Perth Cultural Centre

Perth Theatre Trust

Irrigation & Smart Water Management Technology

Project Scope

Perth Cultural Centre is located in Northbridge where it is the junction between the Western Australian Museum, the Art Gallery of WA and the State Theatre. 

We have worked with the State Theatre Trust since 2009, when we installed the irrigation systems at The Urban Orchard, designed by Landscape Architect Josh Byrne.

The most recent changes have been towards the Museum where Deep Green Landscaping has redesigned the front greenery in front of the Museum’s entry.

The Perth Culture Centre is large and spread out, creating some interesting challenges. The public nature of the site presented issues that residential irrigation systems don’t face such as vandalism/theft of sprinkler heads and public events with heavy foot traffic on lawns.

Over the last 24 months we have updated the underlying irrigation system that waters all garden beds and lawns and introduced a smart water controller for improved water management.

Site Parameters

The public space in the Cultural Centre is complex because it is owned by the Art Gallery, Museum and State Theatre. This introduced design and installation complexities that are rare on most commercial projects.

PlanningDocumentation & Safety is foremost a priority on commercial projects where there are many trades on site and communication is important.

We use a series of procedural documents including:

  • As Constructed Irrigation Schematics
  • Health & Safety Plan
  • Irrigation Station Mapping

Events & Usage

The Cultural Centre is used for public events like Fringe Festival, Comedy festivals and Christmas Pageants. Lawns cannot be damp and sprinklers cannot be run when these events are on.

Therefore our design solution include:

  • Flexible watering times
  • Low profile irrigation (out of sight and out of mind)

Smart Water Management

The Cultural Centre uses a smart water controller to quickly and easily manage water delivery across its numerous garden beds and lawns.

There are 19 zones each customised to the specific water needs of specific garden beds and lawns. This level of sophistication means water is used efficiently and the plants are healthier and stronger.

Seasonality is programmed into the smart controller by linking to nearby weather stations. The 19 zones use predictive adjustments based on localised weather conditions to ensure gardens are not over watered in winter and underwatered in summer.

Flexibilty is important and we are able to change watering times remotely so our water technicians do not need to visit the site each time a change needs to be made. This is cheaper for the Museum and makes our water management job easier.

Sprinklers

Sprinklers were used as little as possible across the Cultural Centre because they are impractical for the area.

Where they have been installed, we have used Hunter Industries MP Rotators in extra tall pop-up bodies. This means we can install the sprinklers well below the mulch hidden from the public and the tall pop shaft can rise above the mulch or lawn.

Hunter MP Rotators are one of the Waterwise Approved Sprinklers.

Subsurface Dripline

The 15 garden beds are irrigated using Netafim’s Uniram ASXR  subsurface drip line.

The dripline sits 100 millimetres below the soil surface where it is hidden from people and doesn’t evaporate with the warmth of the day. 

The driplines are spaced between 300mm and 450mm depending on the type of plants. All driplines are staked down every three meters and covered with mulch.

Netafim’s ASXR dripline has three important technologies that increase the sytems longevity and reliability.

  1. Copper oxide lines the inside of the drip and is a root deterrent that stops [plants from growing through holes and into dripline.
  2. The “anti-suck-back” feature prevents sand and soil from been sucked back into the dripper and dripline once that zone has stopped irrigating. This stops clogging
  3. Anti-siphon mechanism holds consistent water pressure throughout the system and prevents water from leaking when not irrigating.

    The anti-siphon feature was initially developed for the greenhouse industry where they irrigate for only one minute for upto 30 times per day.

    Before the anti-siphon diaphragm was invented the lower section of the greenhouse ended up with all the excess water and drained into the plants soil (media) causing very damp soils and fungal issues. Now with anti-siphon each dripper opens and shuts under pressure at the same instant throughout the length of the dripline providing 100% emission uniformity.
