What our clients say

It is a pleasure to endorse and recommend the services provided by Venturi Systems SA (PTY) LTD. We required the installation of an integrated and sustainable system for water conservation and sterilisation and for solar energy for a property on the South Coast. Thomas Els from Venturi Systems provided us with a comprehensive conceptualisation of the project and efficient and effective project management from start to finish, including the sourcing and oversight of specialist sub-contractors and the procurement of components. Throughout the project, Thomas was mindful of the need to control costs, ensuring value for money. As a result, we now have a water supply that protects us from pollution and service breaks in the municipal water supply, as well mitigating the effects of future droughts. We also have a reliable supply of renewable energy that is sufficient for at least six hours of power outages a day.
