Water Management

Agricultural Water Management

Agricultural water management includes the management of water used in crop production, livestock production and inland fisheries. The world will need double the quantity of food in 2050, while the agricultural land is shrinking everywhere. Increased production and productivity require tools and technologies to manage the efficient use of water. From sprinkler irrigation to wick irrigation, the water conservatory practices are attaining more importance every day.

Aquaculture

In intensive commercial aquaculture operations, the sources of wastewater are primarily from uneaten food and fish faeces. The principal treatments of wastewater involve solids removal, ammonia oxidation, aeration and disinfection. Intensive systems like recirculation aquaculture is being popularised where treatment and recirculation of water is a key process.

Rainwater Harvesting

Rainwater harvesting systems are increasingly popular and important to human sustenance particularly in the wake of climate change. Given that rainfall is sporadic and that only a small proportion of precipitation is available for direct use, it can be an efficient means of capturing quality water. Basic and necessary treatment systems including filtration and disinfection shall be included in all applications of rainwater as it is stored for long periods of time.

Pond and Lake Bioremediation

Excess nitrogen, ammonia or phosphorous build-up in ponds and lakes serves as a food supply for algae and weeds leads to eutrophication. This is abundant in the water bodies of Kerala and there is a lot of scope for potential saving measures for these treasures we need to protect. Biological treatments including Biofiltration, Aeration and Nutrient removal are applied in such systems to reduce the pollution and for in-situ treatment. Microbial cultures prepared from natural strains specially prepared for these systems are available which will eventually help in restoring the natural ecological balance of the water body.
