Appropriate size, functional, meets the intended needs

Rainfall Characteristics

Rainfall intensity and totals, drought seasons, and  air pollution are but just a few of the items that determine how much water you can collect, at what times of the year.    Read more.

Collection Surfaces

Any surface that rainfall is collected from impacts the quality of that water.  We want to avoid chemicals  and contaminants.  If the surface is toxic so will be your water, if the surface is dirty so will be your water.   Read more to Learn of good and poor surfaces

Conveyance and pre-filtration

Getting the water from the collection surface to the storage system.  On this journey the water needs simple pre-filtration to remove coarse debris and fine contaminants.   Read more to learn about components that make up this stage of a rainwater system.


Deep topic and many choices.  This is one of the biggest and most expensive decisions in any rain water harvesting system, one that takes lots of design time.   The rainfall patterns and usage patterns will determine storage needs.    Read more to learn about the options.

Pumping & Pressurization

Depending on the end use, and where your storage system is located gravity may be sufficient to meet your needs, or pumping to attain higher pressure and flow rates, or perhaps water just needs to be transferred to a higher storage location to rely on gravity.  Read more on the options around pumping and pressurization.  


In virtually all applications some level of filtration is required.  Not all applications need the same level, and contrary to popular belief not all potable water systems require UV or chemical treatments.  Read more to find out about filtration options.


Just because rain falls from the sky does not mean it is safe.  And if the rain is clear and clean, not all ways of storing it are safe.    In each stage of collection, storage, pumping and filtration safety considerations must be closely adhered to.  Read more about safety and your water.
