Wastewater meter service charge plus a wastewater usage rate per 1,000 gallons of wastewater.

Ways to pay less

• Seniors 65+: lower trash, water and sewer base rates. Customers 65 and older can sign up for a reduction on residential trash and recycling and on the fixed water and wastewater rates. How: Sign the agreement form and show proof of age; see the city's Senior Discount page.
• Sump pump certification avoids a stormwater fee. Sewer accounts without a sump pump certification on file are charged a storm water fee. How: Call (816) 532-3897 to schedule a sump pump inspection.
• Winter sewer averaging. You can elect the residential average for the City of Smithville when signing up for a utility account. How: To bill actual use instead, opt out before March 1 by calling City Hall at 816-532-3897.
