Domestic rainwater harvesting has been revived in Sri Lanka since 1995 with the Community Water Supply and Sanitation Project. Since then, through the efforts of the Lanka Rainwater Harvesting Forum (LRWHF, an NGO set up to pro-mote rainwater harvesting for domestic need), the technology and the concept has been spread to other parts of the country. At present there are over 31,000 domestic rainwater systems in the country. Rainwater harvesting has been successfully legalized in Sri Lanka.  Key words: Rainwater harvesting; Water quality; Sri Lanka; Technology; PolicyDOI: 10.3126/hn.v6i0.4189  Hydro Nepal Vol 6, January 2010 Page : 27-30 Uploaded Date: 24 January, 2011

An evaluation of the water quality at the hatchery of Tanjung Riau was conducted to understand the water quality status at the several place of the hatchery unit such as brood stock tanks, larva rearing tank, water storage tank, fi ngerling tank as well as the source of the water supply. The water quality status of Tanjung Riau generally is in a good condition to support the hatchery activities, but for turbidity and salinity were in the exceed and below the normal status and its infl uence on the spawning activity. To overcome the problem on the spawning of the brood stock, the improving of water supply with higher salinity and low turbidity should be set up to ensure the succeeded of the spawning.Key words : Water quality, grouper brood stock, hatchery,Tanjung Riau Batam

Water scarcity is still a major problem in many rural communities in Nigeria. In this study, a rain water harvesting system was designed for Ogbekpen, a rural community in Edo state, Nigeria. A conceptual model for rainwater harvesting was developed using the storm water management model (SWMM), Arcmap 10.1 software and daily rainfall data (2000-2016) obtained from the Nigerian Meteorological Agency (NIMET). Runoff, rainfall intensity and change in elevation of three designated catchment zones were taken into consideration. The results revealed that the total amount of rainwater that could be harvested annually (water supply) was 14,314,351.70 L (14,314 m3) from an overall effective rooftop area of 6025.9 m2. This was three times the annual water demand (4,317,965.60 L (4318 m3)), thus demonstrating the capability of the system to meet annual water demand. The required tank capacities for zones 1, 2 and 3 were 870,412.76 L (870 m3), 955,319.4 5L (955 m3) and 788,629.88 L (789 m3) respectively. Comparative physicochemical and microbial analysis of water from rooftops in the three zones and an existing storage well showed that the latter did not comply with drinking water quality guidelines, thus highlighting the importance of a proper conveyance and storage system to improve water quality and availability in the area.

In the effort to carry out the principal functions and duties for the population in Papua, Papua provincial government set up several enterprises (BUMD) purposed to provide services to the public. BUMD is also expected to give contribution on regional income. The objectives of this research are: (1) Determining the health level of Local Government Owned Enterprises in Water Supply Company in Jayapura and Nabire from the financial aspect, (2) the health level of Local Government Owned Enterprises in Water Supply Company in Jayapura from the operational aspect, (3) the health level of Local Government Owned Enterprises in Water Supply Company in Jayapura and Nabire from the administration aspect. The method used in this research is survey research method toward BUMD by distributing questionnaires in several enterprises. The analytical tool used is the analysis on the health level of Water Supply Company on the financial, operational and administration aspects. Jayapura Water Supply Company health level in terms of financial aspects, operations and administration in 2011 to 2013 showed a reduction, but it was still sufficient indication. The total value of these three aspects has decreased in the last two years, 60.49 in 2011, decrease to 59.22 in 2012 and 54.59 by the end of 2013. However, this reduction was still at fairly healthcategory. Nabire Water Supply Company health level based on the financial aspect shows that from 2010 to 2013, the financial performance of Nabire Water Supply Company was experiencing unhealthy condition. Service aspect of the rate of complaints solving in 2010 to 2013 was always above 100%, it means that Nabire Water Supply Company have solved the problem of water services and other complaints that come from customers or not customer. The next indicator is water quality was 0% from 2010 to 2013. It means that they have not been able to serve the customers with the drinking water quality as provided in Ministry of Health Regulationnumber 492/MENKES/PER/IV/ 2010.

Water Supply And Sanitation

Water supply is a mandatory service for the majority from respective legal public water utilities, and its sustainability reflects implementations of best management strategies at a local level. The objectives of this study were (i) to assess current approaches used in water quality and quantity management and (ii) propose a sustainable domestic water management strategy. This was achieved through secondary water data trends, on-site water quality assessments, visits of water supply and sanitation authorities, and assessment of their performances. It was observed that water supplied in rural-based authorities was quite different from that supplied in an urban setting as far as quality and quantity are concerned; urban-based supplies are more affordable to users than rural ones. A new strategy on water management is presented for sustainable water supply; it is based on controlling groundwater abstractions and preference of surface water in public water supplies. Rural water supply management must learn several practices realized in urban supplies for the betterment of services for the majority of the users.

Domestic Water Supply

Rainwater harvesting in Palestine is a principal water resource that had been adopted since ancient times. However, the system had not been subjected to a thorough assessment. This paper aims at assessing the feasibility of rainwater harvesting for domestic water supply in Palestinian rural areas with special emphasis on socio-cultural and financial aspects as well as harvested water quality. Different methods were used to collect necessary data from a case study village, including literature review, observations, questionnaires and water quality measurement of freshly fallen and harvested rainwater samples. Moreover, domestic water demand and water supply from such a system were compared, and economic feasibility of applying this system was checked. The results revealed that harvested rainwater is a viable resource that can contribute considerably to minimizing water shortage.
