SPAS vs. POOLS
A spa is a good water-saving alternative to a residential swimming pool. While the average residential pool loses over 22,800 gallons of water per year due to maintenance refill, backwash, and evaporation, a spa generally loses less than 6,000 gallons in that time period.

SAFETY COVERS
The best way to conserve your spa water is to install a safety cover. Safety covers have numerous benefits: they will protect children and animals from the water; keep the water cleaner and in chemical balance; prevent 70 percent of temperature losses; and reduce evaporation losses by as much as 95 percent.

DRAINING YOUR SPA
Drain hot tubs only when necessary, not more than once every three to six months. Proper maintainenance can help you lengthen the periods between draining. Refrain from adding chemicals for two to three days before draining the spa, then use the drained water on your outdoor plants.

...AND OTHER TIPS
Many of the water-saving tips that apply to swimming pools are also applicable to spas.
