Achieved badges:
Q: How can you tell if you need to establish a drainage system as part of your building project?
A: If the building next door does not have a drainage system, your building does not need one either.
Q: How can you tell if you need to establish a drainage system as part of your building project?
A: When the projected area of a building exceeds 2.000 m2 a drainage system is required.
Q: How can you tell if you need to establish a drainage system as part of your building project?
A: By conducting a thorough pre-investigation of the conditions of the soil, the groundwater conditions, and the drainage situation on neighbouring lots.
Q: What are the approaches that can reduce hydrostatic pressure on your building?
A: Constructing a robust foundation, anchoring the building to the underground, or installing a drainage system – or all three in some cases
Q: What are the approaches that can reduce hydrostatic pressure on your building?
A: There is no need to reduce the hydrostatic pressure as it adapts automatically to the weight of the building.
Q: What are the approaches that can reduce hydrostatic pressure on your building?
A: Using the help of the local water supply company to once a year pump away the rising ground water around the building.
Q: When is it ideal to use a lifting station as a pressurised system for wastewater removal in commercial buildings?
A: When sanitary appliances are installed in the basement of an existing building, when space outside the building is limited or when excavation conditions are difficult.
Q: When is it ideal to use a lifting station as a pressurised system for wastewater removal in commercial buildings?
A: When there is a need to remove black and grey wastewater, drainage water and surface water.
Q: When is it ideal to use a lifting station as a pressurised system for wastewater removal in commercial buildings?
A: When storage of wastewater volumes is required over a longer period of time.
Q: Would you recommend drainage around a building if there was soil of permeability and the groundwater level was above drainage level?
A: No
Q: Would you recommend drainage around a building if there was soil of permeability and the groundwater level was above drainage level?
A: Yes
Q: Would you recommend drainage around a building if there was soil of permeability and the groundwater level was above drainage level?
A: Could be necessary if the groundwater level is expected to rise
Q: Why is a lifting station an optimal solution for basement refurbishments?
A: A lifting station is flexible, easy to service, cost effective, provides protection against flooding and is odour free. It can also be connected to the existing drainage pipe easily.
Q: Why is a lifting station an optimal solution for basement refurbishments?
A: A lifting station is a versatile solution that can handle both black and grey wastewater, drainage water and surface water.
Q: Why is a lifting station an optimal solution for basement refurbishments?
A: The built-in frequency converter makes the lifting station very flexible for fluctuations in the discharge profile of the sanitary appliances.
Q: What does a Grundfos MULTILIFT protect against?
A: Flooding of cooling towers
Q: What does a Grundfos MULTILIFT protect against?
A: Too high concentration of faecal matters in the wastewater
Q: What does a Grundfos MULTILIFT protect against?
A: Backflow and basement flooding
