Up front capital invested can range from as low as $500 for a small, shallow pond aeration system to as much as $8,000 or more for a larger system or a solar aerator.Operating cost is dependent on the number of amps needed to power an electric motor multiplied by the electricity cost in your area.ome electric aerators might run for 2-3 years without any major issues and others might run 5-7 years or longer. The table below is based on a set of assumptions that is fairly representative of actual costs for a 1 to 2 acre pond or small lake.
Surface Hub costs less than half that, and is in essence a collaborative center in a box. Costs for a conference room that would accommodate the lower-end unit are about $6,500 to $27,000, again not including furniture, installation, service, and ongoing management costs, so a similar savings can be had there as well.
I believe that these figures are very conservative estimates. I've read that surface parking can cost as much as $10,000 per space and subterranean parking can cost as much as $25,000 to $35,000 per space.Of course these figures will change dramatically depending on what part of the country the parking is being built, the scarcity of land, etc. etc. believe that these figures are very conservative estimates.
