the system from start to finish and offer a “turn-key” installation. Most of the tanks we install are 7 feet 3 inches tall, and they vary in volume from 2,500 to 65,000 gallons. We also install the concrete pads required for the tanks, along with the piping and all of the components of the water collection system.
Why Choose a Rainwater Harvesting System?
There are numerous benefits to harvesting rainwater, many of which are specific to each household’s particular situation and needs. Following are some of the more universal reasons why our clients choose to have a rainwater harvesting system installed in their homes.
