Abstract Indonesian airport in general relies dominantly on the surface and underground water to fulfil its water demand. Although groundwater systems are generally more resilient to climate change than surface water sources, their overuse might damage those water systems. One alternative to overcome this problem is rainwater harvesting (RWH) which could be implemented to increase the availability of raw water supply. However, in Indonesia, the study of the potential of RWH at a regional scale is still limited, so it does not provide sufficient information for practical application. Therefore, as the objective, this research will utilize a simulation analysis method to calculate the volume of rainfall storage, water requirements and reliability levels at I Gusti Ngurah Rai Airport regarding variations of the catchment area. This scheme would be applied not only during the dry and rainy seasons but also during the El Nino event. Moreover, the rainfall return periods would be determined to define the potential size of a rainwater harvesting system yearly. As a result, RWH at I Gusti Ngurah Rai Airport has the potential to substitute the surface water (PDAM) and groundwater usage either fully or partially depends on the season and water catchment area.

The industrial sector is one of the important sector in supporting the development of a region. Utilization of land around the river that is used for industrial activities will affect the quality of river water. The river can be polluted by waste personinating from industries that operating around the river. The catchment area that used for industry, agriculture, urban development, and the use of land for making roads (gravel or footpaths) can affect the flow of surface water and sediments that it brings to the river. Waste generated from industrial activities can pollute rivers which are a source of water for daily needs and affect the development of biota in them. This can affect river water quality

Abstract The water catchment area of the Trotuş river lies on about 4340 square kilometers of which 66% are in the mountain area of the Central Group of the Eastern Carpathians (Moldo-Transilvans). In recent years the manifestation of natural hazards aggressiveness multiplied. In 2005 (12-13 July) and 2010 (26-27 June) Trotuş Valley was affected by strong floods that have produced great material damage. Hydro-technical works carried out after the 2005 summer hazard were swept away by the 2010 hazard, when were affected about 3,000 households in the upper course of the Trotus, most of the damage being recorded on the Agăş Creek Valley to the confluence with the Trotuş, the administrative territory of the commune Agăș, where about 2000 household suffered. The late melting snow on the Ciuc and Tarcău Mountains peaks mixed with summer rains determined total isolation of the Cotumba, Sulța, Goioasa and Coșnea hamlets. Provisory bridges realized on the main roads on the side valleys, where are many hamlets, renewed in 2009 summer, were quickly clogged and then swept away by the rough waters of the Trotus and its tributaries. In the upper basin of the Trotus. Over the past 20 years have been recorded up phenomena of paroxysm of the climatic and hydrologic hazards among which the creeks Grohotiş and Sulţa flooded the villages Goioasa and Sulţa. On the 12-13 July, 2005 the Creek Agăş flooded a part of the Agăş village, about 2 kilometers, in line, of households. Drăcoiu creek broke the wall of channeled flood reached exceptional values, the maximum flow at Vrânceni hydrometric station being of 2800 cubic meters/s (probability of overflow 0,5%) and the flood volume here was the biggest of all the existing measurements.

With the growth in water demand worldwide, cities are experiencing increasing difficulties to guarantee the public supply of drinking water. Therefore, the search for alternatives that replace the available sources needs to be disseminated. An alternative to reduce the demand for drinking water is to use the Rainwater harvesting system. This work analyzes the feasibility of implementing a system for capturing, storing, and distributing rainwater for non-drinking purposes in three standard projects of the National Fund for the Development of Education in three locations in the state of Pernambuco: Recife, Caruaru, and Petrolina. To achieve this objective, local rainfall data, the catchment area used and the demand for non-drinking water in the building were analyzed. Then, sizing calculations of the storage reservoir were performed by different methods. The time for return on investment was considered satisfactory for all types located in Recife and for the 1-room type in Caruaru and Petrolina, considering the benefit from the system in the long term. Therefore, the typologies of 6 and 12 rooms in Caruaru and Petrolina were excluded since they had a return time of more than 24 years. The advantages are not only financial, but also environmental, cultural, and educational.

Abstract Pramuka Island is a small island that is covered with dense settlements, inhabited by 1,715 people, and experiencing rapid population growth with increasing visits by tourists every year ]. As a result, there is a high demand for freshwater, leading to a large-scale exploitation of groundwater on the island. Yet, a research conducted by [1] had indicated that groundwater on Pramuka Island is below the minimum standards for drinking water. This report discusses the effectivity of a rainwater harvesting system as a solution to the freshwater carrying capacity of Pramuka Island. The discussion involves analysis of freshwater carrying capacity based on water balance calculations between freshwater supply with rainwater harvesting and potential freshwater demands for domestic usage, tourism, and other activities. The results revealed that the scenario of the whole island as a rainwater catchment area is enough to supply local freshwater demand for approximately 27 years.

The studies on management and use of water resources has been one focus of several research, they are looking for alternatives to the use of natural resources and sustainability. The study aimed to planning, execution and estimate the economic return of the use of rainwater for washing vehicles, agricultural machinery and implements. The study was conducted for the sector of mechanization of the Polytechnic School of the Federal University of Santa Maria, from March 2011 to February 2013. The roof of agricultural mechanization sector has a catchment area of 215.45 m2 . Five tanks of 7000 liters each were installed. The underground water consumption was reduced by 100%. It was used 458,120.25 liters of water from rainy and intended for the proposed activities. The reservoirs were the largest investment, accounting for 63%, followed by washing 27% and 10% of total costs. A total savings of R $ 2009.66 was obtained and monthly R $ 83.74 depending on the costs of water. The system of rainwater harvesting is an alternative to reduce the consumption of water from other sources.
