Speaker 1: Welcome to brain Stuff from how stuff works dot com

2
00:00:03,600 --> 00:00:14,440
Speaker 1: where smart Happens. Hi Am Marshall Brain with today's question,

3
00:00:14,880 --> 00:00:17,760
Speaker 1: why are they replacing all of the toilets in this

4
00:00:17,840 --> 00:00:22,600
Speaker 1: apartment complex? It's true many cities have conducted a massive

5
00:00:22,680 --> 00:00:26,520
Speaker 1: drive to replace older toilets with new water saving models.

6
00:00:26,600 --> 00:00:30,000
Speaker 1: Here's why. A family of four can consume something like

7
00:00:30,120 --> 00:00:33,960
Speaker 1: three four hundred gallons of water per day on things

8
00:00:34,000 --> 00:00:38,839
Speaker 1: like bathing, cooking, drinking, laundry, and dishwashing. Old toilets use

9
00:00:38,880 --> 00:00:43,120
Speaker 1: about five gallons or twenty leaders per flush. When you

10
00:00:43,200 --> 00:00:46,280
Speaker 1: consider that a normal person flushes a toilet seven or

11
00:00:46,320 --> 00:00:48,920
Speaker 1: so times a day, you can see that a family

12
00:00:48,960 --> 00:00:51,839
Speaker 1: of four consumes more than a hundred and forty gallons

13
00:00:51,880 --> 00:00:55,960
Speaker 1: of water per day flushing alone. Depending on the article

14
00:00:56,040 --> 00:00:59,920
Speaker 1: you're reading, the water consumption of toilets represents between thirty

15
00:01:00,160 --> 00:01:03,360
Speaker 1: fifty percent of the water consumed by a household each day.

16
00:01:04,040 --> 00:01:07,319
Speaker 1: The new toilets installed in your apartment use one point

17
00:01:07,440 --> 00:01:11,640
Speaker 1: six gallons or six leaders per flush. If you replace

18
00:01:11,760 --> 00:01:15,400
Speaker 1: those five gallon per flush toilets with these new one

19
00:01:15,440 --> 00:01:19,199
Speaker 1: point six gallon per flush toilets, you save a huge

20
00:01:19,240 --> 00:01:22,600
Speaker 1: amount of water. Something like a hundred gallons per day

21
00:01:22,680 --> 00:01:26,160
Speaker 1: per household for a city. A big reduction like that

22
00:01:26,480 --> 00:01:29,520
Speaker 1: means that you can delay the construction of new reservoirs

23
00:01:29,520 --> 00:01:32,959
Speaker 1: and new sewage treatment plants. That's a huge incentive to

24
00:01:33,000 --> 00:01:36,959
Speaker 1: replace all the old toilets. For more on this and
