Harvesting Techniques

Jakarta sebagai kota metropolitan memiliki masalah yang kompleks yang berhubungan dengan masalah krisis sumber daya air. Teknik pemanenan air hujan telah menjadi bagian penting dalam agenda pengelolaan sumber daya air dalam rangka untuk mengatasi ketimpangan air pada kurangnya hujan dan kekeringan (kekurangan air), pasokan air bersih masyarakat dunia, serta penanggulangan banjir dan kekeringan. Tulisan ini mencoba untuk menganalisis induksi deskriptif terkait dengan tema teknik pemanenan air hujan, dimulai dengan deskripsi dari pandangan terbuka dan data yang dikumpulkan dari literatur yang berkaitan dengan tema dan isu-isu sumber daya air di wilayah Jakarta, kemudian dilakukan analisis lebih lanjut dan kesimpulan yang diambil adalah terkait dengan aspek konservasi air dan pengelolaan sumber daya air krisis di DKI Jakarta.Jakarta as a metropolitan city has many complex issues related to the problem of waterresources crisis. Rain water harvesting techniques has become an important part in the global environmental agenda water resources management in order to overcome inequality of water in the rainy and dry (lack of water), lack of clean water supply community world, as well as flood prevention and drought. This paper tries to analyze the descriptive induction related to the theme of rain water harvesting techniques, starting with a description of the open view and the data was collected from literatures relating to the themes and issues of water resources in Jakarta area , then conducted further analysis and conclusions drawn are associated with the aspect of water conservation and water resources crisis management in DKI Jakarta.

Peak Summer

Groundwater occurring in the shallow aquifers is highly saline and is not suitable for drinking. Fresh potable ground water is occurring at great depth (245–325 m bgl). Occurrence of fresh ground water at deeper aquifers restricts large scale groundwater development, because it is beyond the economic capacity of common people. Source of drinking water is mainly Government owned hand pump fitted tube wells. Approximately per 70 households only one such tube well has been allocated. Many of these tube wells are yielding very less quantity of water during peak summer. Hence, the island is suffering from potable water scarcity especially during summer for around 4-5 months. Water supply is available in very few villages. Almost all the households are having one or two ponds. Most of the ponds are dried up during summer. Therefore, people in the island are facing water shortage round the year. The island receives very good precipitation (1900 mm) during monsoon. Major quantum of rainfall is lost as surface run-off to the sea or rivers. If this rain water run-off can be arrested and stored, island may be developed in many ways. There is a vast scope of Rain Water Harvesting (RWH) in Sagar Island. Water conservation can help to minimize the huge monsoon run-off. Roof top rain water harvesting can solve the drinking and domestic needs of the people of Sagar Island. In this context, harvesting and conservation of roof top rainwater during monsoon in storage tanks and ponds were explored, so that the same can be utilized in the lean periods. Present study has aimed to understand total amount of water may likely to be available from the concrete roofs of different existing buildings like public offices, schools, guest houses and individual houses as well as household ponds. At present, total water requirement of Sagar island in peak summer (4-5 months) for drinking and domestic uses is around 1589947.50 cu. m. Total amount of rain water be conserved through small household ponds (12418) and concrete roof tops (3194) is 3692853 cu. m. of which ponds contribute 3588976 cu. m. water and concrete roof tops used to contribute 10,38,77 cu. m. water. Thus, this conserved rain water could able to benefit in catering 492380 people (i.e., more than double of present population) of Sagar Island for five months in peak summer for drinking and domestic uses.

According to the latest government reports, India is facing evident shortfall of water in various parts of the country, and Himalayan states are likely to suffer the impacts of climate change related to water more than non-Himalayan states. Water resources are expected to affect Gross Domestic Product (GDP) of the country, and future projections are far more upsetting. In this light, sustainable and adaptive strategies such as integrated water resources management, nature-based solutions have been promoted globally for sustainable and integrated urban water management. The paper inquires into functions of respective institutions and their possibilities to adopt possible nature-based solutions such as rain water harvesting in response to water insecurity and adaptation in times of climate change. Taking case of Haldwani city, the paper assesses water demand and supply gaps, the existing water institutions, their scope of work and water management mechanism. Further, the scope of adoption of possible nature-based solution is explored by the purview of their work in water management. This was derived through an in-depth literature review, stakeholder consultations as key informant interviews, and participatory mapping. Haldwani has experienced severe water scarcity due to depletion of groundwater, decline in the discharge rate of river Gaula, and drying of springs in and around the city. Various agencies manage the existing water resources in isolation and mismanagement of water is one of the prominent problems in the city. The paper delves into the nuances of various strategic interventions, and the respective institutional capability to undertake the same. While most of the strategies prevalent at international level are yet to be adopted in context of Himalayan cities, a key finding is that rain water harvesting system can be easily taken up as a nature based solution by each of the institutions since it also falls in their scope of work as well as to meet the city’s present and future water challenges.
