Quite a bit of water is wasted every year in the summer, mostly through outdoor watering, but there are things you can do to help conserve water, while still maintaining a beautiful lawn.
According to the TWDB, only one inch of water a week is needed to keep most Texas grasses healthy, so timing your sprinklers to deliver just the right amount will save both water and your landscaping.
You can determine how long your sprinklers need to be on to deliver an inch of water by placing straight-edged cans at different distances from your sprinklers, then measuring how long it takes to get an inch of water in each can.
Other tips to conserve water in the summer months are:
Avoid losing water to evaporation by watering in the early morning or late evening
- Install rain shut-off devices
- Check Sprinkler heads regularly
- Plant water-efficient or native plants
- Never water on windy days
- Buy a rain barrel or cistern
According to the USGS, water use in the home derives mainly from the following activities:
A full tub is about 36 gallons.
2 gallons per minute. Old shower heads use as much as 5 gallons per minute.
<1 gallon, especially if water is turned off while brushing. Newer bath faucets use about 1 gallon per minute, whereas older models use over 2 gallons.
4 to 10 gallons/load, depending of efficiency of dishwasher
Dishwashing by hand:
20 gallons. Newer kitchen faucets use about 2.2 gallons per minutes, whereas older faucets use more.
25 gallons/load for newer washers. Older models use about 40 gallons per load.
3 gallons. Most all new toilets use 1.6 gallons per flush, but many older toilets used about 4 gallons.
Glasses of water drunk
8 oz. per glass (did you remember to drink your 8 glasses of water today?)
5 to 10 gallons per minute
However, there are things the average person can do to conserve water in the home. The following list is from the TWDB:
