As a sustainable and ecologically sensitive community, OneOneFive Hamilton Hill is responding to climate change with waterwise strategies suited to Southwest WA’s warm and dry climate and is recognised as a Platinum Waterwise development. These initiatives support WA’s goal for Boorloo (Perth) and Bindjareb (Peel) to be world-leading waterwise living by 2030.

To enable a waterwise approach to water management OneOneFive have the following approaches:

• Diversification of supply: mains water, rainwater and a community bore scheme
• Water efficiency measures and programs to reduce demand: Waterwise Incentive package, Waterwise landscaping, Waterwise smart metering program and more, see the Design Guidelines for more information, available on this page, in the resources section.
• On-site stormwater absorption: Through on-lot soakwells, inclusion of permeable surfaces such as gravel, surfaces in private and public landscapes, and vegetated roadside swales (depressed channel) to capture and infiltrate stormwater runoff.

As part of OneOneFive Hamilton Hill’s Waterwise approach a community bore is in use for household and communal green space use. This is a centrally managed non-potable (non-drinking) ) water supply scheme that supplies groundwater, supplying water for private gardens and irrigation for green public open space within the development. Groundwater is delivered via a third pipe network and can be monitored to ensure water is used efficiently.

They have many benefits including:

• Providing suitable water for irrigation to ease pressure on mains water supply.
• Reduced environmental impact (energy-efficient and less carbon emissions) compared to mains water supply.
• Replaces the need for individual household bores
• It can maximise water efficiency when implemented with water metering, efficient irrigation systems and waterwise landscape design
• Supports healthy urban green spaces and improves neighbourhood liveability.

More detail on the benefits of a community bore and a case study on the OneOneFive Hamilton Hills’ community bore can be found from pages 117-135 of the ‘Guide to Waterwise Developments’

Community Bore Infrastructure

The Community Bore system consists of:

• The bore headworks (pump, tank and control equipment),
• A pressurised distribution network,
• Public open space irrigation infrastructure (sprinklers and dripline); and
• Residential connections with water meters (purple meter).

If your residential irrigation system has no or low pressure, it could either be an issue with your irrigation system, or the OneOneFive Community Bore.

To determine where the problem is, there are a few things you can do first using the check list below:

If you think the issue is with the connection to the Community Bore (no/low water supply), then you can lodge a query with NewGround (contact details below).

NewGround is DevelopmentWAs nominated landscape contractor for queries related to the Community Bore connection issues.

If you encounter a leak or have an issue with your community bore pipework or see an irrigation leak in a park or public streetscape at OneOneFive, please use the following contact information.

• Current: DevelopmentWA and their contractor NewGround Water Services, will manage the bore headworks, pressurised distribution network and the residential bore meters
• Future: When the OneOneFive Hamilton Hill development is complete the Community Bore system be handed over to the City of Cockburn (the City) to manage.

An incentive for residents to monitor their water use to help them save water and money. It includes an dollar ($) amount for homeowners to include waterwise landscape and irrigation items, and residents can receive a FREE water use monitoring system to help save water by signing up for the Waterwise Smart Metering Program, using the link in the tile below.
