How to investigate an unexpectedly high water bill

An unusually high water bill can be alarming, especially when your household habits have not changed. A larger charge may result from a longer billing period, a rate adjustment, seasonal outdoor watering, a reading issue, or water escaping through a fixture or underground line.

The fastest way to identify the cause is to compare the current statement with earlier bills and check actual water use. Focus on the consumption shown in gallons or units, since the total amount due can also change because of service charges, sewer fees, taxes, or other account adjustments.

Residents can use the City of Susanville Public Works Department’s official water resources to find utility information, conservation guidance, payment resources, and available contacts. Keep the bill nearby while working through the checks below.

Start with the details on your bill

Review the service dates first. A bill covering more days than usual can show greater consumption even if daily use remained steady. Compare the number of billing days, the previous meter reading, the current reading, and the total gallons or units used.

Next, separate water consumption from the total balance. A higher fixed charge or a change in sewer-related fees may affect the amount due without indicating a plumbing problem. If the usage figure itself is much higher than normal, investigate the property before assuming the rate is responsible.

Look at several previous statements rather than relying on one month. A gradual increase may point to irrigation or changing household routines, while a sudden spike is more consistent with a leak, a faulty fixture, or a meter-reading concern.

Check the meter and household fixtures

When no water is being used, turn off faucets, washing machines, dishwashers, ice makers, and irrigation systems. Locate the water meter and watch the display or flow indicator for several minutes. Movement during a period of complete inactivity can signal water use somewhere on the property.

Test toilets carefully because silent toilet leaks can waste substantial amounts of water. Place a few drops of food coloring in the tank, wait without flushing, and check whether color appears in the bowl. Also inspect faucet connections, water heaters, hose bibs, washing machine hoses, and any damp areas beneath sinks.

If the meter appears damaged, inaccessible, or inconsistent with your observations, avoid tampering with it. Review the city’s meter replacement guide for information about scheduling service and addressing a possible meter issue.

Investigate outdoor water use

Outdoor watering is a common reason for a seasonal increase in consumption. Check irrigation timers after power interruptions, inspect sprinkler heads for broken or misdirected spray, and look for wet soil or pooling water near valves and garden lines. A hose left running or a leaking connection can also affect a full billing cycle.

Compare the bill with recent weather and landscaping activity. New plantings, lawn establishment, dust control, or unusually dry conditions may have increased watering time. Make sure automatic systems are programmed for the current season and do not operate during rain or when the property is vacant.

An underground irrigation leak may not be visible at the surface. Signs can include unusually lush patches, sinking soil, persistent mud, or water flowing toward the street. Shut off the irrigation supply when possible and arrange qualified plumbing or irrigation assistance if the problem is on the customer side of the meter.

Compare possible causes before calling

The pattern of usage can help narrow the investigation. A one-time spike after a known event may have a simple explanation, while continued high consumption deserves prompt attention. Record meter readings, dates, and any repairs so the billing or utility staff can understand what happened.

What you notice	Likely area to check	Useful next step
Higher use during warm months	Lawn irrigation, gardens, pools, outdoor washing	Review timers and inspect sprinkler equipment
Continuous meter movement with fixtures off	Toilet, service line, irrigation, or plumbing leak	Isolate fixtures and arrange leak repairs
Bill total higher but usage is similar	Rates, fixed charges, or other account fees	Review the statement details and current utility information
Reading seems inconsistent with the property’s use	Meter access, reading, or account concern	Contact Public Works with the statement and meter details
Increase after guests, construction, or a filled pool	Temporary additional demand	Compare the event dates with the billing period

Do not wait for the next statement if the meter continues to register flow while all known fixtures are off. A small leak can become a costly repair, and a major leak can damage structures, landscaping, or nearby public infrastructure.

Contact the right resource

If your inspection does not explain the increase, gather the account number, service address, billing dates, previous and current readings, and notes about any leak checks. Clear details make it easier for utility staff to review the account and identify whether the concern involves consumption, billing, or the meter.

For a possible reading discrepancy or account question, contact the City of Susanville Public Works Department through its published channels. If water is actively escaping, shut off the property’s supply when safe to do so and seek urgent plumbing assistance. Problems involving public mains, streets, or other city infrastructure should be reported through the department’s emergency or service contacts.

A water bill review may also reveal that conservation changes can reduce future costs. Ask about available guidance on efficient watering, fixture performance, and responsible household use rather than making assumptions based only on the dollar amount.

Practical ways to prevent another spike

Once the cause is identified, make a few targeted changes and continue monitoring the meter. Small checks are more effective when they become part of a routine, especially before and after irrigation season.

• Read the meter at the same time each week and record the result.
• Inspect toilets, faucets, hose bibs, and exposed pipes for leaks.
• Adjust irrigation schedules for weather, plant needs, and seasonal conditions.
• Replace worn washers, valves, supply lines, and inefficient fixtures promptly.
• Review each statement for billing days, usage units, and changes in charges.

If a repair was completed during the billing period, compare the next statement with your recorded readings. A lower usage level can confirm that the leak or excessive-use source was corrected. If consumption remains high, continue isolating parts of the property and request professional assistance.

Acting early can protect your household budget, conserve Susanville’s water supply, and prevent a small problem from becoming a major repair.
