Implementation, Design, And Cost Analysis Of A Concrete Washout System, Omar Adina
Implementation, Design, And Cost Analysis Of A Concrete Washout System, Omar Adina
BioResource and Agricultural Engineering
With the increase of environmental pollution in today’s world, many strategies and regulations are being enforced. These enforcements come from the state and federal governments, but public awareness is often overlooked. Stormwater regulations here in California have dramatically changed over the last decade, as the topic is investigated more often.
This senior project encompassed the design prototype and cost analysis of a permanent concrete washout station for the BioResource and Agricultural Engineering Department at California Polytechnic State University, San Luis Obispo. The design parameters given were to construct a steel bin for the excess concrete to be dumped into during …

Application Of A Heuristic Method To A Water Distribution System For Determining Optimal Water Quality Monitoring Locations, Lawrence David Johnson
Application Of A Heuristic Method To A Water Distribution System For Determining Optimal Water Quality Monitoring Locations, Lawrence David Johnson
Master's Theses
Although regulations and requirements for water quality source monitoring have increased, drinking water distribution systems can still be considered vulnerable to purposeful or accidental contamination.
This study analyzes the transport of the hypothetical contaminant Cryptosporidium through the distribution system of a city with a population of 30,000 to 50,000 in an attempt to locate the optimal monitoring locations in the distribution system. Cryptosporidium was selected due to its resistance to chlorine and it’s conservative properties for vulnerability assessments. The method for selecting the optimal monitoring locations was taken from Chastain (2004) which developed and examined the method for a virtual …
Residential Water Conservation: A Cross Comparative Analysis, Jeffrey M. Cook
Residential Water Conservation: A Cross Comparative Analysis, Jeffrey M. Cook
Master's Theses
This thesis will explore different water conservation strategies and systems in the residential home, using the city of Irvine as a basis. The thesis will compare the financial implications between the different systems and as a return on investment. The analysis will also account for ecological and social implications on the occupants, in particular their standard of living and lifestyle changes. The thesis will explore the ability to conserve water in new residential construction and will provide a sustainable and conscientious schematic water design for the particular area of concern.
This thesis will act as a preliminary case study for …
Portable Solar Desalination System, Genaro Sanchez, Alan Galarza, Erick Del Real
Portable Solar Desalination System, Genaro Sanchez, Alan Galarza, Erick Del Real
Electrical Engineering
Clean water and reliable energy can be difficult to obtain in remote locations such as desert villages, secluded islands, and other places where no fresh water can be found. The primary goal for this project is address these problems by implementing a portable desalinization plant system that is to be powered by solar energy PV system as the main energy source.
Sustainable Agriculture: A Time For Education, Kortnie Millhouse
Sustainable Agriculture: A Time For Education, Kortnie Millhouse
Agricultural Education and Communication
This study used a fifteen-question survey to identify the articulation between education of water quality practices and the willingness to implement sustainable water quality techniques on farmland according to twenty-five agricultural operations residing on the Central Coast. Questions one through eight asked respondents to indicate their agreement or disagreement with various water quality assessment tools. Questions nine through twelve asked respondents to personally rate their operation’s level of water quality management on a scale from one to ten. Questions thirteen through fifteen were open-ended questions to generate responses about demographics. Consensus was reached that the higher the level of education …
Evaluation And Design Of A 20-Acre Avocado Orchard, Daniel Holtz
Evaluation And Design Of A 20-Acre Avocado Orchard, Daniel Holtz
BioResource and Agricultural Engineering
Rocky H Ranch is a 120 acre avocado farm located in Escondido California. There is a 20 acre parcel that has not been planted. The roads, trees, and irrigation system were designed to maximize yields and irrigation system performance while utilizing the latest technology.
Roads were laid out along the contours to maintain block sizes to an average length and width. This is done for two reasons, ease of harvesting and so the irrigation laterals are not excessively long. Nine blocks, or where roads surrounded trees, were created. The trees were laid out along the contours at a 15 foot …

Design, Fabrication, And Evaluation Of An All-Grain Brewing System, Alex Jensen
Design, Fabrication, And Evaluation Of An All-Grain Brewing System, Alex Jensen
BioResource and Agricultural Engineering
A propane burner system was design for to use with an existing all grain brewing system. The use of a pump was used to create a recalculating mash system. The evaluation of the entire system included determining the amount of potential sugars which could be extracted from the malted grains and comparing them to the actual amount of sugar extracted prior to fermentation. An expected value was achieved. Another analysis looks at how efficient the system was at turning the total water used into a drinkable final product.
Effect Of Water On Micronutrient Content And Yield In Rice (Oryza Sativa L.), Sheila Lorraine Baker
Effect Of Water On Micronutrient Content And Yield In Rice (Oryza Sativa L.), Sheila Lorraine Baker
Master's Theses
Rice (Oryza sativa L.) is an important crop in many countries. According to the IRRI, more than 2 billion people globally depend on rice as a staple food (Dawe, et al. 2003). Studies on micronutrient content in rice and the effect of water in availability of the nutrients may aid in decreasing global nutrient deficiencies. Rice is grown under different water regimes such as AWD and intermittent flooding, sprinkler and furrow irrigation. A greenhouse pot experiment of rice utilizing a split plot design under different water regimes was conducted to assess the affect of water on (1) DTPA extractable soil …
