Consideration shall be given to the physical flow and pressure constraints of the site and pipework sized accordingly. Pressure reduction valves shall be incorporated into the design where mains pressures exceed 500kPa to domestic fixtures and fittings.

1 No x 300,000 litre rainwater collection tank and its outlet pressure pump / filter unit will provide pressurised rainwater to toilet pan flushing valves and hose taps for Wash-down.

In the event of low rainwater levels in the tanks or power supply failure to the pump, a potable cold water supply back up shall automatically by pass the rainwater reuse pump set and service those fixtures and taps connected to the rainwater reuse supply using town’s main non potable cold water supply.

The rainwater reuse service shall be adequately labelled and identified in accordance with AS 3500.1.

Where non-potable services are required, all backflow prevention devices shall be located so as to provide zones of protection to the required areas. Where located externally, the devices shall be mounted inside a lockable enclosure with circular vent port outlet cut in the base and sized to suit the device

The Cold Water Services within / adjacent the theatre will be designed to prevent the likely hood of acoustic noise and vibrations from plant and equipment entering the space.

4.3 Stormwater / Roof water System The design, construction and operation of the cultural precinct rainwater systems must comply with

1. State Planning Policy SPP 4/10 – Healthy Waters and;

2. State Planning Policy SPP 4/11 - Protecting Wetlands of High Ecological Significance in Great

3. Barrier Reef Catchments

4. Recommended minimum stormwater design objectives as shown in Chapter 2 of the ‘Urban Stormwater Quality Planning Guideline’ (2010) shall be adopted.

The design solutions shall incorporate quantifiable objectives for permanent water management infrastructure, and shall reflect achievable and tested regionally specific design requirements for

SPP GROUP 9 Hydraulic Services Consultants REV. 2

planning and development to ensure water sensitive urban design (WSUD) is implemented in a consistent way to help achieve water quality objectives (WQOs) in receiving waterways.

The design and construction of the Stormwater Drainage Systems shall address and satisfy the environmental and sustainability requirements adopted for the development;

Achieve a high quality of rainwater discharge to Hartley Street and eventually Trinity Inlet to meet SPP guidelines;

Maximising the runoff from the roof catchment areas to enable the highest possible uses of rainwater on site and maximise the reduction in potable water demand;

The design objectives include rainfall capture (300KL on site tank), peak discharge limits, and reductions in contaminant loads for nutrients, gross pollutants, and total suspended solids.

The design and construction of the Stormwater Drainage Systems should also ensure that if the basement car park option is taken up then it is protected from stormwater surcharge and Q100 Flood Levels. It would be anticipated this would be achieved by all entrances and exits pavement levels to the basement being above the designated Q100 flood level.

The Roof Drainage within the building will be designed to prevent the transference of acoustic noise and vibrations from flowing water through pipework from entering the space.

4.4 Rain Water Reuse System 1 No x 300,000 litre rainwater collection tank and its outlet pressure pump / filter unit will provide pressurised rainwater to toilet pan flushing valves and hose taps for Wash-down.
