Q & A
What are the four key criteria for evaluating a water supply system mentioned in the script?
-The four key criteria for evaluating a water supply system are quantity, quality, continuity, and variety.
What is the difference between 'feasibility' and 'suitability' as described in the script?
-Feasibility refers to the suitability of utilization after meeting measurable standards, such as clear water being drinkable after disinfection. Suitability refers to the usability of water without measurable standards, like clear water being suitable for handwashing.
What are the six aspects that need to be considered when assessing the feasibility of a water supply system?
-The six aspects are technical, economic, financial, social, institutional, and environmental.
Why are the economic, institutional, and environmental aspects similar across different components of a water supply system?
-These aspects are similar across different components because they support general activities like economic development, institutional operations (such as standard procedures), and minimizing environmental impacts.
What distinguishes the technical aspect between distribution components and other components in the water supply system?
-The technical aspect differs significantly between the distribution component and other components due to the variation in design capacity. The design capacity of distribution systems is larger, which affects financial and social feasibility.
How does fluctuating water consumption influence the design of the distribution system?
-Fluctuating water consumption leads to variations in daily and hourly usage, which influences the need for a larger design capacity in the distribution system to handle peak usage times.
What are the key factors considered in the decision-making process for water supply system planning using the downstream approach?
-The key factors are technical, financial, and social aspects, as they directly impact the system's feasibility, especially regarding design capacity and user consumption patterns.
What is idle capacity in the context of water supply systems, and why is it important?
-Idle capacity refers to the unused capacity of the system, such as water treatment tanks or pipeline sizes that are built for long-term use but are not fully utilized in the short term. It is important because it affects the system's financial feasibility.
Why is there a difference in the design capacity between distribution and upstream components?
-There is a difference because the distribution system needs to accommodate peak consumption times, resulting in a higher design capacity compared to upstream components like water sources and reservoirs.
How can the planning process for water supply systems reduce idle capacity?
-The planning process can reduce idle capacity through careful design and phasing of component procurement to align with short-term and long-term system needs.
Outlines
🚰 Overview of Drinking Water Supply System Planning
The first paragraph explains the approach to water supply system planning, beginning with the distribution aspect. It highlights four key criteria for evaluating a system: quantity, quality, continuity, and diversity, aimed at long-term sustainability (e.g., 50 years). It contrasts 'feasibility' (determined by measured standards like disinfecting water) with 'suitability' (where no strict standards are needed, e.g., water is suitable for hand washing). The system is assessed across six aspects: technical, economic, financial, social, institutional, and environmental. It emphasizes that while economic, institutional, and environmental factors are consistent across components, technical considerations differ, especially between distribution and other system elements. These differences impact financial and social aspects, making them crucial for decision-making in the downstream approach to water supply system planning.
📈 Water Usage Fluctuations and Design Capacity Implications
The second paragraph discusses water consumption patterns, noting the fluctuating nature of usage throughout the day. It introduces key terms such as average daily flow (QRH), maximum daily flow (QHM), and peak hourly flow (QJM), explaining how these values are used to calculate factors like the maximum day factor (FHM) and maximum hour factor (FJM), both typically greater than 1 in Indonesia. It highlights the impact of these fluctuations on the design capacity of distribution systems, which must be larger than that of upstream components to accommodate peak usage. This leads to idle capacity in the system, especially in the early stages, and affects financial feasibility, as consumers may initially bear the costs of long-term investments. The paragraph also suggests that starting system planning from the distribution side leads to fewer iterations and more efficient outcomes.
🔧 Reducing Idle Capacity in Water Systems
The third paragraph briefly mentions future efforts to reduce idle capacity in water distribution systems, leaving this topic for a future discussion. It concludes the video with thanks and a farewell message.

Highlights
The topic discusses an approach to evaluating water supply systems based on four key criteria: quantity, quality, continuity, and diversity.
Long-term planning, up to 50 years, is a primary focus when assessing water supply systems.
The downstream approach emphasizes the suitability of water usage after meeting measurable criteria, such as clean water being drinkable after disinfection.
Suitability without measurable criteria is defined for tasks like washing hands, where clear water is considered acceptable.
The system's components are evaluated across technical, economic, financial, social, institutional, and environmental aspects.
The economic aspect is clear in its support of economic activities, and institutional aspects are critical for the standardized operation of system components.
There is a significant difference in technical aspects between distribution and other system components, especially regarding design capacity.
Technical, financial, and social factors are critical in decision-making for downstream water system planning or evaluation.
Water usage fluctuates, meaning the demand is not constant, and daily peak usage is a key factor to consider.
Maximum day factor and peak hour factor are important ratios that help in understanding water usage trends.
Design capacity for distribution components is larger than for other system components due to these fluctuations in water usage.
Idle capacity is a key concept, referring to the available water capacity that is not yet utilized.
Components like water processing tanks and pipeline diameters are often overdesigned for long-term usage, leading to idle capacity in the early years.
Consumers must bear the costs of long-term investments in distribution systems upfront, impacting financial viability.
An effective planning or evaluation method starts from the distribution side, reducing the need for iterative design adjustments and ensuring efficiency.

pendekatan perencanaan atau evaluasi
sistem penyediaan air minum dimulai dari
distribusi pendekatan helir itu berbasis
empat kriteria sistem yaitu kuantitas
kualitas kontinuitas dan
keragaman yang kesemuanya untuk tinjauan
jangka panjang sebutlah 50
tahun sebagai suplemen uraian ini anda
dapat mempelajari buku yang saya
sediakan berikut
ini pada kesempatan kali ini topik du
mendeskripsikan penguatan pendekatan
Hilir itu dengan basis kelaikan
sistem kelaikan adalah kesesuaian
pemanfaatan setelah memenuhi tetapan
terukur misalnya air jernih adalah la
minum setelah
disinfeksi atau pendidihan untuk
eliminasi
mikroba beda dengan kelayakan yang
menunjukkan ke sesuaian pemanfaatan
tanpa tetapan
terukur misalnya air jernih adalah layak
cuci tangan atau badan dan
sejenisnya kelaikan seluruh komponen
sistem ditinjau melalui en aspek yaitu
teknis ekonomi finansial sosial
institusional dan
lingkungan aspek ekonomi Kom sistem
jelas untuk mendukung aktivitas
ekonomi aspek
institusional juga jelas untuk tiap
komponen
misalnya prosedur operasi standar dalam
pelaksanaannya juga aspek lingkungan
berlaku untuk tiap Komponen yang dapat
meminimalkan dampak
negatifnya jadi tiga aspek ekonomi
institusional dan lingkungan tidak
signifikan berbeda untuk tiap komponen
sistem sementara itu aspek teknis adalah
berbeda signifikan antara komponen
distribusi dan komponen-komponen
lainnya perbedaan signifikan itu
terletak pada kapasitas
desain perbedaan kapasitas desain itu
membawa implikasi kepada aspek finansial
dan
sosial Oleh karena itu tiga aspek teknis
finansial dan sosial menjadi faktor
pengambilan
keputusan dari pendekatan Hilir dalam
perencanaan atau evaluasi sistem
penyediaan air
minum mulai dari
distribusi pemakaian air konsumen adalah
fluktuatif
fluktuasi pemakaian air itu merupakan
implikasi langsung dari kelaikan
sosial Tiap orang keluarga atau kegiatan
lain-lain mempunyai pola pemakaian air
tiap waktu adalah
berbeda sementara itu pengaliran air
dari sumber ke reservoar adalah konstan
tiap waktu
secara teknis misalnya di dalam
pengolahan air memerlukan kondisi aliran
konstan untuk proses yang efektif dan
[Musik]
efisien kita awali dengan pengamatan
air sepanjang
tahun tiap hari debit pemakaian air
berfluktuasi fluktuasi itu mempunyai
rerata yang dikenal sebagai debit rerata
harian
qrh pada hari tertentu ada pemakaian
tertinggi yang disebut sebagai debit
hari maksimum
qhm pada hari maksimum itu juga jadi
pemakaian
fluktuatif pada jam tertentu ada
pemakaian tertinggi yang dikenal sebagai
debit jam maksimum atau debit Puncak
qjm dengan pengamatan itu kita dapatkan
faktor hari maksimum
FHM sebagai rasio
qhmqrh yang lebih besar dari 1 tipikal
Indonesia lebih besar dari
1, juga kita peroleh faktor jam maksimum
fjm sebagai rasio
qjmqhm yang lebih besar dari 1 tipikal
Indonesia lebih besar dari
1,7 berdasarkan fluktuasi pemakaian air
itu yang menghasilkan qjm lebih besar
daripada
qhm Maka kapasitas desain distribusi
lebih besar dari kapasitas desain
komponen holu mulai sumber air sampai
dengan
reservoar perbedaan kapasitas desain itu
memberi implikasi kepada kelaikan teknis
kapasitas menganggur
idle capacity dan kelaikan finansial
kapasitas menganggur adalah kapasitas
air tersedia tetapi belum
termanfaatkan kapasitas menganggur juga
berlaku untuk media
air misalnya ukuran bak pengolah air
1000 m³ untuk jangka panjang tetapi
untuk 5 tahun pertama ukuran bak hanya
termanfaatkan mengolah air 100 m³
demikian pula untuk diameter perpipaan
yang dipasang 1000 mm untuk jangka
panjang namun sesungguhnya cukup 250 mm
untuk 5 tahun
pertama kapasitas menganggur itu adalah
kepastian dari suatu produk layanan
jangka
panjang sekalipunap komponen dapat
disediakan secara bertahapun
desain melekat di
dalamnya pentahapan pengadaan tidak
menghilangkan faktor kapasitas desain
distribusi yang lebih besar dari
komponen
lain tentu saja kelaikan teknis
kapasitas menganggur itu memberi dampak
kepada kelaikan
finansial konsumen harus membayar saat
awal biaya investasi jangka panjang
sistem
distribusi dengan kajian cermat dan
proper mulai dari sistem
distribusi maka perencanaan atau
evaluasi komponen hulu lebih mudah
mengikutinya boleh saja siapun memulai
perencanaan atau evaluasi dengan
pendekatan hulu mulai dari sumber menuju
distribusi namun pada posisi Sisi kajian
distribusi akan dihadapkan kepada
masalah-masalah tersebut di atas
fluktuasi pemakaian air kapasitas desain
dan terutama kapasitas
penganggur pada posisi itu saya yakin
perlu iterasi berulang untuk
menghasilkan desain Like
System itu sebabnya saya merasa nyaman
dalam hal ini tidak banyak iterasi bila
mengerjakan perencanaan atau evaluasi
sistem penyediaan air minum mulai dari
distribusi hasilnya efektif sehingga
kerja menjadi efisien
[Musik]
dengan urian di atas yang menarik adalah
upaya penurunan kapasitas
menganggur nantikan itu pada kesempatan
berikutnya terima kasih wasalamualaikum
