Excavation contractors in Upcountry Maui

Upcountry is where Maui excavation gets technical. Steep slopes on Haleakalā, rocky ground, catchment water systems and thousands of cesspools make it the busiest area for septic and site work on the island.

The cesspool question

About 7,400 of Maui's 12,000-plus cesspools are Upcountry, and the area is a priority for conversion because of groundwater nitrate contamination. Under Act 125, every cesspool must be converted by 2050. Read the cesspool conversion guide.

Slopes, rock and the 2023 Kula fire

Many Kula and Makawao lots need cut-and-fill pads, retaining walls and careful drainage, and rock can show up anywhere. The 2023 fire destroyed homes in Kula, and rebuilds there have run into wastewater upgrade costs. See rebuilding after the fires and digging in lava rock. Land clearing for fire safety still needs a grubbing permit. See the permit guide.
