In Finland the question of appropriate wastewater treatment in rural areas has become very prominent during the last years. The new Environmental Protection Act stipulates that wastewaters must be treated to the extent that they cannot have a negative impact on nature. The Ministry of the Environment is currently preparing a decree specifying the requirements. The draft of the decree proposes that on-site treatment units should decrease the BOD load by 90, total phosphorus load by 85 and total nitrogen load by 40 per cent. To meet the new requirements, the old systems that include septic tanks only need more efficient wastewater treatment methods. Whatever technical solution is selected, the house owner must pay for it. At the moment, even the septic tanks are emptied and maintained irregularly. More sophisticated wastewater treatment methods definitely need more maintenance, which cannot be made the sole duty of the house owners. One potential organisational alternative for managing wastewater treatment in rural areas is the co-operative. Finland has one such pioneering co-operative formed for on-site sanitation. Varsinais-Suomi Water Services Co-operative provides the house owner with professional assistance in wastewater treatment at a reasonable cost. Suvisaari Water Services Co-operative is another new organisation selling sewerage services to its members. But its technology is different: this co-operative operates an LPS-sewerage system instead of on-site treatment.

The purpose of the study was to evaluate, in a local approach, the state of supply of rural areas in a rural district with household wastewater management systems, with the focus on home wastewater treatment plants. The study covered the rural areas of the district of Olsztyn. The data, which were acquired from the Bank of Local Data, were processed through basic mathematical transformations and statistical measures. The structure and intensity indices were calculated per 1,000 residents. Large differences were found in the access to linear infrastructure and to individual systems of wastewater discharge. The results showed a constant increase in the number of home wastewater treatment plants and septic tanks due to the constant influx of people to villages lying around the town of Olsztyn. In contrast to studies conducted on a regional scale, no decrease in the number of septic tanks was observed correlated with the growing number of home wastewater treatment plants. A possible reason can be the specific environmental conditions and protection of inland waters, which limit possible locations of home wastewater treatment plants.

In comparison to other European countries, Ireland has a very large rural population. As of 2006, 42% of Irish people lived in rural areas. In cities and towns, wastewater is generally treated by centralised treatment plants. However in rural areas, wastewater from domestic treatment is typically decentralised, i.e., wastewater is treated on-site. The most common method of on-site wastewater treatment is private septic tanks and associated percolation areas. In all, there are 400,000 septic tanks in use around the country. These septic tanks and percolation areas are in various states of maintenance. Often, septic tanks are leaking or incorrectly constructed. Percolation areas are frequently clogged and do not treat the wastewater adequately. Typical treatment efficiencies of this system are of the order of 40% removal of organic matter, and 15% removal of nitrogen and phosphorus. Faulty septic tanks and percolation areas are viewed as a major environmental concern by the ...

Water management and associated wastewater management is an inseparable element of life and development of modern societies. Collection and treatment of wastewater has a significant impact on the environment and economy, both at the local and global level. It is therefore necessary to proceed to activities that ensure proper wastewater management, especially in rural and low-density areas, where it is necessary to search for optimal solutions with regard to sewage systems, including wastewater treatment plants. One of the solution for wastewater treatment from houses without access to sewerage collection system is the construction of on-site wastewater treatment plants. Construction of on-site wastewater treatment plant poses a number of challenges for municipalities and potential investors and has been discussed by many. Aim of this paper is to draw the current status and perspectives of on-site wastewater treatment systems in Poland, with focus on selected case study from rural areas. The paper presents a way to solve the problem of wastewater management in the municipality of Pietrowice Wielkie using local biological wastewater treatment plants. The article presents technological, technical and economical aspects of the above-mentioned solutions and analysis of the advantages and disadvantages of the system proposed by the municipality.

Abstract The biogas project for domestic sewage treatment (BPDST) is considered a promising facility for wastewater management in rural areas of China. This paper explores previous experimental works, cost analysis, and BPDST structure and design based on Chinese literature. Opportunities for developing decentralized or neighborhood-based BPDSTs include fulfilling Millennium Development Goals (MDGs) and Sustainable Development Goals (SDGs), the water pollution situation and deficiency of wastewater treatment facilities, the advantages of BPDSTs compared with centralized sewage plant, government support and policy drive for rural wastewater treatment, and reuse demand for resources. Meanwhile, challenges faced are emphasized as follows: uncertain responsibility for BPDSTs under different governmental departments restricts BPDST development and should be specified; uncertain effluent quality due to low efficiency of nutrient removal requires aerobic post-treatment to some extent; rural environmental awareness is still low and should be heightened; more funds should be invested in R&D for improvement of technology innovation; more reuse and resource recovery elements should be considered during implementation; follow-up services are lacking and should be improved; and BPDST maintenance should be trained. This paper could provide valuable reference for other developing countries.

This study was carried out to quantitatively and qualitatively investigate sources of water pollution in Pojuca river basin, in order to define ameliorative interventions. The basin of Pojuca river is located in Recôncavo Norte region, immediately northwards from Salvador da Bahia, capital city of Bahia State (Brazil). River Pojuca is the main water body of the region and it represents a very important potential source of water to be used for drinking purposes, in order to face the rapidly growing population of Salvador da Bahia Metropolitan Area. According to previous studies, its quality did not meet the minimum standards set for surface water withdrawn for potabilization treatment in 2000. In the present study, the most polluting activities have been identified as urban sewage discharges. Wastewater management coverage rate ranged between 30 and 90% in a high number of municipalities in the basin. Wastewaters were commonly discharged on the soil or into it (by means of septic and rudimental tanks) and also urban sewage systems, where existing, often did not convey wastewaters to treatment plants. Polluting loads were estimated according to a methodology elaborated during the study. The estimation was based on the data collected by the authors through field visits and the ones available in the federal databases (updated to year 2007). It allowed to establish that diffuse loads were major than point loads: point discharges were quite rare, whereas pipelines discharging in water bodies and infrastructures such as septic or rudimental tanks were widespread. Treatment plants and septic tanks presented small removal efficiencies of nutrients. This justified also the high organic and microbiological concentrations registered in the river as well as the high content of nutrients. Water quality could be improved in order to meet standards for drinking purposes by building new wastewater treatment plants or upgrading the existing ones. In particular, in urban areas dynamic systems for wastewater collection and treatment plants should be built, whereas in rural areas scattered households should be provided with septic tanks.

Water and sewage management in Poland has systematically been transformed in terms of quality and quantity since the 1990s. Currently, the most important problem in this matter is posed by areas where buildings are spread out across rural areas. The present work aims to analyse the process of changes and the current state of water and sewage management in rural areas of Poland. The author intended to present the issues in their broader context, paying attention to local specificity as well as natural and economic conditions. The analysis led to the conclusion that there have been significant positive changes in water and sewage infrastructure in rural Poland. A several-fold increase in the length of sewage and water supply networks and number of sewage treatment plants was identified. There has been an increase in the use of water and treated sewage, while raw sewage has been minimised. Tap-water quality and wastewater treatment standards have improved. At the same time, areas requiring further improvement—primarily wastewater management—were indicated. It was identified that having only 42% of the rural population connected to a collective sewerage system is unsatisfactory. All the more so, in light of the fact that more than twice as many consumers are connected to the water supply network (85%). The major ecological threat that closed-system septic sewage tanks pose is highlighted. It is pointed out that they are mainly being replaced by household wastewater treatment systems with ineffective filtering drainage. Furthermore, recommendations were also made for the future development of selected aspects of water and sewage management, including the legal and the political.

At the present stage of development, the entire world industry has faced the problem of rational use of renewable natural resources, in particular the most efficient ways of wastewater treatment and the use of accumulated waste in the production process as a secondary raw material. In particular, the alcohol industry, as one of the components of food, medical, chemical and various industries,leads to the formation of huge amounts of waste, including wastewater. The food industry, like any other industry, has a negative impact on the environment. Water bodies are the most affected by the food industry. Almost the first place in terms of water consumption per unit of production is the production of alcohol. Consumption of large amounts of water leads to the formation of wastewater, which is highly polluted and adversely affects the environment. Due to the high chemical and biological consumption of oxygen, specific color and odor, suspended solids, low pH value, the purification of such waste in the filtration fields and discharge into water bodies is not possible. The purpose of our work is: 1) conducting the analysis of the alcohol industry potential in Ukraine in recent years, and methods of waste disposal as a potential source for the development of bioenergy. 2) environmental aspects of the alcohol industry modernization at present stage of development and implementation of modern wastewater treatment technologies.

This paper focuses on the legal and institutional framework of urban water services in Spain, emphasizing water sanitation by using proposals that would positively contribute to wastewater management in Brazil. The recent Brazilian Federal Law No. 14,026/20 aims to encourage investment in water sanitation, promoting public-private collaboration formulas so that service management is viable even in economically less-favored regions. In Spain, sanitation policies are aimed at fulfilling the set of obligations and objectives imposed by European Union Directives within the environmental policies of the Union. From an economic point of view, supply and sanitation water services are classified at European legal framework as “services of general economic interest” (SGEI), not subject to harmonized regulation and open to a natural monopoly provision regime, which they admit various types of management formulas, public and private, based on the ownership and public intervention of the service, both at national and European level. We believe that the Spanish experience in this field, beyond its singularities, can serve as a useful reference for Brazilian’s urban wastewater new regulation for several reasons: (1) Because of the decentralized political scheme that both countries share and the need to articulate an adequate system of competencies in consequence; (2) Because of the international experience that Spanish companies have at the sector’s technological forefront, they are very competitive; (3) Due to the adequate functioning of the Spanish legal and organizational framework since, despite its shortcomings, as we later will comment, it has managed to develop successful financing formulas and management models that, in general terms, have allowed to ensure with reasonable efficiency, continuity, stability and sustainability in the provision of urban water services.

Pollution from wastewater discharges requires the treatment of all wastewater to maintain water bodies in good condition, as well as the possibility of reusing this water. Thus, wastewater treatment is an activity that has developed significantly in the Region of Valencia and has significant costs, including energy, which represents the main economic cost and an important environmental cost. In this way, efficiency and adequate financing of this activity are essential to minimise our environmental impact. However, the main funding tool currently does not allow us to address this issue, so we have a wastewater treatment with a high environmental cost in the form of greenhouse gas emissions. This tool is part of the revenues of water services, so it is not entirely independent, but it also seeks to prevent households from paying too high a total price. This leads to a situation where changes are needed to improve the financing of the different water services, as the financial resources obtained are insufficient and do not allow the current environmental problems to be solved. The analysis shows the importance of an appropriate tariff structure, as well as the need to include aspects such as water pollution and energy costs in the wastewater treatment tariff.
