Stage 3: Proof of Concept
The Flexcrevator team is currently testing prototypes in Kenya and Lusaka. We will then partner with manufacturers on the African continent to create a small scale manufacturing run. The initial units will prepare us for our transition to scale.

Funds Raised to Date
Nearly two billion people on earth use pit latrines as the primary way to defecate and urinate. Pit latrines fill up quickly with human waste and large amounts of trash including rags, plastic bags, bottles, and hair. People often remove waste manually, exposing workers to a host of human pathogens without sufficient protection. While mechanized ways to remove fecal sludge such as vacuum trucks exist, these devices are expensive and clog from high volumes of garbage.
The Flexcrevator is a portable vacuum system coupled with a trash excluding attachment. Our unique device aspirates fecal sludge while simultaneously leaves trash in pits. By separating fecal sludge from trash during operation, we reduce the risk of jamming in the vacuum hoses. This makes the overall process of emptying more sanitary and hygienic. If the pit latrine emptier already has access to a vacuum truck, they have the option of pairing it with the trash excluder alone.
Our pit emptying device serves low and medium-income countries in Asia, Africa, South and Central America. Possible customers include small scale entrepreneurs, sanitation entrepreneurs, cities (such as Lusaka, Zambia or Blantyre, Malawi, among others), development agencies, international donor agencies (such as GIZ, The Red Cross). The number of people affected by the technology would be in the billions, who currently pay for pit emptying every six months or every 1-4 years.
Mission and Vision
Manual emptying of pit latrines using buckets and shovels is is a high-risk, unsanitary, and undignified job that should not exist today. The presence of large amounts of trash, and access to and within the pit are crucial barriers to development of a single pit emptying technology that can empty a high percentage of pits at a competitive cost. We aim to overcome these barriers, improve existing sanitation practices, and dignify pit emptying work worldwide through our low cost technology.
The Flexcrevator surpasses manual emptying by providing a safe, hygienic process for workers. When using the Flexcrevator, pit latrine emptiers have less opportunities for direct contact with raw fecal sludge. Our unit has competitive advantages over vacuum trucks as its small, modular, footprint allows workers access to pit latrines in narrow alleyways that usually restrict vacuum truck access. In terms of price point, the overall device is 10-20x cheaper than a vacuum truck. Unit's cost is nearly 50x cheaper than the standard vacuum truck under commercial production levels. While vacuum trucks are typically imported into developing regions, we designed the Flexcrevator with local manufacturing and sourcing in mind, allowing for lower maintenance costs. Finally, if a vacuum truck operator uses a trash excluder on an existing truck, the operator gets a competitive advantage over other truck operators as our excluder opens new business opportunities to empty trash filled pit latrines.
Planned Goals and Milestones
We strive to create the most hygienic product and process possible; we will incorporate new storage and safety features to further reduce fecal sludge exposure risk during operations and storage. We also will redesign the device to improve ergonomics to ensure that operators work in comfortable conditions. Finally, to reduce cost and weight of the overall unit, we will explore how to drive the unit using a gas engine.
