Advancing the Sanitation Economy Infrastructure Partners

Our vision

Our vision

By 2030, ASE INFRA aspires to be a key player in the segment of decentralised sanitation economy infrastructure in emerging markets.

ASE INFRA will achieve this position through the acquisition, construction and optimisation of sanitation infrastructure assets.

In expanding its portfolio, ASE INFRA takes advantage of opportunities offered by the current and emerging trends towards decentralised sanitation infrastructure.

We have the ambitious goal to grow and expand decentralised sanitation solutions in emerging markets by separating assets from operators, and enabling increased investment into the sector, by applying a proven asset management investment model from the renewable energy sector.


Decentralised sanitation solutions are essential for the development of low-income economies and the protection of water quality, quantity, human health, dignity and well-being.  Decentralised sanitation infrastructure is a more affordable and sustainable alternative.





We invest in

decentralised sanitation economy infrastructure

in emerging markets

Our impact:


  • resilient access to sanitation for more people, 

  • more sewage and wastewater treatment which will result in improved water quality and water quantity through reuse, 

  • more efficiency and reliability through the use of digital technologies

Growth stage companies ready to scale sanitation infrastructure including: 


  • public toilet and sanitation centres;

  • sewage and wastewater treatment plants (STP/FSTP); and

  • digital/smart sanitation infrastructure


Our investments will help to professionalise the sanitation sector by making sanitation companies asset light to enable faster expansion, with sustainable business models.
