The Impact

Good management of water resources is a requirement for an area that has a high population development. Sentul City, which is an independent city in Bogor Regency which has a high population, is in an area that lacks water, because of this Sentul City requires infrastructure and policies that are able to ensure the availability of water for its residents. One of the paradigms of water management in urban areas is a water sensitive city. One of the steps in this paradigm is wastewater management and rainwater harvesting. The dynamic system modelling method is used to predict the impact of implementing several policies that will be taken to manage water resources. The objectives of this study are to build dynamic models to predict water supply and demand and to analyze policies for wastewater management and rainwater harvesting. Sentul City water demand is estimated will reach 122 105 000 m3 and a water crisis will occur in 2027. The wastewater recycle policy can inhibit the water crisis until 2030 and the negative water balance will last until 2040. Combining wastewater recycle and rainwater harvesting can increase water availability by 240% and prevent a water crisis.

Unfavorable Condition

Many islands in Korea have problems related to water source security and supply. In particular, the water supply condition is worse in small islands which are remote from the mainland. A couple of alternatives are developed and suggested to supply water to islands including water hauling, groundwater extraction, and desalination. However, these alternatives require much energy, cost, and concern in installation and operation. Rainwater harvesting is a sustainable option that supplies water with low energy and cost. However, lack of practical or comprehensive studies on rainwater harvesting systems in these regions hinders the promotion of the system. Therefore, this research examines defects of current RWH systems on an existing island, Guja-do, and provides technical suggestions in quantitative and qualitative aspects. A simple system design modification and expansion of system capacity using empty space such as a wharf structure can satisfy both the qualitative and the quantitative water demand of the island. Since rainwater harvesting is estimated to be a feasible water supply option under the Korean climate, which is an unfavorable condition for rainwater harvesting, implies a high potential applicability of rainwater harvesting technology to other regions over the world suffering from water shortage.

Sustainable Water Supply

City governments, the world over, are grappling with the problem of sustaining water supply to their rapidly growing population. The need to meet up with this exigency has been emphasized in Sustainable Development Goal (SDG) 6 (Ensure availability and sustainable management of water and sanitation for all) and SDG 11 (Make cities and human settlements inclusive, safe, resilient, and sustainable). While a series of demand and supply-side approaches to water management have been employed, the extent to which water management practices could guarantee (un)sustainability still require clarity, especially in the context of cities in Sub-Saharan Africa (SSA). Taking the case of the Bamenda Metropolis of Cameroon, we contribute to address this lacunae, by identifying household level water management practices in Bamenda, and discussing the implications it has for sustainable water supply (availability, affordability). To obtain relevant data for this study, a random sample of 120 households, within 8 neighborhoods of Bamenda, was conducted. Furthermore, we employed descriptive and inferential statistical methods to test the relationship between household socio-economic characteristics and water management (consumption, rationing, preservation). The results  reveal the following: In terms of regularity, approximately 63% of the households have irregular water supply, and consume less than 50 litres of water per day. The key water source is pipe borne water (65%), supplied by CAMWATER and Community Water Systems. One of the main water management practice at household level is rainwater harvesting (41.7%), while sustainability is compromised by the weak management systems from supply side, and limited knowledge and resources at the demand side (household level). There is a need for policy (re)orientation to regulate household water distribution, consumption and affordability. Further studies are required to ground this assertion.

The method of water harvesting is very crucial to the collection of the volume of water required for sustainable water supply. Most physical water scarcity remote rural areas worldwide are characterized by a reasonable amount of rainfall. These areas lack the suitable Surface Rainwater Harvesting System (SRHS) to collect the required water volume. To address this problem a remote sensing data based Surface Rainwater Harvesting Approach (SRHA) was proposed. The proposed approach was tested on existing surface rainwater harvesting systems (SRHS) in residential and agricultural areas inside the study area. The study area is bounded by latitudes 11°-12° N and longitudes 33°-34° E, with an approximate area of 11,000 km2. The SRTM90 DEM data of the study area was processed using QGIS application program hydrological modules. The hydrological model of the area was created, the catchment areas were derived and draining capacities for the specific test sites were calculated. The results revealed that the remote sensing data based approach is capable of locating sites with draining capacities 82 and 8 times those of the traditional systems in the residential and agricultural areas respectively. These results demonstrated that the proposed approach can facilitate locating optimum surface rainwater harvesting sites that would provide sustainable water supply and mitigate physical water scarcity problem in remote rural areas.
