The studies covered the branches: sugar industry, fruit-and-vegetable processing and potato processing plants. The analyses of water consumption and quantities of wastewater formed in 24 production plants were performed in the paper. A comparison of water and wastewater management in three branches showed that the highest water consumption is in fruit-and-vegetable processing. The data collected in the paper indicates the drop of water consumption in potato as well as fruit-and-vegetable industry. The values obtained for sugar industry indicate that it is the least diversified branch.
