Sierra Leone sanitation: understand the system before trying to fix it.

Sanitation is not one problem. It includes toilets and hygiene, solid and liquid waste, collection systems, drainage, public behaviour, environmental leakage, service-provider capacity and the institutions responsible for each part. This page brings reliable sources and practical questions together in one place.

Start with the definition

Sanitation is wider than waste collection.

In public discussion, “sanitation” can refer to very different systems. WASH programmes focus on water, toilets, hygiene and safe management of human waste. City sanitation also includes solid and liquid waste collection, street cleanliness, drainage and disposal. Coastal sanitation adds another layer: preventing waste and contaminated runoff from reaching beaches, creeks, wetlands and the sea.

Those systems overlap, but they are not interchangeable. A credible sanitation strategy needs to identify the specific problem, the responsible authority, the operating gap and the evidence needed before choosing an intervention.

Current national context: UNICEF Sierra Leone's WASH overview reports continuing large gaps in basic sanitation and hygiene access. The figures should be read with their source definitions and reporting period rather than mixed with older survey numbers.

Freetown today

The collection architecture matters.

Any project working on waste in Freetown needs to fit the city's current legal and service-provider system.

Current rule

Approved providers hold the collection mandate.

Freetown City Council states that the 2024 Solid & Liquid Waste Collection Byelaws are in force and that approved service providers have the legal mandate for collection across the city's 8 blocks and 48 wards.

Local routing

Each block has a designated provider.

FCC publishes the current providers, wards and communities they serve. This is essential when evaluating where YSI can add evidence, interception, recovery or community-value functions without duplicating authorized collection.

Public behaviour

Collection only works when disposal behaviour works.

FCC's sanitation rules also address registration, scheduled collection and illegal dumping or burning. Infrastructure, enforcement, incentives and community behaviour therefore have to be considered together.

National WASH

Toilets, hygiene and waste are connected public-health systems.

UNICEF's Sierra Leone programme frames sanitation alongside safe water, hygiene, climate resilience, schools, health facilities and community systems—useful context when waste and environmental conditions affect health and dignity.

The practical evidence agenda

What should be measured before a new solution is proposed?

YSI's approach is to turn a broad sanitation problem into answerable operating questions. For solid-waste and coastal-leakage work, the first job is not to choose machinery. It is to understand the stream, route and failure point.

01
Where does waste escape the existing system?Identify leakage points, timing, geography and the pathway into streets, drains, beaches, creeks or wetlands.
02
What is actually in the waste stream?Weigh and characterize material instead of assuming the proportions of plastics, organics, glass, metals, paper and residuals.
03
Which materials have a real downstream route?Recovery only counts when quality, volume, storage, transport and buyer requirements are understood.
04
Which gap belongs to whom?Separate city collection responsibilities from community behaviour, environmental interception, recovery, drainage, enforcement and technical-development needs.
05
What does the intervention cost per useful outcome?Track labour, transport, storage, sorting, rejects and destination costs so expansion decisions are based on evidence.

YSI's role

Build around the system—not around a claim to replace it.

YSI Africa is not positioning itself as Freetown's official municipal waste collector. Its current development work focuses on practical evidence, localized environmental leakage, characterization, recovery testing, community participation and system improvement within the applicable authority structure.

MEASUREGenerate defensible field evidence on waste streams and leakage.
CHARACTERIZEUnderstand material composition, contamination and recoverability.
TESTEvaluate realistic recovery, routing and data-collection methods.
CONNECTWork with authorities, service providers, communities and technical experts where roles align.

Source library

Use primary and institutional sources first.

YSI is building this page as a living public reference. Where sources disagree or use different definitions, the difference should be explained rather than hidden.
