West Allis is mostly served by city water, but pockets of older properties, certain commercial sites, and parcels along the south edge of the city still operate on private wells. For those owners, the well is not optional infrastructure. It is the water source, and Water Well Development is what keeps it producing the way it needs to. Herr Well Drilling has been a water well contractor across West Allis and the surrounding metro since the family business started in 1964, and we still take regular Water Well Development calls from properties where the private well remains the working water supply.

What West Allis Private Wells Need From Professional Service

Private wells in a primarily municipal city tend to either be very old or to serve specific purposes that the city water connection does not. Either situation calls for careful attention. Our Water Well Development services for West Allis include the following:



Each visit starts with the well itself and the records behind it.

Older West Allis Well Restoration

Many private wells still in service across West Allis were drilled in the mid-twentieth century. Casings, screens, and pumps from that era all benefit from professional evaluation and water well restoration when issues develop. We assess whether the well can be brought back to reliable performance and what that will take.

Commercial and Industrial Well Maintenance

Some West Allis commercial properties run dedicated wells for irrigation, cooling, or process water. Those wells need different attention than household wells, particularly around yield reliability and water quality stability. Our work on these accounts covers Yield Enhancement Techniques, pump testing, and routine inspection to keep the system supporting the operation.

Sediment and Iron Bacteria Treatment

Sediment buildup and iron bacteria growth are two of the most common issues on older West Allis wells. Both respond to professional treatment, and both are far easier to address before they become severe. Our Sediment Removal and well cleaning services handle the physical buildup, and we coordinate appropriate water quality testing and treatment recommendations when chemistry is part of the picture.

Pump System Diagnosis

A lot of what gets called a well problem in West Allis is actually a pump or pressure system issue. Diagnosing the actual source of trouble before recommending a well work prevents unnecessary expense and produces better results. Our pump testing isolates whether the issue is in the well, the pump, the pressure tank, or the controls.

Key Benefits

Investment in Water Well Development on a West Allis property typically pays back in


  • Reliable water supply on properties where the well is the only source
  • Cleaner water and less sediment passing through the system
  • Pump life extension from reduced wear
  • Lower frequency of emergency service calls
  • Documented well-condition for insurance and property records
  • Honest information about whether the well is worth continued investment


The math on private well maintenance in a mostly municipal city is straightforward. A well that fails leaves the property with no water until the issue is resolved, which is a worse situation than it would be on a property with multiple supply options.

Service Areas

Our service area covers West Allis and the surrounding communities of Greenfield, Hales Corners, Wauwatosa, Milwaukee, New Berlin, and Brookfield. We base out of Dousman and reach West Allis addresses through several direct routes.

Frequently Asked Questions

  • What signs mean my West Allis private well needs attention?

    The usual signals: pressure drops, sediment in fixtures, water tasting or smelling different, pump running more often or longer, or recovery rates that have slowed noticeably. Wells in West Allis that have not been professionally serviced in seven or more years should be assessed regardless.

  • Are private wells common in West Allis today?

    Less common than in unincorporated areas, but they exist. Older residential properties, certain commercial sites, and parcels in specific sections of the city still run on private wells. Most of those owners have very specific reasons for staying with the well rather than connecting to municipal supply.

  • Can a fifty-year-old West Allis well still be productive?

    Often yes, with appropriate water well restoration. We have brought wells of that age back into reliable service through screen work, sediment removal, and formation redevelopment. The honest assessment of whether continued service is the right call depends on casing condition and the cost of the restoration relative to a replacement well.

  • What is aquifer evaluation for a West Allis well?

    It is the work of measuring what the well is actually drawing from, what its productive capacity should be, and where it stands relative to that potential. The evaluation tells us what we are working with before any other recommendation gets made.

  • How long does water well development take on a West Allis property?

    Most residential projects run one to two days. The first day handles assessment and initial mechanical work. The second day, if needed, covers final testing and verification. Commercial and high-capacity wells can run longer depending on scope.

  • Will well work affect city water connections on a West Allis property with both?

    The work we do is on the private well, not the city water connection. Properties with both can switch supply to the city side during well development if the plumbing supports it. We coordinate with the homeowner on the specifics during scheduling.

  • Are there permitting requirements for well work in West Allis?

    Maintenance and development work that does not involve structural changes to the well typically does not require new permits. Work that involves deepening, partial replacement, or abandonment does require DNR permitting, which we handle as part of the project.

  • How long has Herr Well Drilling served West Allis?

    Since the company was founded in 1964. We have project history on West Allis wells going back decades, and we are still actively servicing properties in the city today.
