Product Description

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.

Manufacturing/Building Method

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.

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.
