Rainwater Harvesting

RainSpace Underground Water Storage Tanks

  • Stored rainwater protects against drought and water usage restrictions, provides water independence and fire protection and avoids shortages from low flow wells. Stored water is available for potable uses, irrigation and fire protection.
  • Water stored underground is higher quality water. It is not subject to contamination from temperature fluctuations and environmental exposure.
  • RainSpace is the lowest cost underground water storage method, unlike rigid tanks and cisterns that are expensive, difficult to handle and costly to install.

Any Capacity – Water When You Need It

  • RainSpace rainwater harvesting storage chambers can be sized to hold any quantity of water.  The capacity is limited only by the space and depth available on the site.

Site Flexible – Difficult or Restricted Sites

  • The Water Storage Tank can take any shape – long and narrow, square or curved. It fits where expensive tanks or cisterns will not work – around trees or structures, on slopes and under driveways or roads..

Strong and Earthquake Proof

  • The chamber can be used beneath driveways and parking areas with cars and trucks.
  • No vertical load bearing components to get misaligned and collapse from earthquakes, soil subsidence or traffic vibration. Water held within the Structural Core Tubes prevents the heavy mass of water from moving and hammering the sides during an earthquake.

Easy Installation

  • Underground Water Storage Tank is a modular system made of lightweight components that are easily handled and quickly installed.  Installation is easy – DIY or quickly done by an excavation or landscape contractor.  Detailed site-specific instructions are provided.

Complete Package

  • RainSpace Rainwater Harvesting Water Storage Tanks are designed for your site and delivered as a complete package ready to be installed in your excavation. The structural core tubes and heavy duty impermeable water containment liner and sealer are delivered with detailed installation guidelines for your site.
  • We work with you from your initial inquiry through the design process and your installation.
  • We make it simple and easy and inexpensive for you to have useful water stored at your home.
