Developing sustainable approaches to drinking water in rural areas has become an essential issue in many countries worldwide, especially where water supplies are limited or costly. As a result, many countries are investing in new technologies, ranging from low-cost, locally produced technologies to multi-use systems.
Multi-use water systems
Using a Multiple-Use Water System (MUS) is an approach to water service delivery that benefits communities by fostering greater resilience and a more thriving local economy. It is more sustainable and cost-effective than single-use systems, often leaving water in short supply. MUS provides life-changing access to drinking water to rural communities in 22 countries.
The benefits of MUS include:
- Improved health and sanitation enhanced.
- Enhancing livelihood security.
- Providing opportunities for girls and women in rural and peri-urban communities across the Global South.
MUS helps communities improve water allocation decisions by giving villagers a more significant say in the design and operation of water systems.
Managing water resources via a multiple-use water system is a relatively recent concept. It delivers water to homes in small communities while considering the various uses of water in system design.
The MUS strategy has aided in giving rural communities in more than 22 nations access to water that can change their lives. It combines local water management capability development with integrated local water arrangements.
It also provides greater water security to all households. Women and girls are often responsible for obtaining household water, so planning for the system can help them to focus better on other pursuits.
Multiple-Use Water Systems can be incorporated into the original design of a system or be used as a stand-alone solution. The key is understanding the community’s needs and developing an appropriate solution.
A Multiple-Use Water System can help communities address their water access challenges by developing villagers’ water management capacity and monitoring implementation. It also opens up new investment opportunities in water and sanitation services.
Multiple-use water systems have been an innovative approach to water service delivery in the Global South. They have also been shown to save water, which can be a lifesaver in rural areas where water is in short supply.
MUS is also gender-friendly, making it more likely to benefit entire communities than single-use systems. This means that women and girls can focus on homestead gardens and cooking instead of fetching water for drinking and cleaning.
There are many different sources of water in the world. While many water users depend on groundwater, cities use surface water from rivers and reservoirs.
Global water supplies are under stress due to the world’s population’s rapid rise and environmental constraints brought on by climate change. Desalination is one approach to solving this issue. The reverse osmosis technology is used in desalination to remove salt from saltwater. Brackish water can also be treated with this technology.
While ocean desalination is not the solution to all water problems, it can be a good start. Desalination plants use reverse-osmosis technology to force water through a semi-permeable membrane. This process uses less energy than direct seawater use and is a low-energy alternative to distillation.
Another option for water supply is recycling wastewater. This option is regulated and less expensive than desalination. Recycling wastewater is already a viable option in many arid regions.
Another technology that may be an option is enhanced stormwater capture. This method can increase storage capacity up to fourfold in areas with infrequent rain. It may also be a successful method for purifying nearby groundwater resources.
Despite its environmental benefits, many questions still surround desalination’s cost and efficiency. Although desalination costs are falling, it still lags behind other options for water supply.
This is mainly due to the high energy costs associated with desalination. The cost of energy may also increase as energy prices rise.
Significant technological advances still need to be made to make desalination more sustainable. For example, separating salt from water is getting better and more efficient. This means the energy required to remove salt from water is less than a few years ago.
In addition to technology, other factors must be considered to make desalination a more sustainable solution. This includes developing high-tech methods for treating wastewater and improving water quality. New technologies allied with public-private partnerships can help chart a sustainable future.
While desalination may not solve all water problems, it can be crucial in addressing the water crisis. Its ability to provide a freshwater source at a low cost is essential.
Low-cost and locally-produced technologies
Providing clean, safe drinking water to rural areas is a significant challenge in developing countries. Almost half the world’s population lives in remote, rural areas and lacks access to clean water. In these areas, the water may contain harmful pathogens that can harm human health. Providing affordable water treatment is vital in reducing morbidity and the risk of health complications.
There are several conventional solutions to provide clean drinking water in developing countries. However, these solutions are often unaffordable and challenging to finance. Typically, these solutions rely on the last-mile water consumers’ reliability and the water provider’s ability to collect payments.
Combining innovative technologies and financing methods accelerates the provision of last-mile water infrastructure.
Several technologies have been developed to provide clean drinking water to rural areas. These technologies include point-of-use (POU) systems, which are user-friendly and low maintenance. They are also grid-independent, which allows off-grid operation.
Maji Safi International LLC has developed low-maintenance, slow sand water filter technology for the past few years. Through the development of this technology, Maji Safi hopes to provide clean drinking water to developing countries.
The organization recently received $10,000 from the Purdue Burton D. Morgan Center for Entrepreneurship and additional support from AMPATH.
Other technologies that could benefit rural communities include the rope pump, which is easy to use and maintain. The rope pump is a hand-powered device that moves water up and down through a tube on a rope. The rope pump is also available in bicycle versions.
Water reuse systems can also provide a solution to freshwater shortage problems. A study on small-scale water reuse facilities reports costs and operational data for various package systems and unit treatment processes. In addition, the study identifies innovative water reuse technologies.
A new business model can also address the needs of rural areas in an integrated approach. This can help to reconcile the conflict between the demand for domestic water and the need for agricultural water.
It can also enable the efficient use of resources and help resolve the multiple-use services issue. This could be in the form of a public-private partnership (PPP) model.
Community water organizations
Providing sustainable drinking water in rural areas is a complicated and challenging task. This is due to various factors, including climatic conditions, water supply infrastructure, sanitation infrastructure, water demand, and population density.
The most remote populations are often the most vulnerable. Therefore, creating an integrated development strategy that addresses these factors is essential. Incorporating sanitation and water security into the plan is also important.
In rural areas, water is often delivered at the community level. These services provide a lower quality of service and do not have the scale or functionality that urban systems provide. In addition, rural water systems are often not regulated. However, several nonprofit organizations provide clean water solutions to communities worldwide.
These nonprofits focus on several factors to ensure that these solutions are sustainable.
Safe Water Network works to build water systems that are locally owned. It provides technical services and education to communities. The organization works with local government, businesses, and schools to provide clean water to rural communities.
Its goal is to reach 50 million people by 2026. The organization helps to develop community leaders and train local businesses to install water systems.
Water for Good is a nonprofit organization that works with communities in Central Africa and other countries. It helps to improve agriculture, create sustainable clean water access, and establish sanitation best practices.
The organization provides equipment and spare parts, as well as government oversight. It also provides education and training to community members to operate and maintain stations.
A comprehensive water management plan should be based on local data and unique intervening factors.
It should also take into account all life-cycle costs. The organization has developed a Sustainability Analysis Tool to characterize the needs of rural communities and identify weaknesses in support mechanisms.
It was tested on 61 rural water systems in the Dominican Republic.
A new institutional framework can help to address these issues. It could be a new business model, such as a PPP or centralized subsidy model.
