Kemarin hari Minggu sedang jalan dengan keluarga ke TSM. Sewaktu pulang ngantri di sisi timur gedung, saya mencatat beberapa hal:

1) Mengamati hujan deras kemarin di TSM,talang air berdiameter >10″ mengucur air deras. Drainase luber (bahkan air muncrat setinggi setidaknya 30 cm dari celah-celah tutup drainase. Selain itu saya juga mengamati ada rig drilling sedang berjalan, ternyata memang sedang berjalan pemboran sumur imbuhan.
2) Tandanya air hujan berlebih, kualitas baik, lantas buat apa sumur air tanah terus dipompa? (setidaknya apakah bisa pompa hanya dinyalakan pada saat-saat tertentu saja). Saatnya menggunakan air hujan (lihat fenomena di no 1).
3) tampung air hujan, olah (sedikit), pakai. Utk yg sdh masuk drainase, injeksikan. Perlu instalasi injektor. Memang perlu investasi yang tidak sedikit. Tapi akan lebih hemat in long run.
4) Tapi suplai air aman, keran mengucur lancar, pengunjung pun tenang tdk perlu antri panjang jd tersenyum senang *halah* 🙂

 

 

 

About the author

My current focus is how to provide the hydrostratigraphy of volcanic aquifers in Bandung area. The research is based on environmental isotope measurement in groundwater and morphometry. My work consists of hydrochemical measurements. I am using multivariate statistical methods to provides more quantitative foundation for the analysis and more insight into the groundwater behavior, especially its interaction with surface water. I use open source apps like R and Python to do the job. In my spare time, I also have a side project to promote open science in Indonesia's research workflow. One of my current focus is promoting INARxiv, as the first preprint server of Indonesia (osf.io/preprints/inarxiv) and serving as ORCID and OSF (osf.io) ambassador. Research interest: Hydrochemistry, multivariate analysis, and R programming. Blog: dasaptaerwin.net, derwinirawan.wordpress.com. (https://orcid.org/0000-0002-1526-0863)
