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.
