Waterless Restroom Innovations – How Urinup™ Eliminates the Problem Instead of Managing It

For facility managers, hotel and venue operators, and senior care administrators

Most waterless restroom solutions are built around the same fundamental assumption: waste needs to be stored, contained, and managed. Cartridges slow the odor. Chemicals neutralize the buildup. Maintenance schedules keep the problem tolerable.

Urinup™ by CapaciFlow™ starts from a different assumption entirely. In Funnel Mode – the primary deployment configuration for high-throughput venues – there is no storage. Liquid flows by gravity directly into an existing toilet or drain. Continuously. Cleanly. Without contact. When there is nothing to store, there is nothing to manage.

This article explains how Urinup™ approaches waterless sanitation differently, what that means for your venue, and where it delivers the most impact.

Why Waterless Matters – The Short Version

Traditional urinals use 1–4 liters of drinking water per flush. In a stadium, arena, or busy venue, that adds up to hundreds of thousands of liters per event season. Waterless solutions cut that to zero.

Beyond water savings, waterless systems support:

ESG and sustainability reporting – documented water reduction with zero plumbing infrastructure changes
Cost reduction – no water or sewer charges per use, simplified maintenance
Flexibility – deployment where plumbing is unavailable, impractical, or cost-prohibitive
Hygiene – less flushing means fewer aerosols, less splash, cleaner surfaces

Urinup™ delivers all of these. But the way it achieves them is fundamentally different from a fixed waterless urinal or a cartridge-based system.

How Urinup™ Works – Dual Mode Explained

Every Urinup™ unit operates in one of two modes. The mode is selected based on the venue, the event, and what infrastructure is available.

Funnel Mode – Zero Storage, Zero Odor Cycle

In Funnel Mode, Urinup™ connects directly to an existing toilet or floor drain. The user never touches the fixture. Liquid flows by gravity through clear PVC tubing and exits continuously into the receiving drain. There is no holding tank. There is no accumulation. There is no odor cycle, because the condition that causes odor never forms.

This is the primary configuration for high-throughput venues: stadiums, arenas, festivals, outdoor events, and construction sites. It is also the configuration that most directly answers the question every facility manager asks first: “What about the smell?”

The answer with Urinup™ in Funnel Mode is not “we manage it.” The answer is: there is nothing to smell because there is nothing stored.

Tanked Mode – Fully Off-Grid

In Tanked Mode, Urinup™ operates as a fully self-contained unit. The collector tank captures liquid waste, and the unit requires no connection to existing infrastructure whatsoever. This makes it ideal for remote sites, temporary expansions, or any location where a drain or toilet is not nearby.

When the tank reaches capacity, a single operator tips the unit over an existing toilet and opens the gravity drain valve. Zero contact. Zero mess. One person. One move.

Three Editions – One for Every Deployment

Urinup™ is available in three dual-mode configurations, each designed for a specific use context.

Single Gentleman Edition – One user position. Compact footprint. Ideal for tight corridors, backstage areas, hospitality suites, and single-user deployments.

Double Gentleman Edition – Two simultaneous user positions separated by a full-height central privacy divider. Doubles throughput with the same operator footprint. Designed for construction sites, stadium concourses, and outdoor events.

Double Gentleman Edition – Multi-user innovation for high-throughput… remaining info is on hidden mode due to pending IP filling.

<!– HIDDEN: Double Ladies Edition paragraph retained for internal reference. Double Ladies Edition — Multi user innovation for high-throughput, dignified use in busy venues. Note: Undergoing patent filing.. Two simultaneous user positions with ergonomic seated design and full privacy divider. Brings the same throughput advantage and dignity of access to female users at venues and events where restroom lines are longest. –>

All three editions roll on lockable wheels and are operated by a single person.

Beyond Odor Control: Eliminating the Condition That Causes It

The standard waterless restroom conversation goes like this: sealed cartridges, barrier liquids, antimicrobial surfaces, airflow management. All of these are solutions to a problem created by storing waste.

Urinup™ in Funnel Mode bypasses that conversation entirely. Here is a direct comparison:

Traditional Waterless Urinal	Urinup™ in Funnel Mode
Stores waste in cartridge or trap	No storage – continuous gravity drain
Requires cartridge replacement on schedule	No cartridge – nothing to replace
Odor managed via barrier liquid	No odor cycle – no stored waste
Fixed installation	Rolls on wheels – repositioned in seconds
Single user position	Up to two simultaneous users
Plumbing connection required	Connects to any existing toilet or drain

For Tanked Mode, where waste is temporarily stored, Urinup™ does include an odor control device within the collector tank. But this is only relevant when operating off-grid – and even then, the collector is a sealed, closed system that is emptied by gravity drain with zero staff contact.

Where Urinup™ Delivers the Most Impact

Stadiums and Arenas

Restroom lines are the single biggest driver of in-venue complaint at sporting events and concerts. Urinup™ Double Gentleman and Double Ladies Editions connect directly to existing restroom drains or toilets via Funnel Mode, instantly doubling urinal capacity in any zone without plumbing work. No permits. No construction. No downtime.

Outdoor Events and Festivals

Porta-potties are the current default, and they are universally disliked. Urinup™ in either mode provides a cleaner, faster, more dignified alternative that can be positioned anywhere on site and repositioned between events by one person.

Construction Sites

Workers on active job sites have limited access to restrooms and limited time. The Double Gentleman Edition in Tanked Mode can be deployed anywhere on a worksite without infrastructure, then rolled to a restroom trailer for zero-contact emptying at the end of the day.

Hotels and Senior Living

In guest-facing environments, spill prevention and hygiene are the priority concerns. Urinup™ in Funnel Mode connects to an existing toilet in a guest bathroom or suite, eliminating the splash and misdirection that causes floor contamination – without modifying the room’s plumbing.

Remote and Off-Grid Sites

For locations where no drain or toilet is nearby – remote construction, outdoor venues, nature facilities – Tanked Mode provides fully self-contained sanitation that travels with the crew and empties into any standard toilet when convenient.

Implementation – What It Actually Takes

Deploying Urinup™ requires no construction, no permits for the unit itself, and no permanent modifications to your existing restrooms.

Funnel Mode setup: Position the unit near an existing toilet or floor drain. Connect the gravity drain line. Lock the wheels. One person. Under five minutes.

Tanked Mode setup: Position anywhere. Lock the wheels. No connections required.

Cleaning: The urinal top detaches for cleaning. All surfaces are smooth and non-porous. No cartridges to handle. No stored waste to contact.

Relocation: Unlock the wheels. Roll to the next position. Lock. Done.

For venue operators managing high-throughput events, this simplicity is the point. Urinup™ is not a facility upgrade that requires a contractor. It is a sanitation tool that one staff member can deploy, relocate, and empty in minutes.

The Waterless Restroom Conversation Has Been Missing This

Most waterless restroom innovation has focused on improving fixed infrastructure — better cartridges, smarter sensors, cleaner materials. These are incremental improvements to a system that still requires storage, still requires maintenance cycles, and still cannot be repositioned when the crowd moves.

Urinup™ approaches the problem from the other direction. Instead of improving how waste is stored and managed, it removes the storage requirement for the most common deployment scenario. In Funnel Mode, the unit is essentially a gravity-powered conduit, ergonomic intake, zero contact, continuous flow, clean exit.

For facility managers and venue operators evaluating waterless options, the question is not just “which cartridge system is best?” It is: “Do I need to store waste at all?”

For most high-throughput venues, the answer is no.
