The Norwesco 1700 Gallon Black Vertical Storage Tank is a 1700-gallon polyethylene vertical built for bulk water and liquid storage where you need real capacity on a compact pad. The black resin and 1.5 specific gravity rating make it a workhorse for outdoor water storage, irrigation supply, fire-water reserves, and similar Norwesco vertical storage tank duty. If you are sizing for rural fire protection, our guide on fire-water reservoir tank design for rural and remote sites covers NFPA 22 sizing discipline and cold-climate freeze protection.
Will this Norwesco vertical work for my site?
This is a 1700-gallon vertical storage tank rated to a 1.5 specific gravity, meaning the wall is built to hold contents up to 1.5 times the density of water. Filled with water, the contents weigh about 14,178 lb; at the full 1.5 SG rating the tank is engineered to carry up to 21,267 lb of contents. Plan your pad and foundation around the higher number, not just the water weight - the support surface has to carry the maximum rated load, full, indefinitely. The footprint runs roughly 87 x 87 inches, which sets your minimum pad size, and the black exterior limits light penetration to slow algae growth in stored water. Confirm the overall height and orientation against the technical drawing on this page before you finalize pad clearance and overhead access, then use the Tank Sizing Calculator and the Tank Sizing Guide to verify this 1700-gallon size fits your draw rate and refill cycle.
Foundation and fitting configuration
A loaded vertical tank this size demands a flat, level, fully-supporting base. For above-ground installs, our guide on concrete pad sizing for above-ground polyethylene tanks walks through the ACI 360R-10 framework and where the ACI 318 boundary applies. For reclaimed and harvested supply, the industrial water reuse tank topology and rainwater harvesting first-flush diverter sizing guides cover quality-banded storage and inlet design. Inlet, outlet, and lid configuration are not yet published in this listing - the technical drawing on this page is the authoritative source for fitting locations and outlet details, and you can call 866-418-1777 to confirm inlet, outlet, and lid sizes before ordering any plumbing.
The mistake to avoid
The most common error on a tank this size is building the foundation for the water weight instead of the rated load. Size your pad for the full 21,267 lb maximum rated contents, set it dead level, and support the entire base - an unsupported or out-of-level base concentrates stress and shortens tank life. If you plan to store anything heavier than water, confirm the contents stay within the 1.5 specific gravity rating before filling; for heavier-content needs, call 866-418-1777 before you order.
This tank ships LTL freight from the nearest Norwesco plant - Sheldon, IA or Washington Court House, OH - quoted live to your ZIP code. Shipping from whichever of the two plants is closer to you shortens the LTL lane and typically trims freight versus a single-origin tank.
