Project Overview

Sanitation in the spiritual capital of the Mouridiyya

Touba is Senegal’s second-largest city by population and the spiritual capital of the Mouride brotherhood. Every year, the Grand Magal brings together several million pilgrims, creating some of the country’s greatest sanitation needs. Tx‑H2O has deployed a System O)) specially designed to handle these exceptional volumes, with particular attention to peak periods.

The solution ensures efficient and odor-free wastewater treatment, even during major religious celebrations, while respecting the sacred nature of the site.
