Most of the water used in bathrooms can easily be reused. Looking at the broader picture, bathroom water can be classified into two types, Greywater, and Blackwater.
Greywater is water that is normally recycled or reused. This water can be used for a number of household activities like washing the car, the driveway, and most importantly gardening.
This water is generally safe as it doesn’t contain pathogens. All you need to do is strain this water to remove impurities and put it to use.
On the other hand, black water is the water used or generated out of toilets. This water is not fit for recycling. Blackwater is generally let into a sump and cannot be reused to water gardens.

3. Alter plumbing if needed
The second most important factor when it comes to reusing bathroom water for gardening is altering the plumbing. Reusing bathwater becomes easier when you have an automated system.
Once a special plumbing system is installed the process of reusing water plumbing that plays a significant role becomes simpler.
But, in most households, the original plumbing is concealed. This makes it difficult to make alterations and integrate a new system. Alterations or additions done to the original system in such cases can get expensive.

Therefore, when it comes to plumbing in relation to reusing bathroom water for gardening, you need to make the choice if you want to invest in a full-fledged plumbing system or alter the existing system.
Both the options differ in terms of cost and the amount of time it will take. Both these options have their own pros and cons and we suggest you look at your requirements closely before taking a call.

Another way to recycle bath water and to make the water usable in gardens is by installing a purification plant. This will ensure that the bathroom water regardless of the products used is safe to water gardens.

How to collect bath water for garden manually?
When we say draining the water manually, we do not mean using a bucket to empty the tub. This method is a little time-consuming but works well if you do not want to alter the plumbing. Or if you are not so sure if you want to go through the reusing process altogether.
Manual draining of bathwater is simple all you need is a Fountain pump for about 90 – 100 gallons. These pumps are available locally at about $10 and work really well when it comes to draining tubs. Attach a pipe to the fountain pump and secure the joint. Once that’s done you need to plug the pump in and let it do it magic.
Dip the fountain pump in the tab and secure it at the bottom. These pumps normally come with rubber suction cups that help fasten them to the bottom. Once the pump is switched on it will start pumping water into the pipe.
Tip: See that the pipe is long enough to carry the water to either your plants or to the storage tank.
