Informal Settlement Upgrading and Metropolitan Drainage Engineering in Zanzibar

Programme Overview

Rapid urbanisation across East African coastal regions has led to the proliferation of informal settlements situated within flood-prone, low-lying basins.⁣​‌​‌​​‌​​‌‌​‌​‌‌​‌‌‌​​‌‌​‌‌‌​​‌​​​‌​‌‌‌​​​‌‌​​​‌​‌‌‌‌​​​​‌‌​‌​​‌⁣ This five-day course equips technical professionals with advanced capabilities in sustainable stormwater drainage engineering, flood mitigation, and inclusive settlement regularisation. Hosted in Zanzibar, the programme bridges civil engineering interventions and metropolitan spatial planning, offering participants actionable approaches to design resilient primary, secondary, and tertiary infrastructure that withstands intense tropical precipitation, tidal influence, and severe climate vulnerabilities characteristic of coastal zones.

Engineers and municipal planners must coordinate across technical, environmental, and social domains to prevent disaster risks in high-density unplanned settlements. The curriculum covers the application of current hydrodynamic modelling tools, hydrologic calculation methods, and nature-based sustainable drainage systems (SuDS) aligned with international standards. Participants will evaluate engineering solutions for coastal outfalls, detention facilities, and non-structural flood plain management while examining socio-economic frameworks necessary to integrate existing settlements smoothly into the wider metropolitan infrastructure network without causing undue displacement.

Through intensive case analyses, site visits in Zanzibar, and practical design studios, participants develop tailored interventions that balance technical feasibility with community needs. The syllabus is structured to reflect the engineering and urban regeneration safeguards mandated by multilateral development banks, including the World Bank Environmental and Social Framework. By concluding with applied group design sessions, the training ensures participants return to their institutions equipped to formulate bankable, climate-resilient infrastructure investments that enhance public health and municipal urban resilience.

Coastal urban centres across East Africa face severe seasonal inundation and expanding informal settlements that outstrip municipal infrastructure capacity.⁣​‌​‌​​‌​​‌‌​‌​‌‌​‌‌‌​​‌‌​‌‌‌​​‌​​​‌​‌‌‌​​​‌‌​​​‌​‌‌‌‌​​​​‌‌​‌​​‌⁣ Large-scale urban regeneration programmes, such as the Dar es Salaam Metropolitan Development Project Phase 2, underscore the urgent imperative to combine trunk drainage engineering with community-level settlement regularisation. Municipalities require upgraded institutional competencies to execute multi-sectoral works involving complex coastal outfalls, retention basins, and basic service integration within challenging urban fabrics to safeguard vulnerable populations and critical urban economic assets.

Delivered by Risalat Consultants International in Zanzibar, Tanzania, it combines expert-led sessions, real cases and group work, so that participants can apply what they learn in their own institution.

It is designed for municipal and city civil engineers, urban and regional physical planners, environmental and social safeguards project officers and others who want practical, current skills in environmental, social and stakeholder management.

The Growing Importance of Informal Settlement Upgrading and Metropolitan Drainage Engineering in Zanzibar

Financiers now require projects to identify and manage environmental and social risks from the start, and to involve the people affected. Weak safeguards management causes delays, suspended disbursements and lasting harm to communities.

Good practice in stakeholder engagement, grievance handling, inclusion and resettlement protects people and keeps projects on track. Teams who understand the standards and apply them early save time and build trust.

Organisations increasingly require professionals capable of:

• Screen and classify environmental and social risks
• Prepare and implement management plans
• Engage stakeholders meaningfully throughout the project
• Run grievance mechanisms that resolve issues
• Monitor and report on commitments to financiers

Strong environmental, social and stakeholder management systems help organisations:

• Avoid delays and suspended disbursements
• Protect communities and workers
• Meet financier standards and commitments
• Build trust with affected people and the public

This Informal Settlement Upgrading and Metropolitan Drainage Engineering in Zanzibar programme brings these elements together in a practical format, so that participants understand not only what good practice looks like but also how to introduce it in their own setting, with the people and resources they have.
