Frequently Asked Questions

In these uncertain times. Rainwater collection and storage is essential to everyone. We need good quality clean water for our homes, schools and businesses. If you are thinking of implementing a potable rainwater system. You may have questions. Olympic has answers.

Why Rainwater?

Rainwater is free of  harmful contaminents. The earth, sun and atmosphere imitate a distiller. Creating an excellent quality of water that has an improved taste, smell and look over conventional groundwater.

How much rainwater can I collect?

1 inch of rainfall generates 0.6 gallons per square foot of roof area. So if you have a  2000 square foot roof. You can collect about 1000 gallons for every inch of rainfall.

What size storage tank do I need?

A family of four requires about 140 gallons per day. Thats nearly 4500 gallons per month. The dry season  can last up to three months. So a family of four might require a 15,000 to 20,000 gallon

Is the water from my roof safe to drink?

The rainwater collected from the roof, runs to a flush diversion system. Diverting the first 5% of water harvested. Which contains the bulk of the solids from the roof. Once the water is stored in the antimicrobial tank. It is pumped through an inline sediment and charcoal filter. Then finally it passes through a UV Purification canister. The water harvested from your roof with our systems is better quality than any municipal or groundwater available in our service areas.

What roofing material is best for collection?

Standing Seam Metal, Corrugated Metal, Asphalt/Bitumen, Composite Shingles, Clay Tile, Concrete Tile, Slate Tile, Solar panels and Painted Tile. All are acceptable for whole house potable systems. We employ a three part filtration system to ensure you're getting the highest quality drinking water. Roofing materials that should be avoided are cedar shakes and any lead based roofing.

Where does the tank go?

We can make an assessment of your property. Considerations for elevation, tank placement, plumbing, electrical and location of the filtration system can be made at that time. If you are building a new home we can discuss your needs with your builder and provisions can be made to make the transition to rainwater completely seamless.
