1. Water Availability & Regulatory Considerations

Water development in and around Burlington depends heavily on parcel location.

Municipal vs. Private Wells

Many properties within Burlington city limits are required to connect to city water if service is reasonably available. Private wells are more common on:

• Agricultural land outside city limits

• Large rural parcels

• Irrigation-specific installations
   

We evaluate whether municipal connection is required before pursuing private well permitting.

Basin & Mitigation Considerations

​

Rural properties in the Skagit River Basin may be subject to water availability and mitigation requirements depending on location and development plans.

If applicable, property owners may need to:

• Secure documentation demonstrating legal water availability

• Install approved water meters

• Comply with usage terms outlined in mitigation agreements
   

Not all Burlington-area parcels fall within mitigation zones. Requirements are site-specific.

72-Hour Notice of Intent

​

All new well construction in Washington requires filing a Notice of Intent (NOI) with the Department of Ecology at least 72 hours before drilling begins. We handle this filing as part of our standard process.

2. Burlington Geology: River Gravel & Cobble Deposits

Burlington is dominated by unconsolidated Skagit River deposits — thick layers of sand, gravel, and large river cobbles.

High-Yield Gravel Aquifers

These formations can produce substantial water volumes when properly constructed. Many wells in the Burlington vicinity yield:

• 25–75+ gallons per minute (GPM)

• In some cases, higher depending on formation thickness
   

Drilling Challenges in Cobble

​

Loose gravel and large stones create stability challenges during drilling. Without proper casing techniques, boreholes can collapse.

We use:

• Telescoping steel casing

• Controlled advancement techniques

• Proper gravel packing and screen sizing
   

to maintain borehole integrity and long-term performance.

3. Common Burlington Well Challenges

Borehole Collapse (“Cave-In” Risk)

Unconsolidated gravels naturally want to slump inward. Proper casing installation during drilling is critical to prevent collapse and ensure a straight, stable well.

​

Turbidity & Fine Sediment

​

High-flow wells can draw fine silts if improperly developed. We utilize thorough well development techniques, including air surging, to stabilize the aquifer around the screen before installing permanent pumping equipment.

​

Seasonal Water Table Fluctuations

​

Shallow groundwater levels in the floodplain may fluctuate seasonally in response to river conditions. Deeper screened wells often provide more consistent year-round production.

4. Water Quality Considerations in Burlington

Iron & Manganese

​

Floodplain gravel aquifers commonly contain iron and manganese, which can cause orange or dark staining. Filtration systems can effectively address these issues.

Nitrates in Agricultural Areas

​

Because Burlington is surrounded by farmland, periodic nitrate testing is recommended for private well owners.

​

Hard Water

​

Calcium and magnesium may contribute to hardness. Water softening systems can help protect plumbing and appliances.

​

5. Typical Depths & Performance Benchmarks

While every parcel is unique, common Burlington-area well characteristics include:

• Typical Depth: 100–160 feet

• Shallow Groundwater Encountered: Often 20–40 feet (not typically used as final completion zone)

• Static Water Level: Frequently 15–40 feet below surface

• Yield Potential: Many wells produce 25–75+ GPM
   

Well design focuses on sustainable production rather than maximum short-term yield.
