Planning for the Development of a Clean Water Distribution System at PDAM Bersujud Tanah Bumbu at BNA Batulicin Unit

Abstract

In 2021 PDAM Bersujud Tanah Bumbu in the Batulicin BNA unit recorded a water
treatment discharge of 270 L/d, while the maximum daily demand discharge is 206 L/d, meaning
that there is still 54 L/d of water that should be used for the development of distribution networks,
and also in that year the coverage of clean water distribution services in the Batulcin District was
relatively small, namely 39%, this was because many people in the Batulicin sub-district used
ground water or drilled wells. continuous use of groundwater is not recommended, according to
Law no. 7 of 2004 article 34 concerning Groundwater states that groundwater is one of the water
resources whose existence is limited and its damage results in extensive impacts and its recovery
is difficult. So that at BNA Batulicin it is necessary to carry out a plan for the development of a
clean water distribution system. Planning is carried out for 9 years in accordance with Village
SDG's with a target of maximum service coverage or 100% until 2030. Planning is divided into 2
stages, namely in 2021 to 2026, and in 2026 to 2030. Calculation of water needs is calculated
from population projections by arithmetic and geometric methods. From the results of calculating
the water needs of BNA Batulicin in 2030 with a total population of 139,709 people, the average
water requirement is 328 L/d, the peak hour requirement is 492 L/d, and the maximum daily
requirement is 361 L/d.. Hydraulic simulation in the end of the pipeline network planning is
carried out with the EPANET 2.0 application, with the result that it meets the water flow technique,
namely the pressure parameter of 96% node is worth 10 – 30 mka and 4% is worth 30 – 50 mka,
while the pressure loss parameter is 40% is < 0.01 m/km, 31% is worth 0.01 – 1 m/km, 15% is
worth 1 – 4 m/km and 13% is worth 4 – 10 m/kmKeywords : PDAM, EPANET 2.0, Distribution
