Ethnic Communities' Council of NSW Inc.
Saving Water in Asian Style Cooking Restaurants
Restaurant owners have been encouraged to become more water efficient by replacing one of the biggest water guzzling appliances in the commercial kitchen - the wok stove. Traditional wok stoves in Asian-style restaurants account for more than four billion litres of water a year in Sydney alone. Water jets clean and cool the woks and for speed and ease of operations are often left running all day. The Ethnic Communities Council has developed a multi-lingual education program to promote the economic and environmental benefits of water efficiency in business and encourage restaurateurs to switch to new 'waterless' wok stoves. The waterless wok is an innovative new fixture which can save up to 5,500 litres of water per stove per day and this project is saving 65.8 million litres of water a year.
Ethnic Communities' Council of NSW Inc.
Saving Water in Asian Restaurants Project Stage 2
The Ethnic Communities Council 'waterless wok' program has been so successful in Chinese restaurants that it has been expanded to Vietnamese and Thai restaurants. In Sydney, traditional wok stoves account for more than four billion litres of water a year. Water jets clean and cool the woks and for speed and ease of operations are often left running all day. The 'waterless wok' stove was developed with support from Sydney Water and can save up to 5,500 litres of water per stove per day. Stage 2 expanded the project into the Vietnamese and Thai restaurant community and provided the opportunity for additional Chinese restaurants to join the program. The project is saving 96.7 million litres of drinking water a year.

University of Western Sydney
Smart Irrigation Technologies for Saving Potable Water on Vegetable Farms
Vegetable growers in the Hawkesbury district have reduced their water use with the introduction of innovative irrigation technology on their farms. Farms in the Sydney area currently use an estimated 22,000 megalitres of potable water a year. The project installed two types of irrigation systems on eight farms. Field tests of the Kapillary Irrigation Sub-Surface System (KISS) showed it could reduce water use by 60% through underground watering of the plants' root system and reduced water loss through evaporation or run-off. Trials of the Irrigation Water Recycling System (IRWS), developed by the NSW Department of Primary Industries, showed it can reduce water use by half and reduce sediment and nutrients run-off to the Hawkesbury-Nepean River. The project was run by the University of Western Sydney in partnership with the NSW Department of Primary Industries and involved identifying eight farms to achieve the maximum savings, installing the systems and monitoring and analysing results to share with other growers. This is saving 3.7 million litres of water a year.
URS Australia Pty Ltd
Generating Potable Water Savings across 40 'City of Sydney' Irrigated Landscapes
New studies fine-tuning the watering needs of landscaped gardens have been put into practice at 40 City of Sydney parks, saving 50.6 million litres of drinking water a year. Developed by URS and Sydney Water, the Landscape Assessment Method identified exactly how much water was needed for irrigation based on foot-traffic, microclimate and soil type. The method has been successfully trialled at parks, ovals, golf courses and gardens at Ku-ring-gai and Auburn with funding support from rounds 1 and 2 of the Water Savings Fund. It was shown at Ku-ring-gai that many facilities were being over watered by as much as 12 million litres a year. Working with City of Sydney Council parks and management staff, this project identified ideal watering frequencies for most of the City's open spaces, including Observatory Hill, Sydney Park and Victoria Park. Many are high water-use facilities identified in the City of Sydney Council's Water Savings Action Plan. The data can also be used to accurately determine the feasibility and design of alternative water schemes such as stormwater harvesting or sewer mining for these landscapes.
Reducing Potable Water use on Golf Courses and Parks
New studies on the evaporation rates of water on different landscapes have been used to introduce new watering regimes at golf clubs in the Ku-ring-gai local government area. The project was led by URS Australia and involved assessing the water requirements of different parts of golf courses, based on their soil, microclimate and foot-traffic. The project built on the Sydney Water Landscape Assessment program which showed initial water savings of up 80% could be made. URS worked with the groundskeepers at the clubs and Ku-ring-gai Council to recommend changes in watering frequencies, irrigation and maintenance based on specific environments. As well as saving 13.3 million litres of water a year, this project has reduced nutrient run-off, improved overall soil moisture levels and might be expanded to other parks and sporting ovals in Ku-ring-gai.
URS Australia Pty Ltd
Water Savings at Auburn Botanic Gardens and Rosnay Golf Course
New discoveries about the irrigation needs of public spaces have been put into practice at Auburn Botanic Gardens and the Rosnay Golf Course. The project has built on research undertaken by URS and Sydney Water through the Landscape Assessment Program which allowed for the differences in microclimate, soil and foot traffic to be taken into account to determine ideal watering needs. URS worked with grounds staff at the Botanic Gardens and the golf course to determine the microclimate conditions for each irrigation zone and recommended alterations to watering regimes to maximise efficiency. The project is saving 12.8 million litres of drinking water a year.
Wollondilly Shire Council
Water Savings at Wollondilly Pools
The Wollondilly Shire Council's Water Savings Action Plan identified unaccounted water use at Wollondilly Community Leisure Centre and significant opportunities for savings at Warragamba Pool. Wollondilly Council carried out detailed logging and sub metering of the two sites to identify the source of the water loss and take steps to fix it. The data also helped identify other water saving opportunities at the pools. The project is saving 4.6 million litres of water a year.
