The Norwesco 300 Gallon Septic Pump Tank (MPN N-41319) is a polyethylene septic tank engineered to replace legacy steel and concrete septic tanks — corrosion-immune, lightweight enough for one-truck set, and certified for code-conforming residential septic-system installation.
Design
- Lightweight enough for one-truck set: typical 1000-gal HDPE septic tank weighs under 300 lb empty vs. 7,000+ lb for equivalent concrete
- Manufactured to IAPMO IGC 247 (where labeled certified) for residential single-family on-site sewage treatment
- Polyethylene shell is corrosion-immune to sewage gases (H2S, CH4, NH3) that pit and crack steel and concrete tanks
- Internal baffle (one-compartment) or compartment-divider wall (two-compartment) integrally molded — no field assembly
- Manway risers and lid accessories sized to the OEM connection — specify when ordering
Installation
Install per the local on-site sewage treatment code (typically a state-level adoption of IAPMO Uniform Plumbing Code Chapter 7 or the International Private Sewage Disposal Code). Bury depth, backfill material, inlet/outlet invert elevations, leach-field sizing, and required permits are jurisdiction-specific — verify with the local health department before excavation. Lay the tank on a level sand or pea-gravel bedding course; backfill with the same material to prevent point-loading on the rotomolded shell.
Common applications
- Remote-research-station and field-camp on-site sewage treatment
- Single-family residential septic primary treatment tank
- Cabin, lake-house, and weekend-property on-site sewage treatment
- RV park, campground, and recreational-facility shared-system septic
- Light-commercial septic for restaurants, gas stations, and small offices in rural jurisdictions
- Replacement for failed steel or concrete legacy septic tanks
Compatibility & compliance
Where carrying the IAPMO IGC 247 certification mark, the tank is approved for residential single-family on-site sewage treatment systems under jurisdictions adopting the Uniform Plumbing Code or International Private Sewage Disposal Code. State-level approvals (Florida, Massachusetts, California, others) are jurisdiction-specific — verify the model's approval status with the local health department before purchase.
