Raw domestic wastewater from an individual home was characterised and the water quality was followed after disposal to a partially sealed cesspit over the whole filling period of 4 months. The results revealed that raw wastewater was of medium strength according to the US EPA classification, and was more concentrated than Palestinian municipal sewage. Septage is the water accumulating in the pit, but above the accumulated bottom sludge. The septage was more concentrated than the raw sewage. The specific household water consumption, wastewater generated, septage collected by vacuum truck and septage water infiltration were respectively (59 L/c.d; 100%), (52 L/c.d; 87%), (11 L/c.d; 19%) and (40 L/c.d; 68%). The specific removal of pollutants in the cesspits were: BOD5 (78 g/c/d), COD (62 g/c/d), N total (52 g/c/d), PO4-P (66 g/c/d) and TSS (69 g/c/d). The specific pollution loads of emptied septage were BOD5 (5.6 g/c/d), COD (19.3 g/c/d), N total (4.8 g/c/d), PO4-P (0.17 g/c/d) and TSS (25.5 g/c/d). The concentrations of heavy metals (Cu, Pb, Mn, Fe and Zn) in septage water were not in compliance with heavy metals concentration limits of the Palestinian regulations for wadi disposal and effluent reuse in agriculture. As a consequence, septage disposal in wadis and agricultural fields is not safe. However, according to municipal regulations, the heavy metals concentrations allow septage to be disposed in the Al-Bireh wastewater treatment plant septage receiving unit, to be further treated in the aerobic system. Regarding nitrogen that is removed in the cesspit, the vast majority will most likely exfiltrate out of the cesspit into the surrounding soil, and might potentially reach the groundwater. Therefore, cesspits should be replaced by proper wastewater treatment systems.

Increasing concern about bathing water quality in Scotland has led to renewed interest in diffuse sources, as well as the already closely monitored municipal sewage effluents and combined sewer overflows (CSOs) that have been the subject of multi-million pound capital expenditure schemes for several years. Early investigations of diffuse sources focused on rural land uses. This paper is an initial effort to consider the possible significance of urban diffuse sources. A review of the potential for diffuse urban sources includes consideration of sewage pollution in surface water sewers, as well as non-human sources such as pigeon and other bird roosts, and faecal material from pets such as dogs and cats. Portobello beach in Edinburgh is the case study selected, because of earlier work done by Scottish Water and SEPA. The Figgate Burn crosses Edinburgh to discharge onto the beach at Portabello, and pollution sources in its catchment are described. Additional information is reported from Dunfermline, where the sewer network has provided examples of three ways in which sewage pollution can occur in urban streams, and also Scottish examples of measures to control some non-human sources (e.g. SUDS).

The main objective of this study is to carry out to design of a sewage treatment plant for a Nagore and Nagore district, because it has been one of the developing pilgrimage places. Due to steady increase of increasing population, there will be more generation of domestic and municipal sewage. Sewage produces obnoxious smell which causes disease to all creatures. To avoid this problem, proper treatments is necessary before disposal to land by not throwing sewage directly to natural resources and reuse the treated water that ultimately reduces the overall demand of fresh water. Its objective is to produce an environmental safe fluid waste and solid waste suitable for disposal or reuse. In one day the total sewage generated was estimated 5 MLD considering the projected population of Nagore town for the next 30 years? Consequently this paper focuses on the sewage generation in the Nagore area based on the population and sewage treatment plant is designed accordingly. It is proposed to design the various components of sewage treatment plant considering the various standards and permissible limits of treated sewage water. The various components of sewage treatment plant are screening, grit chamber, primary sedimentation tank, biological reactor, secondary clarifier, activated sludge tank and drying beds.

The Past

The Standards controlling sewage treatment are continuously in development. Thus, upgrading existing plants is a frequently encountered problem. In the past this meant structural changes, mostly in terms of enlargement of existing facilities or addition of new units. More recently the possibilities of improving plant performance through chemicals addition (inducing precipitation and coagulation) with or without intensified biological treatment have been explored. Chemicals addition has become necessary in many instances due to the tightening of standards for phosphorous concentrations in the plant effluent. The present discussion is based on a case study where possibilities and limits of chemical and/or biological upgrading have been investigated. The analysis showed that neither chemical stages nor secondary biological stages alone can guarantee the effluent standards formulated by the water authorities.
