PDAM Tirta Kerta Raharja Kabupaten
In 1923, the government of Netherlands Indies builds a new water supply system, capacity 6 Litres/second, in Kota Tangerang. The system was then managed by a body called "Water Leiding Bedrijf".
In 1943, when the Kabupaten Tangerang is formed, the water supply system is transferred to Bupati Tangerang, and the Water Leiding Bedrijf under the Kabupaten Tangerang’s Public Works Local Office.
In 1945, after the proclamation of the independence of the Republic Indonesia, the name" Water Leiding Bedrijf" is changed into "Perusahaan Air Minum Kabupaten Tangerang".
30 years later, the management of clean water supply becomes under the responsibility and authority of Perusahaan Daerah Air Minum Kabupaten Daerah Tingkat II Tangerang ("PDAM"), as per Kabupaten Daaerah Tingkat II Tangerang’s Local Regulation No. 10/HUK/1976 dated 13 April 1976. This was legalized by the Governor of West Java Province under the Decree No. 347/HK.011/SK/1976 dated 1st August 1976.
In 1999, the Decree No. 001.690/SK.108-HUK/1999 dated 27 May 1999 issued by the Bupati of Tangerang legalizes the name and logo of PDAM. Perusahaan Daerah Air Minum Kabupaten Daerah Tingkat II Tangerang becomes Perusahaan Daerah Air Minum Tirta Kerta Raharja Kabupaten Tangerang.
