Project DescriptionProject DescriptionProject DescriptionProject Description
In 2005 the Richmond Municipality requested that Umgeni Water consider supplying potable
water to the town of Richmond as the existing water supply systems were proving
problematic and unsustainable. Umgeni Water has thus proposed the construction of a
pipeline from its ’61 Pipeline system to serve the town.
The project will serve the potable water demands of the greater Richmond area (initially
8.3Ml/day and ultimately 14 Ml/day) and will also tie into Umgeni Water’s existing Thornville
sub-system (Section 5.2.1), which is currently served from the Thornville Pump Station
situated on the ‘61 Pipeline between ED2 and Umlaas Road. The project will be fed off the
’61 Pipeline downstream of the ED4 take-off. A new pump station is required to lift the
water to a new reservoir (Liliefontein Reservoir) sited near Thornville. The proposed
Richmond Pipeline will run along the R56 main road to Richmond (Figure 7.14). The existing
Thornville Pump Station will be decommissioned and the rising main with revert to a back
feed gravity main once the Richmond Pipeline is in operation. The pipeline will terminate at
the municipal reservoir that serves Richmond.
Key information on this project is summarised in Table 7.15.
Table 7.15 Project information: Richmond Pipeline.
Project Components: 31 200 m long section of 450 mm diameter pipeline and a new booster
pump station.
Capacity: 27 Ml/day.

sell potable water from this system to The Msunduzi Municipality and Umgungundlovu
District Municipality as per existing bulk water supply agreements.

Project DescriptionProject DescriptionProject DescriptionProject Description
Umlaas Road Reservoir initially served as balancing storage for the Umlaas Road WTP. The
WTP was decommissioned in 2002 as sufficient potable water could be transferred to the
Umlaas Road demand node via the ’61 Pipeline. The reservoir complex was retained and
currently serves the Outer Western areas of eThekwini Municipality via the ’57 Pipeline and
the Eston/Umbumbulu and Lion Park pipelines. The reservoir site is situated to the east of
the N3 National Road, just north of the N3-R603 interchange (Figure 7.15). The reservoir
complex consists of two separate reservoirs, viz. the original 9 Ml reservoir and a later
45 Ml reservoir. The reservoir complex currently serves as both a break pressure and
balancing storage facility and can be supplied from Midmar WTP via the ’61 Pipeline and
from D.V. Harris WTP via the recommissioned ’53 Pipeline.
It is necessary to provide at least 15 hours of balancing storage at Umlaas Road in order to
cope with the peak demands placed on the supply system by the downstream consumers. It
is therefore recommended that an additional 45 Ml reservoir be constructed in advance of
the commencement of the proposed Western Aqueduct load transfer in 2014. This will
ensure that there is sufficient storage in place to accommodate the load transfer until at
least 2022, by which time the Western Aqueduct demand should have been transferred
across to the Mkomazi Water Project (Section 7.2.1).
Key information on this project is summarised in Table 7.16.

Project Components: New 45 Ml reservoir.
Capacity: 45 Ml.

Umgeni Water will build, own, operate and maintain all water supply infrastructure
pertaining to this project.
BeneficiariesBeneficiariesBeneficiariesBeneficiaries
The upgrade to the Umlaas Road Reservoir Complex will benefit all consumers downstream
of the reservoir. These beneficiaries are primarily the eThekwini Municipality, but also
include consumers within the Mkhambathini Municipal areas of Umgungundlovu District
Municipality.

Project DescriptionProject DescriptionProject DescriptionProject Description
The Greater Eston area falls within Wards 4 to 7 in the Mkhambathini Local Municipality and
Ward 5 and 7 of the Richmond Local Municipality. These local municipalities fall within the
jurisdiction of the uMgungundlovu District Municipality (UMDM).
The bulk water supply to the Greater Eston area as depicted in Figure 7.16 requires three
off-takes on the Eston-Umbumbulu Pipeline.
The first off-take will supply the uMacalagwala area. The second off-take will supply the
following areas:
• Esigodini/Gulube
• Ismont
• Mpangisa
• Embuthweni
• Inhlazuka
• Ukhalo
The third off-take will supply the Ogagwini area.
Key information on this project is summarised in Table 7.17.

The scheme is jointly funded by DWA, Umgeni Water and Umgungundlovu District
Municipality through its MIG allocation. The proposed scheme will be operated and
maintained by Umgeni Water. Bulk water contracts will be entered into with
