How Long Does it Take to Construct a New Well System?
Constructing a new well system is a major investment for Colorado homeowners, businesses, and rural properties that rely on private groundwater. While timelines vary based on site conditions and system complexity, most residential projects follow two main phases: drilling the well and installing the complete water system.
GeoWater Services provides professional well construction throughout Colorado mountain communities, the Denver Metro Area, and the Front Range. Here’s what affects your project timeline and what to expect during each stage.
Two Phases of Well Construction
Phase 1: Drilling the Well
The first phase involves drilling to access a reliable groundwater source. The duration depends largely on:
- Required well depth
- Local geology (rock, clay, sand, fractured formations)
- Drilling method used
Residential wells in Colorado commonly range from less than 100 feet to 500 feet or deeper, depending on groundwater availability.
Drilling can take several hours to multiple days, particularly in mountainous or rocky terrain. Depending on site conditions, contractors may use:
- Rotary drilling
- Cable tool drilling
- Down-the-hole hammer drilling
- Reverse circulation drilling
The drilling method is selected based on site geology, efficiency, and safety.
Phase 2: System Construction & Installation
Once the borehole is completed and properly cased, the next phase involves building out the full water system. This typically includes:
- Installing the submersible pump
- Running associated wiring and electrical components
- Connecting the water distribution line from the well to the home
- Installing the pressure tank
- Adding water storage tanks (if required)
- Installing water treatment equipment (if necessary)
Pump and pressure tank installation is typically straightforward. However, the time required for installing the water distribution line depends on the distance between the well and the structure.
If additional storage is required, extra time may be needed to place and equip tanks.
Not every well requires water treatment. Some groundwater sources are naturally clean and safe. Others may require one or multiple treatment technologies depending on the presence of minerals, bacteria, sediment, or other contaminants. Treatment needs are determined through professional water quality testing.
Additional Factors That Impact the Timeline
1. Permitting
Colorado requires proper permits before drilling begins. Approval times vary by county and project type, ranging from a few days to several weeks. Experienced contractors help streamline this process.
2. Site Evaluation & Preparation
A professional site evaluation ensures the well location meets setback requirements and minimizes contamination risks. Preparation may include improving access for drilling equipment.
3. Testing & Final Inspection
After installation, the system is tested to verify pump performance, pressure levels, and water quality compliance. Laboratory water testing may add one to two days to the process.
Estimated Timeline for a New Well System
For most residential projects, the full well construction process takes approximately 7 to 14 days from drilling through final system testing. More complex projects — such as deeper wells, long distribution lines, or advanced water treatment systems — may extend the timeline.
Frequently Asked Questions
How deep does a residential well need to be?
In Colorado, most residential wells range between 100 and 500 feet deep. The exact depth depends on groundwater availability and local geological conditions.
Do all wells require water treatment?
Not necessarily. Some groundwater sources meet quality standards without treatment. Others may require filtration, disinfection, softening, or multiple treatment technologies depending on water test results.
How long does drilling alone take?
Drilling may take only a few hours for shallow wells or several days for deeper wells or sites with challenging geology.
