Botswana WUC

Botswana Water Utilities Corporation (WUC) has identified a need to refurbish the North South Carrier 1 (NSC-1) Pump Stations PS 1.1 (Tender WUC013 of 2017) and PS 2.1(Tender WUC013 of 2017) to enhance efficiency. The main objectives are to upgrade and refurbish the Pump stations in order to provide required water outputs to BPT1A1 and BPT2A1, respectively. Pump station PS1.1 is situated at Letsibogo dam, while Pump Station PS2.1 is situated approximately 32.6km downstream from Letsibogo dam, at Moralane, together with Break Pressure Tank 1 (BPT1A1). Both pump stations are currently running with Constant Speed Drive Pumps. One of the activities embedded in the upgrade and refurbishment of the two pump stations is to change from Constant Speed Drive Pumps (Roto-Starter) to Variable Speed Drive (VSD) Pumps. For correct and accurate VSD pump selection, good understanding of the condition of the current NSC-1 pipeline system, working in synergy with the two pump stations is required.

This scope of works cover general requirements for assessment, supply, delivery and installation of Mechanical, Civil, Electrical, Control Equipment, Instrumentation Equipment, Actuators, Associated Accessories, and documentation (drawings and manuals). This project covers all equipment in the Pump Stations, including modification of the suction and delivery pipe work and construction of a building to house Variable Speed drive units. The second requirement is for the Scheme SCADA upgrade, engineering and configuration to cater for all changes which have been effected at the pump station to allow for monitoring, control, data acquisition and automation in order to enhance operational efficiency of the scheme.

Khato Civils / NTR Technology Holdings JV (KCNTRJV) having demonstrated in their tender proposals that they have the technical, financial and managerial skills to complete the Contracts successfully was appointed on an EPC basis by the Water Utilities Corporation (WUC) of Botswana on 16 February 2018 for the refurbishment of Pump Stations PS1.1 and PS2.1 located on the North-South Carrier 1 pipeline. The Contracts valued at BWP 101,767,567.33 and BWP 93,451,640.26 are running simultaneous and must be completed within 15 months ending on 12th August 2019.
