Contaminated Watershed

The Barkese Reservoir is the main source of potable drinking water for the residents of Kumasi, the second largest city in Ghana with a population of 1,171,311. This reservoir provides 80% of the total pipe borne water to the Kumasi metropolis.

60% of Kumasi’s local food supply is grown in downstream farming communities.

Rapid population growth, institutional failures and industrial activities are all causes of pollution of the Aboabo River. The main anthropogenic causes were identified as indiscriminate dumping of refuse, channeling of raw sewage, open defecation, discharge of untreated effluents and dumping of industrial waste into the Aboabo River.


Failed Development

“Business as Usual� sewer infrastructure currently incomplete


“Leapfrogging” Investment


Existing Erosion Stream

JHS school

Flood risk endangers civic and institutional spaces


Optimum Stream


Phase 1 - Stewardship Site preparation and solid waste collection

Establish stewardship zone

Relocation strategies for flood impacted households

Flood risk impacts livability and health


Phasing 2 - Protection and Recovery Start recovery of nutrient cycles (composting begins)

Protect school through defensible landscapes

Relocation and densification strategies

Introduce ecological systems as defense mechanism


Phasing 2 - Protection and Recovery

Tree Nurseries Establish Stewardship at SchoolTraining Program: Building with Solid Waste Harvestable Trees and crops

Erosion Rehabilitation: Improved access Containment of floodable zone: Land building Water Channeling


Phasing 3 - Demonstration

Implement education and labor programs

Deploy alternative wastewater treatment and reuse strategies

Construct pediatric clinic, public toilets, and training hall

Illustrate value of on-site waste streams


Phasing 3 - Demonstration

Public Toilet: Collect Human Waste Rainwater Collection

New Roads: Improved access

Establish Stewardship at SchoolTraining Program: Building with Solid Waste Harvestable Trees and crops


Road Infrastructure

Expand access throughout site to important regional centers


Phasing 4 - Infrastructure

Develop housing typologies that support economies of waste

Develop network of transportation nodes to increase access to site

Pave critical transportation routes

Strengthen opportunity through improved infrastructure


Spatial Implications


Economies of Waste

electricity

biogas

human waste

soil/ crop clean water
