IrrigationPregunta 4 de 100
Under California's Model Water Efficient Landscape Ordinance (MWELO), overhead spray irrigation is generally prohibited in landscape areas narrower than what width?
a.Less than 24 inches
b.Less than 18 inches
c.Less than 12 inches
d.Less than 24 inches (narrow strips) unless low-volume methods are used
Explicación
MWELO restricts overhead spray in narrow strips, commonly areas less than 24 inches wide, because overspray onto pavement wastes water and causes runoff. Narrow strips should use drip, subsurface, or other low-volume irrigation. This reduces water waste and meets the ordinance's efficiency goals.
