About Well Water Treatment in Des Moines

Well water treatment encompasses the systems and methods used to remove contaminants, improve taste, and ensure safe drinking water from private wells. Unlike municipal water that is treated at a central facility, private well owners must install and maintain their own treatment equipment. Treatment needs vary dramatically by region and geology — a well in limestone country may need only a water softener, while a well near agricultural land may require nitrate removal, iron filtration, and UV disinfection. Common treatment technologies include sediment filters for particulates, activated carbon for taste and organic chemicals, water softeners for hardness and iron, reverse osmosis for heavy metals and dissolved solids, UV sterilization for bacteria and viruses, and chemical injection systems for severe iron or sulfur problems. The right treatment system depends entirely on your water test results — never install treatment equipment without first testing to identify what contaminants are present and at what levels. Over-treating is wasteful and under-treating is dangerous. A qualified water treatment professional will review your lab results, recommend appropriate equipment, and size the system for your household water demand and flow rate.

What Des Moines Homeowners Should Know

Local Soil Conditions: Polk County soils are dominated by deep Mollisols developed on the Des Moines Lobe — the youngest glaciated region of Iowa, covered by ice as recently as 12,000-14,000 years ago. Webster silty clay loam and Nicollet clay loam are the most common soils — both poorly to somewhat poorly drained with seasonal water tables at 0-24 inches, 30-45% clay content, and slow to moderately slow permeability. Clarion loam on upland swells is better drained with moderate permeability. Harps silty clay loam in closed depressions is very poorly drained with water at the surface much of the year. Des Moines River floodplain soils (Nodaway silt loam, Haynie fine sandy loam) are deep and moderately well-drained but subject to annual flooding.

Water Table: Webster and Nicollet soils have seasonal high water tables at 0-18 inches from December through May. Clarion soils have water tables at 18-36 inches. Harps soils have water tables at or above the surface. Polk County's extensive subsurface tile drainage infrastructure has lowered average water tables in agricultural areas by 1-2 feet but the tiles themselves intercept and concentrate lateral flow. The Raccoon River and Des Moines River maintain water tables within 3-5 feet along their corridors.

Climate Impact: Des Moines has a humid continental climate with hot, humid summers (average July high 85°F) and cold winters. Annual precipitation averages 35 inches, distributed through the year with spring peaks. Severe thunderstorms and occasional tornadoes in spring and summer can deliver intense rainfall. Winter precipitation is primarily snow and mixed precipitation (20-25 inches). Spring flooding of the Des Moines and Raccoon Rivers is a recurring event, with the 2008 floods being among the most destructive in Iowa history.

Signs You Need Well Water Treatment

  • Water test results show contaminants exceeding EPA guidelines
  • Hard water causing scale buildup on fixtures and appliances
  • Iron or manganese staining on sinks, toilets, and laundry
  • Rotten egg smell indicating hydrogen sulfide in the water
  • Cloudy or discolored water despite a properly functioning well
  • Acidic water (low pH) corroding plumbing and causing blue-green stains

The Well Water Treatment Process

  1. 1 Get a comprehensive water test to identify specific contaminants and their levels
  2. 2 Consult with a water treatment professional to review test results and recommend solutions
  3. 3 Select the appropriate treatment system sized for your household water demand
  4. 4 Professional installation of treatment equipment at the point of entry or point of use
  5. 5 Initial water test after installation to confirm contaminants are being removed effectively
  6. 6 Establish a maintenance schedule for filter replacements, salt refills, and annual retesting

Frequently Asked Questions — Des Moines

Does my Des Moines area septic system contribute to the Raccoon River nitrate problem?
Individual residential septic systems contribute a very small amount of nitrate relative to agricultural drainage, which is the dominant source. However, the cumulative effect of many on-site systems in the Raccoon River watershed is measurable and is part of Iowa DNR's watershed management planning. Properly functioning systems with adequate soil treatment substantially reduce nitrate loading compared to failing systems. Maintaining your system — pumping on schedule, fixing leaks, reducing household water use — is the most effective thing you can do to minimize your system's contribution to watershed nutrient loading.
What is a mound septic system and why do I need one in Polk County?
A mound system builds the drainfield above the native soil on an elevated bed of imported sand and gravel fill, achieving the required vertical separation from the seasonal water table or restrictive soil layer. Iowa DNR requires a minimum 2-foot separation between the drainfield bottom and the seasonal high water table for most system types. On Webster silty clay loam — which dominates most of Polk County — the water table is within 12-18 inches of the surface, leaving no room for a below-grade drainfield. Mound systems solve this by elevating the drainfield 2-4 feet above the native soil. They cost $10,000-$17,000 in the Des Moines area, reflecting material costs for imported fill sand and gravel.
How often should I pump my septic tank in the Des Moines, Iowa area?
Iowa DNR recommends pumping every 3-5 years. In Polk County, a 3-year cycle is advisable for the majority of systems, which are mound or LPP types serving the poorly drained soils of the Des Moines Lobe. Annual inspection of pump and float components is recommended for all pump-dependent systems (mound, LPP). If your household includes more people than the system was designed for, or if you have a garbage disposal (which significantly increases solids loading), pump every 2-3 years.
How much does septic pumping cost in the Des Moines, Iowa area?
Septic pumping in Polk County typically runs $225 to $375 for a standard residential tank. Iowa's moderate cost of living makes pumping costs lower than the national average. The Des Moines metro area has numerous licensed septage haulers, maintaining competitive pricing. Many Polk County pumpers offer a combined pump-out and visual inspection for $275-$400 that allows early detection of mechanical or structural issues.
My Polk County property floods occasionally — what does that mean for my septic system?
Flood events can overwhelm and damage on-site systems. If your system was submerged or received large volumes of floodwater, Iowa DNR guidance recommends pumping the tank, inspecting all components, and avoiding heavy system use until the ground has drained. Floodwater introduces sediment and pathogens into the tank and drainfield, and the saturated soil after a flood reduces drainfield capacity temporarily. For recurring flood risk, speak with your county health department about whether your system can be modified to reduce flood vulnerability, or whether relocation of components to higher ground is feasible.
