WATER treatment works for Paarl, to supplement the current supply from the Wemmershoek Dam, are likely to be erected on Paarl Mountain at a cost of about R10 million, but conservationists are opposed to the project.
A draft scoping report to ascertain whether a full impact assessment of the project is required, indicates that the best location for water treatment works to improve the water supply for Paarl, would be at Pienaarskamp on Paarl Mountain.
The high location is proposed to improve the quality of the water supply and pressure, especially in the higher lying residential areas.
The treatment works will purify the water from the Bethel and Nantes Dams on Paarl Mountain, which is supplemented by water pumped from the Berg River.
About 8% of Paarl receives its water from this source. The water is corrosive and turbid and needs to be filtered, according to the report.
The project has been proposed due to the growing population of Paarl and the high cost of purchasing Wemmershoek Dam water from the Cape Town City Council.
The proposed plant would have a capacity of 8 million litres per day and will be erected next to Jan Phillips Drive, at the turn-off to the Paarl Mountain Reserve.
It could possibly later be expanded to provide 15 million litres per day.
The building is envisaged as a new 'gateway' structure to the nature reserve, stengthening the existing 'sense of place'.
However visual considerations play an important role in the ultimate location, layout, usage, architectural design and finish.
According to the draft scoping report of consulting engineers Ninham Shand, the building must blend into and complement the surrounding landscape, rather than attempting to 'hide' the proposed structure.
Sensitive site planning, landscape and architectural design will be required to mitigate the visual impact of the large building of 650 square metres and five to six metres high.
The design proposed is a curved roof covered with copper sheeting which will discolour with age to blend in with the indigenous fynbos vegetation.
The building will be partially cut into the existing slope to diminish its considerable visual impact, according to the report.
It could also provide security, parking, toilets and educational information for tourists, thus serving as a gateway structure to the reserve adding a "sense of arrival".
Two drying ponds with a physical footprint of 1800 square metres are also required, but the existing ponds located downstream at Blake Street could be used, according to the consultants.
Alternative sites for the construction of the plant and treatment dams are the northern section of the Zanddrift sportsfields or vacant land between the Dal Josaphat railway station and the sewerage works (near the Long Street bridge).
However, Paarl Mountain is the preferred site due to the need for improved water pressure in the higher residential areas.
At a public meeting, members of the public expressed their alarm at the plans to build the large building on Paarl Mountain, which is a declared heritage site.
The Drakenstein Heritage Foundation has called on the Department to withhold permission for the project and to appoint an independent organisation to compile a report after consideration of all reasonable alternatives.
"In our opinion the current report is a biased attempt to justify one site, instead of informing decisionmakers of the options," says Len Raymond of the Heritage Foundation.
"The report discounts all other options in favour of Paarl Mountain, but does not take into account the cost of infrastructure or upgrading and maintaining Jan Phillips Mountain Drive, which will carry heavy traffic during construction.
"There is also no mention of the cost of necessary mitigating efforts such as landscaping to lower the visual impact nor is there any indication as to the geotechnical feasibility of sinking the building.
"The effect of the proposal cannot be judged because no design has been presented and no detailed elevations are available.
"The impact of the building will be severe and extremely detrimental and the lighting at night will also be extremely intrusive, for which no mitigation is suggested."
Should the Drakenstein Municipal Council wish to proceed with the project, the final scoping report and a letter motivating the choice of location will be submitted to the Department of Environmental Affairs for approval, after which a period of 30 days will be allowed for appeal.
Alternatively, the Department might call for a full environmental impact assessment of the project. |
