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.

Reduce your water bill

With continually rising municipal water rates, a rainwater harvesting system can put you in control of your water expenditures and pay off to save money over the long term. A 2,000 square foot home typically collects 40,000 gallons of rainwater every year, given the Texas rainfall average of 32 inches.
 

Conserve water

Approximately 50-70% of an average household’s water supply is used for landscape irrigation. According to the EPA, a typical landscaped yard soaks up more than 10,000 gallons of water per year, not including rainwater and snowmelt.
 

Superior landscape irrigation

What makes rainwater better for irrigation is not just the harmful chemicals and treatments it doesn’t have, but also what it has above tap water in the way of vital nutrients. Rainwater is naturally high in nitrogen necessary for plant growth while tap water contains salts, chlorine, fluoride and other chemical treatments that are harmful to plants.

No need for water softeners

Rainwater doesn’t contain harmful minerals and salts that are known to affect our local hard water supply. Pipes, water heaters and faucets will last longer without the wear associated with hard water deposits.
 

Easily purified for potable use

Tap water often contains a number of contaminants, including known and suspected carcinogens as well as substances toxic to the endocrine and nervous systems. Bottled water is wasteful, expensive and oftentimes nothing more than filtered tap water. In contrast, rainwater is free of many of the harmful chemicals that are found in tap water (including chlorine, fluoride, chloroform, and pesticide runoff) and is easily purified for a safe, abundant supply of drinking water.
 

Delicious and pure

Purified rainwater is one of the highest-quality, best-tasting sources of drinking water available.
