2 Site�Specifics�

The� new� 2� storey� building� will� house� the� Nauru� USP� and�Community�Centre�and�Library.�It�will�be�located�on�the�site�of�the�old� Department� of� Works� warehouse� located� between� Nauru�Secondary� School� and� the� Police� Headquarters� Building� opposite�the�Nauru�airport.� �

5 Geotechnical�

There�is�no�available�geotechnical�information�for�the�site�hence�KA�will� undertake� designs� of� the� footings� assuming� a� minimum�allowable� bearing� capacity� of� the� founding� material.� The� bearing�capacity� of� the� founding� material� must� be� verified� on� site� by� a�


geotechnical�engineer�prior�to�construction.�Should�the�existing�soil�bearing�capacity�be�less�than�that�assumed�in�the�design�then�the�geotechnical� engineer� shall� provide� recommendations� for�improving�the�founding�material�or�alternative�footing�system�to�be�adopted.�The�following�items�are�some�assumptions�KA�have�made�with�respect�to�Geotech.�

5.1 Subsoil�Stratum�

The� stratum� is� believed� to� comprise� of� medium� to� coarse� coral�sands�and�gravels�overlying�limestone��

5.2 Site�Subsoil�Category�

Site� subsoil� category� is�believed� to�be� firm�or� stiff� as� limestone� is�likely�to�be�near�the�surface.�

5.3 Liquefaction�Potential�

There� is� likely� to� be� a� low� risk� soil� liquefaction� potential� due� to�relative� lack� of� soil� and� the� nature� of� the� soil�which� are� typically�coarse�sands�and�gravels.�

5.4 Settlement�

There� is� ground� settlement� or� subsidence� risk� due� to� unknown�locations�of�cavities�formed�by�dissolution�of�the�limestone.�

5.5 Ground�Water�

Depth�to�groundwater�could�be�variable�possibly�with�levels�across�the� site� influenced� by� sea� levels� and� could� fluctuate� with� tidal�movements.�

5.6 Footing�

KA�propose� shallow� spread�pad�and� strip� footing� system� founded�on� the� natural� soil� (coral� sands� and� gravels).� KA� will� design� the�footings� to� be� founded� on� material� with� minimum� allowable�bearing�capacity�of�100�kPa.�All� footings�to�be�founded�above�the�ground�water�table.�

NAURU USP WATSAN STRATEGY

WATER SUPPLY According to the Pacific Climate Change Science Program;

“The main driver of climate variability in Nauru is the El Niño-Southern Oscillation (ENSO). La Niña events are associated with delayed onset of the wet season and drier than normal wet seasons, often resulting in an extended drought.” “During El Niño, temperatures on Nauru are warmer than normal due to warmer sea temperatures; and rainfall and cloud amount are increased.” “Another key climate driver for Nauru is the Inter-tropical Convergence Zone (ITCZ). The ITCZ affects Nauru all year round. Its seasonal north/south movement drives the seasonal rainfall cycle, which peaks in Dec-Feb. See the following plot:

“Thewet

season usually starts in November and continues to April of the next year. During the wetter months, winds are generally from the west at 10- 18 knots. During the drier months of May to November, the prevailing wind direction is generally easterly at 5-10 knots. There is a weak peak in rainfall during July-August associated with the northward displacement of the SPCZ. “ “The annual rainfall of Nauru has extremely high variability (standard deviation 1,280mm); a result of the strong ENSO influence. In some La Niña years Nauru only receives around 500 mm of rainfall, whereas in El Niño years rainfall can be as high 4,500mm.” “The main climate extreme experienced by Nauru is drought, which can last as long as 36 months. Droughts occur when La Niña events decrease the surrounding sea temperature, resulting in less cloud and rainfall. “ In most months rainfall variability is significant with rain falling on between 10 and 15 days in significant storms.

Climate Impact on the Project Nauru has three sources of water supply:

� A brackish freshwater lens pumped from wells; � Rainfall collected from roof catchments and stored in

tanks; � Desalination supply;

During periods of drought the first two are significantly stressed and the whole island depends on the third source, distributed by tankers.

�

Because of this all projects rely on at least two sources of water. The USP will rely on the second two. To do this the proposed system will require cost effective storage of roof runoff to optimize rainfall availability and survive short drought periods and rainfall variability and the opportunity to receive tanker deliveries in more severe climate events.

Existing Infrastructure The TVET built in Stage 1 has a roof area of 449 m2 and total storage connected to the guttering of 20,000 liters (2 tanks 5,000L and 15,000L). Although the demand is very low mean annual yield from this roof area is almost 700kL. Of this quantity only approximately a quarter is used within the building resulting in a loss of around 500kL of water to the sea. The TVET has overflow pipes from the tanks to the sea.

As noted by PCCSP mean annual rainfall can vary between 500mm and 4,500mm and it is prudent to store as much of that as possible.

The TVET tanks are interconnected and a pressure pump delivers water to the two bathrooms, kitchen and washing up facilities.

USP Concept Design The USP design includes 4 toilets and a kitchenette catering for up to 150 EP. Average daily facility usage would be 60 students and 15 teachers. Based on Australian Standards, daily water demand would be between 15 and 20 l/head, resulting in a total daily water demand of between 1kL and 3kL.

Water Demand/Storage Balance

Based on the long-term mean monthly rainfall figures for each square meter of roof catchment 1.55kL of water is available for storage.

If demand is average then the catchment from the TVET building alone with a total storage of 100kL will provide security in mean years and in years where variability has an impact with extreme events up to 3 months.

However, if the maximum demand occurs then the total catchment of both the USP and the TVET, together with storage of 100kL is required for security.

Proposed Water Strategy The proposed water strategy for the USP is as follows:

� Provide a 100kL storage tank adjacent to the TVET 15kL tank and interconnect them. This can be a Southern Cross tank with liner;

� Connect all roof guttering to the interconnected tanks to achieve 120kL total storage with overflow to the sea;

� Upgrade the existing pump set to meet the demand in both the TVET and USP;

� Provide the USP with Australian Standard plumbing and water saving devices to minimize wastage;

� Connect the USP hydraulics to the TVET hydraulics at a convenient point. Taking account of flow and pressure requirements for outlets and the potential for water hammer;

�

WASTEWATER

Existing Infrastructure The TVET building has a wastewater system that collects all waste from two toilets, a kitchenette, hand basins and washing tubs. The tubs where lubricants and petroleum products are used is separated from the main pipeline and this passes into a separate pit with snorkel to remove any build up of explosive gasses. The domestic wastewater passes to two 2500L plastic septic tanks in sequence and thence to a distribution box and infiltration field.

The waste pipework is standard nominal 100mm and capable of taking the additional USP wastewater low downstream.

The design of this system incorporated both the TVET and future USP return flows to mean daily average of 1kL and a maximum of 3kL.

All wastewater from the USP will be domestic and can be delivered to the septic system.

Proposed Wastewater Strategy � Provide the USP with Australian Standard waste

plumbing; � Connect the USP hydraulics to the TVET hydraulics at

a convenient point. Taking account of flow, gully and vent requirements;
