The City

The City and County of San Francisco (“City”) embarked upon a 30-year master planning process in part prompted by public concerns related to the neighbourhood impacts of the Southeast Water Pollution Control Plant (SEP). The Sewer System Master Plan, as it is called, developed a long term Integrated Urban Watershed Management Plan for the City's treatment plants and collection system. This paper focuses on the planning framework and public input to the process, particularly as it relates to proposed changes to the SEP. The resulting improvements address issues of replacing aging infrastructure, eliminating odor emissions, and visually screening the treatment plants that are situated within an urban setting. The recommended project addresses the needed repair of the existing infrastructure; and proposes that the City move towards an integrated urban watershed approach, initially through localized rainwater harvesting and opportunistic water reclamation.

Bacterial Growth Rates

The aim of this study was to investigate whether the bacterioplankton activity in the meso-eutrophic Conceição Lagoon would increase significantly under allochthonous inputs of inorganic nutrients and organic carbon. Abundance and biomass of bacterioplankton were evaluated under three treatments: light (14 h light/10 h dark), complete darkness (dark-control), and nutrient (C + N + P—dark, 100 : 10 : 1) enrichments during 72 h. Nutrient enrichments promoted a significant increase in abundance (maximum of 19.0 ×109 cells·L−1 in the first 32 hours) and biomass of the heterotrophic bacterioplankton, which induced the formation of large clusters. Bacterial biomass remained constant in the non-enriched incubations (dark-control and light). Bacterial growth rates were significantly higher after nutrient additions (1.35 d−1), followed by control (0.79 d−1), and light (0.63 d−1) treatments, which were statistically equal (p>0.05). Bacterial production rates were also significantly higher under nutrient additions (1.28 d−1), compared to the control and light (0.50 d−1 and 0.44 d−1, respectively), demonstrating that bacterial growth and production in this meso-eutrophic lagoon are under an immediate “bottom-up” regulation, followed by a potential top-down effect. These facts reinforce the urgency on improving the local wastewater management plan in order to prevent further expansion of anoxic waters.

Domestic water supply and wastewater management are essential indicators of urban quality of life globally, and yet remain major environmental issues in Nigeria. The rapid growth in population has resulted in a higher rate of wastewater generation in Nigerian cities. However, many city plans are unable to cope with these issues appropriately. As a result, the poor management of wastewater is an ever-present problem with its attendant risks to public health and environmental safety. Therefore, this study attempts to analyse the control of urban development and management of domestic wastewater in Suleja, Nigeria. The study critically examines the current urban planning systems and presents an overview of selected technologies adopted for the decentralised treatment and disposal of wastewater in emerging nations. To this end, a documented and dissertation based analysis technique was employed in this study. Firstly, the paper begins by providing a methodical framework for comparative examination of the centralised and decentralised systems. The legal setting and policy framework, present city plan, and wastewater management are also explained. The study finds that loose development control and organic growth of residential development have a strong influence on wastewater management in the community

The purpose of this research is to find out the influence of economic, social and availability of information variable on the healthy life behavior of the people in Suruh Sub-district, Semarang Regency. The primary data source is collected by distributing the questionnaires to and by interviewing the people of Suruh Sub-district, Semarang Regency as the research respondents with the research analytical instrument of Probit binary responses regression. The availability of domestic wastewater disposal facilities is the dependent variable, while the household expenditure (economic variable), healthy life motivation (social variable) and maintenance of domestic wastewater disposal system (healthy life behavior) are the independent variables. The results show that the healthy life motivation and maintenance of domestic wastewater disposal system variables have positive and significant influence on the availability of domestic wastewater disposal facilities with ? = 5% and the household expenditure variable has positive and significant influence with ? = 10%. In general, it shows that the economic variable and the household expenditure determine the availability of domestic wastewater disposal facilities in Suruh Sub-district, Semarang Regency as the higher the individuals income, the higher their allocation to the household expenditure, including to the domestic wastewater management.

The regulations said that all domestic wastewater first should be treated before being discharged into public drainages. Therefore, IMERI building, as a research and education building located in the Faculty of Medicine, Universitas Indonesia, applies a wastewater management system using activated sludge technology combined with microorganism biofilters. This system is expected to treat the waste generated inside the building. It reprocesses become recycled water and partially discharged into city drainages based on the quality standard and maintenance applied during the operation. By collecting and evaluating primary and secondary data from system planning and routine maintenance results, we assess all performance of the WWTP system. Moreover, this system runs well and has all indicators of effluent categorizes safe. However, routine maintenance and the treatment process with chlorination and tighter monitoring should be taken seriously to keep the whole system's performance.

The Impact

The degradation of water quality has become a major problem today. In Indonesia, the decline in water quality is caused by domestic wastewater which is a non-point source. In an effort to reduce the occurrence of environmental degradation due to domestic wastewater, it is necessary to give an idea and convince the public and the relevant parties of the importance of domestic wastewater management. Efforts are made by informing the pattern of distribution of domestic wastewater in a region and the impact of its distribution for its control and management. The research method uses a momentary sampling technique in accordance with SNI 6989.59:2008. The location of the water sampling is determined purposively. Sampling was conducted in two periods; the dry season in September and the rainy season in January. The observed parameters included BOD5 and E.coli. Determination of the distribution of domestic wastewater uses GIS. The distribution of domestic wastewater is determined based on pollution levels expressed as IP. The results show that pollution levels in Sawojajar and Sumbersari were lightly polluted with average IPs of 4.09 and 4.02 (dry season). While Kedungkandang is in the good category, IP = 0.32 (dry season).

Control Study

At Manisa Organized Industrial District (OID) chosen as pilot study area, a detailed wastewater profile and pollution control study has been realized. A pretreatment strategy was determined and a wastewater management plan was prepared. Existing central treatment plant was studied and cost items were determined. These evaluations were compared with the redesign options generated from our own wastewater management plan. Same treatment units and their combinations were successively designed for variable flow rates between 100-50,000 m3/d. Thus data for new OIDs of similar nature as Manisa, an optimized treatment scheme as well as its approximate cost varying with the wastewater inflow was generated. Proposals for preparing environmental criteria to be considered and applied in newly establishing or planned OIDs are summarized.
