The Ministry of Natural Resources, The Kingdom of Lesotho (hereinafter referred to as “the Borrower”) has received a loan from the European Investment Bank – EIB (hereinafter referred to as “the Bank”) – towards the cost of the Lesotho Lowlands Water Development Project (LLWDP-II). This International Invitation for Tenders/Proposals relates to the contract for LLWDP/W22. Design and Build of Ts’ehlanyane Adit Water Release Works – Leribe District.

This contract will include:

  1. The refurbishment, reinstalment and testing of an existing DN600 butterfly shut-off valve at the Adit cone face.
    1. The supply and installation of a new DN600 needle valve complete with anti-cavitation and flow regulation mechanism at the adit, just after the existing butterfly valve.
    1. The supply and installation of a DN 600 flow meter on the adit offtake with facility to transmit the cumulative water release data to the Ha Setene WTP and the LHDA offices.
    1. The detail design of the proposed steel/or any other suitable material Tśehlanyane pipeline with the capacity to transfer a maximum of 1.70 m3/s to be constructed from the Katse supply line, ± 1 855 meters inside a tunnel of ± 6-meter diameter. Outside the tunnel, the water will be transported in an open concrete channel of ± 40 meters length to the upper catchment stream of the Hlotse River. (The Contractor should take note that if steel is chosen for the pipeline, it must be completely isolated from the LHDA upstream infrastructure, to prevent spreading of corrosion and appropriate cathodic protection measures must be implemented.)
    1. The construction of the above a pipeline, should be such that the pipe is buried for the first ± 1 000 m within the centre of the ± 6-meter diameter tunnel and thereafter transferred to the extreme side of the tunnel. The pipe will then release the flow into an open channel fitted with a Parshall flume and down to a cascaded outfall into the Hlotse River. The installation of the pipeline and channel should always allow free access to the Adit.
    1. Provide electrical power for lighting the tunnel and powering the operation of the needle valve actuator and other operations including welding and grinding.

Planned Transfer Tunnel outage for completion of connections to the Katse supply line will be from 1 October 2024 to 28 February 2025.
