Actionable Steps

Checking Your Bill

Look for 'Water Usage' or 'Sewer' rates on your last utility bill. Sewer rates are often billed based on water usage.

⚠️

Safety Warning: Some cities offer a 'pool fill' credit on sewer charges. Call your utility company to ask.

Pro-Tip

If you are refilling a high volume, some utility companies will 'forgive' the sewer portion of the bill since the water didn't go down the drain. Always call and ask!
