Lessons Learned: GIS-based drainage network mapping before rehabilitation design prevents costly mid-project design revisions and optimises pump station placement.
BALSIRA GROUP supplied a seawater desalination plant and associated distribution infrastructure to provide process and potable water to a coastal diamond mining operation with no access to freshwater sources.
Client: Namdeb Diamond Corporation
Duration: Jun 2022 – May 2023
Challenges: Extremely arid coastal environment, no freshwater within 200 km, harsh wind-blown sand affecting mechanical equipment, remote construction logistics.
Solutions: Containerized SWRO desalination plant for rapid deployment, sand-proof equipment enclosures, solar-assisted pre-heating to reduce energy consumption.
Technologies/Equipment: Containerised SWRO desalination plant, pre-treatment filters, energy recovery turbines, insulated distribution pipes, diesel-solar hybrid power supply.
Stakeholders: Namdeb mining management, Namibia Water Corporation, Department of Environment, remote site logistics team.
Budget: $6.4M
Environmental & Social Impact: Self-sufficient water supply for 1,200 mine workers, elimination of expensive long-distance water trucking, controlled brine return to sea in compliance with environmental permit.
Key Achievements: Water supply independence achieved within 11 months, trucking costs eliminated saving $1.4M annually, plant operating at 95% availability after first year.
Lessons Learned: Containerised SWRO plants are ideal for remote mining applications where speed of deployment and equipment portability are critical factors.
BALSIRA GROUP supplied carbon steel line pipe, fittings, flanges, and valves for an onshore natural gas gathering pipeline network in the Rovuma Basin gas development programme.
Client: ENI Mozambique LNG Development
Duration: Aug 2023 – Jun 2024
Challenges: High-specification API 5L pipeline material requirements, security challenges in Cabo Delgado Province, difficult tropical terrain and river crossings.
Solutions: Pre-qualified API-certified pipe mills, armoured logistics convoys for supply chain security, horizontal directional drilling for river crossings.
Technologies/Equipment: API 5L X65 line pipe, forged fittings, ball valves, flange assemblies, cathodic protection systems, pipeline coating materials.
Stakeholders: ENI project team, government of Mozambique, pipeline construction contractor, security services.
Budget: $14.7M (materials supply)
Environmental & Social Impact: Supports Mozambique's gas monetisation programme, national revenue generation potential, temporary construction employment for local workers.
Key Achievements: All materials delivered to site within security-constrained schedule, zero API non-conformance on delivered pipe, river crossings completed without environmental incidents.
Lessons Learned: Security risk management must be fully integrated into supply chain logistics planning from project inception in conflict-affected zones.
