WATER QUALITY ASSESSMENT IN URBAN WATER SUPPLY SYSTEM
Chapter One:
Introduction
1.1 Background to the Study
Water is an essential natural resource for all forms of life, and access to clean and safe drinking water is crucial for human health, socio-economic development, and environmental sustainability. In urban areas, where population density is high, the demand for potable water often outstrips supply, leading to concerns over water quality. Urban water supply systems, which include reservoirs, pipelines, treatment plants, and distribution networks, are designed to provide safe drinking water to residents. However, the effectiveness of these systems is highly dependent on the quality of the water and the infrastructure involved in its delivery.
Water quality refers to the physical, chemical, biological, and radiological characteristics of water, which determine its suitability for drinking, industrial, recreational, and agricultural uses. In urban areas, various factors affect water quality, including pollution from industrial discharges, domestic waste, agricultural runoff, and the overall integrity of the water supply infrastructure. Consequently, water contamination remains a significant public health concern, particularly in cities with rapidly growing populations, aging infrastructure, and inadequate water treatment processes (Adeleke et al., 2020; WHO, 2017).
Urban water supply systems face unique challenges in maintaining high water quality, such as the intrusion of contaminants into the water supply due to leaks in pipes, improper waste disposal, and insufficient monitoring of water treatment processes. The quality of water may also be influenced by seasonal changes, weather patterns, and human activities, which can lead to fluctuations in the levels of harmful substances like bacteria, heavy metals, and chemicals in the water (Ogunbiyi et al., 2021). This makes it essential to regularly assess the quality of water in urban supply systems to ensure public health and environmental sustainability.
Water quality assessments involve the systematic collection of data on water samples from various points in the distribution system, followed by laboratory analysis to measure parameters such as pH, turbidity, temperature, dissolved oxygen, heavy metals, microbial content, and the presence of harmful chemicals (Olayemi & Oyedepo, 2020). Through regular monitoring and assessment, potential threats to water quality can be identified, and corrective measures can be taken to prevent waterborne diseases and pollution-related health problems (Akanbi et al., 2018).
In Nigeria, where urbanization is increasing rapidly, water quality management remains a significant challenge. Inadequate infrastructure, pollution from domestic and industrial sources, and climate change have compounded the problems of providing safe drinking water in urban areas (Akinyemi et al., 2021). Therefore, it is important to assess the water quality of urban water supply systems to ensure the provision of safe and sustainable water sources for urban populations.
1.2 Statement of the Problem
The growing concern over waterborne diseases in urban areas is directly linked to the poor quality of water supplied to residents. In many urban centers, the water supply systems face challenges such as contamination, inadequate treatment, and aging infrastructure, leading to the deterioration of water quality. In some cases, residents of urban areas rely on untreated or poorly treated water, which may lead to the outbreak of diseases like cholera, dysentery, and typhoid (Olumide & Adeyemi, 2019).
Despite the presence of water treatment plants in urban areas, the quality of drinking water is often compromised by the lack of efficient monitoring systems, poor maintenance of infrastructure, and the intrusion of contaminants during distribution (Soyinka & Adeoye, 2020). This study aims to evaluate the water quality in the urban water supply systems of [insert location], focusing on the identification of key contaminants, sources of pollution, and the overall effectiveness of existing water treatment processes.

BAGGAGES COLLECTION TREATMENT AND DISPOSAL IN OREDO LOCAL GOVERNMENT AREA, BENIN CITY EDO STATE, NIGERIA
ABSTRACT
Worldwide, solid waste generation has steadily increased as a result of global changes associated with population, consumption and industrial development. The world cities generate about 1.3 billion tonnes of solid waste per year and this volume is expected to increase to 2.2 billion tonnes by 2025 (Ayanshola, 2013). Thus, the importance of waste collection, transfer and disposal remains and the need for long-lasting solutions.
Nigerian cities and towns have continued to grapple with the reality of how best to manage the growing municipal solid waste stream as population grows
This work discusses baggages collection treatment and disposal in oredo local government area, benin city edo state, nigeria
.A hundred and twenty questionnaires were distributed among students and teachers from selected secondary schools in Nigeria. Interviews and surveys were also conducted.
Primary and secondary data will be used in the analysis. Tables and percentages will also be used as the instrument of analysis
It will be observed therefore that effective baggages collection, treatment and disposal will have a strong and significant positive impact on public health safety, and environmental management. There is a strong negative relationship between poor management of baggage collection, treatment and disposal. Poor waste management are causative factors for disease outbreaks and epidemics. It is recommended that government agencies innovate procedures and strategies to better baggage waste management, adequate funding from government should also be earmarked to implement much needed waste management practices.

A STUDY OF THE EFFECT OF LAND FILL SITES AND MANUFACTURING COMPANIES ON AIR QUALITY
ABSTRACT
This work is a study of the effect of land fill sites and manufacturing companies on air quality. Waste management (WM) is a demanding undertaking in all countries, with important implications for human health, environmental preservation, sustainability and circular economy. The method of sanitary landfilling for final disposal of waste remains a generally accepted and used method but the available scientific evidence on the waste-related environmental and health effects is not conclusive. Manufacturing companies emit large fumes and wastes into the air thereby polluting it and making it less pure.
.A hundred and twenty questionnaires were distributed among people from selected states in Nigeria who live or run businesses close to landfill sites. Interviews and surveys were also conducted.
Primary and secondary data will be used in the analysis. Tables and percentages will also be used as the instrument of analysis
It will be observed therefore that land fill sites and manufacturing companies have a strong and significant negative effect on air quality

THE ENERGY SAVINGS AND ENVIRONMENTAL BENEFITS OF WASTE WATER TREATMENT AND REUSE
Abstract
This work discusses the energy savings and environmental benefits of waste water treatment and reuse.
Wastewater treatment plants (WWTPs) consume high amounts of energy which is mostly purchased from the grid. During the past years, many ongoing measures have taken place to analyze the possible solutions for both reducing the energy consumption and increasing the renewable energy production in the plants. This review contains all possible aspects which may assist to move towards energy neutrality in WWTPs. The sources of energy in wastewater were introduced and different indicators to express the energy consumption were discussed with examples of the operating WWTPs worldwide. Furthermore, the pathways for energy consumption reductions were reviewed including the operational strategies and the novel technological upgrades of the wastewater treatment processes. Then the methods of recovering the potential energy hidden in wastewater were described along with application of renewable energies in WWTPs. The available assessment methods, which may help in analyzing and comparing WWTPs in terms of energy and greenhouse gas emissions were introduced. Eventually, successful case studies on energy self-sufficiency of WWTPs were listed and the innovative projects in this area were presented.

EVALUATION OF WATER QUALITY MODELLING PARAMETERS-TOWARDS THE EVOLVEMENT OF REAERATION COEFFICIENT FOR RIVERS IN NIGERIAN ENVIRONMENT
CHAPTER ONE
INTRODUCTION
1.1 Background of Study
When a lake or river becomes stratified, many changes in the physical, chemical and biological characteristics of the water can occur.
These changes are often undesirable for many reasons, in the hypolimnion (lower layer) of the stratified lake, oxygen levels are lower, nutrient concentration higher and temperature less than in the epilimnion (upper layer). Water withdrawn from the hypolimnion for domestic and industrial usage needs more treatment to remove nutrients and add oxygen. Treatment costs are thus higher. Reducing conditions present in the hypolimnion change the chemistry: oxidation products are no longer released and instead large volumes of hydrogen sulphide and methane may be produced; anaerobic conditions may prevail such that aerobic bacteria and respiring organisms are replaced by anaerobic bacteria; the rate of release of phosphates from the sediments is increased by a large percentage.
Oxygen transfer at the surface of lakes and streams is an effective process for the environmental quality of the aquatic ecosystem; in fact, oxygen transferred from the atmosphere by means of natural reaeration replaces the amount consumed due to oxidation of organic mater discharged into the water body. Otherwise, if the dissolved oxygen (DO) levels drops below acceptable values, aquatic ecosystem health could be seriously impaired and desirable uses of water resources could be precluded. Therefore, water quality standards and criteria for DO are provided by environmental regulation of many countries, such as USA, UK, Germany, Italy and Japan; in Italy,D.L.152/1999 has recently established for streams and lakes a classification system which considered
Dissolved Oxygen (DO) as key water quality parameters (Ciaravino and Gualtieri; 1999). General speaking, DO levels are the result of an interaction among processes, i.e., sources and sinks which affect DO concentration; the first one, such as atmospheric reaeration and photosynthetic production, tends to increase oxygen levels, while the second ones, such as oxidation of carbonaceous and nitrogenous wastes material, respiration of aquatic plants and Sediments Oxygen Demand (SOD) produce a decrease of DO concentration; each one of these phenomena can be expressed through a different kinetic expressions in order to quantify its effect. Reaeration, that is, the physical absorption of oxygen from the atmosphere by water, is the most relevant natural means by which a water body may recover DO concentration; thus, reaeration amount should be carefully estimated. Several empirical equations have been proposed in literature and some of these ones are widely applied in water quality studies, but recent investigations have demonstrated that they generally result in a poor fit with field data (Melching and Flores, 1999; Gualtieri and Ciaravino,1999). In fact, most of the equations are derived from relatively small set of laboratory or field data for a relatively localized group of streams; so that, if they are applied to other field data different from which they were developed, they provide a poor estimation; moreover, most of them were developed using field data obtained by the dissolved oxygen-balance, which is generally affected by high errors. Thus, none of available equations appears to be applicable to all steam hydrodynamic conditions, but, on the contrary, they remain stream-specific, probably since some parameters involved in this process have been neglected in their formulation.
Furthermore, oxygen dissolves by diffusion from the surrounding air; aeration of water that has tumbled over falls and rapids; and as a waste product of photosynthesis. A simplified formula is given below:
Photosynthesis (in the presence of light and chlorophyll)
Carbon dioxide + Water Oxygen + Carbon-Rich foods
CO2 H2O O2 C6H12O6
Fish and aquatic animals cannot split oxygen from water (H2O) or other oxygencontaining compounds. Only green plant and some bacteria can do that through photosynthesis and similar processes. Virtually all the oxygen we breathe is manufactured by green plants. A total of three-fourth of the earth‟s oxygen supply is produced by photosynthesis in the ocean.
If water is too warm, there may not be enough oxygen in it. When there are too many bacteria or aquatic animals in the area, they may overpopulate, using DO in great amount. Oxygen levels also can be reduced through over fertilization of water plants by runoff from farm fields containing phosphates and nitrates (the ingredients of fertilizer). Under these conditions, the numbers and sizes of water plants increase. Then, if the weather becomes cloudy for several days, respiring plants will use much of the available DO. When these plants die, they become foods for bacteria, which in turn multiply and use large amount of oxygen and thus depleting the oxygen. How much DO an aquatic organism needs depends upon its species, its physical state, water temperature, pollutants present, and so on.
Consequently, it is impossible to accurately predict minimum DO levels for specific fish and aquatic animals. For example, at 50C (41oF), trout uses about 50-60 milligram (mg) of oxygen per hour, at 25oC (77oF), they may need five times that amount. Fish are coldblooded animals. They use more oxygen at higher temperatures because their metabolic rates increase.
Numerous scientific studies suggest that 4-5 parts per million (ppm) of DO is the minimum amount that will support a large, diverse fish population. The DO levels in good fishing waters generally averages about 9.0 parts per million (ppm).
The environmental impact of dissolved gas is as explained below. Total dissolved gas concentration in water should not exceed 110 percent. Concentration above this level can be harmful to aquatic life. Fish in waters containing excessive dissolved gases may suffer from “gas bubble disease”; however this is a very rare occurrence. The bubbles or emboli block the flow of blood through blood vessels causing death of the aquatic organisms. External bubbles (emphysema) can also occur and be seen on the fins or skin and on other tissues. Aquatic invertebrates are also affected by gas bubbles disease but at level higher than those lethal to fish.
Adequate dissolved oxygen is necessary for good water quality. Oxygen is a necessary element to all forms of life. Natural streams purification processes require adequate oxygen levels in order to provide for aerobic life forms. As dissolved oxygen levels in water drops below 5.0mg/l, aquatic life is put under stress; the lower the concentration, the greater the stress. Oxygen levels that remain below 1-2mg/l for a few hours can result in a large fish kill.
Biologically speaking, however, the level of oxygen is much more important measure of water quality than faecal coliform. Dissolved oxygen is absolutely essential for the survival of all aquatic life.
Moreover, oxygen affects a vast number of other water indicators, not only biochemical but esthetic ones like odour, clarity and taste. Consequently, oxygen is perhaps the most well established indicator of water quality.
Dissolved oxygen affects water quality in that a high DO in community water supply is good because it makes drinking water tastes better. However, high DO levels speeds up corrosion in water pipes, for this reason, industries use water with the least possible amount of dissolved oxygen.
