Rainwater Harvesting on Vancouver Island
Jaan Designs offers several options for home owners who wish to incorporate a rainwater harvesting system in their home.
The first step to achieving a successful RWH system is a good design. Rainwater harvesting system design brings together a variety of factors such as, your homes roof area, usage, storage, to list a few. These factors play into the ultimate size and complexity of your rainwater harvesting system. A well designed rainwater harvesting system, ensures your rain water usage will match your storage needs. All of our rainwater harvesting designs allow flexibility to expand your RWH system in the future whether you wish more storage or you have different usage.
Jaan Designs offers Rain water harvesting system design for those who are ‘Hands on’ and wish to install their own system. Using 3D software we can produce drawings which are easy to follow and include supporting documentation, with an option of site visits to help answer any questions during the installation.
This is an exciting option for those wanting to ‘Do it yourself’ but lack the confidence and knowledge to undertake this work.
If you choose to have Jaan Designs install your system, we still provide a 3D design so you can see what the project will look like before we start.

Your rainwater harvesting system integrates the specialized expertise of professionals involved with drainage, plumbing, excavation, construction, electrical, pumps, and water purification. Construction best practices are critical during the installation of your Rain water harvesting system.
A Rainwater Harvesting (RWH) system takes water from your roof and delivers it to your taps. RWH systems remove debris, transport the water to storage for later use, and provides and appropriate level of pressurization and post storage filtration.
Some key components of a rainwater system:
1-Course screen to filter out large debris.
2-First flush device to remove the first .5-1mm of rain off the roof. This contains the highest level of contaminants and is best re-routed into your landscape rather than being stored.
3-Additional gravity filtration if your rainwater is used for indoor non-potable or outdoor drip irrigation. These filters vary in mesh size and often two filters are used, one course and one finer.
4-Level tank or tanks as per your design with all of your fittings planned out, you need and inlet, overflow, and an outlet. It’s important that all the connecting pipe work be carefully planned in order to look as discrete as possible, and operate effectively and safely.
5-A pump will most likely be required to pressurize your water lines unless you wish to use a gravity drip irrigation set-up. It is important that all of your taps, valves, and water lines indicate that the water is not for potable use.
If your RWH harvesting system is for non-potable indoor use (toilet flushing) then we involve a licensed plumber for all interior plumbing work. Building permits are required for interior plumbing modifications in most areas of BC.
