Rivergrove Water District’s water source is groundwater that comes from wells we have drilled into the Columbia River Basalt Aquifer. We currently have three wells that adequately supply our current demand.

The rate that applies to most of our customers is for a 3/4-inch water meter. For this sized meter, the bi-monthly rate is as follows: a service fee of $44.11 and a water usage fee of $3.55 per 100 cubic feet. (There are approximately 750 gallons of water per 100 cubic feet.). Larger meters have different rates and the rate schedule for these meters is available at the District office. 

The District offers many convenient ways to pay your bill.

Currently, the District does not offer paperless billing.  We have explored paperless billing and found it to be cost prohibitive to a District of our size.  It would only be a feasible option if 1/3 of our customers opted for this feature.  The majority of our customers prefer paper statements.  Based on our billing volume, we can provide the billing invoice, postage, single page colored…

It is not possible to quote an “average cost” for water. The cost depends upon many variables including size of the family, water-use habits, and how often you irrigate your yard.

First, turn off all the water both inside and outside your home. Make sure there is no water usage while you check the meter. If the dials or hands are turning, water is going through the meter. This would indicate there is a leak somewhere in your plumbing.

A minimum of 4 microbiological water samples are taken at various sites in the District Water system each month. We also test the water for chemical makeup and possible contaminants levels at Alexin Analytical of Oregon, a state Certified Water Testing Laboratory. If you wish additional information about our water testing and results, our lab telephone number is (503) 639-9311.

The District has a curb stop that shuts off each meter. Customers are not allowed to operate the curb stop. The curb stop is property of the Water District and it takes a special tool to turn the handle. If a customer uses this stop and turns it off with a crescent wrench or any other type of tool, it could result in damage to the curb stop. When the curb stop is damaged the entire main has to be…

If you have a water emergency, call the office at (503) 635-6041 during normal business hours, Monday - Friday, 7:30 am to 4:00 pm, and speak with our staff.  If an emergency occurs after office hours, call the same number and our answering service will make the necessary contact to our on call water operator.  The on call operator will then contact you directly to evaulate the situation and…

Disaster can strike at any time and in any community. Rivergrove Water takes special measures to protect both the availability and quality of your water supply. Although no amount of preparation can prevent a disaster, you can plan to limit its effects. One of the most important supplies to have on hand in the event of a disaster is safe drinking water. 

As a general rule, the District maintains, repairs, or replaces the water meter as well as the box in which it is housed. Please contact the office as soon as possible to report a problem. If a repair or replacement is required due to negligence of the homeowner, the District will charge a fee for the repair and/or replacement work and the customer will be billed accordingly.  Each customer should…

No!  The Rivergrove Water District only provides potable water to its customers. The City of Lake Oswego provides some sewer service in some areas of the District. If you are on sewer or would like more information about sewer service please call Lake Oswego at (503) 635-0265.

Fluoride is not added to the water. Our water quality lab tests have shown the amount of natural fluoride to less than 0.5 parts per million. For comparison, one part per million is equivalent to 1 cent in ten thousand or drop in a million drops. This means that in one million drops of water there is less than ½ drop of fluoride.

The water from our wells is moderately hard. For additional information concerning hardness and customer choices on water softening, please check out our resources on ways to deal with hard water.

No! A standard vinyl garden hose is made with substances to keep it flexible. These chemicals can be harmful to you.

We recommend using cold water. Hot water is more likely to contain rust, copper, and lead from your household plumbing and water heater.

Since 1957, the Rivergrove Water District has never had to ask customers to conserve water. That does not mean that conservation of this natural resource will not be needed in the future and that customers should make an effort to use it wisely.
