Project Background Intensive fish and shrimp farming today is under heavy pressure to produce maximum harvest biomass on limited land. To meet this challenge, the circular pond system lined with a circular pond geomembrane has become a favorite among modern farmers. The round design allows the hydrodynamics, or water circulation, to work far better than […]

Problem Background: An Invisible Threat to the Water Tank This project is located in a strategic area of Tangerang that needed a large-capacity water reservoir dedicated to its hydrant system. Building an open or semi-open water storage tank in direct contact with the soil carries a high risk, because soil has a certain permeability (ability […]

Project Background: The Classic Challenge of an Embung (Small Retention Reservoir) This project is located in Cianjur, West Java, an area that relies heavily on water availability for agriculture and plantations. The main need was to build an embung, or retention pond, that could hold as much rainwater and surface runoff as possible, making a […]
