Septic design for Minoa, NY, from soil test to county approval.
The Village of Minoa has its own wastewater treatment facility at 100 Kalin Drive serving about 3,345 residents. Rural parts of the surrounding Town of Manlius lack public sewer according to the 2023 town plan.
It is a hard one. The USDA describes Minoa soils as somewhat poorly drained deltaic sediments on lake plains. With high spring water, raised beds and mounds are common, and about 96 percent of rated land around the village is very limited for conventional fields.
Not below the 10 year flood level under Appendix 75-A, and county guidelines require the system above the 100 year flood level with elevations shown on the plan.

Septic engineer in Minoa, NY: what it is and who needs one
Minoa is the village that gave its name to a soil series, and that soil explains most septic jobs around it. The Minoa series is a somewhat poorly drained deltaic soil on old lake plains, wet in spring. Inside the village there is sewer. Outside it, in the Town of Manlius around Kirkville and Manlius Center, a septic engineer tests the soil, designs to Appendix 75-A, and gets approval from the Onondaga County Health Department.
Backwell coordinates testing, design, the submittal and the install. Designs are prepared and stamped by a New York licensed Professional Engineer (PE).
Minoa's own treatment plant
Minoa is not on WEP's list of villages in the county Consolidated Sanitary District, because it runs its own system. The Minoa Wastewater Treatment Facility at 100 Kalin Drive serves about 3,345 residents through 28.5 miles of sewer and one main pump station. It also takes flow from ESM High School, Pine Grove Middle School, Woodland Elementary and the ESM bus garage outside the village. The village notes a large section of the collection system is built below the groundwater level, which tells you how high the water sits here. The 1997 upgrade added sequencing batch reactors and three constructed wetlands.
The surrounding Town of Manlius is in the county district, but its 2023 plan says the low density rural areas have no public sewer.
Soils in Minoa and the system they point to
Around Minoa the land is low. Niagara silt covers the largest share, followed by Camillus soils over shale on the rises, the Minoa series itself, and Teel and Wayland floodplain soils along the creeks.
| Soil series | Share of land | What it is (USDA) | What it usually means for the design |
|---|---|---|---|
| Niagara | 17% | very deep, somewhat poorly drained silty lake sediments | High seasonal water and slow perc. Raised beds and mounds are common here. |
| Camillus | 9% | moderately deep, well drained soil over weathered calcareous shale | Shale shows up inside the 4 feet a conventional field needs, which points to shallow trench or raised designs. |
| Minoa | 7% | very deep, somewhat poorly drained deltaic sediments | The series is named for Minoa. Fine sand with high spring water, a classic raised bed or mound soil. |
| Teel | 6% | very deep, moderately well drained silty floodplain soil | Floodplain soil. The field has to sit above the 100 year flood level per county guidelines. |
| Wayland | 5% | very deep, poorly to very poorly drained floodplain alluvium | Wet and flood prone. Rarely a field location. |
| Ontario | 5% | deep or very deep, well drained loamy till on drumlins and till plains | Usually workable for conventional or shallow trenches. Drumlin slopes can push past the 15 percent limit. |
USDA septic absorption field ratings, a box reaching about 2 miles out from the Village of Minoa line: very limited 96 percent, somewhat limited 4 percent of rated land. Leading limits: slow water movement, shallow seasonal water, flooding.
About 96 percent of the rated land around the village is very limited for a conventional field. Slow water movement leads, then seasonal water, flooding and ponding. On Minoa and Niagara soils, a raised bed or mound is the usual answer, because 75-A needs 2 feet between the trench bottom and the high water, and these soils often show water at 1 to 2 feet in spring. Wayland floodplain soil is rarely a field location at all. On the Camillus rises, rock rather than water is the limit.
Flooding and wetlands around Minoa
Flooding shows up among the top soil limits here, which is unusual. The county guidelines require every part of the system above the 100 year flood level, documented on the plan, and Appendix 75-A rules out the area below the 10 year flood level entirely. Fields stay 100 feet from streams and wetlands. Green Lakes State Park lies southeast of the village.
How a septic design in Minoa works
- Send the address. Use the form. Estimate in 1 hour.
- Confirm sewer or septic. If a public sewer can serve the lot, you do not need a septic design.
- Perc holes and a deep test pit. At least two staked perc holes in the design area (30 inches deep for a conventional system) and a test pit logged to 6 feet for mottling, water and rock.
- Stamped design. A scaled plan with the tax map number, nearby wells, elevations and system details. Designs are prepared and stamped by a New York licensed Professional Engineer (PE).
- County submittal. Plan and fee go to the Bureau of Public Health Engineering, 421 Montgomery Street, Syracuse: 3 plan copies outside the lake watersheds. Once approved, a copy goes to the town.
- Building permit. Inside the village, Minoa Codes Enforcement at 240 N Main Street. In the town, Manlius Planning and Development at 301 Brooklea Drive.
- Install and inspection. County inspection on 24 hours notice. Inside plumbing is done by a plumber licensed through Onondaga County Plumbing Control, and fill systems get the engineer's fill certification first.
What it costs
The county fee schedule sets the health department side for a lot under 1,000 gallons per day: $310 full application, $186 redesigned project, $62 amended project or revised plan review, $93 site investigation, $62 repair inspection. The fee is paid with the plans and covers the county's review and construction inspection. Testing, design and install are priced in writing.
What the health department checks
The county reviews the plan against New York's Appendix 75-A and its own design guidelines. Around Minoa the checks that matter most are the 2 foot separation to seasonal high water, the flood elevation, and the 100 foot setback from creeks and wetlands.
- Flow and tank. 110 gallons per day per bedroom for new construction. Tank size follows the bedroom count.
- Usable soil. Conventional: 4 feet over rock, clay or high water, with water 2 feet below the trench bottom. Shallow trench: 2 to 4 feet. Raised bed: 1 to 2 feet, water 1 foot down. Mound: water 1 foot down, rock 2 feet down, native perc faster than 120 minutes per inch, slope under 12 percent.
- Separations. Field, raised bed or mound: 100 feet to wells (200 if upgrade in the drainage path), 100 feet to water and wetlands, 20 to the house, 10 to the lot line, measured from the toe of any fill. Tank: 50 feet to wells and water.
- Site limits. No field over 15 percent slope or below the 10 year flood level, system above the 100 year flood level, no soil faster than 1 minute per inch unless modified, and 50 percent expansion area where possible.
Common Minoa problems and how the design handles them
The Minoa soil itself
The problem: Somewhat poorly drained deltaic sediment with high spring water.
How the design handles it: The pit is logged for mottling. With water 1 to 2 feet down, a mound (if native soil percs faster than 120 minutes per inch) or a raised bed.
Lot near a creek floodplain
The problem: Teel and Wayland soils are floodplain soils, and the system must be above the 100 year flood level.
How the design handles it: The PE shows the flood elevation on the plan and puts the field on the high ground, with a pump if the house sits lower.
Replacing a failed field in wet ground
The problem: A field built in the wrong soil years ago will keep failing if rebuilt in the same spot.
How the design handles it: Replacement starts with new tests and a design that meets the water separation, usually in fill.
Timeline
Test in spring if possible, since that is when the Minoa soils show their water. Mounds get formal county approval once there is a schedule to build in dry conditions. Raised beds wait on the engineer's fill certification.
