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.
The Surface Hub is available in two sizes. The first measures 55 inches and is designed for huddle spaces, smaller conference rooms, and offices. Its cost is set at $6,999 (USD). For larger meeting spaces, there's an 84-inch model that costs $19,999. These prices are not unreasonable when compared to what Polycom and other companies charge for their conference room solutions.
Once you begin construction of the building, if you're going to build single story units, you can expect to pay $25 to $40 per square foot you build. If you want a multi-story building, costs will be around $42 to $70 per square foot. Mako Steel estimates the most high-end self storage facilities have somewhere between 60,000 and 80,000 rentable square feet, and costs $45 to $65 on construction per square foot. The cost of construction will also depend on the unit's amenities, such as if the unit is climate controlled.
