SPARC is an Indian NGO that works with communities in Mumbai to build new toilet blocks, connected to city sewers and water supplies.
The local community helps to construct the toilet and families from the community can then purchase monthly permits to use it for a very cheap price- about 25p
The SPARC toilet blocks have electric lights, making them safer to use at night, and separate toilets for children
Once they have a permit, they can use the toilet block as many times as they want during the month
Sparc has provided 6400 toilets to Mumbai in total in the past 5 years
