Waterless Urinals · Zerodor

Not a Drop to Flush. Not a Whiff of Odour.

Zerodor waterless urinals save up to 1.7 lakh litres of water per urinal every year and keep washrooms fresh, with a small mechanical valve that needs no water, cartridge or chemicals. Your existing urinals can be converted.

What You Gain

Water saved from the first use.: Every flush you no longer make is water kept in the supply.
Less to go wrong.: No flush valves, sensors or supply pipes to repair.
Works where water is unreliable.: Washrooms stay usable even when the supply is short.
Converts what you have.: Existing urinals are converted with a retrofit kit that replaces the waste coupling.

The cost of a flush

One Urinal. 15 Water Tankers a Year.

A busy flush urinal can send about 1.5 lakh litres of fresh water down the drain every year, only to carry urine that would flow away on its own.

1.5 lakh litres a year for a busy urinal, shown as 10,000-litre tankers. Zerodor puts the saving at 57,000 to 1,70,000 litres per urinal a year.

15tankers a yearEach drop is one 10,000-litre tanker.

Myth vs fact

Why We Still Flush

Myth~~A urinal needs water to stay clean.~~

Urine is about 95% water. It flows down by itself.

Myth~~Without a flush, it will smell.~~

The smell is ammonia from the drain line. Seal the drain and it stays there.

Myth~~Waterless means buying cartridges forever.~~

A mechanical valve has nothing to refill or replace.

The science, simply

The Smell Isn't the Urine. It's the Drain.

So instead of rinsing the bowl with water, we close the drain.

Urine flows inAbout 95% water, it drains on its own.
A ball valve opens, then closesIt lifts as liquid passes and drops back to seal.
Odour stays belowAbout 98% of urinal smell comes from the drain line.

How it compares

Three Ways to Run a Urinal

Compared	Zerodor mechanical valve	Cartridge urinal	Flush urinal
Water per use	None	None	1 to 4 litres
Your existing urinals	Converted with a retrofit kit	Needs a special pan	Already fitted
How odour is stopped	Mechanical seal on the drain	Chemical layer in a cartridge	Water held in the trap
Running cost	Nothing to replace	Cartridges, again and again	Water, plus valve and sensor repairs
Chemicals	None	Yes	None

Retrofit

Keep Your Urinals. Lose the Flush.

Most washrooms don’t need new pans. We convert the ones you already have.

Fitted in placeA retrofit kit replaces the waste coupling under the urinal.
No new plumbingNo flush pipes, sensors or power to add.
Your staff, shown onceDaily cleaning, and a 15-minute deep clean twice a week.

Questions

Do waterless urinals smell?

Not when they are cleaned as recommended. The sealed trap stops odour coming back from the drain.

What does cleaning involve?

Daily cleaning, and a 15-minute deep clean twice a week. No cartridge to replace.

How much water will we save?

Zerodor puts it at 57,000 to 1,70,000 litres per urinal a year, depending on how often it is used and the flush it replaces. The cost is typically recovered in about six months. The real figure depends on how many people use each urinal; we estimate it for your site.

Can our existing urinals be converted?

Yes. A retrofit kit replaces the waste coupling of an existing urinal, so it works without water.
