Three water districts, three sewer districts
Most cities have one water utility. Des Moines has several: Highline Water District, Lakehaven and Water District 54 supply water, and Midway, Southwest Suburban and Lakehaven handle sewer, depending on where you live (City of Des Moines, Community Services Directory). It matters when something goes wrong. The district owns the main and the meter; the pipe from the meter to your house, the side sewer to the street and everything inside are yours.
If water is surfacing in the yard, a meter is spinning with everything off, or several neighbors have backups at once, call your district as well as us. If it is only your house, it is almost always on your side, and that is our job.
Hillside homes and drainage
A lot of Des Moines is built on slopes that drop toward the Sound. Rain that runs downhill finds foundations, crawlspaces and daylight basements, so sump pumps, footing drains and floor drains matter more here than in flat neighborhoods. We replace failed sump pumps, add check valves and alarms, and clear floor drains that have silted up. Long side sewers on sloped lots can also sag or get into roots, which shows up as slow drains and gurgling toilets.
Water heaters in Des Moines homes
Condos and apartments near the marina often have a small electric tank in a closet; houses on the hill tend to have a gas or electric tank in the garage. When one fails, we talk through the options rather than swapping like for like.
| Option | Where it fits |
|---|---|
| Heat pump water heater | Garages with space around it; cheapest to run of the electric options |
| Gas tank | Houses already on PSE gas with a working vent |
| Tankless gas | Busy households that run out of hot water |
| Compact electric tank | Condo and apartment closets with no gas |
A heat pump water heater can also earn a PSE rebate for electric customers (PSE heat pump water heater rebate), which we file as a PSE Trade Ally. Whatever you pick, the new tank gets seismic straps per code.
Condos and townhomes
In a condo, a leak rarely stays in one unit. A failed water heater, a cracked supply line under a sink or a washing machine hose can reach the unit below within minutes. We find the source, stop it and repair it, and we can replace old braided supply lines and add leak sensors or automatic shutoffs to lower the risk. Tell us about your HOA’s rules on water shutoffs and work hours when you book.
Hidden leaks
Not every leak drips where you can see it. Signs of a hidden one include a water bill that jumps without a reason, a meter that moves with every fixture off, warm spots on a slab floor, a musty smell in a closet, or paint that bubbles on a wall. We test fixtures first, then isolate sections of pipe until we find the source, so we open only the wall or floor we need to.
Fixtures and remodels
We replace faucets, sinks, toilets, vanities and shower valves, add laundry and utility sinks, and move supply and drain lines when a kitchen or bath remodel changes the layout. On a larger remodel, a written plumbing number early on makes the rest of the budget easier to plan.
Common plumbing calls in Des Moines
- Slow kitchen and bathroom drains from grease, hair and soap buildup.
- Water heaters leaking at the base or out of hot water too soon.
- Running toilets and worn fill valves wasting water.
- Sump pumps that fail during the first big storm of the season.
- Low water pressure from a failing pressure regulator or older pipe.
- Frozen or split outdoor faucets after a cold snap.
Older pipe and repiping
Homes from the 1950s through the 1970s may still have galvanized steel supply pipe, which narrows with rust and shows up as weak pressure and brown water after the tap sits. Homes from the late 1970s into the 1990s may have polybutylene, a gray plastic pipe that is known to fail at the fittings. We can replace the worst runs or repipe the whole house with PEX or copper, and you get a written price for each option.
Plumbing permits in Des Moines
The City of Des Moines issues plumbing and mechanical permits through MyPermits Online and has a water heater checklist for replacements (City of Des Moines, permit applications and information). We check what your job needs, pull the permit and schedule the inspection.
When to call right away
- Water spreading that you cannot stop at a fixture valve: shut off the main valve first.
- Sewage coming up in a tub, shower or floor drain.
- A gas odor around the water heater: get out first, then call PSE or 911.
- Water dripping into the unit below in a condo or apartment.

Which water district serves my Des Moines home?
Des Moines is split among Highline Water District, Lakehaven and Water District 54 for water, and Midway, Southwest Suburban and Lakehaven for sewer (City of Des Moines, Community Services Directory). Your utility bill tells you which one to call about a main or meter.
Does a water heater swap need a city permit?
The city handles plumbing and mechanical permits through MyPermits Online and has its own water heater checklist (City of Des Moines, permit applications and information). We check what your replacement needs and pull the permit.
Does PSE pay anything toward a heat pump water heater?
If PSE supplies your electricity, yes: $1,000 on a qualifying unit, or $1,100 through Efficiency Boost, as of September 2026 (PSE heat pump water heater rebate). As a PSE Trade Ally for water heaters, we submit the paperwork.
What should I do if sewage backs up into a basement drain?
Stop running water in the house, keep people away from the water and call us. If your neighbors have the same problem, the blockage may be in the district’s main, so call your sewer district too.
