Introduced by Rep. Romeo S. Momo, Sr.

EXPLANATORY NOTE

The serious impact of Climate Change is imminent and dangerous, including, but not
limited to super-typhoons and severe flooding together with other rain-related
disasters. This is further aggravated by the country's natural vulnerability to disasters.

Itis a State policy to provide protection forthe safety of lfe and limb ofthe Filipino
people against natural and man-made calamities.

Thus, it is the intent of this measure to require all new subdivisions, condominium
communities, malls, government institutions, central business districts, information
technology parks, and other vital public establishments to construct rain harvesting
facility to pre-empt floods caused by incessant and continuous heavy rains and storms
on one hand, and to provide adequate source of household water on the other. With
similar intent, spirit and purpose to the existing proposed measures, albeit limited to
some areas only, this proposed measure intends to cover the entire Philippines so as
to achieve maximum nationwide awareness and benefit.

The immediate passage of this bill is therefore most earnestly sought.
