Sump pumps and backup systems in Green Bay, WI
With clay soils and a high water table near the bay, a sump may run for weeks each spring. Here is what a dependable setup looks like.
A sump pump sits in a crock at the low point of the basement, collects water from drain tile and from under the slab, and pumps it outside when the water reaches its float switch. A backup pump, running on a battery or on household water pressure, takes over if the main pump fails or the power goes out. For Green Bay-area homeowners, a sump system sized for spring melt, with a backup and a discharge line that freezes as little as possible, is what stands between a heavy thaw and a wet floor.
Is your pump struggling?
- It runs nonstop through March and April
- It hums but doesn't pump
- Water rushes back into the crock after each cycle
- The discharge line freezes in winter
- It trips the breaker or makes grinding noises
- There's no backup, and the basement is finished
What goes into a good system?
- A properly sized primary pump chosen for how fast your crock fills in a wet spring.
- A check valve so pumped water doesn't fall back.
- A backup pump. Battery backups run during outages; water-powered backups use municipal water pressure and don't need a battery, where local rules allow them.
- A high-water alarm to warn you before water reaches the floor.
- A sealed lid to keep debris out and pit moisture in.
- A freeze-resistant discharge, sloped to drain fully, often with an overflow fitting near the house in case the outdoor line freezes.
Where should the water go?
Into the yard, away from the house and your neighbors, never into the sanitary sewer. NEW Water, which treats wastewater for 15 municipal customers in Northeast Wisconsin, identifies prohibited sump pump connections to the sanitary sewer as a source of the clear water that can push its flows to three to five times normal during wet weather. That extra water raises treatment costs for everyone and can contribute to sewer backups. If your pump is tied into a floor drain or laundry tub, ask the company about rerouting it outside.
What affects the cost?
- Reusing an existing crock or installing a new one
- Pump type and capacity, plus the type of backup
- Discharge length and freeze protection
- Electrical or plumbing work needed for backups and outlets

Common questions
Can my sump pump drain into the sewer in Green Bay?
No. NEW Water lists sump pump connections to the sanitary sewer as prohibited, because clear water overloads the system during wet weather. Discharge should go outside.
How do I keep my sump discharge line from freezing?
Lines should slope so they drain completely after each cycle. Many installers add an overflow fitting near the house so water can still escape if the buried or outdoor line freezes.
What kind of backup sump pump is best?
Battery backups work during power outages; water-powered backups rely on municipal water pressure. The right choice depends on your water supply, local rules and how long outages last.
