Responsible water conservation is critical to the survival of the human species on Earth. One of the best detailed posts explaining this can be read here:

This page cites a few great studies on water conservation and the future of our planet for our children.

 

As population continues to grow and impending global climate change brings new environmental challenges, water demand will also increase in the future. Indeed, research indicates water demand is currently exceeding supply, making conservation efforts crucial if we hope to maintain an adequate water source. Rolston St. Hilaire (2009) of New Mexico State University asserts, “The lack of water has the potential to jeopardize our food supply, disrupt fragile ecosystems, alter alliances among constituents, and threaten our way of life.” [29] Thus, to avoid the possibly catastrophic consequences of squandering our much needed water supply, the public must assume an active role in conservation. Helen Ingram (2009) of University of California-Irvine reports that following extensive studies on local, regional, and global water use, a team of scientists concluded that, “A crucial part of the path to water conservation involves paying close attention to the dimensions and scales that define how people interact with and understand water.”[30]

 

I lived in a home in 2015 and in this blog I am using the utilities as a case study for supporting factual figures. We had 2 adults and a 7 year old and a 3 year old.

There are aprox. 70 gallons in bath tub’s fill line.
We used half per bath… say 35 with 1.5 baths a day at 30 days …

We used aprox. 1575 gallons a month to bathe.
The Avg shower is 8 min but we took closer to 10 minutes.
We used a low flow 2 gpm (gallon per minute) shower head.

You should get one like these I link here if you do not have one yet.
We took 1.5 showers per day x 30 ….

We used Aprox. 900 rounded up to 1000 gallons per month to shower.

The Avg flush is 5 gal … say we avg 8 flushes a day x 30 …

I highly recommend using a composting toilet where possible. I also encourage you to read about how most of the coastal cultures use SALT WATER sewer systems rather then wasting their fresh drinking water.

Here is a link to some ideas for low flow toilet upgrades.

 

We use aprox. 1200/month to flush

The Avg hose flow with a spray handle or thumb press
Is 35 gal per minute and we water our garden 2 min day x 30 …

We use aprox. 2100/month to water our food

*if calculating a yearly amount this should be decreased by 25% to account for indoor green house watering during the winter.

We ran our faucets at 20% for aprox 5 min a day
7 gpm x 5 x 30 …

We used aprox 100-200 gallons a month via faucets

 

IN TOTAL we averaged 4-5000 gallons of water used per month.

 

In essence: start small. Changing your shower head to a low-flow alternative is a quick and easy way to start on the personal path to water conservation. Federal programs like the EPA’s WaterSense make low-flow shower heads accessible, while new technologies like water aeration devices and screw turbines give low-flow shower heads comparable pressure to the luxury of higher gpm heads. If you are building or remodeling a deluxe new bathroom, top end premium shower heads can meet your spa like needs. On the other hand, if you are attempting to retrofit your home to save money, simple add on kits make updating your shower head a logical, inexpensive option.

 

In Hawkins Texas, we are billed $11 per 1,000 gallons. How does this compare to your water provider?
