HOUSE BILL NO. _______ 
Introduced by HON. GUSTAVO S. TAMBUNTING 
AN ACT 
TO REQUIRE ALL GOVERNMENT BUILDING CONSTRUCTION TO HAVE RAIN 
HARVESTING FACILITY AND FOR OTHER PURPOSES 
EXPLANATORY NOTE 
Water is one of the basic elements for survival. We use it for various purposes such as drinking, 
cleaning, taking a bath, washing clothes, and a lot of other things. It is a very valuable resource 
that we have taken for granted over the years. 
The advent of climate change has certainly affected the weather patterns not only in the 
Philippines but around the world. Polar ice caps are melting, heat indices have significantly 
increased and countries experience extreme weather conditions – from torrential rains that cause 
massive flooding, to dry spells that go on for months on end.  
With our continuously growing population, our need for water will also increase. And with this in 
mind, the undersigned proposes this bill to help conserve water and to equip our buildings with 
facilities that will enable us to cope with the changing times. Especially in the mid-rise housing 
and relocation projects of the National Housing Authority, having rain harvesting facilities will 
greatly help lessen the problem of water sources at the same time help in conserving the 
environment.  
It is for these reasons that the passage of this bill is being sought by the undersigned.
