Leaking dams are a standard problem and may be very expensive to fix. Water in Australia is such a useful commodity, retaining the water is most important. In lots of areas it is only occasionally it rains heavily enough for runoff into dams to occur so fixing the leak is crucial.
Quite a few solutions to the problem are available.
The most effective answer is to install a dam liner which is a guarantee to repair the problem. Nevertheless this method is dear and the liner can only be installed when the dam is empty. Therefore it means waiting until the dam is empty or having to pump out the stored water and hope for heavy rain. Another resolution is by adding chemical substances which combine with the soil to stop the leaks. Once more this may be expensive and is not guaranteed to work if there's insufficient clay or tree rotes in the dam wall.
Putting in a solar pump is a assured answer and once installed costs nothing to run. A simple answer is to make a small pond under the dam wall and set up a photo voltaic pump to pipe the water again into the dam. As solar pumps only operate in daylight hours the pond needs to be about thrice the every day leaking volume. For example a dam leaking at 2.5L/M or 3600 litres per day had a 12000 litre pond constructed and a photo voltaic diaphragm pump with a capacity of 17 L/M installed and the issue was solved. Even on overcast days the pond didn't overflow and a float switch was installed to show off the pump at the low water stage.
There are two forms of photo voltaic pumps suitable for this software.
One is a submersible connected to the solar panels by way of an inverter which converts the DC present from the panels to 3 phase AC power to the pump. To forestall the photo voltaic water pump from running dry, high water and low water probes are installed which are linked to the inverter.
The other appropriate photo voltaic pump is a less expensive mounted displacement diaphragm unit which is connected to the photo voltaic panel through a battery. To prevent dry operating an inexpensive float swap will be installed.
To extend every day move charges by 30% a solar tracker will be installed.
Most dam leaking issues could be solved with solar water pumps but when the leak gets to unacceptable flows other options could also be needed but the solar pump can still be used for different purposes.
