The average cost of a new irrigation system is approximately $2,450, as of 2015, according to HomeAdvisor.com. Homeowners spend an average of roughly $1,800 to $3,300 in total.
Prices vary depending upon the type of system installed. Although irrigation and sprinkler systems are interchangeable in terms of their primary functions, LandscapingNetwork.com distinguishes a drip irrigation system from a sprinkler system according to the reduced amount of labor a drip irrigation system requires.
LandscapingNetwork.com estimates the cost of a drip irrigation system at about $300 per zone when there is an existing sprinkler system. The price per zone increases roughly $400 per zone for an average drip system with varied planting. For homeowners with no existing systems, the term "irrigation system" simply implies a sprinkler.
