Irrigation can be well distributed over several nights or mornings. In summer, 2-3 rounds per week are usually sensible. Drip irrigation can also run during the day. There are enormous differences in sprinklers regarding range, angle, precipitation per m2, water consumption, etc. This also determines how long watering must last. Together with the piping and water supply, this results in the number of sprinklers per zone. However, this varies by zone. A sprinkler with 360° uses 4 times as much water as a 90° sprinkler of the same design. Therefore, statements or recommendations about how many sprinklers one has or can have per zone do not make sense. depends on the water connection in terms of flow rate and not pressure. Many underestimate water demand. Manual irrigation is not comparable. Lawn needs about 20 liters per m2 per week in summer. For Steffen, this would already be 48m2 of water per month (without natural precipitation). This shows that a well is very useful. Despite electricity costs for the pump, it pays off quickly. Also, a cistern. This way, rainwater can be collected. The size must be adapted to the roof area and natural precipitation. A combination of well and cistern is the best (and most complex) solution. Supply from the water pipe is the worst way due to flow, costs, and ethics.
