Welmoed Reservoir
The rapid pace of migration, population expansion and urbanisation within the City of Cape Town has placed an unprecendented demand for social and affordable housing, with the Western Cape Department of Infrastructure (which now incorporates the province’s former Department of Human Settlements) forging ahead on a range of projects.
A prime example is the Welmoed Estate Development project, which issituated in Blue Downs to the east od the City of Cape Town municipal area,surrounded by the Blackheath, Eersterivier suburb, and the Stellenboschfarmlands.
The development, which makes provision for approximately 8000 Breaking New Ground (BNG) housing units within an approximately 200 ha land rack, is divided into two phases, with Phase 1 further divided into three sub-phases(Phase 1A, 1B and 1C). Currently, only Phase 1A is under way, entailing the construction of 1348 BNG units, together with supporting civil and electrical engineering services, as well as bulk services.
