Sump Pumps in Longmont, CO

Where should my Longmont sump water go?

Outside, onto ground that carries it away from the foundation. The City of Longmont runs the sanitary sewer and maintains the mains, while the property owner owns and maintains the sewer service line from the house to the main. Groundwater pumped into that line, through a floor drain, a laundry standpipe or a cleanout, adds flow the system is not designed to carry, and it can stress your own private line too. If your pump empties indoors, a plumber can reroute it to the yard. Keep the outdoor end off the sidewalk and driveway, where winter runoff turns to ice.

Does the age of my house matter?

Somewhat. Census survey figures put Longmont's median build year at 1991, with about 37% of homes built before 1980. A newer home usually has a builder-installed basin with a basic pump that may never have been lifted since closing. An older house closer to downtown may have a pump someone added years ago, sometimes with a hose for a discharge. Either way, if the pump is loud, rusted or slow to start, it is worth testing before the next spring melt or summer storm. Lots near St. Vrain Creek and other low ground can also see the pit run more often after wet weather.

Battery or water-powered backup on Longmont water?

A battery backup is the simpler path because it does not touch the drinking water. A water-powered unit connects to your supply line, and Longmont's Backflow Prevention and Cross-Connection Control Program has specific rules: new or replacement assemblies generally must be reduced pressure (RPZ) type unless the city approves otherwise, they need a miscellaneous permit from Building Inspection, and they must be tested after installation and every year by a certified tester, with results filed through the city's SwiftComply portal. That is a real ongoing commitment, so weigh it before choosing water power. Whichever you pick, a high-water alarm is a small addition that buys you warning time.

Permits and after-hours help

Longmont Building Services requires a permit for any changes to plumbing systems, so new discharge piping or a new basin should go through the city; a straight pump swap may not. For a sewer emergency after hours, the city directs residents to Longmont Police and Public Safety Dispatch. The plumber you reach can sort out which situation you are in.
