01.
Q: What can be done to the well if sand continues to enter a well after the well development has been carried out?
A: The well driller can try to run the pump at its maximum capacity in short periods of time over a couple of days
01.
Q: What can be done to the well if sand continues to enter a well after the well development has been carried out?
A: The well driller can replace the casing with a new one with smaller slots
01.
Q: What can be done to the well if sand continues to enter a well after the well development has been carried out?
A: An additional filter can be installed inside the casing
02.

04.
Q: In which areas is there a bigger risk of pumping corrosive groundwater?
A: In forests with old trees
04.
Q: In which areas is there a bigger risk of pumping corrosive groundwater?
A: In coastal areas
04.
Q: In which areas is there a bigger risk of pumping corrosive groundwater?
A: In elevations above 1000 m
05.
Q: By-pass control is an efficient way of performance regulating a pump but what is the downside of the process?
A: The by-passed water is wasted and cannot be used again
05.
Q: By-pass control is an efficient way of performance regulating a pump but what is the downside of the process?
A: The motor temperature rises and increases the risk of motor burn-out
05.
Q: By-pass control is an efficient way of performance regulating a pump but what is the downside of the process?
A: Energy is wasted as the pump continues to run at full speed
06.
Q: What is the most effective way to stay updated on your pump’s condition?
A: Manual inspection
06.
Q: What is the most effective way to stay updated on your pump’s condition?
A: Remote online monitoring
06.
Q: What is the most effective way to stay updated on your pump’s condition?
A: Regular maintenance
07.
Q: How is it possible to protect the motor against bad power supply?
A: By means of an electronic motor protection that senses all possible deviations
07.
Q: How is it possible to protect the motor against bad power supply?
A: By means of a UC filter
07.
Q: How is it possible to protect the motor against bad power supply?
A: By using a special water resistant cabling
08.
Q: Why is it a good idea to make a well where the groundwater level is as high as possible?
A: The shorter the distance is to the water the less expensive it is to make the borehole and subsequently to pump the water to the surface
08.
Q: Why is it a good idea to make a well where the groundwater level is as high as possible?
A: The shorter the distance is from the surface to the ground water, the better the water quality is
08.
Q: Why is it a good idea to make a well where the groundwater level is as high as possible?
A: A higher level means lower water temperatures and better motor cooling
