South Solok Regency with a population of more than 163,000 people, 62.3% without access to clean water services through the Domestic Water Company (PDAM). The number of PDAM customers has been changed in Solok Selatan Regency in the last five years. Since the water capacity is very limited which means it difficult to increase the number of customers, so it is predicted to be unable to meet the increasing need for clean water. Based on the study of the potential for raw water availability in the South Solok Regency, Sungai Kapur has the potential as a source of raw water. To complete the potential study, it is necessary to know the quantity of raw water by examining hydrological parameters to optimize the planning of water resources potential. The quantity of raw water is assessed by the dependable flow to determine the low flow characteristic. Based on calculations, obtained a reliable discharge of 90% in monthly that can be used as raw water. The raw water source used has a discharge of ± 138.6 l / sec. However, the availability is uneven throughout the month, so a reservoir is needed to guarantee the availability of raw water for residents. In addition, raw water quality is assessed in terms of physical, chemical, and biological aspects. The results of the raw water quality test in the Sungai Kapur are eligible for raw water based on Government Regulations No. 82, 2001

Air merupakan kebutuhan penting bagi hajat hidup warga di Kabupaten Gunung Kidul, Daerah Istimewa Yogyakarta. Temuireng merupakan salah satu desa di kecamatan Panggang, Kabupaten Gunung kidul, yang kebutuhan airnya masih jauh dari cukup. Di desa ini terdapat 269 kepala keluarga dengan rata-rata 4 jiwa di setiap kepala keluarga, sehingga terdapat kurang lebih 1076 jiwa yang kebutuhan airnya masih belum terpenuhi. Air untuk suplai ke desa ini terkendala oleh kemampuan pemompaan dan kualitas air baku. Kualitas air baku dimusim  curah hujan tinggi yang berasal dari Baron maupun gua Ngobaran masih mengandung bakteri E-Coli 9000 per 100 ml sedang total bakteri Coliform 28000 per 100 ml. Dari analisa air dimusim curah hujan sedang total coliform 4000 per 100 ml, dan analisa air dimusim curah hujan rendah (kemarau) total coliform berkisar 400 per 100 ml. Dari persyaratan maksimum 50 per 100 ml. Material terjerap dalam media karst saling berkaitan, antara bahan organik (parameter coliform) dan anorganik (parameter TDS). Dengan proses pengolahan secara laboratorium yang melibatkan proses flokulasi, sedimentasi, untuk dosis tawas, PAC dan biji Kelor sebesar 0,5 – 1 ppm mampu menurunkan TDS dari kisaran 262-288 ppm menjadi dibawah 200 ppm, dan jika dilanjutkan dengan filtrasi dengan media filter zeolit mampu menurunkan TDS hingga dibawah 180 ppm dalam waktu pengendapan 30 menit. Dan untuk dosis kelor jika dilanjutkan dengan perlakuan filter karbon mampu menurunkan TDS hingga dibawah 160 ppm dalam waktu filtrasi 30-60 menit. Sedang untuk proses olahan dengan destilasi percik tenaga surya, dimungkinkan terjadi penurunan TDS maupun coliform namun diperlukan intensitas sinar matahari yang cukup tinggi untuk proses penguapan.ABSTRACT: Water is an important resource for the people in Gunung Kidul Regency, Special Region of Yogyakarta, Indonesia. Water scarcity is one of big issue in Temuireng, one of panggang’s district in the Gunung Kidul regency. There is 269 family living in this villge and every family consist of four person so there are approximately 1076 person who need the clean water. The clean water supply for this village constrained by pump power and raw water quality. Raw water quality in rainy season (high rainfall intensity) contains of E-Coli 9000 per 100 ml and total Coliform bacteri 28000 per 100 ml. Raw water quality in medium rainfall intensity season contains of total Coliform  4000 per 100 ml and raw water quality in summer season (low rainfall intensity) contains of total Coliform  400 per 100 ml, from maximum regulation 50 per 100 ml. Material absorbed in karst include organic (coliform parameter) and anorganic (TDS parameter), which related in each other, can contaminate the water. Flocculation and sedimentation using 0.5-1 ppm doses of alum, PAC and kelor are performed to purify the water. The coagulant can decrease TDS parameter from 262-288 ppm to under 200 ppm, and if this process continued with filtration (filter zeolit), it can decrease TDS parameter to under 180 ppm in 30 minute. If the process continued by filtration process (carbon filter) using kelor, it can decrease TDS parameter to under 160ppm in 30-60 minute. Using spark destilation solar energy process can decrease TDS parameter and coliform bacteria, but this process need high sunlight intensity for evaporation.

Raw Water Quality

An automatic coagulant dosage control technology for water purification plants was developed to deal with rapid changes of raw water quality parameters. Control logic was developed to decide coagulant dosage based on aluminum concentration in rapid mixing tank water based on results of semi-pilot scale experiments. This logic enabled quick feedback on the excess or lack of coagulant. It was found that the aluminum residual rate, which was proposed as an indicator of coagulation reactions, could be given as a function of coagulant dosage and turbidity. The effectiveness of the control logic was verified in semi-pilot scale experiments. Settled water turbidity was within ±0.5 NTU of target value even when raw water turbidity increased rapidly up to 100 NTU.

Raw Water Quality

An integrated approach for the identification and assessment of the most critical chemical contaminant(s) at a drinking water intake has been developed. It involves the determination of a threshold or critical raw water concentration (CRWC) for target contaminants using the observed overall removal efficiency of a specific water treatment plant (WTP) and regulated drinking water concentrations for the target contaminants. The exceedance probability relative to the CRWC based on historical raw water quality monitoring data is then calculated. Finally, the integration of the raw water quality data and the overall efficiency of a particular WTP sequence allows for identification of the most critical contaminant(s) as well as an advance indication of which contaminants are most likely to challenge a plant. The proactive nature of this approach gives a utility the impetus and time to assess current treatment processes and potential alternatives. In addition, it was found that three- or four-parameter theoretical distributions are more appropriate than two-parameter probability distributions for the fitting of raw water quality data. This study reveals that the reliance on raw and/or treated water contaminant concentrations in isolation or on theoretical removals through treatment processes can, in some circumstances, be misguided.
