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

2
00:00:03,600 --> 00:00:07,960
Speaker 1: where smart happens. Hi Am Marshall Brain with today's question,

3
00:00:08,400 --> 00:00:11,280
Speaker 1: why are they replacing all of the toilets in this

4
00:00:11,360 --> 00:00:16,120
Speaker 1: apartment complex? It's true many cities have conducted a massive

5
00:00:16,200 --> 00:00:20,040
Speaker 1: drive to replace older toilets with new water saving models.

6
00:00:20,120 --> 00:00:23,520
Speaker 1: Here's why. A family of four can consume something like

7
00:00:23,640 --> 00:00:27,480
Speaker 1: three four hundred gallons of water per day on things

8
00:00:27,520 --> 00:00:32,360
Speaker 1: like bathing, cooking, drinking, laundry, and dishwashing. Old toilets use

9
00:00:32,400 --> 00:00:36,640
Speaker 1: about five gallons or twenty leaders per flush. When you

10
00:00:36,680 --> 00:00:39,800
Speaker 1: consider that a normal person flushes a toilet seven or

11
00:00:39,840 --> 00:00:42,440
Speaker 1: so times a day, you can see that a family

12
00:00:42,479 --> 00:00:45,360
Speaker 1: of four consumes more than a hundred and forty gallons

13
00:00:45,360 --> 00:00:49,479
Speaker 1: of water per day flushing alone. Depending on the article

14
00:00:49,560 --> 00:00:53,440
Speaker 1: you're reading, the water consumption of toilets represents between thirty

15
00:00:53,479 --> 00:00:56,360
Speaker 1: and fifty percent of the water consumed by a household

16
00:00:56,360 --> 00:01:00,240
Speaker 1: each day. The new toilets installed in your apartment use

17
00:01:00,360 --> 00:01:04,560
Speaker 1: one point six gallons or six leaders per flush. If

18
00:01:04,600 --> 00:01:08,320
Speaker 1: you replace those five gallon per flush toilets with these

19
00:01:08,400 --> 00:01:12,040
Speaker 1: new one point six gallon per flush toilets, you save

20
00:01:12,080 --> 00:01:15,560
Speaker 1: a huge amount of water. Something like a hundred gallons

21
00:01:15,600 --> 00:01:19,200
Speaker 1: per day per household for a city. A big reduction

22
00:01:19,280 --> 00:01:22,120
Speaker 1: like that means that you can delay the construction of

23
00:01:22,160 --> 00:01:25,800
Speaker 1: new reservoirs and new sewage treatment plants. That's a huge

24
00:01:25,840 --> 00:01:29,560
Speaker 1: incentive to replace all the old toilets. Do you have

25
00:01:29,600 --> 00:01:33,320
Speaker 1: any ideas or suggestions for this podcast? If so, please
