Workshop

Integrated wastewater management - from the household to the watershed level

Integrated wastewater management from the individual household level to the watershed level is an indispensable segment for the long-term and sustainable maintenance of the natural biological balance and the protection of human health through the maintenance of a minimum good ecological and chemical status of surface water and groundwater bodies respectively. The goal of the workshop is to provide participants with new knowledge that is directly applicable to professional practice through a carefully designed, comprehensive, and interdisciplinary approach. The workshop provides participants with professional training in the field of technical sciences, in the field of civil engineering, in the branch of hydrotechnical engineering, then in the field of chemical engineering, in the branch of environmental protection in chemical engineering and in the field of mining, petroleum and geological engineering, in the branch of geological engineering and in the field of natural sciences, in the field of interdisciplinary natural sciences, in the branch environmental sciences.

Duration of the workshop: 8 school hours
Participants: 20-40

Learning outcomes:

• Determination of relevant hydraulic load and waste load (COD, BOD5, TSS, TN, TP) in raw and treated wastewater (from household level to watershed level)
• Determination of relevant flow in surface water bodies as recipients of raw and treated wastewater
• Determination of boundaries of the watershed in which integrated wastewater management will be implemented
• Understanding the “effluent criteria” and “recipient criteria” when discharging treated wastewater into surface water bodies
• Adoption of a combined approach methodology for a single discharge of treated wastewater into surface water body: calculation of waste concentrations at the mixing point, analysis of organic matter transfer and oxygen balance in surface water bodies
• Adoption of a combined approach methodology for a larger number of discharges of treated wastewater discharges into surface water bodies at the watershed level
• Determination of the maximum daily load in receiving surface water bodies at the watershed level
• Hydrogeological characterization of receiving groundwater bodies as recipients of raw and treated wastewater
• Application of methodology to determine natural and specific vulnerability using the examples of receiving groundwater bodies
• Understand the importance of conceptual models to qualitatively or quantitatively determine the degree of interaction between groundwater and terrestrial and aquatic ecosystems and the actual or potential use or function of groundwater
• Application of methodology to determine the ambient background concentrations of characteristic substances that may occur in groundwater due to natural or anthropogenic processes
• Determination of Reference Quality Standards or Criteria Values of substances that may contribute to the risk of not achieving environmental goals for receiving groundwater bodies
• Application of a tiered approach to determine threshold values for substances that may contribute to the risk of not achieving environmental goals for receiving groundwater bodies
• Application of the methodology for risk assessment of non-attainment of environmental objectives for groundwater using the examples of receiving groundwater bodies
• Determination of the maximum daily load in receiving groundwater bodies at the watershed level
• Adoption of a strategy to determine the required efficiency of wastewater treatment plants in the watershed, taking into account the carrying capacity of receiving surface water and groundwater bodies
