Rainwater Harvesting

Rainwater Storage & Management Systems

Serving Lexington & Central Kentucky

H2O Designs organic approach to water gardening is based on recreating a naturally functioning environment. Water circulation, filtration, Pond fishaquatic plants, rocks and gravel all used to ensure a balanced ecosystem and long term sustainability. H2O Designs Inc. is committed to further expanding its environmental position by implementing innovative new products with a focus on the environment and the long term sustainability of our most precious resource here in the Lexington / Central Kentucky (Ky) area, water.

The Aquascape Inc RainXchange™ (Rainwater Harvesting) System offers both residential and commercial consumers the opportunity to do their part to address some of the challenges associated with drought and the increasing problem of excessive rainwater run-off common in our local municipalities. We have highlighted just some of the benefits of this exciting new system below.

Do I Leave My Waterfalls Running or Pull the Pump?

Winter Pond Maintenance is usually the determining factor in whether or not Central Kentucky pond owners keep their pump running in the winter. The primary maintenance responsibility at this time is to make sure there is enough water for the pump(s) to operate properly all winter long. A  Pond pump that provides at least 2,000 gph can be operated throughout the winter here in Central Kentucky without a problem, as long as it runs continuously. The moving water will usually keep a hole open in the ice around the waterfalls and in front of the skimmer.

There is nothing more breathtaking than a waterfall covered with ice formations and snow during the winter. You must, however, be careful with ponds that have long or slow-moving streams. In such cases, ice dams can form and divert water over the liner.

Utilizing rainwater for garden and lawns reduces the strain on municipal systems. What’s more, the stored rainwater can alleviate water shortages during periods of drought. The rainwater harvest storage system helps alleviate flooding that typically occurs when heavy rains follow a drought, Aquascape’s RainBank Systems are designed to supplement Aquascape’s Pondless Waterfall, or decorative fountainscapes products.

With H2O Designs Rain Bank Calculator we solve how much rain you can save in any given month or even the entire year. Did you you know that the average 2000 sq ft home can collect over 60,000 gallons a year. This water can now be harvested and recycled for numerous uses such as watering gardens, irrigation for greener grass and even potable water.

Why Rainwater Harvesting?

State of the Environment
Water is quickly becoming an “endangered species” on our blue planet.  Urban growth increases storm water runoff, which in turn harms natural waterways.  All life requires water for survival.  Becoming aware of the current state of our environmental condition is the first step in identifying viable solutions to ensure clean and healthy water for future generations. 
  • Local water sources such as lakes, reservoirs and groundwater continue to decline despite regular rain events.
  • Demand is becoming greater than the supply and the rains that do fall on our ground are lost.
  • Rainwater is actually flowing away from the area it falls on due to development.
  • Water cannot soak into asphalt, concrete or shingles. It flows very quickly off of these surfaces and in the process it carries a variety of pollutants from dust and dirt to oils, fertilizers and pesticides.
  • This mixture flows quickly into storm sewers and in some cases, ponds and streams.
  • Highly developed areas can have 50% or more surface area covered by impervious surfaces forcing water away from the area where it’s needed.
  • Increased water velocity strips the aquatic vegetation from the shores exposing the soil to subsequent erosion and habitat loss.
  • According to the EPA, urban runoff is the number one cause of pollution in coastal environments.
    • Almost 50% of our stream miles, 45% of lake acres and 35% of estuary and baysquare miles surveyed by the EPA are considered below the standards for fishing and swimming.
  • As rainwater run-off is carried away it does not have the opportunity to soak into the soil or groundwater reserves so our aquifers continue to lose water and new water is not coming in.
  • Wells throughout the country are going dry or have to be lowered to access the lower water levels.

Rainwater Data

  • One inch of rainfall on a 2,000 square foot residential roof generates 1,250 gallons of water that can be reused.
  • That same roof in a region receiving 30 inches of annual rainfall generates 41,000 gallons of reusable water.
  • The average U.S. household with a 10,000 square foot lot uses up to 3,000 gallons of water weekly for landscape irrigation.
  • Running a sprinkler for 2 hours can use up to 500 gallons of water.
  • Seventy percent of water used at home is used outdoors.
  • 66,175 gallons of water are used outdoors per household, per year.

Benefits of Reusing Rainwater

Why let good water go to waste when you can reuse it for another purpose? The benefits of harvesting rainwater are numerous, but some of the more prominent advantages include:

  • Reduce water bills including city storm sewer charges
  • Alleviate demand on municipal systems
  • Avoid strict watering schedules
  • Improved landscape growth
  • Reduce flooding and erosion
  • Efficient use of a valuable resource – water

Aesthetic Benefits

The RainXchange™ adds the beauty of a water feature to an efficient system for capturing, filtering, and reusing our most precious resource – water! Whether you choose a Pondless® Waterfall or bubbling urn to your landscape, you’ll be happy knowing your RainXchange™ System not only looks great, but is beneficial for the environment, too.

Wildlife Habitat

Because the water stored in the RainXchange™ System is constantly moving and being aerated, it becomes a sanctuary for wildlife. Birds, frogs, dragonflies and butterflies all flock to water in the landscape.  In fact, water is a key component in certified wildlife habitats.


Capturing rainwater to operate a decorative water feature creates true self-sustainability, drastically reducing the need for chemically-treated traditional water sources. 

Ease of Use

While you enjoy the benefits of a decorative water feature, the RainXchange™ System filters the stored water to prevent stagnation and growth of unhealthy bacteria. Accessing the stored underground water is easy as connecting a hose to a spigot.  A small pump is connected to the stored water making it convenient for you to water the landscape.
