Bengaluru's original sewerage system was built in 1922, a time when the city was much smaller than it is today; the original system served only the heart of the city. In 1950, with the city greatly expanding, a project was initiated to greatly expand the sewerage system. After the Bengaluru Water Supply and Sewerage Board (BWS&SB) was formed in the 1960s, programs were again implemented to expand the system to unsewered areas. Bengaluru‟s growth has been phenomenal. During the last two decades the city of Bengaluru has been experiencing unprecedented growth in the field of Industrial, Commercial and Institutional sectors. This phenomenal growth has resulted in unplanned urban activities surrounding Bengaluru and increase in population and construction activities. As per the census the population of Bengaluru city was 4.08 million in 1991, 5.8 million in 2001, 8.5 million in 2011 and increased to 11.5 million in 2016. This fast growth in population is posing tremendous pressure on infrastructure especially on water supply and underground drainage system. Bengaluru‟s rapid urbanization has also meant growing mountains of waste – solid and liquid. It is estimated that roughly 1,400 MLD of wastewater flows through its three valleys– the Vrishabhavathi , the Koramangala - Challaghatta, and the Hebbal. Sewerage flow in the city follows the regional topography and flow down along the three principal valleys and five minor valleys ensuring free flow of sewerage without any major pumping requirement. BWSSB is now proposed to construct 6 new treatment plants of total capacity of 520 MLD for treating the additional wastewater generated. The total cost of the scheme is Rs.1373.42 Crores. Tender was invited through Government Of Karnataka e-Procurement by the Chief Engineer (WWM), Bengaluru Water Supply and Sewerage Board, Kempegowda Road, Bengaluru-560 009, Karnataka, on behalf of the Chairman, BWSSB, Bengaluru, for the Construction and consultancy services for the Construction of 40 MLD Capacity Sewerage Treatment Plant at Doddabele, Bengaluru during the year 2016-17.

(2020-09-21T07:09:36Z) CHINMAY, M; MAHENDRAN, A M; MANOJ, C; MOHITH, C
In late decades, shear dividers and cylinder structures are the most proper basic structures, which have made the stature of solid structures be greatest. In this way, late RC tall structures would have more confounded auxiliary conduct than previously. Hence, considering the auxiliary frameworks and related conduct of these sorts of structures would be exceptionally intriguing. Here in this paper; we will consider the auxiliary parts of one of the tall RC structures, situated in the high seismic zone, with 10 stories. In this structure/Tower, shear divider framework with sporadic openings are used under both horizontal and gravity stacks, and may result some uncommon issues in the conduct of auxiliary components, for example, shear dividers, coupling bars and so forth. To have a seismic assessment of the Structure Tower, a great deal of non-straight examinations are to be performed to confirm its conduct with the most common rules like FEMA 356. In this paper; some particular parts of the tall structure/tower and the evaluation of its seismic burden bearing framework by considering some significant variables will be talked about. At long last, after a general investigation of pliability levels in shear dividers; we will finish up the optimality and thought of the tall structure/tower plan. At last, having some specialized data about the basic conduct of the case would be exceptionally interesting and helpful for fashioners.
Analysis and Design of Multistoried Building Subjected yo Dynamic Loading

Recommendations provided by seismic codes help the designer to improve the behaviour of structures so that they may withstand the earthquake effects without significant loss. Seismic codes are unique to a particular region or Country. They take into the account the local seismology, accepted level of seismic risk, properties of available materials, methods used in the field of earthquake engineering and property. Most of the recommendations of IS codes are based on observations during past earthquakes as well as experimental and analytical studies made by scientists, engineers and seismologists. In India, the 1st seismic code namely IS 1893 was published in 1962. Seismic analysis and design for this project will be in compliance with IS 456/IS 1893, The concept of earthquake resistant design is that the building should be designed to resist the forces which arises due to design basis earthquakes, with only minor damages and the forces, which arises due to maximum considered earthquakes with some accepted structural damages but no collapse. The design philosophy was established considering the following aspects: The structure should withstand the moderate earthquakes, which may be expected to occur during the service life of structure with damage within acceptable limits. Such earthquakes are characterized as design basis earthquakes. The structure should not collapse when subjected to severe ground motion that could possibly occur at the field. Such earthquake is characterized as maximum considered earthquakes. Buildings are designed as per Design based earthquake, but the actual forces acting on the structure is more than the design earthquake. So, in higher seismic zones Ductility based design approach is preferred as ductility of the structure narrows the gap. The primary objective in designing an earthquake resistant structure is to ensure that the building has enough ductility to withstand the earthquake load.

Analysis, Modeling and design of Automatic Uplift Bridge During flood
(2025-04-28) Kiran N N; Gnana Teja A; Sunil Zulpi
The automatic height-adjusting bridge represents a significant advancement in engineering design. Commonly referred to as movable bridges or drawbridges, these structures employ sophisticated mechanisms to modulate their elevation. Typically, the operation of such bridges involves a combination of hydraulic jacks and, in certain instances, electronic systems that facilitate this height adjustment. The incorporation of these innovative bridges has transformed flood management techniques. During flood events, these structures possess the capability to modify their height dynamically, thereby mitigating damage and ensuring the continuous operation of transportation networks. Through the utilization of real-time data analysis, these bridges can elevate in response to rising water levels, thereby enhancing safety and resilience in flood-prone regions.

Applications of Geosynthetics in Highway Pavement
(2019-06-19T10:40:35Z) JAVED, ALI; RAJ, DOMADIYA; AKHILESH, SHETKAR; MOHAN, NAIK
Weak subgrades are a common problem in road construction. Whether it is a temporary access road or a permanent road built over a weak subgrade, a large deformation of the subgrade can lead to deterioration of the paved or unpaved surface. Ground movements caused by swelling /shrinkage of expansive clays poses a threat to any structure resting on such clays. The performance of paved and unpaved road pavements constructed over such expansive soil subgrades is often poor and shows cracking, rutting and differential settlements/ heaving at various locations. Geosynthetics help to distribute the loads more efficiently and increase the effective bearing capacity of the subgrade, hence providing a better alternative to costly conventional stabilization methods. In this study an attempt has been made to stabilize the soil by introducing a single layer biaxial geogrid. Geogrid has been placed in different location and CBR test was carried out to analyze the effect of reinforcing layer and its position on CBR value of the soil. The obtained results showed that there was an increase in CBR with the introduction of geo grid reinforcement in layers and optimum position obtained from the study. From the study it has concluded that increase in number of layers increases the strength of subgrade soil and it can be considered as one of the techniques of Ground improvement by means of reinforcements.

Municipal Solid Waste (MSW) management is one of the vital issues in the contemporary urban environment, more particularly in developing countries. Municipal solid waste generation consists of organic and inorganic waste materials generated by various activities of the society. Improper disposal of solid wastes can pollute all vital components of the environment (i.e., air, land and water). The Bangalore metropolitan (BBMP) area covers an area of 1258 sq km and with a population of about 9.0 million generates around 5000 MT/day of municipal solid waste (MSW) at an average of 0.27 kg/day/per capitaPresently, Bangalore city faced with the problems with such high quantities of solid waste continuously and it is planning to upgrade its management system. The major issues in Bangalore city is open dumping without a liner and without a leachate management facility. The threat of ground water pollution, as well as saturation of an existing landfill site are the most pressing problems for the city today and the basic. Developing countries usually focus on disposal of waste and the most common way is landfill. This cannot only cause decrease of average landfill life but also air pollution and global warming due to the release of CO and CH4 Latest technologies solved this issue by introducing landfill gas based micro turbines and fuel cells The major problems in MSW management at Bangalore are due to the lack of waste segregation at source, and an inefficient and informal recycling system. the treatment of MSW should be effectively safe and most importantly, it should be environmentally sound. Reduction, reuse, recycling, sorting, segregation, processing, and disposing are major steps of integrated waste management. The importance of participatory process of each sector of society to enable waste management socio economically sustainable and ultimately provide an environmentally sustainable solid waste management system. Solid waste management should be incorporated with updated technologies to tackle modern challenges in the field of municipal solid waste and This projects aims in assessing the solid waste disposal techniques in Mahadevapura zone and also provide some improvement techniques for more efficient disposal of Solid waste
Assessment of Surface and Sub Surface Water Quality in Bellandur Village
(2019-06-19T09:49:35Z) CHAITHANYA; MANOJ; MALYADRI; GANGADHAR
Water is an important resource for the domestic, agricultural and industrial purposes. Though in our country, we have good rainfall, its availability in space and time is not adequate enough to meet the various requirement of the people who are living in every region. With proper management of available water resources, it is possible to meet the minimum requirement of the human beings. While the quantity of water available is restricted in certain areas, wherever the water is available, its quality is making it un useable. Therefore, both quantity and quality of water are important while considering the availability of water resources in Bengaluru. The water requirement for domestic, industrial and other uses in cities and towns is difficult to meet at all times. While the major cities are being supplies water from surface water sources, the town and the villages in the maidan region are exclusively dependent on the ground and surface water for their domestic requirement. Even in places where the surface water is provided for drinking water purposes, partially ground water resources are tapped for domestic requirement in these cities and towns. In big cities such as Bengaluru, Mysore, Mangalore, Davanagere, Hubli, Dharward, Gulbarga, etc., ground and surface water is extensively exploited to meet the domestic requirement of water.

(2020-09-22T10:40:03Z) MOHAMMED, K.P; O.K., CHAND; PRASANNA KUMAR, REDDY
The role of water bodies have been realized traditionally ages ago and was used for domestic and irrigation purposes. Due to increased urbanization and unplanned development led these water bodies receiving untreated sewage. A physico-chemical analysis of sewage fed VARATHUR lakeLAKE in Bengaluruanglore was carried out and its treatment capability in terms of Biological Oxygen Demand (BOD) removal, Nutrient assimilation and Sself remediation were assessed. During the last 5 decades, increased urbanization, and unplanned development, has led to the deterioration of these water bodies by sewage ingress. These are being increasingly used for disposal of untreated sewage. This has enriched the system with nutrients leading to eutrophic status which poses a serious threat to the quality and very existence of life. The present work focuses on one of the urban water bodies in Beangaluorue, and involves characterization of the water body nutrient budgeting well as assessing the treatment capabilities in terms of BOD removal, ph, TDS, etc..

Due to scarcity of petroleum and coal it threatens supply of fuel throughout the world also problem of their combustion led to research in different corners to get access the new sources of energy, like renewable energy resources. Solar energy, wind energy, different thermal and hydro sources of energy, biogas are all renewable energy resources. But, biogas is distinct from other renewable energies because of its characteristics of using, controlling and collecting organic wastes and at the same time producing fertilizer and water for use in agricultural irrigation. Biogas does not have any geographical limitations nor does it requires advanced technology for producing energy, also it is very simple to use and apply
Biogas Production from Anaerobic Digestion using Sewage Sludge
(2018-06-21T07:59:43Z) Adel, Jeelani; Khalid, Ajaz; Kumar, Shivankar; R K, Pintu
Biogas production requires anaerobic digestion. The anaerobic digestion of kitchen waste produces biogas, a valuable energy resource. Anaerobic digestion is a microbial process for production of biogas, which consists of primarily methane (CH4) & carbon dioxide (CO2). It is further facilitated by addition ofinoculum i.e. sewage sludge. The wastes produced in the college premises is dumped which is not utilized and proves to be a nuisance to the environment. Hence this waste was used for biogas generation. Preparations were for the installation setup where the generation of biogas was measured and different laboratory tests were carried out. The continuously-fed digester requires addition of sodium hydroxide (NaOH) to maintain the alkalinity and pH to 7. The digester was seen to have a temperature of 30°C mesophilic range
A Case Study of Qualitative and Quantitative Analysis of Bellandur Lake Water
(2016-06-22T13:33:35Z) Aditya, Barrela; Piyush, Bazimaya; Subhash, Adhikari; Ngehang, Nogbi
Most lake pollution problems are caused by nutrients, contaminants, and sediments carried into the lakes. Soil particles carry more than 90 percent of the organic nitrogen and phosphorus originating from upland agricultural practices (Wilkin and Hebel, 1982). Sediments come from all over the land and thus have nonpoint sources, whereas nutrients can have both nonpoint and point sources. In a typical watershed, nutrients may come from sewage, wastewater, agricultural and urban runoff, and atmospheric fallout. In recent years, heavy use of fertilizers and pesticides and high rates of soil erosion have increased the severity of the problem. High concentrations of nitrogen and phosphorus are the main causes of algal growth, which results in the deterioration of the lake water quality. Algae have a very high growth potential, many times more than any land-based plant system, and respond quickly to nutrient inputs which act as fertilizers. Water pollution has been a major issue as water forms an important component of our day-to-day activity. Excess nutrients either from sewage discharge, industrial discharge or agricultural runoff add to the imbalance in the dynamics of water quality. Bellandur Lake occupies 4.8% of city area and maximum sewage entering the lake is 600 MLD.

Analysis for both techniques has been executed using ETABS software.
Comparative Analysis of a Multistoried Building with and without Shear wall using STADD Pro.
(2018-06-22T09:18:43Z) Sumith, B N; Prashanth, G M; Sangamesh
In the seismic design of a multi storey building To ensure the stability against the lateral force caused by earth quake various methods are used, the most commonly used method is provision of shear wall to the building. The reinforcement concrete shear wall is the most reliable method of construction of shear wall which make the structure resistant against lateral forces, as it imparts stiffness to the structure and provides enough strength which minimises the damages caused by the earthquake. In this paper three models are analysed one without shear wall and two with shear wall at different location, one at the corner and one with shear wall at the faces and core of the building through STAAD Pro. Equivalent static method is used for software validation and response spectrum method is used for comparison of three models
