110 Gallon Full Drain Cone Bottom Inductor Tank: Complete Buyer's Guide
110-gallon white rainwater harvesting tank built for rainwater harvesting and collection. Manufactured by Norwesco from virgin linear polyethylene (HDPE) rated to handle liquids up to 12.5 pounds per gallon. FDA approved for contact with potable water, ensuring safe storage for drinking water and food-grade liquids.
Product Overview
The 110 Gallon Full Drain Cone Bottom Inductor Tank is designed for environmentally-conscious homeowners and commercial property managers implementing rainwater collection systems. The 110-gallon capacity hits the sweet spot for rainwater harvesting and collection — large enough to be genuinely useful, compact enough to install without heavy equipment or specialized foundations.
Constructed from virgin linear polyethylene (HDPE) using a single-piece rotational molding process that eliminates seams, weld lines, and potential leak points. Rated to 1.5 specific gravity, this tank handles liquids up to 12.5 pounds per gallon — covering the full range of agricultural chemicals, liquid fertilizers, and most industrial solutions. The wall thickness is engineered specifically for this density range. Translucent white walls allow visual level monitoring without opening the tank and reflect sunlight to keep contents cooler. Maximum operating temperature is 120 F / 48 C, with UV stabilizers compounded directly into the resin for outdoor service life.
This tank measures 56 inches tall with a 30-inch diameter, requiring 4.9 square feet of level ground. Empty weight is 44 pounds. At full capacity with a 1.5 SG liquid, expect approximately 1,420 pounds on the foundation. Set on a flat, level pad of compacted gravel or a concrete slab at least 4 inches thick. Place on a firm, level surface free of rocks or sharp objects that could damage the tank bottom. Ensure adequate ventilation if stored chemicals produce vapors.
Comes equipped with a 2" NPT outlet fitting installed at the factory. No inlet fitting is included — drill and install a bulkhead fitting at your preferred height for your specific plumbing layout. The 16" lid opening provides ample access for interior inspection, cleaning, and installation of float switches, level sensors, or submersible pumps. We recommend schedule 80 PVC or polypropylene fittings on the 2" NPT outlet with a ball valve for positive shutoff.

Installation and Setup Guide
Proper installation is the single most important factor in the long-term performance of the 110 Gallon Full Drain Cone Bottom Inductor Tank. A correctly installed tank will deliver years of trouble-free service. A poorly installed tank — sitting on uneven ground, exposed to point loads, or without proper support — can fail prematurely regardless of build quality.
Site Preparation
Start with site selection. Choose a location with good drainage that keeps water from pooling around the base. The tank needs a level surface of compacted gravel or concrete. Remove all rocks, roots, debris, and sharp objects from the pad area. The surface must be flat within 1/4 inch across the full diameter of the tank. An uneven foundation creates stress concentrations in the tank wall that accumulate over thousands of fill cycles.
Placement and Connections
Leave a minimum of 12 inches of clearance on all sides for inspection access, plumbing connections, and maintenance. Position the outlet fitting where your plumbing run is shortest — every additional foot of horizontal pipe adds friction loss and potential leak points. Use flexible connectors (not rigid pipe) for the first 12 inches from any tank fitting. Polyethylene tanks expand and contract with temperature changes, and rigid connections will crack or pull the fitting loose.
Venting
Every closed tank needs proper venting. As liquid flows out, air must flow in — otherwise vacuum pressure can collapse the tank walls. As liquid flows in, air must flow out — otherwise pressure can bulge or rupture the tank. A simple screened vent fitting in the lid handles both directions. For chemical storage, use a pressure/vacuum relief vent rated for the specific chemical being stored.
Maintenance and Long-Term Care
Polyethylene tanks are inherently low-maintenance, but "low" does not mean "zero." A basic inspection routine catches small problems before they become expensive failures.
Quarterly Inspection Checklist
- Visual inspection: Walk around the tank and look for bulging, discoloration, cracks, or weeping at fittings. Poly tanks telegraph stress before they fail — a bulge means something is wrong with the foundation or the liquid is exceeding the rated specific gravity.
- Fitting check: Hand-tighten all threaded connections. Polyethylene creeps under sustained pressure, and fittings can loosen over time. Do not use pipe wrenches on poly fittings — hand tight plus one-quarter turn is the limit.
- Foundation check: Verify the pad is still level and the tank hasn't shifted. Look for erosion, settling, or washout around the base.
- Vent check: Confirm the vent is clear and the screen isn't clogged with debris or insect nests. A blocked vent is the most common cause of tank deformation.
Cleaning
For water storage tanks, drain and flush annually. Sediment accumulates at the bottom and can harbor bacteria. Use a food-grade sanitizing solution (1/4 cup unscented household bleach per 15 gallons of water), let it sit for 2 hours, then drain and flush until the chlorine smell is gone. For chemical storage, follow the chemical manufacturer's guidelines for cleaning and decontamination before switching chemicals.
UV and Weather Protection
These tanks include UV stabilizers compounded into the resin, but no UV additive lasts forever. If the tank is in direct southern sun exposure for more than 8 hours per day, inspect the sun-facing side annually for chalking or color fading. A simple shade structure or reflective wrap extends service life significantly in extreme UV environments like the Desert Southwest.
Alternatives and Comparisons
The 110 Gallon Full Drain Cone Bottom Inductor Tank is one of several 110-gallon options available. Understanding the differences helps you pick the right tank for your specific application rather than settling for the first option you find.
Cone Bottom vs. Flat Bottom: Cone bottom tanks allow complete drainage without tilting or pumping. The trade-off is you need a stand, which adds height and cost. If your application doesn't require 100% drainage between batches, a flat-bottom tank is simpler and cheaper.

Frequently Asked Questions
How long will the 110 Gallon Full Drain Cone Bottom Inductor Tank last?
Under normal conditions with proper installation and maintenance, you can expect 15 to 20 years of service life. The UV-stabilized polyethylene resists degradation from sunlight, and the seamless rotomolded construction eliminates weld failures. Actual lifespan depends on chemical exposure, UV intensity, temperature cycling, and whether the tank was installed on a proper foundation. Tanks used within their rated specific gravity and temperature limits consistently reach or exceed the 15-year mark.
What chemicals can I store in this tank?
This tank is rated to 1.5 specific gravity and handles most agricultural chemicals, fertilizers, herbicides, pesticides, and industrial cleaning solutions within that density range. It is FDA approved for potable water and food-grade liquids. However, it is NOT suitable for gasoline, diesel, solvents, or any flammable liquid. Always check the chemical compatibility chart before storing a new chemical — polyethylene is resistant to most acids and bases but can be damaged by certain hydrocarbons and oxidizers.
What kind of foundation does a 110-gallon tank need?
A full 110-gallon tank at 1.5 SG weighs approximately 1,420 pounds. A level surface of compacted gravel or concrete works well. The critical requirement is that the surface must be flat and free of rocks or debris. An uneven foundation is the number one cause of premature tank failure.
Does this tank come with a warranty?
Norwesco backs this tank with a manufacturer warranty against defects in materials and workmanship under normal use conditions. The warranty covers manufacturing defects — cracks, pinholes, material failures, and fitting defects that are present from the factory. It does not cover damage from exceeding the rated specific gravity, improper installation, chemical attack from incompatible substances, or physical impact damage. Keep your receipt and installation photos for warranty claims.
Can I install this tank underground?
No. This is an above-ground storage tank. Polyethylene vertical tanks are not engineered to withstand the hydrostatic pressure of surrounding soil. Burying this tank would void the warranty and risk catastrophic collapse. If you need underground storage, look at our underground cistern and septic tank categories — those are specifically engineered with ribbed walls and reinforced construction to handle burial loads.
Buying Considerations
Before ordering the 110 Gallon Full Drain Cone Bottom Inductor Tank, verify three things: first, measure your installation space to confirm the tank dimensions fit with clearance for plumbing and access. Second, confirm your stored liquid's specific gravity is within the tank's rating — overfilling or storing liquids heavier than the rated SG voids the warranty and risks structural failure. Third, plan your freight — tanks this size ship via LTL freight on a pallet. You'll need a way to unload at your site — a loading dock, forklift, or the driver can set it at the tailgate with a liftgate delivery (request liftgate when ordering).
