What’s the difference between commercial irrigation and residential irrigation?

A good question to ask yourself when installing a commercial irrigation system or a residential irrigation system is what separates the two? Understanding the differences can actually save you a ton of money. A residential irrigation zone is considered a single family home zoning while commercial is/are apartments, businesses, schools and farms.

The water source is the key for saving money on installation. In example, the pressure. In a commercial area, you may be relying on city pressure in which you could have to install heavy pumps and think pipes to handle a specific area. This could cost a lot of money, however, you could use that to your advantage and install a residential irrigation in a commercial if your installer understands the zoning and pressure requirements.

Zone sizes matter as well. Each zone represents the amount of water that needs to be used and what PSI (pressure) needs to be propagated. All depends on the available flow and what pump you are using including the rotors and sprinkler heads. The irrigation system will fail if these zones and pipe routing are not setup properly. By using the Gallon Per Minute (GPM) rate, contractors will divide the dividing the daily flow by the available water time which is about 8 hours.

Larger sources of water mean more control and cheaper installation of irrigations. In example, well water with a good pump can determine what sizes of pipes to use and different sizes of the zones. The less zones, the less rotors. The more water pressure, the less sprinkler heads etc. The larger the water source, the more it gives you freedom to use pump sizes. If you are running on city water, you cannot go any higher than what the PSI is coming in at.

Rotors help the spray of water go farther. The more PSI (larger pumps), the bigger zones you can use which will save you more money. Rotors are typically used for commercial irrigations unless the residential owner has their own water source (lake, river, pond or well). What timers and heads you use for your sprinklers and/or rotors will determine the costs as well. Residential uses heads and commercial uses rotors.
