entered rate on base pipe length. Default preview: $812.50.
Methodology
Transparent calculation
BuildMeter converts every input to a consistent internal unit, applies the selected allowance, and rounds products up to whole purchasable units.
Pipe order = entered length × allowance. Material cost adds mainline, lateral pipe, outlets, one valve allowance per zone and controller accessories. Labor uses the base pipe length.
FAQ
Garden Irrigation Cost Calculator questions
Why price mainline and lateral pipe separately?+
Mainline and lateral sections often use different diameters, pressure ratings and material costs.
Are trenches and restoration included?+
Only when the entered installation rate is sufficient for excavation, backfill and landscape repair.
Does this determine the number of zones?+
No. Zone count depends on available flow, pressure, outlet type and hydraulic design.
