  • Developments in the design and construction of the individual units of the hydraulic service system of the present invention has resulted in the improved performance of the services together with a reduction in the cost of labour and materials in the installation of the services.
  • the hydraulic service system of the invention includes all three service units, it will be understood that the various innovative modifications and improvements described herein may be made to any one or two of the sanitary plumbing service, hot water service or cold water service units and still be within the scope of the present invention.
  • further modifications and improvements may also be proposed to the hydraulic service systems without departing from the spirit or scope of this invention.
  • Each of the three main service units of the hydraulic service system are discussed in turn below.
  • the sanitary plumbing service for use in the present invention is preferably a single stack unvented sanitary system for conveying waste liquid to a sewer.
  • the system utilises the implementation of a single stack in which to convey all soil and waste discharges from all plumbing fixtures, without the requirement of venting, for use in buildings up to 30 stories high.
  • the provision of the single stack unvented system eliminates the need for installation of any pipe work for the purpose of venting, and provides a cost efficient alternative to fully vented systems.
  • the sanitary plumbing system may be compartmentalised as required for use in buildings of significant height, such as greater than 30 stories, or due to any unique architectural design.
  • the sanitary plumbing service required for such tall or unique buildings often requires the implementation of inefficient hydraulic service installations in order to meet various national plumbing and drainage codes.
  • the single stack unvented sanitary system used in the hydraulic service systems of the present invention maybe utilised in a compartmentalised sanitary plumbing system to overcome particularly inefficient and di ficult installation and associated costs in order to adhere to conventional code requirements.
  • the compartmentalised system can utilise the single stack unvented method covering a maximum of 30 stories.
  • a number of compartments may be employed as required to service buildings taller than 30 stories and buildings with unusual designs. Each of the these individual compartments drain to a dedicated express stack which conveys the sewage down to the sewer connection point.
  • compartmentalised sanitary plumbing system allows the single stack unvented method to be applied to tall buildings without an upper limit, maintaining satisfactory system performance whilst offering considerable cost savings.
  • the pipe work for sanitary plumbing services is typically underslung on each floor level which requires the need and expense for false ceilings and bulkheads, sound baffles and access to the floor below when maintaining or servicing the sanitary plumbing system.
  • the sanitary plumbing system is preferably relocated to within the concrete floor slab obviating the need for underslung pipe work on each floor level below. This system utilises the concrete floor slab within the wet rooms of apartments and hotels in which to install the sanitary plumbing pipe work from the fixture outlets.
  • the pipe work can be installed in the concrete floor slab without any wrapping membrane when the pipes are constructed from suitably durable materials such as high density polyethylene (HDPE) pipes and fittings in accordance with building standards. Judicious selection of materials and specialised fittings can allow for the accommodation of the horizontal sanitary plumbing pipe work in concrete floor slabs to a minimum thickness of 200 mm. Containment of the pipe work within the concrete floor slabs meets the acoustic requirements of building codes and obviates the need for underslung sanitary plumbing.
  • HDPE high density polyethylene
  • the floor waste gully and shower waste gully of the sanitary plumbing service may be combined.
  • This utilises the shower grate as a dual purpose fitting thus deleting the requirement for a floor waste gully typically located in the centre of the wet room floor. This may be achieved by allowing for the wet room floor to drain into the shower recess and to the shower waste gully.
  • the shower recess may utilise a shower screen that continues down to the floor surface where a series of small slot openings are provided for in the frame of the shower screen at the floor surface level.
  • the floor surface is tiled whereby the tiles are layed with an increased grade, falling to the shower grate within the shower area which will allow the entire wet room floor to be graded to the shower grate. Deletion of the floor waste gully reduces the installation costs and increases installation speed of the wet room during construction.
  • the laundry floor waste gully may be omitted by the provision of laundry tubs with an internal overflow built into the tub bowl and the use of flood stop valves on the hot and cold water outlets for the washing machine.
  • the provision of the laundry tub having an internal overflow built into the tub bowl prevents the flooding of the laundry floor due to the laundry tub overflowing.
  • the internal overflow simply conveys any excess water back to the waste pipe below the tub bowl.
  • the potential flooding caused by the bursting of the washing machine hoses is overcome by the installation of flood stop valves on the hot and cold taps.
  • the flood stop valves automatically close upon detection of a burst hose.
  • Use of an internal overflow built into the laundry tub bowl and flood stop valves on the hot and cold water taps allows for the omission of the laundry floor waste gully which can reduce installation costs and increase the installation speed over the sanitary plumbing system during building construction.
  • the hot water service utilised in the hydraulic service system of the present invention includes a centralised boiler feeding a main hot water distribution pipe extending to each floor of the building where hot water is required, whereby the hot water distribution pipe has a manifold at each floor for the supply of hot water to one or more rooms of the building.
  • the hot water distribution pipe is insulated and fitted with a plurality of heat trace cables and thermostatic mixing valves connected to a centralised temperature control system.
  • the centralised temperature control system maintains the required hot water temperature throughout the hot water distribution pipe extending through the floors of the building.
  • This system is suitable for both metallic and non- metallic piping materials, such as thermal plastics.
  • This heat trace system eliminates return lines, flow and return pumps, balancing valves and air release valves in order to recirculate the hot water thereby reducing heat loss and lowering the cost to install, run and maintain the system.
  • the desired hot water storage and delivery temperatures are achieved by utilising a centralised temperature control system, which through a series of thermostatic mixing valves and temperature sensors stores and distributes the hot water at any pre-determined temperature.
  • the centralised control of the system maintains the required design temperatures and pressures in the main hot water distribution pipe extending to each floor of the building to provide a satisfactory performance to all fixture outlets.
  • the performance of the hot water supply may be greatly improved by having both the hot and cold water supplies function at similar pressures and flows, thereby providing a more uniform, balanced and controlled hot water delivery to each fixture outlet.
  • the age-old problem of pressure and temperature fluctuations whilst showering is addressed by the hot water service utilised in the present invention.
  • the centralised control of the hot water allows the building management to control the energy consumed by the hot water plant.
  • the energy consumed by the hot water plant is demand driven by simple cable connection between the hot water plant room and the management system of the building.
  • additional hot water plant can be activated automatically allowing only the necessary energy to be consumed.
  • the hot water plant can be progressively de-activated so that the energy consumed is reduced, being solely driven by demand.
  • Control of the energy consumed by the hot water system may be achieved by the centralised boiler comprising a plurality of individual water heaters connected in parallel to the hot water service. As the hot water demand increases or decreases, the individual water heaters may be switched on or off to ensure supplies are available to meet demand.
  • government and regulatory bodies require hot water systems to heat water to a given temperature such as 60°C or more and store the water for a period of time sufficient to kill legionnaires' bacteria and other microbes.
  • the delivery temperature of hot water to fixture outlets is typically regulated to a maximum of 50°C.
  • temperature regulation is achieved by the installation of a temperature limiting valve to each hotel room or apartment.
  • the hot water service of the present invention utilises the centralised temperature control system to regulate the temperature in the main hot water distribution pipe.
  • This system utilises a series of thermostatic mixing valves installed adjacent to the hot water plant in a manifolded configuration. From these valves water is supplied from the centralised boiler to the main hot water distribution pipe and up to the fixture outlet at a maximum temperature of 50°C.
  • the centralised temperature control system and the thermostatically controlled main hot water distribution pipe eliminates the need for a temperature limiting valve to be installed in every hotel room or apartment.
  • the centralised system reduces installation costs of the hot water service and provides a more accurate and controlled hot water temperature delivery to each fixture.
  • the hot water is distributed to each hotel room or apartment by a fully retrievable poly pipe installed in a conduit cast within concrete slab floors of the building, which maintains pipe work retrievability if required.
  • the main hot water distribution pipe manifolds may have a plurality of meters to individually monitor the water supplied to each serviced room.
  • the manifold and meters maybe installed in one central cupboard on each floor supplied with hot water, and prelerably the cupboard is a fire hose reel cupboard, utilising the often empty space in such cupboards.
  • the present system provides reduced installation costs, reduced running costs, equally balanced hot and cold water pressure, obviates the need for access into each apartment for meter reading or maintenance and eliminates the need for hot water mains within each apartment, resulting in more useable floor space and the elimination of noise and heat from the mains.
  • the cold water service utilised in the hydraulic service system of the present invention includes a main distribution pipe similar to that of the hot water system.
  • the main distribution pipe extends to each floor of the building where cold water is required, whereby the cold water distribution pipe has a manifold at each floor for the supply of cold water to one or more rooms of the building.
  • the cold water is distributed to each room by a fully retrievable poly pipe installed in a conduit cast within concrete slab floors of the building, which maintains pipe work retrievability if required.
  • the cold water distribution pipe manifold has a plurality of meters to individually monitor the water supplied to each serviced room.
  • the manifold and meters are installed in one central cupboard on each floor supplied with cold water.
  • this cupboard may be the fire hose reel cupboard or another cupboard specifically designed to accommodate the hot and cold water manifolds and meters.
  • the cold water distribution pipe also supplies water to each fire hose reel as it passes through all floor levels of the building.
  • the supply pipe is sized to cater for the demands of the building. In addition the entire system maybe maintained at the required design pressure in order to provide a satisfactory performance to all fixture outlets.
  • the present system achieves a reduction in installations costs, equally balanced hot and cold water pressure, obviates the need to access each apartment for meter readings or maintenance and the centralising of all valving and metering in each fire hose reel cupboard.
  • the preferred storm water drainage system for use in the hydraulic service system of the present invention embodies a syphonic drainage system.
  • the syphonic storm water drainage system utilises the creation of a negative pressure (syphon) within the piping network of the storm water drainage system to convey large quantities of storm water at high velocity to a storm water drainage discharge point.
  • the negative pressure may be generated by a small diameter piping having substantially no grade installed on the piping network at a minimum head above the storm water drainage discharge point.
  • the storm water drainage system may be purposely engineered by those skilled in the art to cope with the rain fall conditions the building typically will be subject to and given the roof catchment area of the building.
  • the advantage of the syphonic storm water drainage system includes cost savings in the supply of fewer down pipes, smaller diameter piping and less bracketing to fix the piping.
  • the hydraulic system of the present invention preferably includes a gas service including a vertical gas riser extending to each floor of the building where gas is required, whereby the vertical gas riser has a manifold at each floor for the supply of gas to one or more rooms of the building.
  • the gas may be distributed to each room by a lagged copper pipe cast within concrete slab floors of the building.
  • the vertical gas riser manifold has a plurality of meters to individually monitor the gas supplied to each serviced room.
  • the manifold and meters may be installed in one central gas supply cupboard, and the cupboard may be separate to or the same as that used to house the hot and cold water manifolds and meters.
  • the supply piping to each hotel room or apartment may be used to supply gas to any area of the apartment as required, such as to the cook top . for room heating, to the balcony barbecue, and the like.
  • the advantage of the gas service of the present invention is the requirement for only one gas riser and the central location of all the valving and metering in one cupboard located in a common area. This system obviates the need for several individual risers, and valves and meters within apartments requiring greater quantities of piping installation time and difficulties in accessing meters for reading.
  • the hydraulic service system of the present invention preferably includes the provision of a fire service as mentioned above.
  • the fire and domestic cold water system is combined where in the event of a fire, the building management would adopt a fire mode which requires all occupants to vacate the building. At no time would both the fire and cold water services be required to be utilised simultaneously, reducing the requirement for individual piping for both cold water and fire services to the building.
  • the fire service, hot water service and cold water service may be pressurised by the mains, or pressurisation may be assisted by a service pump, if required.
  • a service pump typically hydraulic service systems utilise a first pump to maintain the domestic supply, with a second, dedicated pump sitting idle for the fire service.
  • the hydraulic service system of the present invention preferably combines the two individual pump sets, by the supply of water to each respective service by the one pump set.
  • the pump is sized to satisfy the larger demand of either service and has the advantage that the fire service is connected to the pump used daily in order to maintain the domestic cold water supply, rather than being connected to an idle pump, only being tested periodically.
  • the improvements gained by the combined fire and domestic cold water system offers significant cost savings in the supply and maintenance of the pumping plant and equipment, whilst also improving the performance and reliability of the services.
