The cost of the irrigation system will depend on other factors, but a base cost is something that is workable so as not to get surprised with the actual cost later on. For a front irrigation installation, the cost would begin at $2100.00, and for a rear installation, such would usually start at $1300.00. For the repairs services of irrigation, the same would be around $90.00 for the first hour and $25.00 for the succeeding hours.
