Project Sammaan facilities are uniquely designed, prioritizing the user experience to ensure that people actually want to use community toilet facilities. These facilities feature large ventilation openings allowing for more natural light and adequate air circulation. Gender-segregated latrine stalls and internal circulating spaces are also larger allowing for greater user comfort and mobility. Universal Access stalls have been provided to cater to individuals who are differently-abled, elderly and pregnant.  Each facility also has a dedicated bore well ensuring access to sufficient water, and a standalone septic tank systems with the option to connect to city septic lines when they extend to cover project sites.

Project Samman facility design is an effort to address some of the common complaints of community toilet users that facilities are too dark, cramped, and malodorous. The facilities also feature a cohesive branding strategy for signage, uniforms and stationary to reinforce the concepts of professionalism and dignity in community sanitation. The underlying principles for these designs were derived from an in-depth ethnographic study, called the Potty Project, which was conducted across 5 cities in India. More details may be found in the Potty Project Brief in the Resources page or on

There are three categories of Project Sammaan facilities:

  1. Very Small Two Seaters (VS2WC) – Gender segregated entry, latrine stalls, caretaker booth, hand and foot wash, and child potties
  2. Base Layer – Gender segregated entry, latrine stalls, caretaker booth, hand and foot wash, clothes washing spaces, child potties, universal access stall, utility rooms
  3. Enhanced Layer – All Base Layer amenities plus bathing stalls and on-site shop spaces.

Additionally, all facilities with greater than 6 latrine stalls have an upstairs caretaker’s quarter.

Across these three categories, there are 13 different Project Sammaan facility typologies each with its own number of latrine stalls and sanitation-related amenities. Allocation of particular typologies to project sites is based on a number of factors, including land availability, estimated potential demand and budgetary constraints.
