In Corona, the City's Utilities Department provides sewer service and treats wastewater at its own reclamation facilities. The private line from your house to the City's sewer is repaired by a plumber when it clogs, cracks or fills with roots. Call the number on this page to be connected with a local plumber in Corona.

How a sewer line tells you it is failing
- Bubbling in the toilet bowl while a sink or tub drains
- Sewage at a floor drain, shower or ground-level cleanout
- Every fixture draining slowly, not just one
- Clogs that come back after the line has been cleared
- Lush grass or a damp spot along the route of the pipe
Corona's sewer setup and housing
The City of Corona Utilities Department provides sewer service to its water customers and treats wastewater at City reclamation plants such as Water Reclamation Facility No. 1. That keeps the public side under one roof: questions about the main, or an overflow in the street, go to the Utilities Department at (951) 736-2234, which offers an after-hours Stand By option.
Corona's housing ranges widely. The historic district along Grand Boulevard, the Circle City loop, and the South Main Street Palms District hold some of the city's older homes, where laterals can be clay or cast iron with joints that let roots in. Newer neighborhoods such as Eagle Glen generally have plastic pipe, where the usual faults are a settled section or a joint pulled apart by soil movement. Every home is on a slab, so the first run of drain is usually under the floor.
What drives the cost
- Depth. A lateral that sits several feet down takes longer to reach than a shallow one.
- Location of the break. Under the slab, under hardscape or out in the yard each calls for a different approach.
- Extent of damage. One cracked joint can be a spot repair; a run of broken pipe usually means lining or replacement.
- Permits. The City of Corona Building Division handles plan review, permits and inspections, with applications and inspection requests online through eTRAKiT.
When you call
An independent plumber who covers Corona picks up the job. Share what you have seen, how old the house is and whether the line has been cleared before. Most visits begin with clearing the blockage, then a camera inspection to locate damage and measure its depth, followed by a recommendation you can weigh before any digging starts. If you know where the cleanout is or roughly where the line leaves the house, say so; it shortens the first visit.
