A 2019 report by the Sanitation Technology Platform (STeP) investigates the question of sustainable business models for community and public toilets (CPTs) in India. Sparse evidence of sustainable CPT business models limits the sector’s knowledge of how business model innovation could transform the future of CPTs in India. Multiple organizations — five of which are featured in this report — are actively innovating their business models to address persistent challenges. Case studies from other sectors – including water, renewable energy, and agriculture – show how similar challenges are being tackled with business model innovations for other base-of-pyramid markets. These organizational examples offer important lessons and inspiration for the sanitation sector in India and other contexts that rely heavily on shared sanitation infrastructure.
