P.O.A

Please note: Prices are shown excluding GST (where applicable) and are in AUD$

‘Headworks’ is Watermatic’s way of making irrigation installations easier for landscapers and contractors. The headworks model is based on standard pricing for the supply and installation of more complicated components i.e. the backflow assembly, irrigation controller, solenoid valves, wiring and rain sensor - giving you certainty. We come and install the 'Headworks' components and your team install the components downstream of the solenoid valves, i.e. drip pipe, pop up sprinklers and micro sprays.

At quoting stage, you can have confidence knowing how much the irrigation is going to cost.

  • We have pricing for the most commonly used irrigation set-ups
  • We have included some rates for supply only of materials to assist you at quoting stage - just work out your garden and lawn areas and then apply the material rates, plus add your labour
  • You include the relevant pricing in your quote to your client
  • Simply order the Headworks Kit/s you need. If you require materials, give us a material list, or we can create a material list from your plan
  • We come to site and install the Headworks
  • Whilst we are on site we deliver the materials for downstream of the valves. Your team install those components and simply connect to the solenoid valves

Headworks gives you
-Standard Pricing - gives you certainty.
-Quick - we get in and out in half a day.
-Cost Effective – professional irrigation system for a smaller investment.
-Reduces Scheduling – by eliminating an irrigation contractor working between soil, planting or mulching activities.
