Our programme · Bangladesh

Building Water Business turns safe water and sanitation into a working market, supporting local entrepreneurs in the southwest coastal districts of Bangladesh to build and sell the latrines, handwashing devices and services that families want, and will pay for.

The challenge
Safe sanitation shouldn’tdepend on aid

In the flood-prone districts of southwest Bangladesh, unsafe sanitation and poor hygiene keep diarrhoeal disease common and hold back children’s growth. Many households want better latrines, handwashing basins and clean water, but the local supply of quality products, and the finance to buy them, has been missing.

Where services are handed out for free, they tend to disappear when the funding does. The more durable question is whether a real market can meet this need: entrepreneurs who can supply and maintain WASH products at a fair price, and households willing to invest in them.

How the programme works
Strengthening supply,creating demand

Building Water Business works on three fronts at once: a stronger private sector, integrated awareness and demand, and a supportive government and community environment. Local entrepreneurs build and sell latrines, handwashing basins and women’s bathing chambers; health-promotion agents sell hygiene and nutrition products on commission; and a cadre of sweepers empties pit latrines as a paid service.

A stronger private sector
Entrepreneurs are supported to produce, sell and maintain WASH products profitably, and to form associations that negotiate together with suppliers and local government, giving small businesses collective weight and staying power.
Awareness and demand
Social marketing and community engagement help families understand why safe sanitation and hygiene matter, turning need into genuine demand that a market can respond to.
An enabling environment
Working with government departments and community institutions creates the conditions, standards and coordination a private WASH market needs to grow and last.
Women in business
Women are supported to lead as entrepreneurs and agents, building incomes of their own while widening who a water and sanitation market reaches.

Markets as the engine
Proof that WASHcan pay for itself

When a latrine or handwashing basin is something a local business profits from selling, supply keeps flowing without subsidy. In 2025 entrepreneurs grew turnover by around a quarter and most extended their product ranges, signs of a market maturing rather than a project being delivered. That commercial durability is what allows access to continue after external support tapers.
