Enterprises, koperasi, private enterprises, and / or
community groups that carry out the development of
drinking water supply systems ". The Verse 10 states
that "Organizers are individuals, community groups,
or institutions that obtain drinking water services
from the operator", so that to archieve the target of
drinking water supply based on the deviation between
the state budget and regional budget with RPIJMN is
through cooperation between the government and the
private sectors, such as; bank loans, Obligations,
Corporate Social Responsibility (CSR), Government
Investment Centers (GIC) and others. So that with
this alternative financing is expected to accelerate the
achievement of the target of the development of
drinking water supply in an area specifically.
SPAM in Manado City is currently managed
mostly by PT. Air Manado, some region in
Malalayang sub-districts are managed by UPTD AM,
while Mapanget sub-district is managed by PDAM
Manado and UPTD AM.
So far in drinking water management by PT. Air
Manado, PDAM Manado and UPTD AM, the level of
service to the public is still relatively low. This can be
seen from the coverage percentage of the area
services from the three managers of drinking water
supply is still low. The service coverage of PT Air
Manado on the range is still 27.52% to Manado City
population. The coverage of PDAM and UPTD AM
in Mapanget sub district is only 12.03% from 54,640
people, which is only 6,573 people. Based on these
percentages, SPAM services are still very small from
the MDGs target for urban residents. According in the
Manado City Spatial Plan in 2017 where Mapanget
sub district development has changed for its
designation, which is to become the central
development area of Manado City. The consequences
of that development are the many additional office
buildings, housing and commerce that certainly
accompanied by population growth which greatly
affects the level of drinking water needs.
Based on the above description in Mapanget sub-
district, it is necessary to develop a drinking water
supply system that is expected to achieve the needs of
drinking water both in terms of quality and quantity.
2 RESEARCH METHODOLOGY
The Methodology was started by collecting data, both
primary and secondary data through literature
studying, surveying, interview and filling out the
questionnaires. Furthermore, identification of the
determine feasibility factors of the SPAM is carried
out.
The next step is data analysis. The Both of data is
analyzed based on the feasibility factors. The
indicators of technical factor are source water and the
transmission system. The indicators of social factors
are service area, population development, total usage,
desire to subscribe of drinking water. The indicator of
institutional factor is organization of SPAM. The
output of this stage is the feasibility of drinking water
supply systems technically, socially and
institutionally.
The last Stage is economical and financial
analysis based on technical, social and institution
factor. The indicators are the all of cost, the benefit
and price of drinking water. The feasibility
investment determined IRR, NPV, BCR, and PP.
3 RESULTS AND DISSCUSION
3.1 Identification and Analysis of
Technical Feasibility Factors
Analysis of water source in Mapanget sub district
based on SPAM Manado and SPAM Bimantara
Master Plan consists 3 water sources that are Paniki
river, Tondano river and Kuwil reservoir. Paniki river
have used for some region in Mapanget sub district
but did not supply all the need. So the focus of the raw
water source on Tondano river also used for electric
source and Kuwil reservoir.
Table 1 shown that Kuwil reservoir is the best
choice for water source where is the water flow
system is the highest point to be used as a reference
in determining alternative water sources because it is
easier to operate and maintain.
SPAM Distribution System Planning consists of
raw water sources, Kuwil Reservoir. Production units
in the form of IPA and pumps. IPA will be planned
has capacity amount 50 L/s in 2025 and 3600 L/s in
2036 Two intake pump and one distribution needed.
Reservoir unit consist container reservoirs, Bengkol
reservoirs and Paniki Atas reservoirs with capacity
will be reaching 3000 m
3
.
The unit of pipeline consists transmission pipe
amount 6000 m and distribution pipe amount 5775 m.
3.2 Identification and Analysis of
Social Feasibility Factors
The population of Mapanget sub district amount
53,716 people. The growth rate of the Mapanget sub
district population from 2011 to 2016 can be seen in
Table 2. According to Table 2, the growth percentage
