Abstract

Springs as water sources are relatively inexpensive but highly susceptible to contamination since they are fed by shallow groundwater. Proper spring development helps protect the water from contamination. This study presents an analysis and design of spring development including the type of broncaptering/collecting wall, the dimension for the spring box and the conduction line. In addition, a guideline on “Springwater Construction” published by the Ministry of Public Works has been used in this design. A concentrated spring in Wates, Magelang, Central Java is used as a case study. The design calls for the collection of water from a spring using sets of broncaptering and a spring box, then piping it by gravity a distance of 5.1 kilometers to Van Lith Senior High School. Analysis was done using a manual calculation, which is subsequently compared to the result of HYDROFLO 3 software. Results show that the spring with a flow rate of 0.12 litre/s (manual) and 0.17 litre/s (software) will be collected into a 5 m 3 volume of spring box. The spring box with a +543 m water surface elevation is being supplied to Van Lith +384 m ground elevation using a uniform PVC pipelines with a ¾ inch of diameter.

Summary

Introduction

Capturing water from springs is a simple yet inexpensive process that has been used since ancient times. Inhabitants of rural mountain villages or underprivileged areas are primarily concerned about the development of springs because of the possibility to obtain pure water from neary sources with easy access at no cost. To clarify the ownership of the chosen spring, some negotiations about an ownership change have been done between a villager and Van Lith Senior High School. Prior to the use of spring water, the school had got the majority of their water from shallow wells, especially for domestic purposes. For other uses, such as to operate a swimming pool, the water was collected from drainage canals. Because of continuous contamination that leads to water quality deterioration, an access to cleaner water sources from the springs was needed
