A field that stays soggy or backs up again right after pumping is usually done; biomat clogging does not heal. A sound tank with a failed field means field-only replacement. A cracked, rusted-out steel, or collapsing tank means tank replacement. We tell you which one you actually need after the site visit, in writing.

Yes, if the tank passes inspection. We perc test the replacement area, design to NYSDOH 75-A separation and sizing, and tie the new field into your existing tank. If the original field area is exhausted, the new field goes in a reserve area.

From signed contract to mobilization is typically 2-5 weeks, mostly county permit and design time. Active dig time on the property runs about 2-5 days for a conventional replacement, longer for engineered mound systems.

Yes. Design, county health department permit, inspections, and the final as-built all go through us. You sign one contract and get one written fixed price.

Replacement, Not Patchwork

Most failed systems in Tully went in decades ago and were sized for smaller households. We do not nurse a dead leach field along with pump-outs. We perc test, design to current NYSDOH 75-A, and put in a system that passes inspection and holds up.

Soils, Water Table & Septic Replacement Conditions in Tully, NY (Onondaga County)

Tully occupies the Appalachian Plateau in southern Onondaga County, on the headwaters divide between the Atlantic and Great Lakes drainages. Soils across the village and surrounding commercial parcels are dominated by Mardin and Langford channery silt loams on the rolling uplands, with Lordstown channery silt loam on the highest ground and Palmyra gravelly loam on the outwash in the Tully valley itself.

The Tully Valley is one of the most distinctive hydrogeologic settings in Central New York, with Onondaga Creek draining north toward Syracuse, the Tioughnioga headwaters draining south, and the historic Tully Valley mudboil and landslide activity adding karst and slope-stability considerations to any earthwork on the valley walls. Commercial site work in Tully regularly involves shallow sandstone and siltstone bedrock on the plateau parcels, fragipan-restricted drainage on the uplands, and stormwater design that accounts for the Onondaga Creek watershed's contribution to Onondaga Lake. Frost depth is substantial. Projects in the valley floor routinely require coordination with NYSDEC on Onondaga Creek stream-protection permitting, and subsurface investigation is standard before slab or foundation work.
