If construction was the first mile, behaviour change is the last — and it’s the mile most CSR sanitation programmes still under-invest in. The evidence from villages that have sustained ODF status (not just declared it once) points to a consistent pattern: toilets that come bundled with sustained community engagement, trained local champions, school-based hygiene education, and functioning water supply outperform toilets that arrive as a one-time construction grant.

For corporates funding sanitation under CSR mandates, this reframes the metric of success. “Number of toilets built” is an easy number to report and a poor proxy for impact. The more meaningful — if harder to capture — metrics are usage rates six months and two years post-construction, faecal sludge management coverage, and measurable reduction in water contamination in the surrounding area. CSR capital is uniquely positioned to fund the unglamorous middle: community sanitation workers, IEC (information, education, communication) campaigns, and monitoring systems, because these rarely attract the same political or media attention that a toilet inauguration does.

Why CSR Is Positioned Differently Than Government Programmes

Government sanitation missions operate at a scale and on timelines that make construction targets almost unavoidable — a national mission needs a number to rally behind, and toilet counts are that number. CSR capital doesn’t carry the same pressure. It’s smaller, more flexible, and typically tied to a company’s own long-term reputation and relationship with the communities it operates in, rather than an election cycle or a mission deadline.

That difference in incentive structure is CSR’s real advantage. A corporate funder can choose to measure success two or three years out instead of at the point of handover. It can fund a district-level behaviour-change campaign that has no ribbon to cut. It can pay for the ongoing salary of a community sanitation worker whose job is unglamorous, recurring, and essential — the kind of budget line that a large public programme’s audit structure often struggles to accommodate. In short, CSR can fund the parts of the sanitation chain that produce outcomes rather than announcements.

What a Behaviour-Change-First CSR Model Looks Like

Fund the follow-through, not just the fixture. Instead of a grant that ends when the toilet is built, structure funding to cover 18–24 months of post-construction engagement: household visits, usage tracking, and rapid repair support when something breaks. A toilet that stops working within its first year and is never fixed effectively reverts the household to open defecation — repair funding is sanitation funding.

Train and pay local behaviour-change champions. The most durable shifts in practice tend to come from trusted community voices — often women’s self-help groups, ASHA workers, or local youth — repeatedly and patiently making the case for usage, not from outside agencies parachuting in for a campaign week. CSR programmes that fund and formally train these champions, and keep them engaged over multiple years, see stickier results than those that fund a single awareness drive.

Treat water access as part of the sanitation budget, not a separate line item. A toilet without water is a structure waiting to be abandoned. Any CSR sanitation investment should audit water availability at the outset and fund the gap — whether that’s a borewell, a connection to existing supply, or a rainwater harvesting system — as part of the same project, not a future phase that may never get funded.

Invest in safe faecal sludge management, especially where mechanised systems don’t reach. In many rural and peri-urban areas, pits still need manual or semi-mechanised emptying, and this is where the greatest health risk — to both groundwater and the workers involved — concentrates. CSR funding for safe, dignified desludging services, and for protective equipment and training where manual involvement is unavoidable, addresses a link in the chain that almost no one else is funding.

Measure and report what actually matters. Shift CSR impact reporting away from “toilets constructed” and toward usage rates, functional status at 12 and 24 months, water quality testing near sanitation sites, and reduction in water-borne illness in the target population. These are harder numbers to gather — they require repeat surveys and sometimes third-party verification — but they are the numbers that tell you whether the money produced health outcomes or just structures.

The Business Case, Not Just the Moral One

For companies weighing where to direct CSR sanitation spend, there’s a practical argument alongside the ethical one: behaviour-change-first programmes are more defensible under increasing ESG and CSR-impact scrutiny. Reporting frameworks are moving toward outcome-based metrics, and a portfolio of “toilets built” numbers is increasingly seen as a thin, first-generation form of impact reporting. Funders who can show sustained usage data, water quality improvement, and health outcome shifts are better positioned for both regulatory reporting and genuine reputational credibility — the kind that isn’t undone by a follow-up survey finding half the toilets unused.

Closing the Gap Is a Choice, Not an Inevitability

None of this requires new technology or radical redesign. It requires funders willing to measure success later, fund less visible line items, and stay engaged with a community well past the point where a photograph could be taken. CSR is one of the few pools of sanitation capital flexible enough to do exactly that. The question for any corporate funder entering this space now isn’t whether toilets are needed — it’s whether they’re willing to fund what happens after the toilet is built. That’s where sanitation actually happens.
