Wastewater collection in sewer systems

The hydraulic dimensioning of a sewer system is indispensable for an efficient urban and private drainage. For that reason, the optimization measures of sewer systems concerning impoundage and flooding is needed. Aiming for a minimization of combined sewer overflow into the receiving waters and a safe regulation after impoundage in the sewer system technical measures have to be taken. During construction planning a wastewater disposal concept is developed (and implemented) containing specific technical measures.

• Remediation plans for urban sewer systems
• Hydraulic and substance-related verifications (pollution-load-simulations)
• Real-time control concepts of urban drainage systems
• Risk assessment and evaluation of possible impact of heavy rain events
• Flood protection concepts for sewer systems
• Concepts for the reduction of extraneous water

• Development of  master plans for urban drainage systems
• Create sustainable concepts for sewage, extraneous water and storm water disposal
• Hydrodynamic simulation of sewer systems (HYSTEM-EXTRAN)
• Hydrological and hydrodynamic pollution load calculations (KOSIM, HYSTEM-EXTRAN)
• Integrated 1D/2D simulation of sewer systems and flooding (HYSTEM-EXTRAN 2D)
• Dimensioning and proof of flood pumping stations
• Optimization of the waste water inflow into the waste water treatment plant (WWTP)
• Monitoring concepts for rainfall and flow/water level measurements
• Set-up and calibrate sewer system models
