of bulk services capacity from the municipality.
Authorization granted on 31 March 2011 and waste licence issued by Dept of Environmental Affairs on
23 August 2011.
The upgrade has been completed within the given estimated time frame of end 2012, a current letter
confirming this status was requested from the local Theewaterskloof Municipality and the letter is
attached hereto for ease of reference..
Environmental Control Officer, suitably qualified and experienced to be appointed by developer.
NB! EIA exemption granted due to the Dept being adequately comfortable with Aurecon’s competence
in managing the development process!
NEMA Principles of the NEMA section24(7) have been observed in the integrated approach to this
application, biophysical, social and economic.
Scope of Works:
A 53 Group Housing units with density of 15 units per ha and an average erf size of 407m2
B 62 Single Residential houses on 62 erven with a density of 5 units per ha and average size of 1160m2
Offices on a stand of 3755m2
Private Open Space of approximately 3.5hectares
Roads of approximately 1.5hectares
Retention Pond of 1.1hectares with capacity of 5000m3 at depth of 1m, with 525mm discharge pipe into
the Klipdrif River.
Engineering Services:
Alternatives Considered:
Alternative( 1) Preferred by client but not authorised!
Construction of a on-site sewer pump station
Construction of a 160mm sewer line to cross underneath the Klipdrif River and extend for 160m to
connect with the Molteno pump station along Arbor Drive road reserve for connection to the
Theewaterskloof WWTW provided capacity is available.
Construction of a 160mm water line from the existing water main in Arbor Drive across the Klipdrif River
to the development site.
This alternative will necessitate the following:
Abstraction of 109m3 of water from the boreholes on the northern border of the site.
Construction of a water purification plant on site to ensure that water is purified to potable water
standards.
Construction of a water reservoir with a capacity of 300m3 at the south-eastern corner of the site to
ensure sufficient water capacity to meet the expected demand for a 48 hour period.
Construction of a on-site predesigned approved unit WWTW with 30 000m3 per annum capacity, to be
located at the south-eastern corner of the site. Treated effluent to be released into the Klipdrif River and
sludge to be removed to the municipal sludge drying beds.
Caution!!! There is risk of environmental contamination of the Klipdrif River.
Alternative (2) (Off-site Services only) Authorised
Construction of a sewer pump station on adjacent site Erf 116 with 160mm sewer main extending 310m
in total, across the southern border of the proposed site and crossing under the Klipdrif River adjacent
to Erf 69, along municipal land and connecting to the municipal pump station on Industria Rd for
disposal into the Theewaterskloof WWTW.
Construction of a new 160mm water pipeline from the water main on Industria Rd extending in total
310m across adjacent municipal land and under the Klipdrif River across the southern border of the
property into the proposed site.
The site falls within the 1:100 year flood line. The Klipdrif River will be widened along the eastern and
south eastern boundaries of the Farm No.296 from approximately 8m to approximately 18m on the left
bank to ensure that the proposed site falls outside the 1:100 year flood line. The proposed development
also entails the infilling of the north-eastern corner of the property. The Klipdrif River will also be
widened along the southern boundary of Portion 11 of the Farm No. 287, for a distance of
approximately 300m.
Engineering Services Design:
The Engineering Services Design for the authorised alternative (2) as above, and modification of the river
bank has to date not yet been done, this will be completed by Aurecon in due course.
Proposed Mitigation Measures:
Temporary River Diversion
The river flow is to be diverted past the construction area via a temporary pipeline.
The dry stream bed is to be covered with a geo-textile fabric that can be removed after construction,
leaving the streambed clean.
Silt traps to be placed on top of the dry protected stream bed to catch any water pumped from
excavations to drop out any silt before the water is returned to the river downstream.
Water pumped from excavations must be pumped to sediment dams situated well away from the river
where the dams can be allowed to overflow through the existing plant cover back to the river. This
process must be well managed to ensure that no erosion takes place during the process.
Silting and bank erosion
Adequate silting fences will be required to protect embankments where construction is to take place.
Walkways in the form of boardwalks are to be constructed on the river bank in the construction area, in
such a way that workers do not walk or handle equipment directly on the river bank or in the river bed;
The construction site should be fenced in such a way that the main stream and surrounds are managed
as a no-go area.
No eating, ablutions or latrines, or casual urination is to be allowed in the construction site area.
Drinking water and water for construction is to be abstracted from the river at one designated point
only and piped to the site camp and or the construction site. No one should be allowed to take water
from the river for any reason at any other point than the designated point.
Abstraction of water should conform to all regulations as determined by the Department of Water
Affairs.
Disruption of the flow of the existing storm water to the river
All storm water discharge to the area is to be diverted down-stream of the new works area before
construction work commences, even if construction work is not undertaken during the rainy season.
Pollution from construction works
All plant in the area to have drip trays.
No servicing of plant to be allowed anywhere except on the service area at the site camp.
Refuelling of plant to make use of drip trays to prevent spillages.
All cement work to be carried out using cement trays.
Batching plant protection to be effected as per the recommendations for the eastern portal works.
Site camp management including oil traps, drip trays and conservancy tanks as per the western
construction site management recommendations and to include siting of the camp as far away from the
river environment as possible.
The entire construction area and construction camp should have enough suitable refuse removal
containers and a daily refuse clean up system in place to prevent any litter pollution from entering the
river.
Geotechnical Conditions:
Class C1 and C2 soil types only.
Summary of Findings:1) The proposed site for the development can be divided into two distinct areas onthe basis of the surface gradient and layout of the residential estate, namelyArea A and Area B.• Area A slopes gently downwards to the south, towards the Klipdrift Riverand is vegetated with grasses and lined with small to medium apple trees.• Area B is level and has been cultivated with apple and pear trees ofbetween 2 m and 4 m in height. Studies have indicated that, underexisting conditions, a large portion of this area would be inundated during
1 in 50 year flood events.
The residential site class designation (as adopted by NHBRC4) of the soil profile forthe proposed development site is shown to be:• Area A: C1• Area B: C1/C2C1 - Compressible and potentially collapsible soils with expected range of total soilmovement of 5 mm to 10 mm.C2 - Compressible and potentially collapsible soils with expected range of total soilmovement of greater than 10 mm.
Recommendations:(i) Flooding: The hydrological study carried out by Ninham Shand has shown thatimprovements to the stream and river channels on the northern and westernboundaries of the site together with localised infilling of the of the north-easterncorner of the site, would prevent inundation from floods up to the 1 in 100 yearevent.
Foundations:
The consistency of the soils underlying the site is very variable with loose to very loose material.
The least risk option for founding the one and two storey residential units will be to use raft foundations
in Area B. Units in Area A could be founded on lightly reinforced footings after having wetted and
compacted the foundation trenches. An alternative approach to Area B, will be to use raft foundations
along the western edge of the site and along the riverfront properties, along the southern edge. The
units within the central portion of area B may be founded on spread footings at depth of 0.5m after
having prepared the founding material by excavation to 800mm, compacting the trenches and
reinstating, with good compaction, using acceptable imported fill (free of organic matter), in layers not
exceeding 150mm to above the -50mm proposed founding level. Further trial holes and testing will be
required to confirm the in situ conditions along the eastern edge even before the strip footing option is
used, (in place of raft foundations).
Excavation:
Excavation down to 1.5m depth will be in soft materials. Groundwater was encountered at depths of
between 1.3m and 2.5m below natural ground level. However the water table may rise during the
wetter, winter months and, should construction be carried out during this time of year, might lead to
the inundation of foundation excavations.
The in situ sandy materials are classified as G7/G8 in accordance with TRH 14, Guideline for Road Construction Materials and are of marginal quality in respect to their suitability as selected layers for road pavements.
