Under level 1 water restrictions under section 44(3) of the Water Services By-law, declared each summer, watering is not allowed between 06:00 and 18:00, so water before 06:00 or after 18:00. The best time for the plants is the early morning, 04:00–06:00, when little is lost to evaporation and the leaves dry as the sun comes up.
The notice speaks of watering gardens generally and does not exempt borehole water. Ask Johannesburg Water before relying on a borehole during restricted hours.
That depends on the month, the planting and the sprinklers, not the city alone. The watering schedule on this site works it out from the climate recorded at your address and turns it into minutes for each month, inside Johannesburg's hours.
