ICON Technologies Limited RV Holding Tanks & Waste Treatment Systems

ICON Technologies RV Holding Tanks & Waste Treatment Systems

When it comes to replacing or upgrading the waste management plumbing in your RV, few decisions matter more than the quality of your holding tank. ICON Technologies Limited RV has built a well-earned reputation as a go-to source for aftermarket RV holding tanks, combining North American manufacturing, rigorous certification standards, and an extensive lineup of sizes and configurations that cover virtually every coach on the road. Explore the full Holding Tanks & Waste Treatment Systems category to find the right fit for your rig.

Built for the Road: ABS Construction & Solvent-Welded Seams

Every ICON Technologies waste holding tank starts with a foundation of high-impact ABS plastic — a material chosen specifically for its resistance to cracking, corrosion, and the relentless vibration of highway travel. The thermoformed construction process produces tanks with a laminated top layer for added strength, while all seams are solvent-welded and fitted with a 1¼" mounting flange for a secure, leak-resistant installation. These tanks are engineered to withstand the bumps and jolts of the road, making them a reliable long-term solution rather than a short-term fix.

Six Drain Styles for Every Plumbing Configuration

One of the most distinctive aspects of ICON's waste holding tank lineup is its sheer configurability. The HT-series tanks are available in six distinct drain styles — including center end drain (ED), side drain (SD), recessed drain (RE), left end, right end, and bottom drain configurations — so owners can match the tank to their coach's exact plumbing layout rather than making compromises. Capacities range from single-digit gallon compact tanks all the way to models well over 50 gallons, ensuring a proper fit whether you're in a small travel trailer or a large Class A motorhome. Notable HT-series models include the HT192-ED (54 gal.), the HT241-SD (43 gal.), the HT152-RE (31 gal.), and the compact HT400-ED (8 gal.), among many others.

4-Level Sensors & Standard 3" Spigot Fitting

Every ICON holding tank ships with four built-in level sensors pre-installed, giving RV owners real-time awareness of their black or grey water levels — a critical feature for dry camping and boondocking where unexpected overflows simply aren't an option. A standardized 3" spigot fitting comes standard on all tanks, streamlining the connection to your existing plumbing and reducing installation time. ABS polymer adhesive and additional fittings are also available separately to complete the job.

Dual-Use: Black Water & Grey Water

ICON's waste holding tanks are designed for dual-use flexibility. They handle both black water and grey water applications — meaning the same tank can collect toilet waste or serve as a grey water tank collecting runoff from sinks and showers. This versatility makes them particularly useful when replacing a damaged tank or reconfiguring a coach's plumbing system.

IAPMO Certified & Made in North America

ICON Technologies holds certifications to IAPMO TS 2 and CSA B45.6 standards, two of the most recognized benchmarks for quality and safety in recreational vehicle plumbing. Every aspect of production is governed by a Quality Management System, and all tanks are manufactured in North America. A two-year limited warranty backs each tank, reflecting the brand's confidence in its own product.
