NEXUS Center by Trunz Water Systems AG

Enterpreneurial Solutions for Basic Infrastructure in BOP Markets

Swiss-based Trunz Water Systems developed an innovative, entrepreneurial business concept for Bottom of the Pyramid (BoP) markets. This teaser shall provide basic information in a nutshell.




Our goal is to provide clean water and energy supply that goes far beyond a technical solution. The business model integrates local people and organisations in order to support entrepreneurship and create income. Our approach: helping people to help themselves!



The idea is to install a network of “off-grid” water and energy hubs, named NEXUS Centers, with water treatment systems and solar power centers at their core in remote areas. Due to additional revenue generation possibilities beyond safe drinking water, such as refrigeration, charging of electronic devices, space for medical treatment and small businesses, access to internet, hygiene products, etc., the NEXUS Center will become a true “one-stop” retail and infrastructure facility that aggregates community members, helps to promote local development and creates employment opportunities. The modular approach allows to tailor services and products towards the specific community needs and offers interesting partnership opportunities with telecommunication providers, micro-finance institutions and other local businesses.


Leveraging the expertise of different partners is critical to establish a successful business at the BoP. The water and energy hubs will be installed, managed and operated in collaboration with four partner entities: a local partner enterprise, an investor, Trunz Water Systems and a locally embedded NGO.

Pilot and reference projects

Since beginning of 2014, Trunz Water Systems is piloting three Nexus Centers in cooperation with several partner organizations in Nepal. The goal of the pilot is to prove the financial viability of the business concept and gather experiences for the scale-up phase. For the next phase, a thorough feasibility study including a local survey on water and energy needs and demands has already been conducted.

In addition, the concept of locally operated water shops has been implemented during the last few years within several projects in Madagascar, India, Philippines, Kenya and Pakistan.

Our Goal

We are seeking financial and strategic business support from large corporations, impact investors, philanthropic investors, family offices, private equity funds, non-governmental organizations as well as renowned international water, development and infrastructure specialists to develop and implement the NEXUS Centers on a large scale.

« As the business allows to recover investment and operational costs, it is an ideal opportunity for an investor seeking to generate beneficial social and environmental impact alongside a financial return. »





The Trunz technology will be a key component of the water and energy hubs. The innovative and environmentally friendly technology produces clean energy and safe drinking water from contaminated fresh and salt water with solar and/or wind energy. It removes all viruses, bacteria, chemical contaminants and salts without requiring toxic chemical treatment.


Trunz Water Systems AG is a Swiss-based company which develops, manufactures and distributes water purification and desalination as well as energy supply systems. The company, which was awarded with the Swiss Export Award in 2012, is dedicated to develop sustainable projects in collaboration with its partners in the following core areas: rural villages, schools, disaster relief, oil & mining, hotels, and military.
