How Much Does a Dry Well Installation Cost? [2026 Data]

In 2026, the national average cost of dry well installation is $3,110, based on 1,339 verified projects from Angi Pros. Most homeowners pay between $1,334 and $5,139, with the spread driven by well type, yard size, and local labor rates. Concrete systems can reach up to $10,300, while a percolation test adds $150 to $1,000 before installation even begins.

Dry Well Installation Cost Factors: What Determines the Price?

Several variables shape the final price of a dry well installation, including type, water volume, soil absorption rate, and labor. Understanding each factor before you get quotes helps you evaluate bids accurately and avoid surprises.

Dry Well Type

Dry well costs range from $50 for a basic gravel system to $4,500 or more for a large concrete installation. Gravel systems are the most affordable and suit most standard residential drainage needs, while prefabricated plastic systems offer a mid-range option with easier installation than concrete systems. Concrete systems are the most advanced and expensive, requiring heavy machinery and professional installation, but hold significantly greater water volume.

The table below compares average costs across three dry well types:

Dry Well Size

The volume of water your dry well needs to handle—determined by your lawn's square footage—directly sets the system size and cost. Each square foot of lawn requires 0.623 gallons of water per week, and any excess is routed through drainage pipes. Here is how dry well costs scale by capacity:

Consult a local well pump contractor to size your system accurately—they will assess soil absorption rate, lawn type, square footage, irrigation habits, and annual rainfall before making a recommendation.

Labor

Labor for dry well installation runs $50 to $100 per hour, with the final bill varying based on the type and size of system being installed. Most contractors provide a project quote upfront that bundles labor, materials, and equipment costs. For complex or large systems, expect the labor portion to represent a significant share of the total project cost.

Location

Your location determines your soil composition, which controls how quickly water absorbs into the ground and affects how many wells your yard requires. Slow-absorbing soil requires more wells to give the ground adequate time to process runoff, which raises both material and labor costs. A contractor can measure your soil's absorption rate through a percolation test before sizing your system.

Prep

A percolation test is an essential first step before installing a dry well, measuring how well your soil absorbs water so the system can be sized correctly. Depending on the number and size of test holes required, the evaluation costs between $100 and $1,000. Some contractors include this test in their overall installation quote, so ask about it when comparing bids.

Dry Well Ongoing Costs: What to Budget For Later

Owning a dry well comes with ongoing maintenance and operating expenses that should be factored into your total budget from the start. Knowing these costs upfront helps you avoid surprises and plan for the long-term performance of your system.

Dry Well Maintenance

Dry wells require regular maintenance to prevent clogs and obstructions caused by debris and runoff buildup. You can handle basic upkeep yourself by removing debris, checking for standing water, and performing routine cleanings. If you prefer to hire a professional, maintenance services typically cost $45 to $150 per hour.

Dry Well Operating Costs 

Depending on your location, a permit may be required before installing a dry well, and that cost can range from $25 to $50. Permits typically need to be renewed every five years, so factor that recurring expense into your long-term ownership budget.

DIY Dry Well Installation vs. Hiring a Pro

Doing a dry well installation by yourself is a cost-effective option for homeowners who don’t need an advanced or large system. DIY installations are often only recommended for gravel or plastic containers, as concrete containers require the use of heavy equipment. Even with DIY installations, it’s still recommended to have a contractor conduct an assessment of your yard to help determine the volume of the dry well you need. 

Completing the installation yourself will require a shovel, gravel, plastic container, and accessories, costing you between $185 and $385. Plus, the physical labor and elbow grease needed to dig a large enough pit can be tiring. 

If you feel uneasy about the physical requirements, consider hiring a contractor to save yourself some stress. Professional dry well contractors know how to do the job quickly and efficiently so you won’t have to worry about future water damage or improper installation fixes.
