Complete research and development process since 2017: Please refer to the project entry "Mobile Dry Diversion Toilet" on this website

After years of development, field tests, and the careful evaluation of the (female) users' feedback, we feel ready for the roll-out of 50 MDDTs to 50 women and their households in low-income communities in Lagos, Nigeria. In July 2024, we handed over 10 MDDTS to their female owners. It’s the first tranche of the 50 pieces-roll-out.

In this project phase, the women owners pay half of the cost price, by small weekly rates during one year, the other half of the cost price is donated by a Swiss foundation. Including the 21 pcs. from the previous field trials, there are now in total 31 MDDTs in operation. It’s beautiful to see how these small blue towers are popping up in the beneficiary communities, providing the women and their households with the badly needed basic sanitation.

FABULOUS URBAN personnel continues to monitor all the 31 MDDTs on a weekly base. Usually, the sacks (feces) in the barrels are exchanged once a week, the cans (urine) are emptied every 2 to 5 days. The feces are sold to farmers against a token, generating a small income for the households, or they are directly used by the women in their own gardens.

MDDT is on purpose a household toilet, providing safety, security, comfort for the women and their households during day and night. There is no longer a need of long, insecure, and unlit walks to unsafely managed community toilets, or of the use of throwaway bottles or sacks (open defecation).

MDDT is easily to dismantle in the case of forced evictions.

The squatting pans are industrially manufactured (deep drawing technology) and are currently produced in Germany. However, the mold allows now for worldwide manufacturing (see project entry "Mobile Dry Diversion Toilet" on this website).
