4. What should I do if I see liquid flowing out of a manhole?

5. Is it okay to dump grease down my house drains?

No, dumping grease down your house drains will cause grease buildup in your drain lines. Some people believe that if you mix hot water with the grease it will not clog your lines. While this practice may not clog the lines in your immediate house, by the time the grease gets to your lateral it will have cooled enough to build up in your lateral. Keep in mind, you are responsible for the maintenance of your lateral and calling out a plumber for this type of maintenance can be very expensive.

6. Where is the wastewater treated?

Wastewater collected in the City of Beaverton flows to one of two sewage treatment plants, which are operated by Clean Water Services (CWS). One is located at the end of Southwest Hall Boulevard in Tigard, and the other is located on Southwest River Road in Hillsboro.

7. Is it ok to flush plastic items down the toilet?

No, flushing plastic items and other non-biodegradable material, such as many brands of baby wipes, down the toilet causes problems in sewer lines. The material will hang up in your line and cause blockages. If the material reaches the treatment plant it will cause problems at the treatment facilities also.

8. Is it ok to dump car oil down the sanitary drain system in my house?

No, oil causes the filtration system at the treatment plant to fail and the filtration system must be cleaned and replaced causing thousands of dollars in damage.

9. Is there anything to keep in mind when I landscape my yard?

When planting trees or other shrubbery consider the location of your sanitary lateral so as not to plant over or near it. The roots can enter into sanitary laterals and cause clogs. Should roots block your sanitary lateral and you have had the roots cleared out of the line, consider using a root abatement to decrease the chance of the roots reappearing soon after removal.
