## Overview

The RomoTech 82123919 is a rugged 50-gallon horizontal square water tank made in the USA from UV-stabilized, medium-density polyethylene. Designed for non-flammable liquids, it features clear gallon/liter markings, an oversized 5.5" lid, a 3/4" NPT outlet for quick fill and drain, and molded tie-down channels for secure transport. Ideal for agricultural, RV, and mobile applications, it resists rust, corrosion, fading, and cracking, ensuring dependable outdoor performance.

## Description

In Indiana, a charge of medium‑density polyethylene enters a rotational mold and emerges as a precise 50 gallon water tank—a horizontal square reservoir designed for everyday reliability. The natural, translucent wall lets operators verify fluid level instantly, while molded gallon and liter markings provide an exact read. Outdoors, UV‑stabilized poly resists fading and warping; in service, it won’t rust or corrode. A 5‑1/2" lid (5" opening) and easy‑tighten cap simplify refills, and a built‑in bulkhead fitting with a 3/4" NPT outlet makes fast work of draining, siphoning, or hose connection. Molded tie‑down channels accept saddle straps so this portable water tank rides securely as a truck bed water tank or trailer water tank, ready for farm chores, job sites, and water tank for car detailing setups. Rated for non‑flammable liquids to 140°F, it serves confidently as a potable water tank, a rugged water storage tank, or an RV water tank for extended trips. Made in the USA, it’s engineered for cleanability, durability, and dependable performance wherever you need compact capacity and square‑profile stability.

Review: 50 gal water tanks for fresh water delivery and wast disposal - I use this tank to bring fresh water to our RV and I use a second tank to remove wast from the RV. The tanks are well made and a good value. Be careful to have a good pickup location when delivered, these takes are big. It took a few weeks to get them. I would make a few changes to the tanks that would fit my use case. Make the tanks 1.5" lower. I have the two tanks side by side in the bed of my pickup truck. I had to shave off the fins on the black screw in cap on the top of the tanks so I could place the flat rigid pickup bed cover on. I would also place the tank fill port a bit lower so there is less water in the bottom of the tank after it's drained. I got around this by screwing a right angle GHT thread hose adapter on the inside of the fill port of the tank and then pointing the adapter right angle face down. I hooked a $60 12 volt Seaflow SFDP1-030-045-33 pump on it. It now drains the tanks almost dry. I also placed the tanks on a 1/2" board at the front of the tank, elevating the front to drain it better. I will include a picture but understand this is not completed. I will end up with two pumps mounted in the bed of the truck wired to the battery with switches on the dashboard for each pump. I am now working on installing a macerator (Jabsco model 18590-2092) on the RV that will pump the wast to the 50 gal wast tank. One important part is the (BANJO Reducing Coupling, 1 1/2 X 1 In Fpt, Poly). I have not got this part yet but I think it will allow me to connect the macerator to a 1" pipe that will connect to a 1" port I will install on the RV dump tube. I will run a hose from the pump wast outlet to the wast tank in the pickup. I think the whole thing will cost less that $600. Now I will no longer need to pull my travel trailer to get fresh water or to dump wast. I use the pickup truck to do the transfer. In the picture notice I have wired the two take to the bed of the pickup with steel cable and turn buckles. I am a full time RVer so I went to the local post office and set up (with out cost) a general delivery account where desertcart can deliver. I should make a few other points, the upper port on the top of the back side of the tanks I cut my self. I bought the gray threaded port fittings from Az as well. If I were doing the again I think I would put the ports I cut in the take on the top near the back instead on on the back side this is because, you will notice I run the city water through a blue RV water filter before the fresh water enter the tank this filter removed the chlorine so we add a table spoon of Chlorox is no different then the chlorine used to chlorinate drinking water. I also purchase a low cost chlorine testing kit and test the chlorine level after we pump the water into the RV fresh water tank. By placing the port on the top of the tank it would make it easier to pour the chlorine into the tank. I could remove the large black cap form the top the take and put the chlorine in there but found it easier to not fold back the pickup bed cover that farther than shown in the picture.
Review: Quality!!! Exceeded my expectations! - This tank was purchased to fill stock tanks for cattle. I have had this product for over a year, have hauled in in the back of a side-by-side in all weather conditions, stacked up on top of pallets (so that it the drain is higher than the tailgate), and driven across the farm which is not smooth terrain. We added a drain pipe with a shut off valve. This tank has HELD UP to the abuse of the farm! I am more than amazed at the quality of this tank.

### ⭐⭐⭐⭐⭐ Good capacity, portable
*by U***0 on October 28, 2025*

Fits nicely on the back of my side by side and the 55 gal capacity works well. If you’d rather not pull a gallon at a time. I would highly recommend the addition of a transfer station. For a couple hundred more, adding one pmade this tank even better for us.
