How our Process Works
Every project is different, but our priority is to bring your rainwater solutions and ideas to life and accommodate all your water demand needs.
We will work with you through the design process to choose the system components best suited for your project, provide you with the system blueprints and refer you to trusted suppliers and installers.
Our approach starts with calculating your required water storage capacity and continues with a complete system design with all its components.
Step 1: Calculating the water storage capacity needed to sustain you through the year. But before we start, we need to know the following:
How much water do you use and what are your water habits?
The amount of water needed for your indoor and outdoor water demands.

Water Storage Capacity
How much Water can you collect?
The amount of water you can collect and store via rainwater harvesting throughout the year

Step 2: Designing the rainwater harvesting system with all the system components, including
Conveyance System & Pre-Storage Filtration
For the cleanest water in your tank
- Design a conveyance system including gutters, downspouts, and piping for collecting and directing capture rainwater to the tank(s).
- Provide the best options for pre-storage filtration to ensure the maximum cleanliness of the water in your tank(s).
Water Storage Tank
To ensure sufficient tank capacity
- Provide you with customized storage tank(s) options to ensure that they meet all your requirements.
- Establish the most suitable location for your tank(s) to:
- Work with your landscaping
- Ensure easy access for cleaning and maintenance
- Protect your tank and property from any damage
- Meet all the necessary codes and standards
Post-Storage Filtration & Distribution
So your water is safe to use
- Advice about a filtration system suitable for intended water uses as per local requirements and codes.
- Refer you to water filtration and treatment specialists and certified plumbers to ensure your rainwater is safe to use.
The Key to successful Rainwater Harvesting is a properly sized water storage.

Frequently asked questions
Rainwater is fresh precipitation straight from the sky that hasn’t touched the ground.
Water demand includes all indoor and outdoor uses. To calculate your water storage requirement, you have to understand your monthly indoor and outdoor water demands.
You can collect rainwater for domestic uses, agricultural or commercial uses.
The most common uses of rainwater include non-potable uses such as toilet flushing, gardening, and car washing or potable uses such as drinking and cooking, dishwashing, and showering.
Let us help you determine how big your storage tank should meet all your water demand needs.
Let us start with sizing of your water storage tank but first we have to ask you a couple questions about your water situations.
Let us help you to determine the size of your water storage tank to ensure that you will
- Have enough water for the entire year
- Not run out of water in the middle of the summer
- Avoid subsidizing your water with untested water from outside sources, and
- Minimize the excessive overflow from the cistern in the winter months.
The total amount of water you can collect from your roof via rainwater harvesting depends on:
- The area of your roof (the area measured as the horizontal projection of the roof).
- The efficiency of your rainwater harvesting system, including the system losses due to evaporation, type of roofing material, and any losses or leaks in the water conveyance system.
How to calculate your harvest potential?
Average Rainfall x Efficiency x Roof Area
It is helpful to understand the differences between metric and imperial measurement systems used in North America. Check the conversion system.
For example:
- 1″ of rain on 1 square foot of roof area produces 0.52 Imperial gallons of water
- 1 mm of rain on 1 square meter of roof area produces 1 Litre of water
The roof area is measured by the horizontal footprint of the top, not its surface area.
Length x Width of each segment of the roof Area
The catchment area should be of a material suitable to allow for the end-use of the collected rainwater
Pre-storage filtration prevents coarse material from entering the system and removes suspended
contaminants (i.e., gutter screening, debris filters).
Storage tanks and conveyance systems have to comply with standards for their construction materials
and potable water.
