About us

Efcon® Water is specialized in the development & production of stationary wastewater samplers and the integration of these samplers in wastewater billing installations. Nowadays our knowledge and products are applied from Brasil to Tasmania. The main market is Europe.

In order to meet the customer demand for strong and chemical resistant enclosures, Efcon® Water introduced a new production procedure for thermoplastic cabinets. It soon became clear that this material offered superior advantages over conventional steel products and it increased the sales for our patented enclosures significantly. Today most competitors follow in applying plastics. They follow, Efcon® leads.

In addition to qualitative enclosures, our customers also wish to choose from various sampling techniques, worldwide applied electronics and optional equipment such as Electro Magnetic Flowmeters, Wastewater Pumps & Pits, Water Levels Sensors etc. In these areas Efcon® built a complete product range.
