Benefits of Aquamate Rainwater Collection Tanks

Capture water from the tank’s roof​

Rainsaver Gutter System

Aquamate’s rainwater collection tanks can be fitted with our innovative “Rainsaver” gutter system, utilizing the tank’s roof to increase the catchment area for optimal collection of rainwater which is then redirected into the tank. The domed roof on an Aquamate tank has dozens of channels around the perimeter of the roof that run from one side of the cistern to the other. Rainsavers are placed at the end of each channel to collect the water during rainfall events. If the tank is full, the water diverts to the overflow as it normally would.​

What are the important considerations when harvesting rainwater?

No matter what your intended use is, you’ll need a rainwater collection tank to store the rainwater you’ve collected. What you plan on doing with the water after it’s stored will influence your needs. For simple irrigation systems, all you may need is a pre-filter, first flush diverter, and a small pump. For more complex drinking water systems, you may need to consider pumps, pipework, filtration and sterilization systems.

Rainwater harvesting professionals, like those certified by the American Rainwater Catchment Systems Association, are a great way of ensuring that you have the correct parts, your rainwater harvesting system is properly designed, uses good quality products and is installed in a safe and professional manner.

Other rainwater harvesting information

State and county authorities are a great independent resource when it comes to researching the requirements for rainwater harvesting in your area.

In Texas, the Texas Water Development Board (twdb.texas.gov) has published the Texas Manual on Rainwater Harvesting to assist system owners about the products, consideration, and guidelines associated with rainwater collection and re-use.

In California, documents like the City of San Diego Rainwater Harvesting Guide are a great starting point when beginning your rainwater collection and re-use journey.

Is Rainwater Collection legal?

Collecting precipitation from your gutters or tank roof, also known as rainwater harvesting, can be a convenient and economical way to gather and conserve water. But have you ever stopped to ask yourself, Is it legal to collect rainwater? If you live in Texas, you might be surprised by the answer.

The answer is yes. And not only is it legal, but purchasing the equipment for rainwater collection is tax free!

Texas lets people buy rain harvesting equipment free of sales tax, and it’s against the law for homeowners’ associations there to prohibit rainwater collection. A few states in the western U.S. have traditionally outlawed rain harvesting altogether. The reasoning is that rainwater eventually makes its way into streams, rivers, and other water sources to which various individuals possess legal claims. In many cases, those claims go back generations.

Rainwater Harvesting down the ages

Rainwater collection is the process of collecting rainwater through a harvesting or collection system, which can involve barrels, buckets, or other containers to hold the water, such as our large galvanized water tanks. 

Dating back to ancient Rome, the idea of collecting rainwater began when wealthier households were designed with atriums that had shallow pools built into the floor. The pools were meant to collect rainwater to help fill the city’s water supply. Since then, there have been many adaptations on how to harvest rainwater all over the world.
In the United States, rainwater is usually harvested from building roofs and stored in tanks designed for holding all the water. You will usually find rainwater harvesting in states that don’t receive a lot of rainfall annually or that are in a state of drought. Having a rainwater harvesting system in place helps to supplement the water use throughout the dryer seasons of the year.

Collecting and Storing  Rainwater Pays off

Collecting rainwater can help conserve resources and can keep costs down. There are many benefits to consider when catching rainwater.

  • Reduces stormwater runoff
  • Uses simple and inexpensive ways to conserve water
  • Good to use for gardening or watering lawn
  • Less costs on resources
  • Backup source for water emergencies
  • Increase the value of your property with Large Water collection and Storage Tanks
  • Harvesting rainwater has many benefits for homeowners and communities. It’s more eco-friendly and can help the planet.

Before you start collecting rainwater, contact your state government to find out what restrictions, if any, you face. Most likely, you’ll be good to go right away. Once you start using a rainwater collection tank, you’re definitely going to be happy with your investment as rainwater is soft and generally free of salt and toxins, and remains in perfect condition, the way nature intended with our BPA and pesticide Free liner.
