Opening Date – 27th September, 2020.


UN SDG 6 (2015) Clean Water + Sanitation
Ensure availability and sustainable management of water and sanitation for all by the year 2030. SDG-6 is one of the 17 Sustainable Development Goals that looks to shape human development across the ‘decade of action’.

Executive Order 009 (2019) 
President Buhari signed Executive Order 009 targeted at achieving an Open Defecation-Free Nigeria by 2025. This Executive Order enabled The Federal Ministry of Water Resources (FMoWR), the Promoter, to establish the necessary actualisation roadmap.

NIA (2020) o-DEFREN 2025
This is an Architects’ intervention in support of actualizing of SDG-6 and Executive Order 009. The Nigerian Institute of Architects (NIA) is facilitating the design of systems and solutions that are user friendly; energy efficient; socially inclusive; culturally sensitive; operated and maintained easily; utilitarian, responsive to context, attractive within the urban-scape; and that can be provided with necessary governance structure or arrangement.


The profession of Architecture is concerned with the human habitat in all its ramifications, and in Nigeria with population now numbered beyond 200million and predominantly young in demography this concern is made more acute. Formal and informal use of water will continue to outstrip supply, we must therefore deploy clear strategy for efficient and sustainable water utilisation for human and agricultural needs.
Poor sanitation as occasioned by open-air defecation (and urination) not only result in unsavoury indices in the global context, but also result in significant environmental and health challenges at a local context. o-DEFREN (open-air defection free Nigeria) seeks to tackle this dual challenge through its Toilet Design Challenge with solutions that are  sustainably domesticated and contextually responsive.


The NIA o-DEFREN 2025 Toilet Design Challenge is an open-call inviting Architects (Students and Practitioners) to submit concepts and prototype ideas that show a considered rethink of public toilets. Solutions should promote rapid prototyping and speedy deployment, clearly establish the location/cultural-context being responded to, or the targeted rural or urban situation being considered.

Use of local materials, systems, and solutions is greatly encouraged, with creativity in energy efficiency and sustainability amongst others; ultimately, they must be attractive. The Promoter seeks solutions that are able to deliver at circa NGN120,000/sqm – please note this figure includes systems, fittings, equipment, and technology.

Entries could be made as individualsteams, or firms, and there is no limit to how many submissions can be tendered under each entry. Registration is however required for each submission. This is to ensure the generation of a Unique Competition Code (UCC) for use on each submission. This invitation is fully open to students as well. Please NOTE: for administrative purposes submissions shall not be received or processed outside of this registration portal. PLEASE REGISTER HERE –

The one-month submission deadline is in line with Promoter’s established delivery schedule and roadmap, effective from the date on this Concept Note, and will not be extended. The submission deadline is 04:00pm Tuesday 27th October, 2020.

All submissions shall be electronic. Further competition information, evaluation criteria, and prize details will be displayed on the registration page.

We invite you to join in this most exciting opportunity to reshape the sanitation narrative by delivering lasting solutions that adequately respond to the SDG-6 and Executive Order 009 aspirations.
