Alleman has two kinds of water. Homes in town get treated river water from Des Moines Water Works, which took over the city’s water service on July 1, 2007. Some homes outside town rely on a private well; the state lists 71 household wells in the surrounding township. Each needs its own plan, and the records below show why.

Alleman once had its own water system. EPA records list city wells named for 1964, 1975 and 1996, plus a small plant listed as the South Plant. EPA’s record for the old system lists 130 service connections. It closed on June 29, 2007. Two days later, Des Moines Water Works began full water service to the city. It also bills Alleman’s garbage and recycling.
Today Alleman is folded into the Des Moines column of the regional water quality report. EPA’s list of Des Moines Water Works facilities includes a 0.3-million-gallon elevated tank under Alleman’s name. The water is softened at the plant to a goal below 150 mg/L. That goal still sits inside the U.S. Geological Survey’s “hard” band of 121 to 180 mg/L, so a home softener is still worth a look.
Outside city service, the water comes from your own well. Iowa’s well database lists 71 household wells in the township around Alleman, including some that have been plugged. About half are 200 feet or deeper.
Since 2016, the state has 12 private-well nitrate results from 7 wells in that township. The highest was 1.0 mg/L, far below the 10 mg/L standard. The five arsenic results there, from 2016 to 2023, were all at or below 0.001 mg/L.
Your own well can still differ. Iowa’s Private Well Grants program covers a free nitrate and bacteria test each year through Polk County, plus arsenic and manganese every three years. Kind Water Co adds a free screening for hardness, iron, TDS and nitrate. For private wells we also offer Whole-Home Nitrate Removal. It starts with a lab test for nitrate and arsenic; we choose the system from those lab results and test again once it is installed.
In town, on city water: expect water that has already been through a softening plant and lands near the 150 mg/L goal. A softener set from your own test takes out the rest of the scale-makers. A carbon stage is there if chlorine taste bugs you, and an under-sink RO gives the kitchen its own drinking faucet.
Out of town, on a well: begin with the free county test, then let us add our free hardness, iron, TDS and nitrate screening. For a deep well we usually look at a softener first, and an iron filter if the test calls for it.
Homes on city water should read the Des Moines Water Works annual report. In the 2026 edition, Alleman’s results sit under the Des Moines heading, marked with a footnote. Our Des Moines water report draws on that same utility.
For an Alleman postal address beyond city service, identify the rural utility or individual well. A city report cannot establish water quality for a private well.
A kitchen RO system provides a dedicated outlet for drinking and cooking water in Alleman. Compare tank storage and tankless output, then review inlet pressure, cabinet space, a faucet position, drain connection and filter access. Tankless equipment needs power; refrigerator piping is confirmed as part of the requested scope.
A water softener reduces calcium and magnesium for less scale, fewer shower deposits and less soap film. In Alleman, we size the system from measured hardness, daily water use and simultaneous fixture demand, then program regeneration for the selected capacity. If a softener is already installed, compare incoming and treated water before deciding between repair and replacement.
For an Alleman installation, we check people in the home, bathrooms, simultaneous water use, measured hardness and available flow. Then we review pipe size, existing equipment, a suitable drain, electrical access, bypass position and space for tanks and salt access. Under-sink RO also needs cabinet room, a faucet position and a drain connection; tankless equipment needs power. This makes the written recommendation useful before installation day.
For an Alleman home with recurring disinfectant taste or odor, compare a whole-home carbon stage with kitchen treatment. Carbon type, media volume, available flow and contact time are selected for the actual supply. Carbon does not remove calcium and magnesium, so softening serves a separate scale-control goal.

A private well near Alleman needs a plan for that property. Bring the latest laboratory results for bacteria, nitrate and other concerns; we add hardness, iron, TDS and nitrate screening and assess pump flow, pressure and sediment. Treatment may combine softening, iron or sulfur treatment, sediment filtration and a suitable drinking-water RO system. A neighboring city’s report cannot describe an individual well. Polk County Environmental Health offers private-well testing for coliform, E. coli, nitrate, arsenic and manganese. Confirm eligibility and scheduling with the county.

If an existing softener in Alleman stops using salt, leaks, runs constantly or leaves hard water, start with diagnosis. Share the brand, model, error code and an optional photo of the valve or plumbing. We assess bypass position, brine draw, controls and the condition of serviceable components, then explain repair versus replacement, parts availability and the cost before proceeding. Ownership includes salt for a salt-based softener, carbon-media replacement and the selected RO filter and membrane schedule. After an Alleman installation, keep the settings and model information, monitor salt and leaks, and arrange a service check if water use or the supplier changes. Whole-home coverage includes lifetime parts, five-year media and one-year labor under the written terms; RO warranty is confirmed for the selected model.
Share the Alleman address, water supplier or private-well information, household size and the problem you want solved. An optional photo of the current valve, plumbing and under-sink space helps plan a retrofit or repair. Call the Des Moines team at 515-709-4674 or request the Central Iowa installed quote.

First, check your supply. In town, Alleman homes get plant-softened river water from Des Moines Water Works, with a hardness goal under 150 mg/L. Outside town, some homes use a private well, and that well’s own test sets the plan. City homes often pair a softener for leftover hardness with carbon or a kitchen RO. Well homes may also need iron filtration, depending on the lab results.
A Kind Water Co tech checks hardness, iron, dissolved solids and a nitrate screening reading from a tap inside the house and looks over any softener or filter already in place. For an Alleman address, step one is confirming Des Moines Water Works service or a private well, because the gear differs. A written plan follows with equipment, install scope and timing.
If an existing softener in Alleman stops using salt, leaks, runs constantly or leaves hard water, start with diagnosis.

A private well near Alleman needs a plan for that property. Bring the latest laboratory results for bacteria, nitrate and other concerns; we add hardness, iron, TDS and nitrate screening and assess pump flow, pressure and sediment. Treatment may combine softening, iron or sulfur treatment, sediment filtration and a suitable drinking-water RO system. A neighboring city’s report cannot describe an individual well. Polk County Environmental Health offers private-well testing for coliform, E. coli, nitrate, arsenic and manganese. Confirm eligibility and scheduling with the county. For a nitrate or other specific drinking-water concern in Alleman, we start with a current certified lab result and plan treatment from it. For nitrate, that lab test covers nitrate and arsenic, and we choose the system from the results and test again after installation. The free home screening measures hardness, iron, total dissolved solids and a nitrate screening reading. Additional laboratory testing is chosen for the concern.
Recent results have been low. Since 2016 the state has 12 nitrate tests from 7 private wells in the township around Alleman, and the highest was 1.0 mg/L. One older test, from 2002, reached 10 mg/L. A yearly test of your own well is still the best guide, and it is free through Polk County.
On July 1, 2007. Alleman’s own water system, with city wells and a small plant, closed on June 29, 2007. Since then Des Moines Water Works has provided full water service to the city, and it also bills Alleman’s garbage and recycling.
It is softened at the plant, but not all the way. Des Moines Water Works aims to keep hardness under 150 mg/L, about 8.8 grains per gallon. The U.S. Geological Survey calls 121 to 180 mg/L hard. A quick test at your tap shows where your home lands.
Published options: $2,500 softener plus carbon; $2,850 softener plus carbon with tank RO; $897 tank RO; $997 tankless RO. Standard equipment installation and taxes are included. Confirm any additional plumbing, travel and the selected system’s written warranty before booking.
Alleman’s records were reviewed on October 4, 2026, for both city water and nearby private wells. Utility goals and township well tests are not a reading from your home. Sample dates appear with the test results.
