WGH Permeable Pavement & Meandering Walkway
Looks like an unfinished driveway…
they are so cheap,
they cannot afford to cement the whole driveway…
• Why is the gravel loose?
• What is the use of the snake like path?
Cebu is experiencing the intrusion of salt water
into its water table,
but many people do not seem to realize
the gravity of this situation.
Ninety six percent 96% of water used in Metro Cebu
comes from ground water extraction.
Ground water is recharged when it rains.
However, rapid urbanization
has resulted in the concreting of sidewalks and driveways
causing the abundant run-off of rainwater
to flow straight to the sea
and preventing natural groundwater recharge.
Thus, the salt-water intrusion problem
will continue to worsen
unless we all cooperate
to find ways to stop or reverse
the precarious water situation of Metro Cebu.
For a time,
there was even talk
of piping in fresh water from Bohol,
however improbable that solution may be.
What are we doing about Cebu’s water situation???
In our own simple but effective way,
we know we are helping recharge the water table of Cebu.
Concreting a driveway
seals the ground
and prevents the absorption of water back into the water table.
By using a single sized gravel aggregate,
rain water can seep through the gravel
and return to the water table.
If only every business or home
would establish a groundwater recharging point,
the impending water crisis of Cebu may still be averted.
For almost 18 years,
we had a fully concreted driveway.
However, when we initiated the eco-renovations
of our building in 2008,
we boldly demolished it
to make way for a permeable pavement.
That expensive demolition decision
had the singular purpose
of allowing rainwater to percolate back into the water table.
￼￼We first experimented with replacing the concrete
with a permeable paver.
However, the pavers broke
because they could not bear the weight of the cars.
We replaced them with single sized gravel aggregates.
The driveway just in front of the hotel
is a unique design that immediately challenges common thinking.
￼￼￼￼￼￼￼￼￼￼￼￼￼￼￼￼￼￼￼￼￼￼￼￼￼￼￼￼￼￼￼￼￼￼￼￼￼￼￼￼￼￼￼￼The meandering path of our driveway
actually serves several purposes;
it keeps the gravel from being carried away
by the vehicles that drive through,
at the same time it serves as a walking path
for high-heeled pedestrians.
It also provides an interesting visual pattern
based on the natural path of a meandering river
that children and adults can enjoy tracing with their feet.
Our unfinished looking driveway-
is an example of a low-tech solution
to Cebu’s fresh water supply problem…
