Understanding your sewer service charge

A sewer service charge pays for the collection, treatment, and management of wastewater from homes and businesses. It supports the pipes, pumps, treatment facilities, maintenance crews, testing, and regulatory work needed to protect public health and the environment.

For Susanville customers, the amount shown on a utility bill may be separate from water usage or other municipal services. Learning how the charge is calculated can make your bill easier to review and help you identify questions before they become payment problems.

What the sewer charge covers

Wastewater begins when water leaves a sink, toilet, shower, appliance, or other indoor drain. Through the sanitary sewer system, it travels to treatment facilities where solids, organic material, and other pollutants are removed before the treated water is discharged or managed according to environmental requirements.

Your sewer payment helps fund daily operations as well as long-term infrastructure needs. Those expenses can include sewer main repairs, service inspections, pump maintenance, emergency response, employee training, equipment, laboratory testing, and improvements required as the system ages.

A sewer fee is generally different from a stormwater charge. Sanitary sewers carry wastewater from buildings, while storm drainage systems manage rainwater and runoff from streets, roofs, and other surfaces. The city’s stormwater drainage guide explains why these systems serve different purposes.

How the amount may be calculated

Municipal utilities commonly use a fixed monthly sewer rate, a volume-based charge, or a combination of both. A fixed portion provides predictable funding for system availability and basic maintenance. A usage component may reflect the amount of water entering the wastewater system.

The calculation method can vary by customer class. Residential accounts, commercial properties, multifamily buildings, and special users may have different rate structures because they place different demands on collection and treatment facilities. Some accounts may also be billed using an estimate or a defined measurement period.

Your bill should identify the billing period, account category, sewer line item, and amount due. If the charge appears to be based on water consumption, compare the sewer line with the water usage shown for the same period. Current rates and account-specific rules should be verified through official city utility information rather than an older bill or informal source.

Bill item	What it generally represents	What to check
Sewer base charge	A recurring cost for access to and support of the wastewater system	Whether the amount is fixed each billing period
Sewer usage charge	A cost connected to measured or estimated wastewater volume	The usage period and measurement method
Water charge	Payment for treated drinking water supplied to the property	Whether water and sewer amounts are listed separately
Stormwater or drainage fee	Support for runoff collection and related infrastructure	Whether it is a separate municipal service
Late fee or adjustment	A payment, correction, credit, or past-due balance	The description and date of the transaction

Why sewer rates can change

Rates may be updated when operating expenses, energy costs, chemical prices, labor, construction materials, or regulatory requirements change. A city may also adjust charges to maintain reliable service, replace failing infrastructure, or build reserves for major capital projects.

A rate change is generally adopted through a public municipal process. Notices, staff reports, public meetings, ordinances, or published rate schedules may explain the reason for a new amount and the date it takes effect. When reviewing a changed bill, compare the billing date with the effective date of the current schedule.

Usage can also make a bill vary from month to month. A leaking toilet, running faucet, irrigation connection, or plumbing problem can increase water consumption and may affect a sewer charge when the calculation uses metered water. Promptly repairing leaks can reduce waste and help prevent unexpectedly high utility costs.

Reading your utility bill carefully

Start by confirming the service address and account number. Then review the beginning and ending meter readings, billing dates, current charges, previous balance, payments, credits, and any adjustment. A charge that seems unusual may result from a longer billing cycle, a corrected reading, a new rate, or a prior balance.

Keep several bills together so you can compare patterns rather than relying on one month. A sudden increase deserves attention, especially when household activity has not changed. Check indoor plumbing, listen for toilets that continue running, and inspect visible areas for moisture or leaks.

If you recently moved, changed occupancy, remodeled, installed fixtures, or experienced a water leak, note the dates. Those details can help utility staff determine whether the charge reflects normal billing, a change in account status, or a possible meter or plumbing issue.

Ways to manage wastewater costs

Most sewer charges are connected to the service provided, so conservation may not reduce a fixed base amount. However, efficient water use can reduce the volume entering the sewer system when the bill includes a usage-based component. Water conservation also helps protect Susanville’s broader utility resources.

Practical steps include repairing dripping fixtures, replacing worn toilet flappers, running dishwashers and washing machines with full loads, and avoiding unnecessary indoor water use. Never pour grease, paint, solvents, wipes, or other unsuitable materials down a drain. They can cause blockages, damage equipment, or interfere with wastewater treatment.

Questions to resolve before paying

If the amount does not match your expectations, gather the bill, recent payment records, meter information, and any relevant repair documentation. Contact the appropriate city utility office using the current phone number or online resource listed by the City of Susanville Public Works Department.

When requesting an explanation, ask which rate schedule applies, whether the charge is fixed or usage-based, what dates were used, and whether an adjustment or estimated reading appears on the account. Ask about payment arrangements or dispute procedures promptly if the balance may be difficult to pay by the due date.

Helpful account review steps

• Compare the sewer line item with at least two or three previous bills.
• Check the billing period, rate category, meter readings, and effective date of any rate change.
• Inspect toilets, faucets, appliances, and exposed plumbing for leaks.
• Keep copies of bills, payments, repair invoices, and communications with the utility office.
• Use official city contacts for questions about rates, balances, adjustments, or service concerns.

Understanding the charge makes it easier to budget for essential municipal services and recognize an unusual bill early. Review your next statement, confirm the current rate information, and contact Susanville Public Works when you need an account-specific explanation or assistance.
