Subsurface Irrigation
From CATI Publication #940401

| CIT has been awarded a contract to renovate portions of
the campus irrigation system for CSU, Fresno. Part of that project
will include the installation of subsurface systems for lawn
irrigation. Grounds administrators initially planned to have the irrigation system designed and installed by an outside contractor. However, with the tight budget situation, they decided to consider whether the system could be installed using the university’s own resources, such as CIT. The university already had plans for an irrigation system and asked CIT to review the plans and give them a bid on installing the system. The original plans called for sprinkler irrigation for the entire campus. Upon reviewing the plans, however, CIT and grounds supervisors decided that some of the areas could be better irrigated with subsurface irrigation. This decision was based on CIT’s considerable experience testing subsurface irrigation on test plots for the last five years. The initial phase of the plan calls for renovating seven acres on campus. Much of that will be irrigated with the subsurface drip, using approximately 70,000 feet of drip tubing. There are hundreds of trees on the CSU, Fresno campus and in some areas, installing drip irrigation will be impractical because of the roots. Those areas will be irrigated with pop- up sprayheads and rotor sprinklers. CSU, Fresno is the first campus to utilize its own staff and students in a major capital outlay project such as this. Many bureaucratic obstacles had to be overcome; however, the end result will allow the university to obtain a state-of-the-art irrigation system for substantially less money than it would have cost had outside contractors been used. This project also will provide a tremendous opportunity for students to gain experience in installing irrigation systems, especially in installing subsurface systems. The project is expected to be completed this spring.
