Environmental Protection & Public Health
NAWEC manages sewerage collection and treatment services across served areas of The Gambia. Proper wastewater management is essential for public health, environmental protection, and the sustainable development of urban communities.
NAWEC's sewerage division operates collection networks and treatment facilities, ensuring wastewater is safely collected, treated, and disposed of in compliance with environmental standards. Ongoing infrastructure investments are expanding and modernising the sewerage system.
Collection Networks
NAWEC operates sewerage collection networks that transport wastewater from connected properties to treatment facilities.
- Gravity Sewers — Underground pipe networks using natural gradients to convey wastewater
- Pumping Stations — Lift stations that move wastewater where gravity flow is insufficient
- Manholes & Access Points — Inspection and maintenance access across the network
- Property Connections — Individual connections linking properties to the main sewer lines
Treatment Facilities
Wastewater treatment facilities ensure that sewage is properly processed before safe discharge into the environment.
- Primary Treatment — Physical removal of solids and sediment from wastewater
- Secondary Treatment — Biological processes to break down organic matter
- Effluent Discharge — Treated water safely returned to the environment
- Sludge Management — Proper handling and disposal of treatment by-products
Environmental Compliance
NAWEC ensures all sewerage operations meet national environmental standards and international best practices.
- Effluent Monitoring — Regular testing of treated discharge to verify quality standards
- Environmental Audits — Periodic assessments of environmental impact and compliance
- NEA Coordination — Working with the National Environment Agency on standards
- Reporting — Transparent reporting on environmental performance and compliance
