The Durasan latrine is a modular toilet stall constructed with either a pit or flush toilet.
Durasan latrines are modular stalls constructed with prefabricated interlocking concrete blocks. The latrines are serviced by Sanitation Solutions Group for maintenance and periodic emptying to allow for prolonged functionality. The toilets are scaled to the community and family level, and are afforded through microfinance loans.

Alternatives include non-emptied pit latrines and toilets connected to septic tanks.
Goal 6: Clean water and sanitation
The Sustainable Sanitation Group targets families and communities in urban Uganda with a system of sanitation services ranging from latrine construction to waste collection and treatment.
Concrete blocks are cast similar to puzzle pieces that can be interlocked to create the latrine structure. A door frame, door and concrete roof is then attached to create the modular toilet. The goal of this building method is to simplify the construction process to the point that customers can assemble the product themselves.
The manufacturers at Sanitation Solutions Group work with microfinance institutions to help customers obtain sanitation loans. This sanitation system aims to reduce problems related to construction workmanship and delays by marketing a prefabricated product complete with waste-collection services for urban consumers in Uganda. If users are not able to repay their loans, the manufacturer will retrieve the structure.

The Durasan latrine was designed to be constructed without the need for skilled masons. The interlocking concrete blocks were designed to fit like legos to enable easy construction, and the sanitation system was designed to integrate latrine construction, upgrading and maintenance to ensure continual functionality.
Support in constructing and maintaining the latrine is provided by the manufacturer.
Components can be replaced with local materials.
25 years interview with designer
The manufacturer aims to expand their company to 200 employees by creating a franchise in each region in Uganda. This will be achieved by training entrepreneurs to sell and produce the latrines, with an ultimate target of obtaining 20 outlets by 2020 and then partner with organizations in Kenya and South Sudan.
Possible hazards include unsanitary latrine emptying or structural failure.
The Durasan latrine is one component of a system of sanitation technology and service provided by the Sanitation Services Group. In addition to latrine construction and installation the group provides maintenance (related to slab repair, cleaning and latrine upgrading) and assists in continual operation with pit and tank emptying.
The latrines are inspected visually by members of the Sanitation Solutions Group for damages and structural integrity.
