Rainwater harvesting is a technology used to collect, convey and store rain for later use from relatively clean surfaces such as a roof, land surface or rock catchment. The water is generally stored in a rainwater tank or directed to recharge groundwater. Rainwater infiltration is another aspect of rainwater harvesting playing an important role in storm water management and in the replenishment of the groundwater levels. Rainwater harvesting has been practiced for over 4,000 years throughout the world, traditionally in arid and semi-arid areas, and has provided drinking water, domestic water and water for livestock and small irrigation. Today, rainwater harvesting has gained much on significance as a modern, water-saving and simple technology.

The practice of collecting rainwater from rainfall events can be classified into two broad categories: land-based and roof-based. Land-based rainwater harvesting occurs when runoff from land surfaces is collected in furrow dikes, ponds, tanks and reservoirs. Roof-based rainwater harvesting refers to collecting rainwater runoff from roof surfaces which usually provides a much cleaner source of water that can be also used for drinking.

Is Your Home Earthquake Resistant?

Technical paper Presented by:
Mr.Jismon Issac B.E (Mech) A.I.E, MBA

Over the past few years, India has seen a spurt in the vertical growth of buildings. They range from individual houses to very tall skyscrapers. Whenever news on earthquake is reported, we have only one question in our mind – Is our home safe during an earthquake?

Engineers always tell us that earthquake don’t kill, but that will be done by poorly built constructions. Earthquake resistant buildings can be made, only by constructing our homes with ductile character. For a better understanding in earthquake resistant buildings, we must acquire knowledge about earthquakes and its occurrence. The points are given as below;

The Rivers form a city’s lifeline and no other city in the country can boast of having three Rivers running through it. Karha riverfront in Baramati City is a multifunctional riverfront with majority of premises being used as Residential, Irrigation,Indusrial Recreational purposes.

The water quality of the Karha River is very low due to a large amount of untreated sewage being let into the river. Other major problem pertaining to Karha river is flooding of the river.

The project work aims to carrying out suitable river-training works and measures to reduce the river pollution, restore and maintain the river ecosystem as well as riparian ecosystem.

The aim of this project would be transform Baramati as a unique cultural platform with recreational and entertainment facilities serving the city.

High Performance Concrete – Methods for preparation, Advantages and Drawbacks

High performance concrete provides high durability, strength, low water-cement ratio and longer life span of the structure. Special ingredients such as plasticizers, optimum aggregate size and fiber steel reinforcement are used to make this type of concrete admixture. This type of concrete type is used in special and complex construction structure such as bridges and tunnels. High performance concrete also helps in reducing the duration of the project, as there is low water cement ratio in making the admixture for the concrete. This type of concrete is useful for fast track construction where owner required the possession of the property as soon as possible. High performance concrete have several advantages over traditional Portland cement concrete.

First, high performance concrete provides better strength and durability. Water cement ratio majorly affect the workability of the concrete (Naik et. Al., 2012). According to Naik et al., (2012, p. 463), increase in the water cement ratio, which can be obtained by increasing the water content in the concrete admixture, increases the workability and slump ratio of the concrete.

This study introduces a new approach for seismic assessment of existing school buildings. The proposed approach requires minimum human effort as it can be implemented by a small team of technical construction background. The approach is based on EMS-98 scale in addition to rapid survey of architectural and structural elements of existing school buildings. The study uses 64 selected public school buildings sampled from a total of 364 schools in Gaza Strip. The results showed that 50% of the surveyed schools are classified as Vulnerability class B, while 20 % are classified as Vulnerability Class A. The results were verified using the ‘probability matrix damage’ approach and showed good satisfying convergence. The results of the study are beneficial for the responsible parties who are expected to take appropriate actions related to enhancing seismic performance of Gaza Strip schools against seismic activities, due to the fact that these school buildings not only host about 450,000 students and teachers, but also serve as emergency shelters for those who lose their homes as a result of political instabilities in the region.
