Public Record Notice & Schematic Blueprint Disclaimer:
This technical drawing is an illustrative layout model depicting typical Maui County (Hawaii) setback geometry (house, 50-ft well buffer, 5-ft property boundary clearances) for standard residential onsite septic systems. It is NOT the surveyed blueprint of this specific property. Exact physical triangulation distances from house corners are preserved in the original hand-drafted inspection file (Permit #HI-IWS-257009002) on file with Hawaii State Department of Health - Wastewater Branch (Maui District Office).

Sanitary Setback Standard: Under Hawaii environmental health code, all septic absorption drainfields must observe a minimum horizontal separation of 50 feet from any private drinking water well heads and 5 feet from property boundaries.
Quick Field Tank Locator
Maui County • HI Field Standard
Use this quick 4-step checklist to pinpoint your underground tank lids in the yard before routine pumping or inspection.
1
Trace Foundation Sewer Exit Line
Locate the 3-inch or 4-inch main DWV waste pipe exiting the basement, crawlspace, or bathroom exterior foundation.
Under gravity standards, the tank inlet lies along a straight line projected perpendicular from this foundation exit point.
2
Spot 4-Inch Cleanout & Setback Vector
Look for a threaded 4" PVC cleanout cap 3 to 5 feet outside the house foundation wall.
Setback (Hawaii Onsite Wastewater Regulations): Requires minimum 5-ft foundation clearance. Installers typically set the tank 10 to 20 feet away along this cleanout axis.
3
Check Turf Outline & Estimated Footprint
For this 1,000-gallon tank, expect an underground footprint of approx. 5 × 8 ft at 12–36 inches depth.
Summer / Dry Spell: Grass directly over shallow tank lids dries and yellows faster than surrounding lawn.
Winter / Frost: Bacterial warmth (50°–60°F) inside the tank melts snow and morning frost premature to the yard.
4
Non-Destructive Soil Probing Feedback
Using a blunt-tip steel T-handle probe, insert every 12 to 18 inches starting 10 ft out from your cleanout.
Lid Contact: Unyielding solid "thud" across a continuous approx. 5 × 8 ft horizontal span.
Rock vs. Root: Rock produces sharp scratch deflection; tree roots yield with a spring-back bounce.
Compliant with Hawaii Onsite Wastewater Regulations (5-ft foundation setback)Never drive vehicles or heavy equipment over the tank or drainfield corridor

Under State Underground Utility Protection Statutes (National 811): Always call 811 two full business days before inserting steel probes or excavating. Private septic lines are not marked by 811, but public utility clearance is legally mandatory.

Service Status
Select Year to Check Status
EPA Regulatory Requirement (The 1/3 Rule): Regardless of calendar years, a septic tank must be pumped whenever the floating scum layer comes within 6 inches of the outlet baffle or accumulated bottom sludge exceeds 30% to 33% of the liquid depth. Standard gravity systems require professional inspection every 1 to 3 years.
Under Hawaii Onsite Wastewater Regulations, routine septic tank cleanouts are performed by privately contracted, state-licensed septic tank contractors. Routine pump-out receipts are maintained by the property owner and the service company. For a 1,000-gallon tank, state environmental health guidelines recommend the following pumping intervals:
Household OccupancyRecommended Interval
1 to 2 occupantsLight household water usage
Every 4 – 5 years
3 to 4 occupantsStandard residential usage
Every 3 – 4 years
5+ occupantsHeavy usage or garbage disposal equipped
Every 2 – 3 years
💡 Inspection Tip: Never allow heavy equipment or vehicles to drive over your 1,000-gallon tank or drainfield absorption area.

[ ]
1. Maintenance Log & Pumping Receipts: Seller to provide verified receipts from licensed septic service company covering past 3 to 5 years.
[ ]
2. Professional Pre-Closing Inspection: Buyer advised to commission independent inspection (hydraulic dye test, tank baffle inspection, and drainfield camera scope).
[ ]
3. Bedroom Capacity Verification: Verify residence does not contain unpermitted bedrooms exceeding the approved design-bedroom limit (excess occupants cause premature drainfield saturation).
[ ]
4. Surface Clearances & Risers: Verify tank access lids and effluent filter risers are secured to grade, undamaged, and clear of soil obstruction.
