Drip Irrigation in Del Rey, CA
Drip puts water at the roots instead of spraying it over leaves, walls and walkways. It suits beds, shrubs, trees and gardens, while lawns usually stay on spray heads or rotors. A drip zone needs a filter, a pressure regulator and the right emitters for each plant.
We install drip zones, convert spray zones in planting beds, and repair existing drip lines: clogged emitters, broken tubing, loose fittings and missing regulators.
Drip puts water at the roots in Del Rey beds and trees, with little lost to walls and walkways, and it runs on a short, steady schedule.
