For the record and I have said this many many many times. Half the energy our society expends is on pumps. Second, water is awfully cheap. Many people consider the next two things I will suggest as “parlor tricks”, but they are cheap and easy. One, buy and install a low flow shower head. They up the pressure of the water so you get a better shower using half as much water as normal.

Low Flow Shower Head: Oxygenics
Pros: Attractive design. Adapts well to different kinds of water pressure. Has a lever that adjusts water velocity. Oxygenates water.
Cons: Has a jet-like sound that some may find distracting. May reduce the temperature of your shower water a bit.
Price: $20-35
The Oxygenics SkinCare Showerhead is my favorite low-flow showerhead. It has a vigorous spray and it oxygenates the water quite well. It is a “self-pressurizing” showerhead, meaning it adapts to low or variable water pressure. It can deliver a great shower whether the water pressure is 20 psi (pounds per square inch) or 100 psi. It has a maximum flow rate of just 1.5 gallons of water per minute. It has a comfort control lever on the side to allow for the regulation of water velocity at the showerhead, allowing the user to select a spray ranging from brisk and stimulating to soft and gentle.

Low Flow Shower Head Review: HighSierra FCS Works Great
I have spent the last several weeks testing the HighSierra FCS-200 water saving shower head; it costs about $25, provides a great shower experience, uses only 1.5 gallons per minute (GPM) and I highly recommend it.
I have now done five low flow shower head reviews so far (sorry, no nude shower scenes in this one) and the HighSierra wins hands down on price and is a strong contender for the best feeling shower of those we have tried.
A water saving shower head can help you conserve water, and in particular hot water which means you’re also save energy.
The other very good water saving shower heads I tested are larger, and considerably more expensive. Don’t be deceived — the HighSierra model might look like those really cheapo, painful shower heads that they put in locker room showers. But HighSierra’s clever low flow design makes it really a totally different beast. Simple is good; the manufacturer claims that it is less likely to become clogged with mineral deposits, it’s very small, and solidly built.

Or install a toilet damn

Toilet Dams make your tank smaller by using plastic barriers that prevent water from running out when you flush. Your toilets are the largest water-wasters in your home. About 5-7 gallons of water are lost with every flush. Using one of these Toilet Dams you save 100’s of gallons of water per person per year and REDUCE SEWER FLOWS.
A standard dam can hold back one gallon of water. The Incredible Superbowl Toilet Dam holds back 2-3 gallons of water per flush.
Estimating about 10 flushes a day, that is a savings of up to 12,000 gallons a year.
Comes with a pack of 2.
