The Cleanest City in the State !


  • Tiruchirappalli ranked as

    • 1st Cleanest City in the State

    • 6th Cleanest City in the Country

  • based on National Urban Sanitation Policy

Initiative Background – An Overview

  • As the city is the nerve center of the state, it draws a floating population including pilgrimages and tourists of about 2.00 lakhs, thronging the Central Bus Stand round the clock, throughout the year.

  • In general, people use the open space adjacent to the Bus Stand for urination, which creates health and environment hazard.

  • In order to ward off this menace, many urinals have to be constructed with Borewell, Motor pumpsets, Overhead Tanks which will also cave way for usage of plenty of water.

  • To solve this problem, 20 Nos. of Waterless urinals have been provided in central bus stand as a pilot measure

About Waterless Urinals

  • The waterless urinals are non-porous and designed to funnel virtually every drop of urine through the sealant layer in the cartridge and down the drain.

  • The sealant liquid is lighter than water and creates an airtight seal, so the urine passes through and is trapped.

  • Any urine in the bottom of the waterless urinal cartridge or drain is sealed from the restroom's atmosphere.

Technology & Water Saving

Cartridge Technology

Comparison Chart

Conventional Urials Vs Waterless Urinals


  • Reduce water consumption.

  • Energy savings on pumping water to OHTs for the use of flushing urinals.

  • Considerable reduction in carrying capacity of sewer lines by saving water.

  • Economical in comparison to flushed urinals

  • Simple and easy to maintain.

Facility at Central Bus Stand

The Corporation for the first time took an initiative to install twenty number of Waterless Urinal at Central Bus Stand on pilot basis.

The whole objective of the project was to prevent open urination on streets and develop a sustainable way of sanitation.

Waterless Urinals at Central Bus Stand

Challenges Faced

  • Unfamiliar Concept to the public.

  • Damages caused to the urinals by throwing bottles, hard substances etc., on the Cartridges.

  • Blockages in the Cartridges by Spitting, throwing cigarette buds etc., to the Urinals

Action taken for Successful Implementation

To sustain the initiative, frequent inspections were made by the Commissioner to encourage the public to utilize the facility.

The Public were sensitized about the usage of the Waterless Urinal through handbills, hoarding etc.,

Action taken for Successful Implementation

Stainless Steel Gratings are provided over Cartridges to prevent the damages.

Awareness created through continuous IEC Activities by posting care-takers.


  • Waterless urinals have saved approximately 4000 Liters per day, which will results in 15.00 Lakh liters of water savings per year.

  • Waterless urinals have considerably cut down the usage of power motors for pumping Water to OHTs, resulting in 2% of energy savings in power consumption for Water Distribution in Central Bus Stand.

  • Considerable reduction in carrying capacity of sewer lines by saving water used for flushing the urinals after every use.


  • From the pilot implementation we have understood that aesthetics of washrooms is one of the major factors for user to consider a toilet suitable for use.

  • Waterless Urinal due to it design science and odor blockage technology help maintain the aesthetics of washrooms.

  • Waterless Urinals are easy to install and maintain. It can also be installed at arid areas were we do not water supply, thus winning the limitation of remote installation.

  • The target science helps us maintain the floor dry and ready to use for next user. If waterless urinals are installed throughout the city it will result in huge water saving and will prevent open urination.
