The Bidder shall be responsible for all negotiations with local authority/WASA where a connection to a
public sewer is proposed. Where high water levels in public sewers may cause effluent to back up into
a site, non-return valves shall be fitted. The Bidder shall provide all protection required to existing
sewers and shall deepen foundations, including boundary wall foundations, where required to ensure
all foundations are below adjacent sewers. The Bidder shall draw longitudinal sections of all pipelines.
Main control building shall be provided with a septic tank designed for 10 users and a soakaway of
open brick construction 11m deep by 2.2m diameter filled with broken bricks. The septic tank shall be
located at least 15 metres from buildings. Other buildings shall have septic tanks designed for the re-
quired number of users. All foul drains shall be vented by a vent pipe to above roof level. The inner
surface of all manholes and septic tanks shall be painted with 2 coats of bitumastic paint to protect it
against sulphate attack. The septic tank shall have access holes directly over the inlet pipes and outlet
pipes. Where public sewers exist alongside a site, the Bidder shall connect directly to the foul sewer,
provided effluent from the sewer is treated.
The Bidder shall construct the drainage first to ensure that at no stage is rainwater ponded on any part
of the site. All rainwater shall be able to run off the site or shall be immediately pumped off site by the
Bidder. The Bidder shall complete all necessary drains before casting any roof and large concrete ar-
ea which will create large run off. The condensate drains for the air conditioning shall also be connec t-
ed to the drainage. Two vents of minimum height 2.2m shall be provided on each septic tank.
10.1.3.4 Surfacing
For the whole of the switchyard outdoor equipment area the ground shall be surfaced with gravel or
other readily available local stone as approved by the Engineer. The switchyard surfacing shall be
clean, thoroughly washed when necessary, and free from clay, soil or contaminating material and shall
be graded from 20 - 45mm, laid and lightly compacted to a finished thickness of 175mm. Below the
gravel layer there shall be a 75mm brick layer with cement mortar (1:6), laid over a 75mm level of fine
sand spread over the finished fill site.
The substation plot, outside of the designated switchgear equipment areas, shall be turfed. Turf shall
be of good quality, free from weeds and shall be a minimum of 40mm thick. Samples of the turf which
is proposed to use shall be submitted to the Engineer for his approval. The turfs shall be laid to even
surfaces on a bed of vegetable soil, which shall be raked and consolidated to provide a suitable bed.
On sloping surfaces the Bidder shall provide and fix wooden pegs to retain turfs.
All areas to be surfaced shall first be treated with a total weed killer in accordance with the Manufac-
turer's instructions. Weed killer shall only be applied in dry weather when there is no risk of it being
washed out to adjacent agricultural areas.
10.1.3.5 Roads
Access road from outside of the site boundary that connects adjacent public road and all roads within
the site boundary shall be provided by the Bidder. The road surface shall be finished by concrete pav-
ing or equivalent. All roads shall be of reinforced slabs of minimum 15 cm thickness fitted with con-
struction joints at distances not exceeding 6.0 m. Paving schedule and methodology shall be approved
by the Employer. The extent of roads required is shown approximately on Bid drawings but the scope
