We design bespoke installations from a zone-by-zone assessment of need: Mediterranean perennial beds on 2 L/h pressure-compensating drippers, hedges on 16 mm inline tubing, vegetable plots on micro-sprinklers, lawns on sectored pop-up rotors. Each zone runs off its own solenoid valve so run times and frequencies can be matched to the planting.
For control, we install Wi-Fi or Bluetooth programmers so the system can be shut down remotely when it rains, and we add rain sensors and soil-moisture sensors so watering only happens when the ground actually needs it. The network is fully buried below frost level, with isolation valves zone by zone and drain points for winterisation in November.
