Water supply system plays an important role in ensuring water quality, pollution reduction and controling the spread of waterborne diseases, thereby ensuring the development of sustainable shrimp farming. Though the shrimp farming in Northern coastal areas has been growing rapidly, the survey of the Institute for Agricultural Environment (IAE) showed that water supply and drainage system for aquaculture can not response to the requirement with adequate investment, and largely depended on agricultural irrigation systems. This system, though, has been invested for upgrading but still not a priority focus on the design and supply of water for aquaculture. It seems to be designed in the direction of serving agricultural production. Aquaculture activities are largely spontaneous and many farm has only one water channel for both supply and drainage, so, it is difficult to control water quality. Water environment in the ponds is of inadequate control (baby shrimp, food, chemicals, antibiotics, microbiology), leading to water contaminated, shrimp health reduced, disease outbreaks.
