Q: Which treatment is necessary for storm water?
A: It has to go through an oil/petrol separator
Q: Which treatment is necessary for storm water?
A: It has to go through a sand pressure
Q: Which treatment is necessary for storm water?
A: None – it is pumped directly to the recipient
Q: Who has the financial responsibility in the case of flooding in most countries?
A: The building owner and the building designers
Q: Who has the financial responsibility in the case of flooding in most countries?
A: The government and the wastewater authorities
Q: Who has the financial responsibility in the case of flooding in most countries?
A: The building designers and the contractors
Q: Under which circumstances should you consider a pressurised wastewater system rather than a gravitation system
A: When there is a long distance between the building and the sewer main, when the sewer main is up-hill or when there are obstacles between the building and the sewer main.
Q: Under which circumstances should you consider a pressurised wastewater system rather than a gravitation system
A: When there is a long distance between the building and the sewer main or when the sewer main is located far below the building.
Q: Under which circumstances should you consider a pressurised wastewater system rather than a gravitation system
A: When there is a short distance between the building and the sewer main or there are obstacles between the building and sewer main.
Q: What are the four most common types of wastewater from commercial buildings?
A: Wastewater, storm water, drainage water and wastewater from parking areas
Q: What are the four most common types of wastewater from commercial buildings?
A: Rainwater, wastewater, storm water and drainage water
Q: What are the four most common types of wastewater from commercial buildings?
A: Wastewater, storm water, air-conditioning wastewater and wastewater from parking areas
Q: Why is the life cycle cost of the pressurised wastewater system low?
A: There are only a few gravitation pipes outside the building and the excavation cost is low
Q: Why is the life cycle cost of the pressurised wastewater system low?
A: The initial cost of the lifting station is lower compared with a pit and there are no gravitation pipes outside the building
Q: Why is the life cycle cost of the pressurised wastewater system low?
A: The lifting station and the pipe system is maintenance-free
Q: Of the three anti-flooding systems, why is the lifting station the superior system?
A: It is located outside the building which means bad odour is never a problem
Q: Of the three anti-flooding systems, why is the lifting station the superior system?
A: The storage volume is high and it is easy to assemble and install
Q: Of the three anti-flooding systems, why is the lifting station the superior system?
A: It is pre-assembled and its location inside the building makes it easily accessible for service. Furthermore, it offers maximum backflow and flooding protection
