Mains powered aeration systems are considerably more affordable than solar powered setups. Sometimes they are half the cost. It’s also important to be aware sub-surface aerators can be installed up to 200m from the water’s edge. In other words, if your dam is 200m from a power outlet, mains power is an option for you. This is why we need all the info, so we can provide you with the most cost-effective option. If cost is not a concern and solar is your preference, please make a note of this in your enquiry.
