Company Overview

By 2050, at least one in four people is likely to live in a country affected by chronic or recurring shortages of fresh water.

According to the United Nations, water scarcity, poor water quality and inadequate sanitation negatively impact food security, livelihood choices and educational opportunities for poor families across the world. Drought afflicts some of the world’s poorest countries, worsening hunger and malnutrition.

A significant amount of the available water is stored in open water reservoirs, which suffer from evaporation and a wide range of additional problems.

Neotop's mission is to decrease the evaporation of water reservoirs and save precious water while preserving its quality and reducing algae.

The company’s innovative, carefully designed and patented solution has undergone extensive testing and has been proven to save water by 70%-90%, while significantly reducing algae and decreasing water temperature by 4-10 degrees Celsius.

Neotop has already established pilots and operations in strategic regions and industries across the globe and had initial revenues in Q4 2017.
