Do you know that the average annual rainfall of 36 inches in Seattle and a 2,000 square foot roof can collect over 44,000 gallons of rain annually? That’s over 120 gallons per day of potential usage; well enough to sustain a household of four.
A recent chemical spill in West Virginia emphasizes the vulnerability of our water supplies and reinforces the value of harvesting rainwater. A professionally designed and installed rainwater collection system will provide a significant amount of clean, safe drinking water for residential and commercial use.
The average home within Seattle city limits may not have much space for storage, however, with just 3,000 gallons of storage, a potable supplementary rainwater catchment system with 2,000 square feet of roof, can mitigate up to 70 percent of your city water use. With new slim line designs of water storage tanks, affordable and practical rainwater catchment systems are being installed within Seattle city limits.
With the cost of city water on the rise, potential disastrous effects such as the West Virginia spill, along with other incidents to municipal water supplies, rainwater harvesting is a viable, safe, and affordable alternative. Whether potable for full household use or non potable for irrigation, toilet, and laundry use rainwater collection is legal in Washington State and in Seattle.
Rainwater collection can create SAFE, decentralized water supplies.
