<div> <p>Onsite rainwater harvesting is an inexpensive water source for indoor use; it is also a sustainable water management practice, since it may contribute to the reduction of runoff volume and peaks, and to the control of non-point source pollution. The aim of this paper is to provide a method for sizing rainwater harvesting tanks based on the local daily rainfall record, the served family size, the roof collection area, the roof type, the in-house water uses, and other factors. Various methods used worldwide are presented and compared. The comparative application of these methods is made using a daily rainfall record from a meteorological station near Kimmeria Village in Xanthi, Northeast Greece. Based on the proposed method here, the optimum tank size is computed by allowing excess water to overflow and setting to zero the use of the public water supply; the method may result in reduced tank sizes compared to other methods tested.</p> </div> <p>&nbsp;</p>

Willingness To Accept Compensation

Agricultural non-point source pollution (ANSP) has become one of the main sources of pollution in water source areas. An effective solution to this problem is the use of ecological compensation to encourage rural households to adopt agricultural pollution control measures. This study aims to answer two questions: How much compensation should be given to encourage rural households in water source areas to participate in ANSP control? What factors will influence their participation? In this study, paddy rice planting in water source area has been used as an example aiming to answer these questions. This study used the random parameter logit (RPL) model with survey data from 632 rural households in the Qinba water source area to empirically analyze rural households’ willingness to accept compensation for ANSP control and the influencing factors of this willingness. From this information, the compensation standards for ANSP control in a water source area were calculated. The results show that (1) compensation had a significant incentive effect on rural households’ willingness to control ANSP. The marginal compensation standard for reducing the use of fertilizer and pesticide was $3.40/ha and $2.00/ha, respectively. The compensation standard for not applying chemical fertilizer and pesticide at all was $540.23/ha. (2) There was heterogeneity in rural households’ preference for ANSP control compensation policies. Rural households characterized by younger residents, higher family income, higher perception of the ecological benefits, and higher perception of government policy were more willing to participate in the compensation policy. It is suggested that rural households showed a strong preference for ANSP control policies by considering both of their economic losses and ecological benefits. Our study contributes to the literature by enriching the evaluation method in providing references for the compensation of ANSP control policies

As the world population increases, the demand increases for good quality of drinking water. Surface and groundwater resources are being consumed faster than they can be recharged. Rainwater harvesting is an old practice that is being adopted by many nations as a viable decentralized water source. This project is to prepare a model for rainwater harvesting from rooftops and we are designing Rainwater harvesting system in a residential building to use the rooftop rainwater and recharge ground water from excess water & concrete roads of residential houses then making demo model to show different collaborative techniques.

Non Point Source Pollution

Nowadays, agricultural non-point source pollution has become the main pollution source of water environment, especially for drinking water. Water sources protection has become a major problem in national economy and people's livelihood. Rural contiguous improvement project, including rural drinking water source protection, rural domestic sewage treatment, rural living garbage and livestock industry pollution treatment, can not only improve rural living environment, but also effectively reduce the non-point source pollution source of the water sources. A case study in north China showed that, after rural contiguous improvement, the amount of pollution source reduced significantly, so as to protect and improve the environmental quality of water source reserve effectively.

The continuous destructions to water bodies while the demand for potable water increases; call for immediate move to seek and improve the adoption of alternative water sources to augment the existing sources. Though Ghana has a rain harvesting strategy, very little seems to be done to improve its implementation and to sensitize the public on its adoption. It is an established fact that adoption is premised on perception but very little has been done to uncover the perception of the general public on rain-harvesting and the portability of rain water as alternative water source. This study seeks to resurrect the need to look in the direction of rain harvesting. Mixed method strategy was adopted to address the stated objectives. The results indicate that greater number of the respondents did not consider untreated rainwater as good enough for drinking but fit for all other domestic uses. The respondents identified lack of appropriate and affordable rain-harvesting system, mode of storage, contaminations with microbes when stored for long and softness as the demoralizing factors that inhibit rainwater harvesting. In conclusion, the analyses showed that rainwater harvesting is on the lower side in the area of adoption among households and major consumers of water in Cape Coast. The results confirm the 2010 census that rain harvesting is not a major source of water to the people of Cape Coast metropolis. The study recommends that stakeholders such as the Ministry of Sanitation and Water Resources must embark on mass education on the need to adopt rainwater as complement to traditional source of water and also support experts to design comprehensive rain-harvesting technique which will improve collections, storage and distribution at an affordable rate for the general public and effectively publicise it for adopts and use.  Citation: Abena Yeboah Abraham1, Prince Adjei2 and Doris Ohene Ntim3.
