Test results
01.
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
01.
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
01.
Q: Why is the life cycle cost of the pressurised wastewater system low?
A: The lifting station and the pipe system is maintenance-free
02.
Q: What are the disadvantages of the traditional gravitation system?
A: Many gravitation pipes with a small diameter have to be installed outside the building and the inspection wells are expensive
02.
Q: What are the disadvantages of the traditional gravitation system?
A: Inspection wells are difficult to maintain and the initial cost of the pumping pit is high
02.
Q: What are the disadvantages of the traditional gravitation system?
A: Many gravitation pipes have to be installed outside the building and a great deal of excavation work is needed.
03.
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
03.
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
03.
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
