Jack is an enthusiastic and knowledgeable proponent of rainwater harvesting. He takes the time to explain the elements of his work and make suggestions. His years of experience in this work are obvious. I’m looking forward to learning how to better use the collection system that I have and exploring the options. Thanks for your support, Jack.

Product Water has been an incredible service from the first consultation and on, through multiple follow-ups to maximize the potential of our system. As environment-conscious first-time home owners in the Pacific Northwest, the system installed and maintained by Product Water delivered on its aim. Our front yard is now watered exclusively from the water we collect, and the water diversion system vastly reduces stain on the municipal waste-water system and therefore erosion on the Duwamish river, further supporting re-habitation efforts. They also helped us navigate the Rain Wise Rebate system so the city compensated us for the majority of the project. If you are eligible for the Rain Wise program or just wanting to expand your rain water collection and usage, we highly recommend working with Project Water.

I had a great experience working with Jack on my RainWise cistern project. After coming up with a plan we both agreed was the best option for my house, he let me know what to expect at each step of the process, which made it incredibly simple and convenient for me. I now have an effective rain management system in place, and, with the RainWise program, at a very minimal cost

How much money can we save?

In addition to saving money using rain as a supplemental source, you also benefit by establishing a convenient watering system and management capabilities. For projects storing 1000 gallons of rainwater the potential savings in 2024 were averaged between 500 to $1000 based on usage see this success story: Save $ 35,000 in 10 Years

 

Not with our help. We handle everything from design to installation. Rain water collection is a simple process once you understand the fundamentals. Please fill out the form at the bottom of the page, ask us your questions and we will set up a consultation by phone or site visit to begin the planning

.

It varies, but most installations take just a few days. Click to learn more about our efficient process.

 The biggest cost is the tank. Prices range between 200 to $5000. What you buy is a one time setup, done correctly will last a lifetime. It really is money well spent.

 Not really. For example, dirt naturally settles in the bottom of a rain tank over time. Keep your gutters reasonably clean, which keeps leaves from clogging it up. Every now and then take a close look at your system around the fittings on the bottom to determine if you have a slow leak. If you have a  leak gently retightened.
