Rainwater Harvesting Lets Seattle Area Residents Opt Out of City Water

RAINWATER HARVESTING LETS SEATTLE AREA RESIDENTS OPT OUT OF CITY WATERDo you know that you can collect 624 gallons of water from 1 inch of rain with only 1,000 sq ft of roof area?  

That’s water that you can use for irrigation, toilet flushing, laundry, or even whole house potable (drinking) use. That’s right! 624 gallons. If you have a 1,500 square foot roof area in the Seattle area, this equates to 33,642 gallons of available water. Water that you don’t need to pay for. You can save money on your water, and sewage bill and, over time, pay for your system with that savings. Depending on the application of the captured rainwater, you can supplement your usage through a simple collection system for irrigation or by plumbing in your toilets and laundry facilities. Or, if you choose to have a whole house system designed and installed by a professional, you can eliminate your municipal water usage altogether and have city water as only a back up supply.

Water quality of collected rainwater after filtration and UV disinfection is above that of a municipal water supply, as long as the system is designed, installed and maintained properly. Annual costs of maintenance is much less than your current water bill and is easy to do. Periodic cleaning of your gutters and screening devices along with filter changes a few times a year and replacement of the UV bulb once a year is all there is to it.

Many people in the Seattle area are opting out of city water usage whether it is for potable or non potable use. Supplementary tanks with a small amount of storage can offset your water bill as much as 80%.

A decentralized private water system eliminates the possible threats to your drinking water from environmental concerns, water advisories, price increases,  additives such as chlorine and fluorides and possible rationing, such as in California. You are in control of the quality of your water and its use.Rainwater Harvesting Lets Seattle Area Residents Opt Out of City Water

Rainwater Collection is Viable Alternative to Well Water

rural residential rainwater harvestingRural residents are finding that rainwater collection can be a viable alternative to well water.  Since rainwater is generally cleaner than surface water and well water, a rainwater system that is properly designed and installed can supply a household with good, clean water for potable use.

In a residential setting, the average person uses 30 to 50 gallons per day.  For a 2-person household, that would be 3,000 gallons per month.  A 2,000 sq ft roof will yield over 44,000 gallons of rainwater with 36 inches of annual rainfall, which is more than enough to supply a residence.

Steel and plastic water tanks are economical to install when considering the cost of a having a drilled well.
