The Difference

ABSTRACT This paper reports the application of information acquired by aerial survey to characterize water supply reservoirs in the Pajeú River Basin (Pernambuco State/Brazil). The survey was carried out with digital cameras of high spatial resolution and laser relief profiling (LiDAR technology). Two areas were selected to apply the remote sensing products. Small reservoirs in the Quixaba Creek Basin were identified based on their topographic characteristics. Given that the small reservoirs are “depressions” in the terrain, they can be “filled”, resulting in a new Digital Terrain Model (DTM). The difference between the filled DTM and the original DTM makes it possible to identify the reservoirs. A summary of the results is: 61 reservoirs were correctly detected; 18 reservoirs were not detected; 13 reservoirs were detected erroneously. In another application, the storage capacity of the reservoirs belonging to the hydrosystems of Pajeú River Basin was estimated. The storage in these reservoirs and maximum surface area were estimated using DTM and geoprocessing tools. From the total of 31 reservoirs evaluated, eight were completely empty at the time of the LiDAR data collection. The official registers reported 83.83 million m3 for the storage capacity of these eight reservoirs, whereas our applications estimated the value at 70.23 million m3. This difference is explained by the loss of volume in the reservoirs due to the process of sediment transport.

Hydrological Functioning

Watering ponds are an important source of drinking water supply for livestock in semi-arid rangelands. Understanding the hydrological functioning of this kind of infrastructures is crucial for efficient water management in areas where water resources are often scarce. In this line, we have analyzed temporal patterns of water availability in a set of watering ponds located in Iberian rangelands and their relationship with temporal rainfall variability. In addition, the effectiveness of the ponds for conserving stored water during dry periods and some influencing factors (pond size and catchment area) have also been assessed. The results showed a high correlation between water availability and precedent rainfall, confirming, on the one hand, the capacity of storage of these infrastructures and, on the other hand, the importance of temporal rainfall patterns in their hydrological behavior. Our findings point to a minimum pond area of 2000 m2 and a catchment area/storage capacity ratio around 100 m−1 in order for watering ponds can face the dry summer period with certain guarantees, at least in regular hydrological years. Nonetheless, the vulnerability shown by the majority of the watering ponds in times of drought limits their usefulness as unique sources of water supply in many farms.

Quality Status

Urbanization has caused limitations on water resources, while climate change has reduced amounts of surface water in some parts of the world. Kikuyu, a suburban area in Kiambu county, Kenya, is facing this challenge. The major challenge in the study is scarcity of potable water, resulting in inadequate water supply to Kikuyu residents. Currently, only 63.6% of the population is being supplied with water by Kikuyu Water Company, the company mandated to supply water to the area. Water demand was 2972 m3/day in 2015 and was projected to be 3834 m3/day by 2025. This has put pressure on the already exploited clean water resources, making it necessary to seek additional sources of domestic water. Storage capacity and water quality of surface water bodies, especially small reservoirs whose water can be used to ease the demand, need to be assessed for supplemental water supply. This study aimed at assessing the suitability of the abandoned quarry reservoir as a source of potable urban water by determining its storage capacity characteristics and water quality status. Volume characteristics were determined using bathymetry survey in January 2019. Water samples were collected in January and August 2019 and analyzed for chemical, physical, and bacteriological quality, as per the American Public Health Association (APHA) standard methods for water and wastewater. Parameters were evaluated based on World Health Organization (WHO) and Kenya Bureau of Standards (KEBS) guidelines for drinking water, and rated based on the drinking water quality index (WQI). The reservoir’s maximum storage capacity was found to be 128,385 m3, the surface area was 17,699 m2, and the maximum depth was 15.11 m. Nineteen of the twenty-five investigated parameters were within the acceptable standards. However, the concentrations of manganese (Mn), cadmium (Cd), iron (Fe), turbidity, total coliforms, and Escherichia coli (E. coli) were above the acceptable limits. Manganese and iron levels increased with depth. The overall WQI of the reservoir was 82.51 and 85.85 in January and August, respectively. Therefore, based on WQI rating, the water scored a good quality rating and could be used for domestic supply upon treatment. The original achievement of this study is establishment of the volume of the water in the quarry as an additional source of water to the nearby community, along with water quality status.

local wisdom philosophy of the Sumatera traditional house. The house is a combination between modern and traditional house of Sumatera which is a stilt house. The basement of the house is designed as rainwater storage in order to guarantee the availability of household water supply. On the other hand, the upper part of the house is designed as a dwelling. Simulation is undertaken in order to investigate the water volume behavior in the storage due to the variation of rainfall and water uses in the house. The simulation is applied in a house with a roof area of 54 m2, 4 residents, and 24 m3 of storage capacity. Daily rainfall data are obtained from the rainfall station in Bandar Lampung, Indonesia. The result of the simulation indicates that rainwater facility in the house is relatively effective to store rain water and to provide household water supply. For wet year periods, the system is able to supply about 80% to 90% of the total needs. Oppositely, in the dry seasons, the system can support the household water demand up to 60% of total needs.

La baja disponibilidad de agua potable de buena calidad puede ser complementada con agua proveniente de la lluvia, si esta última es recolectada en cantidad suficiente para cubrir la demanda, aprovechándose esta combinación para resolver el problema de abastecimiento, todo esto sujeto a restricciones de inversión. El presente trabajo tiene por objetivo presentar un análisis de los sistemas de captación de agua de lluvia existentes en la zona limítrofe entre los estados mexicanos de Quintana Roo y Campeche para estimar los montos de inversión máxima que justifiquen un proyecto de mejora en la disponibilidad de agua de lluvia. En esta investigación se identificó el nivel de aprovechamiento y los requerimientos de los sistemas de captación de agua pluvial en techos (SCAPT) y se determinó el monto de inversión máxima para solucionar esta situación problemática. Los resultados muestran que los SCAPT no se aprovechan debido a limitaciones o subutilización en la superficie de captación y/o capacidad de almacenamiento, por lo que se recurre al suministro de agua en pipas. Se concluye que se puede sustituir el acarreo en pipas por agua de lluvia con un adecuado dimensionamiento de la superficie y el volumen de captación, asegurando el consumo de agua mínimo recomendado, con una inversión menor de la que se requeriría para la implementación de un sistema de abastecimiento de agua convencional.   Low availability of good quality drinking water can be complemented with rainwater, if the latter is collected in sufficient quantity to cover the demand, taking advantage of this combination to solve the supply problem, all of this subject to investment restrictions. The present work aims to present an analysis of the existing rainwater harvesting (RWH) systems in the border area between the Mexican states of Quintana Roo and Campeche to estimate the maximum investment amount that justifies a project to improve rainwater availability. In this research, the use level and the requirements of rooftop rainwater harvesting (RTRWH) systems were identified and the maximum investment amount needed to solve this problematic situation was determined. Results show that RTRWH systems are not used due to insufficient or underutilized catchment area and / or storage capacity, so water is supplied in tankers. It is concluded that transport in tankers can be replaced by RTRWH with an adequate dimensioning of surface and catchment volume, ensuring the minimum recommended water supply, with a lower investment than that required for the implementation of a conventional water supply system.

This paper presents the study of water supply dams in Malaysia using the Storage Yield Reliability (SYR) model. The model is a linearized regressed equation with five independent variables comprising of hydrological and physical properties of the reservoir system, namely dam inflows and its statistical moment properties, reservoir storage capacity, and designated return periods or probability of non-exceedance of low flow. A total of twenty eight water supply reservoir schemes were selected for comparison in this study. Seventeen and eleven reservoirs respectively operated under direct supply (DS) and regulating reservoir (RR) modes. The estimated SYR yields were compared to the known water treatment plant (WTP) capacities of these reservoir schemes. Out of five variables, catchment area (indirectly proportionate to dam inflows) and storage capacity are positively correlated to the estimated SYR yields. The SYR model adopted in this study could provide quick yield assessment for all the twenty eight DS and RR reservoir schemes in Malaysia. In summary, the multivariate regression model SYR approach can be used as the first screening process of DS and RR operation mode reservoir yield estimation in Malaysia.

Domestic Water Supply

A safe rural domestic water supply project has been initiated based on different consumption uses. Long-term computation method and the water balance principle are used to analyze the yearly water demand. Water supply and demand balance is achieved through regulated planning of the rainwater collection surface area and water storage capacity. The best combination of collection area and storage capacity is then determined for various rainfall zones in order to satisfy safe domestic water needs. Ultimately, an optimum matching model is developed to utilize rainwater harvesting for providing safe domestic water in rural areas.
