Catchment wells already in use<\/p>\n
JAKARTA (JP): At least 1,000 houses in Jakarta have already
\nbeen furnished with catchment wells under the guidance of the
\nCity Environmental Office, an official said.<\/p>\n
\"Most of the 1,000 houses with the catchment wells are in
\nhousing complexes,\" Aboejoewono Aboeprajitno, the head of the
\nenvironment office, said over the weekend.<\/p>\n
\"The catchment wells help maintain underground water levels.
\nThey are also effective in preventing floods,\" he added.<\/p>\n
The city administration is trying to control artesian well
\nuse, fearing that excessive use will speed up the intrusion of
\nseawater into the capital's ground water.<\/p>\n
Aboejoewono said underground water usage must be limited.
\nStricter permit procedures are needed to avoid further
\ndegradation of the capital's land and water systems.<\/p>\n
To accomplish this, the city raised household, commercial,
\nsocial and industrial artesian well fees between 150 and 250
\npercent last month. The state-owned water company, PAM Jaya, is
\nexpected to be able to provide well-water to the public.<\/p>\n
\"The rapid growth in construction and the population has
\nseverely damaged a number of water catchment areas,\" Aboejoewono
\nsaid.<\/p>\n
\"We have to be very careful with underground water because its
\nexistence depends on us. Trees are badly needed to help hold
\nrainwater in the water catchment areas,\" he vouched.<\/p>\n
Governor Surjadi Soedirdja said recently that the city's
\nunderground water potential is approximately 77 million cubic
\nmeters per year, enough to support the rise in water demand for
\nthe next ten years.<\/p>\n
Of the 77 million cubic meters, 40 million cubic meters is
\nfrom rain seeping into the ground, the other 37 million cubic
\nmeters is from the hilly Puncak area south of the city, he said.<\/p>\n
Surjadi said that based on geological data, rainwater levels
\nin the city reach about 300 million cubic meters annually, of
\nwhich 260 million cubic meters seep into the upper level of the
\nearth. The other 40 million cubic meters sink to a greater depth.<\/p>\n
It is estimated that the sustainable utilization limit of
\nexisting water sources is 42 million cubic meters a year.<\/p>\n
Data at the City Mining office indicates that there are 2,959
\nartesian wells in the city. They consumed over 2.8 million cubic
\nmeters of water in March. (31)<\/p>",
