Good Design is the Best Guarantee of Quality Water

Averaging 350 hours of research and development annually, the company has developed considerable expertise in designing systems that are cost effective, produce high quality water, and are easy to maintain. We continue to monitor our projects and consequently maintenance is the cornerstone of our design. This experience and on-going re-evaluation has helped us improve initial design and construction techniques and has led to the development of locally manufactured components specifically for southern British Columbia rainwater collection systems.

We work closely with our clients to ensure sensitive design and bring an experienced and creative approach to developing practical and cost effective solutions that will accommodate long term needs.

Our design balances five sometimes-competing concerns:

  • The unique requirements of the client and the site
  • System efficiency (collecting the highest proportion of the available rain)
  • Water quality (collecting clean safe water)
  • Aesthetics (most of the components can be hidden if desired)
  • Straightforward but effective cleaning and maintenance

Typical Steps in the Roof-to-tap Design Process:

  1. Calculating Storage Requirements
    Use a computer water balance table that combines:
    • the roof catchment area,
    • the anticipated catchment efficiency,
    • the local rainfall statistics for the area, and
    • the estimated monthly household water use
    Based on these factors the water balance table calculates the amount of water in a given size of cistern at the end of each month. When the need for certainty and the extra water requirements for fire suppression are added in, the client is able to determine a cistern size that they feel "comfortable" with. The cisterns is often smaller than the client originally believed was necessary.
  2. Decide on storage cistern type and location
  3. Develop a Rainwater Concept plan showing how to run the water from the roof to the cistern, and clean it on the way
  4. Develop the Water Distribution Plan showing how to pressurize the water to the taps. This includes the type and location of water disinfection equipment if the water is to be used for indoor potable uses such as drinking.
