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.

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.

Table 7.16 Project information: Umlaas Road Reservoir Upgrade.

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.

The construction duration of this project is anticipated to be one year. The total cost is

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

Umgungundlovu District Municipality.
