Abstract:
Banjarbaru is one of the cities in South Borneo, which has developed very
rapidly in line with the growth of population and the physical building. This has
implications for the decreasing availability of water catchment areas. Therefore it
is necessary to built recharge wells to avoid a puddle of water on the surface. This
study aimed to quantify the discharge of rain and water for ablution, plan
dimensions and the number of recharge wells and budget plans for a large mosque
in Banjarbaru.
The infiltration wells design using Sunjoto formula. To determine the
coefficient of permeability of the soil, tested in the field by using a double ring
infiltrometer and testing in the laboratory by using Constant Head Test. This Tests
on three major mosques in Banjarbaru , the first is Al-Munawaroh Mosque, Jami
Hidayatul Muhajirin Mosque, and Al-Baythar Mosque.
The result is Al-Munawaroh Mosque designed infiltration wells depth of 5
m at a cost of one unit of infiltration wells Rp. 4,842,900.00, whereas for
Hidayatul Muhajirin Mosque Al-Baythar Mosque designed depth of 3 m at a cost
of one unit of infiltration wells Rp. 3,406,700.00.
