The Lesotho Highlands Development Authority (LHDA) has called for the submission of tenders for the construction of Polihali dam and appurtenant works under Phase 2 of the multibillion-rand bi-national Lesotho Highlands Water Project.

Interested and suitably qualified tenderers have until November 12, 2021, to submit their proposals.

The Polihali dam will be a 166-m-high basalt concrete face rockfill dam (CFRD) situated on the Senqu river near the town of Mokhotlong.

The reservoir capacity will be 2 325-million cubic metres and, apart from the main dam embankment, the project includes a 43-m-high saddle dam, also CFRD; a 33-m-high upstream cofferdam; 105-m-high intake tower with a 5 m outlet tunnel/chute to release 300 m3/s; a 98-m-long ogee spillway designed to discharge 4 300 m3/s; two bridges and an outlet house incorporating compensation and flood release valves, as well as a 2 x 2.1 MW mini hydropower station.

Tender documents will be available for download or collection from the LHDA from August 9.

A virtual pre-tender meeting will be held on August 23, with a site visit scheduled on August 31.
