How Much Water Does a Public Toilet Use Per Flush? Improving Efficiency
The best answer to answer this question is straightforward; public toilets use an almost same amount of water as home toilets per flush. The only difference is the number of people who use that toilet per day. The higher the number of public toilet users, it is perceptibly expected that more water will be used. However, there is one thing that every person should know when it comes to water usage in toilets. Different types of toilets use water differently per flush. This can be illustrated appropriately by comparing the oldest, older, newer, and the newest toilet models.
Let’s compare them briefly…
Toilets that were manufactured before 1980 use a large amount of water per flush, usually 5 to 7 gallons per flush. Those that were manufactured in the 1980s use about 3.5 gallons per flush. If you consider an old public toilet, definitely there is a high amount of water that goes to waste on a daily basis.
The toilets that were manufactured in the 1990s use a maximum of 1.6 gallons per flush. Some of the newer models, including which are being manufactured nowadays, use as little as 1.2 gallons per flush. The modern toilets that use the least amount of water per flush are known as water certified, but this may depend on which state or country you reside. In short, flushing toilets are highly efficient in water conservation. Interestingly, they provide a perfect flushing just as the old toilets.
How to Improve Efficiency in Public Toilets
Upgrade to Water Saving Toilets
Upgrading to modern water saving toilets is the biggest investment to carry out. You can choose to install dual-flush toilets, which are normally advocated by municipalities all over nowadays. If investing in a new dual-flush is too costly for your budget, there are dual-flush conversion kits available at retail prices – about $15 to $20 per kit. There are also toilet top sinks, which are perfect for public toilets. Once a person flushes the toilet, water is directed to a faucet for hand wash first before it drains into the toilet bowl.
Minimize Water Usage in Toilets
This may sound impractical, but in the real sense, it is possible. A simple method is to reduce the amount of water required to fill the tank after every single flush. Those people who provide public toilet services or working in any facility with public toilets can use a Fill Cycle Diverter, which diverts some water to the tank instead of filling the toilet bowl. So, the bowl will be refilled with water quickly, which in turn saves about half a gallon per flush. The displacement devices occupy the space in the tanks, hence reducing the amount of water required to fill it. On the other hand, a tank bank is another useful tool that can minimize water usage in public toilets. It clips onto the tank’s side and displaces about 0.8 gallons in every flush.
Advocating Less Often Flushing Habit
This method is very practical when it comes to public toilets where there are urinal sections for gents. Users should only use the urinal option for short calls instead of using toilets. After all, there should be a sticker prohibiting
flushing toilets after short calls. For the ladies, as they cannot use a urinal section like gents, the toilet keepers should ensure they flush the toilet in a timely manner to ensure tissue papers do not clog the drains.
Reuse Shower Water
For those facilities that offer both shower and toilet services, it is advisable to embrace reusing shower water. When a person enters a bathroom and opens the shower valve to allow the water to heat up, a significant amount of water goes to waste. Buckets should be placed in every bathroom, and then the users are informed to collect the cold water into those buckets. As someone takes a shower, some of the splashing water will also be collected into the buckets. After the shower, the bucket containing water should be picked and emptied into a tank outside the bathroom and then it is returned in the bathroom.
