Does the water coming into the plant increase when it rains?

Yes, but not very much. The treatment plant only treats only water that goes down the drain in houses and businesses. All the rainwater flows into the storm drains that you see on the side of the road. That rainwater flows into the local creeks and eventually into the ocean.

It is very important not to let any garbage, used motor oil, or even soapy water from washing cars enter the storm drains because it will pollute our waterways.
