Proposed Langkloof Dam and Associated Infrastructure, Near Worcester, Western Cape Province

PROPOSED LANGKLOOF DAM AND ASSOCIATED INFRASTRUCTURE, NEAR WORCESTER, WESTERN CAPE PROVINCE: PUBLIC PARTICIPATION PROCESS: NOTIFICATION OF SUBMISSION OF THE APPLICATION FOR ENVIRONMENTAL AUTHORISATION, AND AVAILABLITY OF THE DRAFT SCOPING REPORT (INCLUDING A COPY OF THE INTEGRATED WATER USE LICENCE APPLICATION) FOR COMMENT

SCOPING AND ENVIRONMENTAL IMPACT REPORTING PROCESS:

DEA&DP Pre-Application Ref No.: 16/3/3/6/7/1/B2/32/1095/20

Heritage Western Cape Ref No.: 19080607AS0214E

Department of Water & Sanitation WULA Ref: WU20475

The Worcester East Water Users Association (WEWUA) proposes to construct a new dam (i.e. the Langkloof Dam) and associated infrastructure, on Portion 1 of Farm Lang Kloof No. 322 as well as Portion 22 and Remainder of Portion 4 of Farm Twee Fonteinen No. 319, approximately 8km north east of Worcester, within the Breede Valley Municipality in the Western Cape Province.

The proposed project, including associated infrastructure, includes the following:

  • A new dam (the proposed Langkloof Dam), with a maximum storage capacity of
    2.40 Mm3, maximum dam wall height of approximately 36m, and water surface area at Full Supply Level (FSL) of approximately 16.50ha.
  • Proposed new water pipeline, from the proposed Langkloof Dam to the existing Boskloof pipeline. The proposed pipeline would have a diameter of 400mm and would be approximately 1.6km in length.
  • Re-alignment of a section of an existing gravel farm road that would be located within the FSL of the proposed Langkloof Dam, to above the proposed dam basin.

The Worcester East Water Users Association’s current water distribution scheme is entirely reliant on pumping to distribute water (i.e. the water distribution scheme currently functions by pumping water from the Breede River into several balancing dams which supply the surrounding agricultural areas). There are currently no contingency measures in place which would allow for irrigation in the event where the system experiences “down-time”, which could be caused by a lack of power (e.g. load shedding) or a pump malfunction. According to Zutari (previously known as Aurecon South Africa (Pty) Ltd), the consulting engineers for the project, the main need for the proposed project is to provide emergency gravity storage (of water) for the system in the event of power failures, to increase assurance of water supply to the crops for the members of the WEWUA, as well as to possibly irrigate certain areas under gravity.

In terms of the Environmental Impact Assessment (EIA) Regulations (2014), as amended, enacted in terms of the National Environmental Management Act (NEMA) (Act No. 107 of 1998), as amended, the proposed project triggers a number of listed activities identified in Government Notices (GN) R983, R984 and R985, as amended. Accordingly, the proposed activities require Environmental Authorisation from the competent environmental authority, viz. the Department of Environmental Affairs and Development Planning (DEA&DP) via the Scoping and Environmental Impact Reporting process outlined in GN No. R982, as amended.

Holland & Associates Environmental Consultants has been appointed by the WEWUA to undertake the requisite EIA process for the proposed project (in this case, a Scoping and Environmental Impact Reporting (S&EIR) process) in accordance with the NEMA (Act No. 107 of 1998), as amended, EIA Regulations (2014), as amended.

Notice is given of the submission of the Application for Environmental Authorisation to DEA&DP, in terms of the NEMA EIA Regulations (2014), as amended, in respect of the proposed project. Furthermore, notice is given of the availability of the Draft Scoping Report for I&AP review and comment.

The Draft Scoping Report (including a copy of the Water Use License Application (WULA)) has been made available to the public for review for a 30 day comment period, and is downloadable via the link below. Registered Interested & Affected Parties (I&APs) have 30 days, i.e. 8 July 2021 – 10 August 2021 to submit comments related to the proposed project and the aforementioned documents. Any comments received from I&APs will be collated and responded to in a Comments and Response Report CRR(2), and will be included in the Final Scoping Report that will be submitted to DEA&DP at the end of the Scoping Phase. The CRR2 will also be included in the draft Environmental Impact Assessment (EIA) Report that will be circulated for I&AP comment in Phase 3 of the EIA process. All registered I&APs will be notified when the draft EIA Report (in Phase 3 of the Scoping & Environmental Impact Reporting process) is available for comment.

Should you have any comments, issues or concerns regarding the proposed project or the findings of the Draft Scoping Report, please provide your comments in writing to Kelli Ross of Holland & Associates Environmental Consultants, by email, fax or post (Fax: 086 762 6126, email: kelli@hollandandassociates.net or post: PO Box 31108, Tokai, 7966), on or before 10 August 2021.
