The Conventional/Centralized Treatment Method
Here are a few points on what we need to know
about this wastewater treatment method
3
The Conventional/Centralized Treatment Method
01 Central civic or municipalities usually use
this method of wastewater treatment.
4
The Conventional/Centralized Treatment Method
02 The treated water is just drained into nearby
oceans, rivers, lakes, and other such bodies of
water.
5
The Conventional/Centralized Treatment Method
03 Since it is an underground system, most if not
all the people in the community are unaware of
all the wastewater they are generating.
6
The Problems of Conventional/Centralized
Treatment Method
The notion of the negative impacts of this
wastewater treatment was only strengthened when
the following instances started happening
7
The Problems of Conventional/Centralized
Treatment Method
Cities and towns are bursting at the seam due
to the volume of sewage being generated and
increasing in geometric progression.
8
The Problems of Conventional/Centralized
Treatment Method
Many industries and micro-industries often have
wastewater that is more difficult to treat
compared to ordinary sewage.
9
The Problems of Conventional/Centralized
Treatment Method
03 There is an increasing awareness about the
impact of all forms of pollution on the current
and future generation of all living things on
this planet.
10
The Problems of Conventional/Centralized
Treatment Method
Plants make large surrounding areas of land
unlivable due to the odor and the breeding of
insects like mosquitoes in the vicinity, usually
around the pumping stations.
11
The Problems of Conventional/Centralized
Treatment Method
Municipalities are now unable to find enough
overground and underground space to increase the
size of the treatment plant to accommodate the
increase in sewage water volume.
12
The Problems of Conventional/Centralized
Treatment Method
More and more people are starting to have the
perception of the unjust work conditions of
sanitation workers, as these said work conditions
often have them working in filth.
13
The Problems of Conventional/Centralized
Treatment Method
The increase of cost on the installation of
sewerage systems as well as operating and
maintenance has made it hard for municipalities
to manage financially.
14
The Problems of Conventional/Centralized
Treatment Method
Sewage blockages cause a significantly bad odor
in the whole city or town, and the only way to
get rid of the odor is to clear the blockage.
15
The Problems of Conventional/Centralized
Treatment Method
There are also increasing costs in the aspects of
Conventional/Centralized Wastewater Treatment.
16
The Problems of Conventional/Centralized
Treatment Method
As water becomes an increasingly scarce resource,
dumping well-treated water in lakes, rivers or
other bodies of water has become a criminal act.
17
Considering the Decentralized STP Option
There are quite a number of advantages
communities can reap from Decentralized STPs, and
these advantages include the following
18
Considering the Decentralized STP Option
With the right technology and design, this
approach can result in the reduction or even
elimination of underground sewerage systems.
19
Considering the Decentralized STP Option
The plants are scalable, meaning we can keep
building plants based on the growing needs of the
community at any given time.
20
Considering the Decentralized STP Option
Decentralized STPs are known to have much lower
operating and maintenance costs.
21
Decentralized STPs are a fairly new trend that
many have not caught onto yet. However, it is
clear that this method can make great
contributions to the conservation of water and in
better quality treated wastewater.
