Urban Growth NSW have recently developed an assisted living facility, designed to relocate individuals in disabled care homes to a purpose-built facility, in order to better their care.
The facility was zoned for development in a non-sewered area in Llandilo, NSW. The option of connecting to sewer was evaluated and deemed infeasible, due to the distance from existing sewer infrastructure and the associated cost of connection.
Given the small scale of the site and its relatively low-lying topography, it was necessary to install an Aquacell S10 membrane bioreactor (MBR) based system. The S10 MBR provided an option for treating onsite wastewater to produce high-quality water onsite disposal. To reduce the irrigation area required, the treated water from the MBR has been designed for sub-surface irrigation on the site.
No treated water is permitted to run off the property, so Aquacell worked with the project team to deliver a scheme that could safely contain the wastewater away from residents. The wastewater is treated in the MBR, and the treated water is used to provide sub-surface irrigation for green spaces on the property. The site is in a dry-climate zone, and as a result, the treated wastewater provides a sewage treatment facility and a non-potable irrigation source in one.
The development was completed in December of 2017, after
the stewardship of Aquacell’s operations team ensured the system successfully met the performance requirements under the scheme.
This is a great example of how a feasible development solution can be devised for landholders with limited space and no sewer.
