Initial and long-term costs, efficiency and future maintenance levels are all major
factors in determining what types of irrigation systems are appropriate for your
Narrow Planters (1’-7’):
Bubblers and spray are simpler to maintain but more likely to wet pavement or create
a tripping hazard. Bubblers are not suitable for sloping ground or turf.
Probably the most qualified bidder. Regular oversight from a knowledgeable representative
of the Owner.
Not necessarily the low bidder. Oversight from a representative of the Owner.
Probably the low bidder. The maintenance company will determine methods and operations
unless there are complaints.
Medium Planters (8’-19’):
Spray irrigation is a more cost-effective alternative in medium width planters, although
its efficiency is not comparable to drip or bubblers.
Bubblers should be installed 2’-4’ apart for adequate coverage (creating a cluttered
appearance) but can be appropriate where maintenance will be very poor.
Large Planters (20’+):
Drip is comparatively expensive, but still a realistic option for its efficiency.
Bubblers and spray are rarely used in large areas.
