Frequently Asked Questions

Q: What is a roofwasher?
A: It is a device which filters out the large particles and keeps them from entering into the device holding the rainwater (rainbarrel or cistern).

Q: Are mosquitoes kept out of your systems? How about sediment and leaves?
A: These are kept out of the system by the roof washers which are installed.

Q: What is a cistern?
A:  A cistern is a larger water storage device.  It can be made out of plastic, cement, metal or wood.

Q: I am planning on system, could you help me find pumps, cisterns and other materials for the job?
A: Yes, I can provide consulting assistance and help you find the materials for a rainwater system.

Q:    What can I use the water for?
A:     It is very easy and cheap to use it for irrigation.  If you want to use it inside your home, it is allowable; however, an appeal must be done for a permit.  A licensed plumber must do the work inside your home.  It does cost more to bring it inside your home, but it is the best use for the water.

Q:    What type of systems do you create and install?
A:    Anything you are interested in which I can do.  Some arrangements I have done:

  • Vertical rainbarrels (standard)
  • Horizontal rainbarrels (on pallet racking)
  • Above ground cisterns for irrigation use or indoor water use
  • Below ground cisterns for irrigation use or indoor water use
  • Thai Jars (hand made cement cistern)

Q:    What is the maintenance for these systems?
A:    If you have an asphalt composite roof you will need to look at the roofwasher about once every three months to make sure it is not covered/clogged with grit on the screen.  About once every year or two when the barrels or cisterns are empty you should inspect them and clean them out.

Q:    What about asphalt composite roofs? Is it safe to water my plants with it? Drink it?
A:     I would not recommend drinking this water without a filter.  However, it is safe enough to water your garden with this water.  This water does not have chlorine in it like our drinking water.

Q:    What are your fees?
A:     Please see the fee document on the Products and Prices page.

Q: Are there other colors than blue for the rainbarrels?
A: No. I am reusing these barrels and they come in this color.  Clients have painted them before.  I have used Zinser primer on barrels with success. I have found Fusion spray paint works well on plastic. I will place reed fencing around the barrel for an additional cost of $40 per barrel.

Q: Can I use a white barrel or cistern?
A: No. They will allow sunlight to enter the cistern and allow algae to grow inside.

Q: What are the barrels and cisterns made of?
A:  High Density Polyethylene (HDPE).  The cisterns are rated for potable water use.

Q: Are there any tax incentives or other incentives for using rainwater?
A:  The City of Portland has the Downspout Disconnection Program and the Clean River Rewards Program.  They provide some monetary assistance.
