Graph 3.2 Indicative distribution of water usage at Palm Beach Golf Course Palm Beach Golf Course is ranked second in terms of Councils highest water usage for 2004/2005, equivalent to a usage of 0.2kL/m2/annum. Whilst no benchmarks are
available, it is found to be approximately comparable to the lower end of the Sydney Water benchmark for water usage on reserves and parks (0.2 to 0.4 kL/m2/annum). The current reduced irrigation regime has been of ongoing concern to Palm Beach Golf Club, who has investigated various options over several years to reduce potable water consumption. These investigations include: groundwater extraction attempts at deep boring have only found highly saline groundwater, unsuitable for irrigation sewer mining insufficient sewage supply has not made this option viable desalination the high initial and ongoing costs were not considered to be feasible transportation of recycled effluent from Warriewood Sewage Treatment Plant concerns were raised over the issues of high truck movements and site storage stormwater reuse this had limited scope because of the small contributing catchment, few drainage structures, and the difficulty in placing water storages on the site (due to a high water table and space requirements). Results of the technical audit have shown very little opportunity for alternative water supplies to the area to supply the golf course. However, improvements could be made to maintain efficient water usage at the course by: improving irrigation practices and increasing water conservation awareness of contractors and staff monitoring water meters through the purchase and installation of data loggers for flow monitoring and leak detection undertaking seasonal benchmarking and adjustment of the activation level of the rainfall sensor (if over-irrigation is detected). Course improvements to reduce water consumption include the replacement of existing grasses on the course with drought tolerant and salt resistant turf (suitable for limited irrigation by existing spear points on the course). Whilst not addressed by the technical audit, the changing of the existing sandy soil profile on the tees and fairways to a more water retentive soil profile also warrants further investigation. Council will encourage Palm Beach Golf Club to further investigate both options, and if viable, include the works on review of the capital works program. Since the audit, Palm Beach Golf Club has negotiated a new special permit for water use on the course with Sydney Water. The conditions of the permit are based on a volumetric limit of water usage of 1600kL/month (averaged at 52.7kL/d) on greens and tees using watering systems at specific times of day, and allowances for hand watering of fairways on specific days at set times. The permit also allows for restricted watering on greens on days when temperatures are projected to exceed 30 degrees. Palm Beach Golf Club also stated their commitment to undertaking improvement of irrigation practices, monitoring of water meters, seasonal benchmarking, and adjustment of the rainfall sensor (if required), as part of their application for the special permit.

A walk through technical audit was undertaken of the site by Council. Daily water usage over 2004/2005 was 20.5kL/d. The historical water usage over past years were 20.5kL/d in 2001/2002, 50.6kL/d in 2002/2003 and 40.0kL/d in 2003/2004 (refer Graph 5.1).
Graph 5.1 North Narrabeen Reserve historical water usage 2001/2005 Establishment of the new drought resistant turf in 2002/2003 accounted for the peak water usage over the period. Weekly monitoring was undertaken of the main meter and check meters from mid January 2006 over a four week period. Total site usage averaged at 19kL/d during the monitoring period. The monitored readings were found to be exceeding the water usage at the site, and services were traced in attempt to locate other system connections. Continuous monitoring was later installed on the meters, and a baseflow of 0.12L/s (about 10.1kL/d) was detected. Subsequently, sections of the system were isolated to detect and repair a leak which was located in the water service to the Park & Ride amenities. The leakage reduction measure has conserved about 17% of water being used at the site. Graph 5.2 indicates the relative breakdown of water usage at the site, based on monitoring data and observations from site inspections.

Graph 5.2 Indicative distribution of water usage at North Narrabeen Reserve
North Narrabeen Reserve is ranked third in terms of Councils highest water usage for 2004/2005, equivalent to a usage of 0.05kL/m2/annum. This reflects a significantly lower water usage than Sydney Water benchmarks of 0.4 to 0.6 kL/m2/annum for sportsgrounds. The reason for the low water usage is due to the absence of irrigation systems (prior to 2005), and the absence of a regular watering regime, resulting in generally dry field conditions. The current reduced irrigation regime is of ongoing concern to Council, who are keen to maintain the fields in acceptable conditions for safe playing. The impact is that projected needs to irrigate the fields to a sufficient standard will require higher water consumption. Recycled effluent from the nearby Warriewood Sewage Treatment Plant is an alternative water source that must be given serious consideration to meet this projected demand. Establishment of a sewer mining arrangement in partnership with Sydney Water, with supporting infrastructure for effluent reticulation and storage, further effluent treatment (either at the Sewage Treatment Plant or an alternative centralised site) to meet regulatory requirements, and new irrigation systems are to be considered as part of a scheme to service the Warriewood Valley/North Narrabeen area. (Further discussion is provided in a later section of this report). Results of the technical audit show that there are also several cost-effective, and potentially cost-effective opportunities for reducing water demand by: continuing to reduce systems leakage scheduling the replacement of remaining grasses on the fields with drought tolerant and salt resistant turf installing irrigation systems connected to water storage tanks (compatible with any future systems sourcing alternative water supplies) installing rain and soil moisture sensors, and undertaking seasonal benchmarking to optimise irrigation requirements toilet cistern maintenance and auditing for cistern leaks installing flow controls in showers capturing roof water off the function centre and amenities block for toilet reuse. These recommendations further reduce the water consumption significantly below current usage rates by about 68% from the 2004/2005 figures (without accounting for projected demand increases).

Graph 7.2 Indicative distribution of water usage at Narrabeen Golf Driving Range Narrabeen Golf Driving Range is ranked sixth in terms of Councils highest water usage for 2004/2005, equivalent to a usage of 0.08kL/m2/annum. Whilst no benchmarks are available, it is found to be of significantly lower water usage than the 0.2kL/m2/annum of Palm Beach Golf Club. The current reduced irrigation regime is a factor influencing the dry condition of the driving range fairway.
Results of the technical audit have shown that alternative water supply from effluent reuse could be useful if this was made readily available from a scheme to North Narrabeen. Other areas for water savings include encouraging through the lease arrangement to: continuing to reduce systems leakage collect roof water from the amenities and sheds for irrigation replace fittings in amenities with water efficient devices.
Review of Avalon Golf Course
Avalon Golf Course is a 9-hole, par 32 course situated on 13.5 hectares of undulating land. The course facilities are attended by approximately 32,000 club patrons per annum and include a club building with restaurant and amenities. Other facilities on the site include a greenkeepers cottage, service compound, and garage. The course is managed by lease, although Council greenkeepers undertake maintenance and course improvements, including the recently constructed stormwater retention basin. Course maintenance includes operating an irrigation system under water restrictions once a fortnight on tees and greens. Course works between 2000 and 2006 have resulted in the conversion of all greens to drought resistant turf, thereby significantly reducing irrigation requirements. Water is supplied by two main meters to the site and is mostly used for irrigation. Check meters are also fitted to the service to the cottage and the clubhouse.
A walk-through technical audit was undertaken of the site by Council.
Daily water usage over 2004/2005 was 6.4kL/d. The historical water usage over past years were 20.8kL/d in 2001/2002, 27.3kL/d in 2002/2003 and 9.2kL/d in 2003/2004 (refer Graph 8.1).
Note The spike is an anomaly and a result of meter malfunction.
Graph 8.1 Avalon Golf Course historical water usage 2001/2005 Note that the spike for the 08/03 to 11/03 quarter was a result of equipment malfunction and not water usage. Peak water usage generally occurs in summer due to increased irrigation. Weekly monitoring was undertaken of the meters from mid January 2006 over a four week period. Total site usage averaged at 7.4kL/d during the monitoring period. The main water usage can be attributed to irrigation. Water usage at the cottage was typical for household usage. The clubhouse amenities were newly installed with water efficient devices. The newly refurbished restaurant kitchen also had an array of water efficient fixtures. Graph 8.2 indicates the relative breakdown of water usage at the site, based on monitoring data and observations from site inspections.

Review of Governor Phillip Park & Surf Club, Palm Beach
Governor Phillip Park is situated on a linear piece of land forming the eastern side of the Barrenjoey Peninsular sand spit. The park includes an amenities block, North Palm Beach Surf Club and amenities, a commercial building, and several outdoor taps and shower towers. The facilities are most popularly used in the summer months, but have a constant usage over the other months. Some foreshore reserve showers and taps were replaced with water efficient spring shut-off fixtures in 2005, and some taps were changed to key operation. North Palm Beach Surf Club undertook some refurbishment of its amenities to include water efficient features in 2005, and is continuing to undertake further refurbishments in 2006/2007. A walk through technical audit was undertaken of the site by Council. Water is supplied by two main meters to the site.
Daily water usage over 2004/2005 was 10.1kL/d. The historical water usage over past years were 12.5kL/d in 2001/2002, 12.1kL/d in 2002/2003 and 10.6kL/d in 2003/2004 (refer Graph 10.1).

This could be compared to the figure of 10L/visitor/annum (Palm Beach Foreshore and Pavilion) as a comparative benchmark for water efficiency. This indicates that there are further opportunities to reduce water consumption at the site.
There are some cost-effective and potentially cost-effective opportunities for reducing water demand by: replacing remaining taps with water efficient fixtures (spring-loaded or key operated taps) replacing shower towers with water efficient fittings scheduling the replacement of fixtures in the amenities block with water efficient fittings on refurbishment.
Review of Newport Beach Foreshore & Surf Club
Newport Beach foreshore includes Newport Beach Surf Club and amenities, outdoor taps and shower towers. The facilities are most popularly used in the summer months, but have a constant usage over the other months. Some water efficient showers and taps were installed in the foreshore reserve and the men's amenities were fitted with some water efficient devices in 2003. The Surf Club have some water efficient features in its amenities including dual flush toilets and flow restrictors in some taps. A walk through technical audit was undertaken of the site by Council. Water is supplied by one main meter to the site.
Daily water usage over 2004/2005 was 9.5kL/d. The historical water usage over past years were 9.9kL/d in 2001/2002, 9.5kL/d in 2002/2003 and 7.1kL/d in 2003/2004 (refer Graph 11.1).
