Other factors that affect cost
Other than garden or lawn size, here are the other factors that go into pricing for drip irrigation:
Type of system
Drip irrigation system costs depend on the type of system you choose. Please see the average prices by system type below.
|System type||Typical Cost|
|Above-ground||$225 – $2,000 / water zone|
|Subsurface||$815 – $4,335 / acre|
|Sprinkler conversion||$300 – $1,200 / water zone|
|Foundation drip||$1.50 – $4.75 / linear foot|
Above-ground vs. subsurface irrigation:
- Above-ground (i.e. surface irrigation) drip systems work well for residential vegetable gardens and raised beds. Expect to pay $223 – $2,000 per watering zone.
- Subsurface drip irrigation systems are best for lawns and large areas of crops. Expect to pay about $815 – $4,335 per acre for in-ground drip irrigation.
- You can convert water zones of in-ground sprinkler systems to drip irrigation zones.
- Expect to pay $300 – $1,200 per irrigation zone for a sprinkler conversion.
Foundation drip irrigation:
- Foundation drip systems typically cost $1.50 – $4.75 per linear foot.
- In dry climates, foundation drip systems are used to moisten clay soil and keep it from expanding and contracting.
Most homeowners install drip irrigation in one watering zone. However, if you are connecting multiple zones to a drip irrigation system, expect to pay an additional $250 – $775 per zone.
How many water zones do I need? A watering zone is a section of your yard that gets its water supply from the same valve. Additional zones are needed because of water pressure restrictions and differences in watering needs. To estimate the number of water zones in your garden, consider the following:
- How much water pressure can you use at once?
- What is the water flow rate of the system’s emitters?
- Can you adjust the flow rate of separate emitters?
- How long is the drip line?
Quality of parts
Higher-quality parts typically cost more, so expect to pay a higher upfront cost for high-quality drip irrigation systems. However, higher-quality parts last longer and require fewer repairs. Please see the typical cost of drip irrigation system components in the table below.
|Adapter||$3.50 – $9.50|
|Backflow preventer||$4 – $6.50|
|Connector||$4.50 – $13.50|
|Drip tubing||$15 – $40|
|Drippers / emitters (10 pack)||$5 – $10|
|Mainline distribution tubing (100 ft.)||$13 – $45|
|Pressure regulator||$7 – $20|
|Sensors||$20 – $150|
|Tubing end cap||$1 – $3.50|
|Valve||$4 – $60|
What do the components of a drip irrigation system do?
- Adapter fittings convert pipe thread to hose thread fittings, which is essential for your system’s efficiency.
- Backflow preventers ensure water only passes through the system in one direction, preventing the contamination of clean water.
- Drip tubing is made out of polyethylene, and it is responsible for getting water to the vegetation.
- Drip tape dispenses water in some surface drip irrigation systems.
- Drippers/emitters control the amount of water dispensed to the plant roots and the water’s flow rate.
- Mainline distribution tubing works with pumps to circulate water through the system.
- Pressure regulators reduce water pressure so the system can dispense a slow and steady water flow.
- Rain or moisture sensors conserve water and protect your garden from over-watering.
- Valves turn the water on and off. Many valves are attached to a timer that automates the system.
Type of vegetation
The type of plants you water affects the drip irrigation system’s cost, as well. For example:
- Plants with specialized water needs may require an additional water zone, thus increasing the cost by $250 – $775 per zone.
- Lawns thrive with subsurface drip irrigation systems, which cost more than above-ground systems. Subsurface systems typically cost $815 – $4,335 per acre, and additional expenses may apply for land preparation.
- Agricultural systems typically cost more than residential systems. Sophisticated systems for professional use can cost over $3,000 per acre.

Cost of drip irrigation installation by location
Drip irrigation system prices vary by location for the following reasons:
- Tax incentives and rebates are offered to homeowners in some locations when they upgrade to a water-efficient irrigation system, such as drip irrigation.
- Operational costs vary depending on the cost of the water source. For example, most residential irrigation systems connect to city water, and that cost varies from city to city.
- Clay and rock soils lead to higher labor costs when installing a subsurface system.
- Labor costs vary by location. Homeowners living in cities with a high cost of living should expect to pay more than average for labor.
The biggest downside to drip irrigation systems is that they clog easily. According to a study by the International Journal of Current Microbiology and Applied Sciences, low water quality is the leading cause of clogging. When water has impurities such as particles of sentiment, chemicals, and micro-organisms, it becomes prone to clogging drip irrigation systems.
Drip irrigation systems are worth it to most homeowners because:
• Reduced water bill: Drip irrigation gets water right to the plan’s roots, reducing evaporation.
• Low upfront cost: The average professionally installed drip irrigation system is under $500, and you can purchase a DIY kit for under $50.
• Great for gardens: Less water gets on leaves and fruit, and excess moisture can sometimes cause disease.
• Fewer weeds: Because drip irrigation targets the root zone, weeds have less access to water.
A low-cost alternative to drip irrigation is a soaker hose, which can be purchased for as little as $10. A soaker hose is like a garden hose with thousands of tiny holes for dispensing low-pressure water. They are easy to use but less water-efficient than a drip irrigation system because you can’t adjust the water pressure.
Drip irrigation can help you maintain a healthy, high-yield, low-cost garden. You can build a drip system for $25 – $200 or leave it to the professionals. An irrigation specialist will ensure the system is efficient and effective, so contact a pro near you for the best results.
