How to Use This Schedule

Factors That Affect Pumping Frequency
Household Size
More people = more wastewater and solids entering the tank daily
Tank Capacity
Larger tanks can hold more solids before needing pumping
Water Usage
High water use pushes solids through before they settle properly
Garbage Disposal
Adds significant solids to the tank, requiring more frequent pumping
Water Softener
Can disrupt bacterial breakdown and increase pumping frequency
Climate
Sacramento's dry climate can affect bacterial activity in the tank

Common Questions
Answers to frequently asked questions about septic pumping schedules
How do I use the septic pumping schedule table?▼
Find your tank size in gallons in the left column, then look across to find your household size (number of people). The number shown is how many years you can wait between pumpings. For example, a 4-person household with a 1,000-gallon tank should pump every 2.6 years (about every 2-3 years).
What if I don't know my septic tank size?▼
Most homes with 3 bedrooms have a 1,000-gallon tank, while 4-5 bedroom homes typically have a 1,500-gallon tank. You can find your exact tank size on your original installation permit, septic system diagram, or by calling us for an inspection.
Does Sacramento have specific septic pumping requirements?▼
California recommends pumping every 3-5 years for most residential systems. Sacramento County requires septic inspections during property sales and proper maintenance records. Annual inspections help determine the optimal schedule for your specific system.
What factors might require more frequent pumping?▼
You may need more frequent pumping if you have a garbage disposal, use a water softener, have guests frequently, do lots of laundry, or notice warning signs like slow drains, odors, or standing water near the drain field.
Can I wait longer than the schedule recommends?▼
No. The schedule shows maximum intervals. Waiting longer risks system failure, sewage backups, drain field damage, and groundwater contamination. These repairs cost thousands more than regular pumping.
