SISTEM BEKALAN AIR
DRAF KUALA LUMPUR 2020:PELAN BANDARAYA
Hala Tuju Strategik 10.6 – Memperkenalkan Kaedah Pengumpulan Air Hujan,
Kitar Semula dan Penjimatan Air
OBJEKTIFuntuk mengurangkan beban kepada sistem bekalan air dan sumber air.
• Selaras dengan pertambahan penduduk bandar raya yang dijangka meningkat kepada 2.2 juta pada tahun 2020,• penambahan kepada infrastruktur air amat diperlukan,supaya selari dengan perkembangan bandar raya Kuala Lumpur. •Tambahan pula penyediaan bekalan air yang bersih, berkualiti dan mencukupi merupakan keperluan utama penduduk yang perlu dipenuhi. •Sekiranya Kuala Lumpur tidak mengurangkan penggunaan air atau menemui sumber alternatif air, Kuala Lumpur dijangka akan mengalami kekurangan bekalan air pada masa hadapan.• Masalah ini akan menjadi lebih kritikal dengan jangkaan perubahan iklim pada masa hadapan.• Cuaca yang lebih panas akan meningkat permintaan air dan di tambah pula dengan perubahan cuaca yang akan menyukarkan pengekalan air pada masa hadapan.
INISIATIF KE ARAH MENCAPAI PENGURANGAN PERMINTAAN TERHADAP BEKALAN AIR BERSIH1. Menggalakkan pengumpulan air hujan dan penjimatan air untuk semua pembangunan jangka pendek sehingga tahun 2010. DBKL akan memberi insentif untuk pemaju yang menggunakan kaedah pengumpulan air hujan, kitar semula air dan penjimatan air.2. Menyediakan garis panduan yang memastikan kaedah pengumpulan air hujan dan penjimatan air dilaksanakan dalam semua pembangunan menjelang tahun 2020.

SISTEM BEKALAN AIR
SISTEM BEKALAN AIRSECARA LANGSUNg• Air dibekalkan terus dari paip induk.• Tidak mempunyai tangki simpanan.• Tangki simpanan diperlukan untuk silinder air panas sahaja.• Tidak sesuai utk bangunan tinggi.
SISTEM BEKALAN AIRSECARA TIDAK LANGSUNG• Air untuk lekapan sanitari & silinder air panas dibekalkan dari tangki simpanan, kecuali air dibahagian dapur.
The items identified in the illustration above of a direct water supply are: 1. Water company stopcock (pili penutup/kepunyaan PBT) - this is used to cut off all the
water to the property and is the point at which the responsibility for the water pipe changes; up to, and including, this stopcock the water supply company is the responsible for it; from this point to the house, the house owner is responsible even if the stopcock is not on their land (it's often in the pavement). Make sure that you know the location of this stopcock and, periodically, make sure that it's working - if you have a disaster with water in the property, you may need to turn the water off at this stopcock quickly.
2. Householders stopcock (pili penutup/kepunyaan pemilik rumah) - normally just one stopcock within the property will cut off all the water into it and the householder is responsible for it. This stopcock is normally located where the rising mains enters the house, often under the kitchen sink.
3 Draincock (paip buang) - this allows all the pipework within the house to be drained down at the lowest point.
Stop and drain cock with lever handle. Stop and drain cock with T handle.
4. Stopcock (Pili penutup) - this stopcock can be used to isolate the rising main from the cost water taps and WC cistern etc to allow maintenance in those areas without having to shut off all the water in the property.
5. Gate valve (Injap Get/Pintu) which can isolate the cold water feed to the multi point water heater.
6. Gate valve (Injap Get/Pintu) which can isolate the hot water from the multi point water heater to the taps etc. NOTE: Valves 5 and 6 allow for the water heater to be isolated for maintenance, repair or replacement.
7. Multi water heater - specifically designed to work at mains water pressure. 8. Inline valves to isolate water feeds to washing machine or dishwasher etc. 9. WC overflow pipe (Paip limpah) - this takes any overflow from the WC cistern out of
harms way and deposits it outside of the building. It needs to be positioned so that any water flow is immediately noticed as it would indicate a problem.
The items identified in the illustration above (NOTE that the central heating has been omitted for clarity) of an indirect water supply are:
1. Water company stopcock - this can cut off all the water to the premises and is the point where the responsibility for the water pipe changes; up to, and including, this stopcock is the responsibility of the water supply company (even if the stopcock is on your land); from here to the house, is the house owners responsibility. Make sure you know where this stopcock is located and, periodically, check that it's working - if you have a disaster in the house, you may want to turn the water off at this stopcock quickly.
2. Householders stopcock - this normally can cut off all the water within the house but the householder is responsible for it. It's usually located where the rising mains enters the house, often under the kitchen sink.
3. Draincock - this allows the rising main within the house to be drained down at the lowest point.
4. Stopcock - this stopcock can be used to isolate the rising main from the storage tank to allow maintenance without having to cut off all the water from the property.
5. Storage tank (tangki simpanan) with a ballcock float valve to control the water stored. The tank will typically hold from 230 to 360 litres (50 to 80 gallons) of water at the highest part of the building - the higher it is, the better the gravity feed pressure at the taps etc. From 1991, the tank should be fitted with a close fitting lid; the expansion pipe from the hot water tank should pass through a grommet in the lid to keep out contaminations.
6. Gate valve which can isolate the cold water feed to the hot water tank. 7. Gate valve which can isolate the cold water to the WC and taps etc. 8. Hot water cylinder.
9. Gate valve which can isolate the hot water to the taps. NOTE: Without the valves 6, 7 and 9, any maintenance on the taps or hot water cylinder etc would require the storage tanks to be drained down - by using the appropriate valve to isolate the part being worked on, the amount of water wasted is minimised.
10. Storage tank overflow pipe (paip limpah) - this takes any overflow of water from the storage tank out of harms way and deposits it outside of the building. It needs to be positioned so that any water flow is immediately noticed as it would indicate a problem. Since 1991, the entry to the overflow inside the tank should include a filter to prevent even a small insect from entering the tank.
11. WC overflow pipe - this takes any overflow from the WC cistern out of harms way and deposits it outside of the building. It needs to be positioned so that any water flow is immediately noticed as it would indicate a problem.
12. Inline valves to isolate water feeds to washing machine or dishwasher etc.
Stopcock or gate valve ? A stopcock works like a tap in that when it is closed, a washer is pushed over an opening to
stop the water flow whereas when a gate valve is operated a 'shutter' is wound across the opening. With a stopcock, some water pressure is usually required to lift the washer clear of its seat when it is opened to allow the water to flow; with a gate valve no pressure is required.
This basically is why stopcocks are used on the raising main (where the water pressure can be substantial) and gate valves are used on the water feeds from the gravity fed water storage tank (where the water pressure is a lot less and could be insufficient to lift the washer in a stopcock).
