Sump pumps in Fargo: the clear-water rule and winter waiver
Updated · Editorial team; not yet technically reviewed
Short answer
Fargo prohibits discharging sump pump, roof and foundation drain water into the sanitary sewer. Pumps must discharge outdoors, with a seasonal waiver allowing a sanitary connection from October 1 to March 31, when sewer flows are lower. The rule exists because clear water overloads the sewer and pushes sewage into basements.
What's different in Fargo
Section 22-0432 of Fargo's ordinances prohibits connecting surface or ground water, including roof drains and foundation drain tile, to the sanitary sewer. [1]
Fargo created its Sump Pump Program in May 2001 to reduce property damage from sanitary sewer backup. [1]
A seasonal waiver allows discharge to the sanitary sewer from October 1 to March 31; it's prohibited April 1 to September 30, and random inspections may happen then. [2]
Waivers are requested at 701.461.SUMP (701.461.7867) or online, and carry an added monthly fee on the utility bill. [2]
Summer versus winter setup
| Period | Allowed discharge |
|---|---|
| April 1 – September 30 | Outdoors only; random inspections possible |
| October 1 – March 31 | Sanitary sewer allowed with a seasonal waiver (monthly fee) |
A setup that switches cleanly
- A valve or quick-disconnect so the discharge can be routed outdoors in spring and to the waiver connection in winter.
- An outdoor line that slopes to drain, so it doesn't hold water and freeze.
- A discharge point far enough from the foundation that water doesn't cycle back to the pit.
- A battery backup for spring melt and summer storms, when the pump runs most. See sump pump repair and installation for pump sizing and backups.
