One of our busiest suburbs for retic work

From a single broken station to a complete new system, our reticulation technicians service Thornlie and the neighbouring suburbs.

Many Thornlie properties run older reticulation that benefits from a service and a modern controller set to the current watering roster. Verge planting and reticulation rules sit with the City of Gosnells, while watering days come from the state-wide roster, not the council — worth checking both before any verge retic work. These alluvial loams hold moisture well but infiltrate slowly — lower-precipitation nozzles or drip and staged run times prevent puddling on the flats. Bore feasibility varies street by street on this soil profile. Where drilling isn't attractive, the savings come from controller programming, rain sensors and fixing the leaks and misting heads that waste scheme water. Roughly 775mm a year here (Gosnells City), with about 79% of it falling May-September — the long dry rest of the year is why controller programming and coverage checks pay for themselves. Our depot in Jandakot puts Thornlie about 9 km away, comfortably inside our everyday coverage.

Clay-loam soil: slow to soak, prone to runoff

Soil — Pinjarra Plain clay-loams. Fertile but heavy ground: winter waterlogging and summer surface sealing both happen here. Cycle-and-soak scheduling plus sensible zoning handles both.

Groundwater & bores. The aquifer is present but less uniformly accessible under this ground — get a local assessment before committing to a bore. Either way, a well-tuned system keeps watering inside the 2-day roster comfortably.

Rainfall — about 775mm a year. Averages about 775mm a year at the Gosnells City gauge with roughly 79% falling May-September — so the controller should step down through autumn and observe the 1 June - 31 August sprinkler switch-off.

Customer stories from Thornlie

Water hammer and a failing valve in Thornlie

Station 6 at this Thornlie home was running two solenoid valves, and one of them was failing, which starved the station of pressure. In November 2025 our technician located it electronically and replaced it outright. Under the paving, a 19 mm poly line had split; it was repaired and the paving put back. Three fittings had blown apart at the barb, damage that may have come from earlier water hammer, the pressure shock when water flowing through a pipe is stopped suddenly.

The job wasn't finished in one visit. The last four or five sprinklers on station 6 still needed diagnosing for crushed or blocked pipe, and stations 7 to 10 were still to be tested. Both were scoped as the next stage.

Local reticulation questions

Yes — we cover all of Thornlie for repairs and maintenance. Repairs aren't quoted — every system is different, so just call us and we'll book a technician to diagnose and fix it on the spot.

Book a reticulation repair→

Yes, no approval needed. Thornlie is in the City of Gosnells. Any reticulation, including water pipes and sprinklers are to be laid beneath the surface of the verge and must not protrude above the lawn or garden surface when not in use.

Verge rules by council→

A controller repair isn't quoted: book the visit and it's diagnosed and fixed on site. An upgrade, say to Wi-Fi, can be quoted without a visit: tell us if your controller is hardwired or plugs into a power point (a photo helps). If it needs an electrician, we arrange one. Controller work is one of the jobs we do most in Thornlie.
