"Our lawn was looking very sad due to bad and broken retic. Lots of broken sprinklers replaced and some troubleshooting and our lawn looks amazing. Thanks John and Perth Retic!"

Our nearest retic work is next door
Repairs aren't quoted — you book a repair and our technician diagnoses and fixes on site, with the parts already on the van. New systems are quoted after a paid site assessment, credited in full to your install if you accept the quote within 30 days.
Postans is covered off the work immediately around it: 14 jobs in Bertram, 12 in Anketell and 16 in Mandogalup. Same technicians, same vans — a booking here joins an existing run rather than becoming a special trip.
Verge planting and reticulation rules sit with the City of Kwinana, while watering days come from the Water Corporation sprinkler roster, not the council — worth checking both before any verge retic work. Our depot in Jandakot puts Postans about 14 km away, comfortably inside our everyday coverage.

Sand over limestone: what it means for your retic
Soil — Spearwood sands. Classic Spearwood profile: free-draining sand, limestone beneath. Lawns respond best to two shorter cycles inside the same watering window (both before 9am, or both after 6pm), and sprinkler layouts need decent pressure to cover evenly.
Groundwater & bores. This suburb sits on Perth's sandy coastal plain over the superficial aquifer, where garden bores are common and generally productive. Bore water isn't metered like scheme supply, so a serviced bore slashes the cost of keeping gardens green — the standard 2-day roster and June-August sprinkler switch-off still apply.
Rainfall — about 750mm a year. Averages about 750mm a year at the Medina Research Centre gauge with roughly 77% falling May-September — so the controller should step down through autumn and observe the 1 June - 31 August sprinkler switch-off.

Local reticulation questions
Check with the City first. Postans is in the City of Kwinana. The sprinkler roster is a Water Corporation matter, so it doesn't change at the council boundary.
Generally yes — Postans sits over accessible groundwater, which is why garden bores are common here. What varies is depth, yield and how much iron comes up with the water — all worth checking on your block before committing. We install, service and repair bores and pumps.
Postans sits on Spearwood sands. Water moves through it fast, and the sand can turn water-repellent once it dries out. Your technician confirms the profile on site before programming anything — Postans blocks vary street to street.
Postans is about 14 km from our Jandakot depot and sits on a run our vehicles work weekly, so most repairs here are booked within days, not weeks. Repairs aren't quoted — you book a repair and the technician diagnoses and fixes on site, most faults in the same visit, with the parts already on the van.
Repairs aren't quoted: you book one, and the technician diagnoses and fixes it on site, most faults in the same visit. If parts need ordering, we tell you the cost first.
