Even today, many villages including Chityala, Nandigudem, Vadalakunta, Bhimolu, and Saggonda in Andhra Pradesh State are suffering adversely by the absence of this network. So, the Government of Andhra Pradesh is considerate to provide a suitable Domestic Water Supply Network for all these villages, to put forth this issue, through Andhra Pradesh Water Supply Scheme. Therefore, this study aims to design a simple and economical water supply network, with a high end precision and simplicity, in Chityala, Nandigudem, Vadalakunta and Bhimolu villages using EPANET 2.0 Software based on their Digital Global Positioning System (DGPS) Survey Data and Population Data. The designs are proposed based on the hydraulic parameters that are enumerated using the same software. Also, by calculating the minimum volume of water lost as head loss using Hazen-William's Equation. This study is worked intensively in designing the networks to suit the needs and criteria of Government of Andhra Pradesh. It is also intended to surpass the disastrous situation facing by the citizens of those villages, as a small contribution towards the scheme.

Particularly under conditions of loading, these soils are highly prone to fail due to shear, crushing or excessive settlement. These factors end up expansive soils as unsuitable soils for any construction. If the strength of the soil is poor, then soil stabilization is duly needed. Stabilization is a technique used for improving characteristics of native and weak soils. It can also help in modifying the properties to improve its engineering performance both in terms of strength and durability. Ultimately, this operation helps the weak soils suitable for the purpose of construction and makes it resistant against shear failure. There are numerous stabilizers used for soil stabilization. In the present case study, we are using the materials fly-ash and cement to stabilize the expansive soils and observe what is the optimum percentage that these materials should be used to provide maximum stabilization to these soils.

Curing must be undertaken for reasonable period of time, to ensure that the concrete achieves its potential strength and durability. Efficient and uninterrupted curing contributes to the superior quality of concrete. This paper aims to compare the strength parameters of M40 and M25 grade concrete under various methods of curing. For this study, we adopted curing by Immersion and Surface Curing methods. We also adopted Membrane Curing, in which the curing would be done by the application of pigmented emulsions of linseed oil on the concrete surface. Finally, after the concrete specimens have undergone curing for a certain period of time, they are tested for strength parameters such as Compressive Strength and Flexural Strength and the conclusions are drawn from it.

When basalt rock is heated to a molten stage and formed into fibres, it is mixed with epoxy resins and moulded to form basalt rebars. Today, basalt rebars are a part of emerging technology, where their tensile strength is observed around 800-1350 MPa. This study primarily focuses on integrating these basalt rebars into the concrete as a reinforcing material in flexural members and analyzing their behavior in theoretical and functional study relative to conventional HYSD reinforcement. In this study, 2 sets of concrete beam specimens of M25 design mix concrete have been prepared each of size 700 x 150 x 150 mm. One set is made of HYSD reinforcement and the other with basalt rebars, and are subjected to flexure testing, after immersion curing process for 28 days. The various characteristics including maximum load carrying capacities, deflection, flexural strength and first crack point have been observed. Finally, the viability and adaptability for basalt as reinforcement is understood after the test results, in comparison with theoretical analysis.

To overcome this weakness, we generally introduce reinforcement to the concrete. For this study, we are aiming to analyze the strength parameters of concrete under the influence of fibers as a reinforcing material. During the last 30 years, different types of fibers and fiber materials were introduced and are being continuously produced in the market as new applications. Usage of fibers in concrete helps to improve resistance to cracking and fragmentation. For this study, Polypropylene fiber is used as a reinforcing material. We have used M40 and M25 concrete and a comparative study on strength parameters is made with and without the presence of these fibers. The compressive, flexural strength tests were performed by using fiber weight content from 5%.

In this study, M25 grade concrete is used for nominal mix design. High strength high modulus polyester filament yarns are used to study its effects in reinforcing concrete mixes and to obtain basic strength. For the concrete to achieve its maximum strength and longevity, curing must be carried out for a suitable period of time. In this study, the curing is done by preventing excessive loss of moisture from the concrete either by leaving formwork in place, covering the concrete with impermeable membrane after the formwork has been removed by the application of suitable chemical curing agent (water based), or by combination of such methods. Curing by continuously wetting the exposed surface prevents the loss of moisture from it. The compressive, flexural strength tests were performed by placing the textile in the form of layers 1, 2 and 3. As a result, it had been found that the use of polyester textile material considerably increases the flexural strengths. It is also observed that there is a sudden decrease in flexural strength and compressive strength when textile is placed in 3 layers. The maximum flexural and compression strength is obtained by placing the textile in the form of 2 layers and found to be economical. Eventually it has been observed that, there have been an increase in flexural strength for about 48%.

Another important factor, which ultimately and strappingly influences any robust Reservoir and its storage capacity is Sedimentation. Appraisal of quantity of sediment and application of proper remedial measures could significantly sustain and enhance the storage capacity of the reservoir. This study primarily deals on evaluating the annual sediment deposit in Sri Ram Sagar Project’s Reservoir using Arc SWAT (Soil and Water Analysis Tool), a plug-in of Arc GIS 10.4. The attained results from this tool are then compared with Godavari Sediment Year Book (2015-16) for validation. Also, the expedient life of this reservoir is calculated using Gill’s Equation. Eventually, the variance analysis for a difference in deposited sediment and inflow and runoff is evaluated using Anova Analysis and the results are concluded.

This phenomenon makes the path for increase in demand for water globally. The increased consumption for water is leading the path for Global Water crisis. To overcome the future challenges for water and to surpass this problem which is in its initial stage, we have to search for a proper solution. Though the planet Earth possesses about 1385MKm3 of water in various forms, but majority of this water of about 97.1% is in the form of Ocean water, which is Saline by nature and is unfit for consumption for any purpose. So, Ocean water can be used, only after removing that salt content from it.
This study primarily discusses to conduct the process of Desalination using simple resource of Solar Energy. After purifying this ocean water, the water would be subjected to various Physical and Chemical tests and if the test results satisfy the Drinking water standards specified as IS: 10500-2012, then the purified would be fit for consumption, and make a step towards surpassing of the global Water problems.

Hence, the demand for water is increasing significantly. This is leading the way to the crisis of global water. To save ourselves from the potential water problems, we need to find a new approach to allow efficient use of the existing water supply. Around two-thirds of this planet's surface is covered exclusively with the blanket of water, but only 2.5% of this is freshwater and only 0.3% can be considered for use by humans. And the majority of the body of water that is in the form of rivers and seas is either not potable or cannot be ingested due to its salinity. So, Ocean water is a viable solution to cut short our future water issues.
This study primarily focuses on the process of Desalination of Ocean Water using the simple resource of Thermal Energy using Firewood. After the purification, the purified water would be subjected to various Physical and Chemical tests and if the test results satisfy the Drinking water standards specified as IS: 10500-2012, then such water which is purified after the procedures followed would be considered for consumption.

In our Day-to-Day life due to increased consumption of the materials like Plastic, Rubber, Glass in Domestic and Industrial activities in rapidly developing countries like India, USA, Germany etc., it has been creating major harm to the Environment. About 6.3 billion tons of plastic waste, 3.5 billion tons of Rubber waste has been generated in the world so far. If this continues, then our future generations will have to face many serious problems. The probable solutions to reduce their damage to the Environment are either reducing their usage in daily times or recycling them. The first choice is inevitable, as we are habituated using these products. It is possible to adopt the latter. Using proper techniques, Rubber and other materials could be used in construction and other activities by adopting latest technologies. Our research is about, how we could properly use the Scrap Rubber as a Replacement material to Coarse Aggregate in Concrete and minimize the use of Coarse Aggregate. Concrete is a versatile, legendary and supremely strong material which is manufactured with the combination of Cement with Aggregates and Water. It is used in Construction of Structural Elements like Foundations, Columns, Beams and Slabs. It has been ruling the Construction industry since mid 1800‟s.By Replacing Coarse Aggregate with Rubber, it will save the Environment against Pollution from Rubber and Extraction of Aggregates through Quarrying. This will be a major boon towards the Environment. The Concrete obtained by Replacing Coarse Aggregate with Rubber can be called as „‟RUBCRETE‟‟. Cost analysis comparison is also done in this paper for rubcrete concrete and conventional concrete.

Black Cotton soils are highly clayey soils nature (montmorillonite clay mineral). The moisture changes in Black Cotton Soils, compressibility and last-plasticity nature can be greatly improved with the addition of terrazyme. This paper includes the evaluation of soil properties like optimum moisture content, dry density and strength parameter (California bearing ratio valve). Different quantities of terrazyme (% weight) are added to the BC soil and the experiments conducted on these soil mixes. The results show that the use of terrazyme has increased the CBR values i.e., the strength of soil to a great extent.
