A dumping well comprising:
- a tank for containing a liquid;
- an upper liquid level detector for detecting an upper liquid level in the tank;
- a lower liquid level detector for detecting a lower liquid level in the tank;
- a dump valve for dumping liquid from the tank;
- and
- a control system for opening the dump valve in response to the upper liquid level detector detecting an upper liquid level in the tank, and for closing the dump valve in response to the lower liquid level detector detecting a lower liquid level in the tank;
- in which the dump valve is operated by a pressurized fluid, and the control system is configured to open the dump valve by opening a control valve connecting the dump valve to a supply of pressurized fluid and to close the dump valve by closing the control valve.
