Sewage company proposes new modular system<\/p>\n
Urip Hudiono, Jakarta<\/p>\n
This is the second in a series of three articles on the
\nenvironmental problems caused by untreated sewage in the capital,
\nparticularly the waterway and marine pollution it causes.<\/p>\n
Acknowledging Jakarta's urgent need for a better sewage system,
\nyet also realizing the difficulties in implementing a centralized
\nsystem, city-owned sewage company PD PAL Jaya is proposing that
\nJakarta adopt a modular sewage system instead.<\/p>\n
It is also proposing an upgrade for septic tanks in areas
\nwhere installing sewage pipes would not be possible.<\/p>\n
PAL Jaya director Pudjo Prihadi Santoso said a modular system
\nwould collect waste water from densely populated areas into
\nlarge, industrial treatment plants similar to the one in
\nSetiabudi, South Jakarta.<\/p>\n
\"Preliminary financial studies of the system have also found
\nit to be more feasible,\" he told The Jakarta Post recently.<\/p>\n
Under the proposed modular system, Jakarta will be divided
\ninto 38 modular areas, which would each be served by a local
\nsewage pipeline network and a small-scale treatment plant.<\/p>\n
He added that a comprehensive map would be drawn up next year
\nwith the City Development Planning Board.<\/p>\n
PAL Jaya data shows that a plant with a processing capacity of
\n3 liters of raw sewage per second could cost up to Rp 1 billion
\n(US$106,382).<\/p>\n
In regards the upgrading of septic tanks -- mostly used in
\nresidential areas -- Pudjo explained that it was important to
\nprevent further contamination of the city's groundwater and
\nwaterways in areas unreachable by sewage pipes.<\/p>\n
\"Most septic tanks can only treat human waste, while waste
\nwater from bathing and washing are simply flushed into the city's
\ndrainage system,\" he said. \"A modified septic tank would be able
\nto treat all kinds of sewage properly.\"<\/p>\n
PAL Jaya has been mulling a possible cooperation with
\nMalaysian company Pembinaan Jayabumi to supply the modified
\nseptic tanks, which come with scum filters and a medium to
\ncultivate waste-decomposing bacteria.<\/p>\n
Pudjo explained that residents could purchase the Rp 4 million
\n(US$425) septic tank through monthly installments of Rp 60,000
\nover 10 years.<\/p>\n
\"If the city administration decides to subsidize the program,
\nthe installments could even be reduced to Rp 33,000,\" he said.<\/p>\n
Pudjo suggested that all sewage matters be handled by PAL Jaya
\nin the future and monitored by the Jakarta Environmental
\nManagement Agency. Currently, the City Sanitation Agency provides
\nsewage trucks and treatment plants to serve those areas where PAL
\nJaya's pipeline networks are unavailable.<\/p>\n
However, PAL Jaya plans to expand its existing network to
\ncover additional areas where possible.<\/p>\n
Six service expansion areas have initially been determined by
\nPAL Jaya that would serve a total of 19,740 hectares. PAL Jaya's
\nSetiabudi plant currently serves only 560 hectares, or 0.85
\npercent of Jakarta.<\/p>\n
\"All in all, what we need are better regulations and
\ncoordination between city agencies to support the proposed sewage
\nsystem,\" Pudjo remarked.<\/p>\n
Present regulations on waste management includes Gubernatorial
\nDecree No. 45\/1992 that obligates all building owners to use PAL
\nJaya services in areas where its sewage pipes are available, and
\nGubernatorial Decree No. 2379\/2003, which specifies PAL Jaya's
\nservice charges.<\/p>\n
