K2 Sustainable Housing Project: Water Usage Reduction and Design

The K2 Sustainable Housing Project, funded by the government of Victoria, aimed to achieve environmentally sound design and performance with minimal consumption of non-renewable energy sources. This project involved four buildings with 96 apartments, aiming to reduce mains electricity, gas, and water consumption. The project implemented the Aquacell G10 greywater recycling system, collecting greywater from showers and hand basins to be reused for toilet flushing and irrigation. The project's goal was to reduce water consumption by 53% compared to standard apartments. The project installed water-efficient appliances and rainwater harvesting to further reduce water usage. The project highlights the importance of sustainable design in residential projects, showcasing the practical implementation of water conservation strategies, and the benefits of such initiatives to the residents.

K2 Sustainable Housing Project
The main aim of the housing project was to reduce mains usage of water.
K2 is a social housing project funded by the government of Victoria to achieve
environmentally sound design and performance with minimal consumption of non-renewable
sources of energy. The K2 project entails four buildings with 96 apartments of residential. The
building was committed to achieving the following listed goals
 A lifespan of 200 years
 The efficient ability of renewable energy generation on the site.
 Minimal or complete non-consumption of renewable sources of energy
 Halve the average use of water in the town.
The objectives were outlined for all the 96 apartments to consume: a mains electricity of
55 percent less, a mains gas of 46 percent less and a mains water of 53 percent less inclusive of
water for irrigation in comparison to a normal standard apartment on a year basis (Azhar, 2011).
The Aquacell G10 in action
With an aim of achieving the goal of reduction of mains usage of water for the
household, the G10 greywater system of recycling was installed by Aquacell. Showers and hand
basins of the apartments form the collection source of greywater located at the floors of K2
buildings and after Aquacell treatment of the water, it is then reused for flushing of toilets and
irrigation purposes.

Benefits of the project to Residents
The estimation of averaged water consumed at Melbourne, hosting city of the project, for
home use is 650 litres daily. In order to attain project desired goal of water consumption, water
efficient appliances devices for saving water were erected including rainwater catchment and
greywater recycling which eventually facilitated a reduction in daily consumed water(Szokolay,
2014).
