Catalog Description Water Systems Design (3:3:0). Prerequesite: CE 3305, Hydraulic analysis and design of municipal water distribution, stormwater collection, and wastewater collection systems. Oral and written presentations. (Writing Intensive)
Objectives Application of hydraulics in water distribution and collection systems – learn how to use predictive tools such as charts and computer programs – apply these tools to the analysis and design of distribution and collection systems. Prepare professional reports and presentations
Expectations During this course the student will 1.Read, synthesize, and communicate ideas presented in current and historical technical literature. 2.Perform ﬂow and transport computation in simplistic topologies using Excel or a calculator. 3.Perform ﬂow and transport computation in realistic geometries using EPA-NET or similar professional tools for water distribution systems.
Expectations (Continued) 4.Perform ﬂow and transport computation in realistic geometries using SWMM 5.0 or similar professional tools for stormwater and wastewater collection systems. 5.Size and select engineering materials (pipes, pumps, valves, etc.) for use in the drinking water environment (water distribution), the stormwater environment, and the wastewater environment.
Expectations 6.Prepare professional reports for the design of a drinking water distribution system, a stormwater collection system, or a wastewater collection system.

Course Server Nearly everything needed is on server or internet
Water Control Systems Systems to manage spatial and temporal distribution of surface runoff from rainfall events (drainage engineering) – Flood control – Storm water harvesting Capacity is based on AREA served – hydrology dominated designs
Water Use Systems Systems to manage spatial and temporal distribution in support of human habitation – Water supply/treatment/distribution – Waste water collection/treatment/discharge Capacity is based on POPULATION served – hydraulic dominated designs
Environmental Restoration Systems Systems to manage spatial and temporal distribution in support of non-human habitation – Create “desirable” conditions “Desirable” <= Policy <= Value Judgment
Brief History of Water Systems This brief history is adapted from – “Historical Urban Water Systems” by Dr. Robert Pitt, Department of Civil and Environmental Engineering, University of Alabama, Tuscaloosa, AL As we proceed through the history, consider whether the picture is a water control, water use, or environmental restoration system.

Frequency Based Design Design to accommodate an event of some pre-determined probability (return frequency). – Assume that more frequent events are also accommodated. You did frequency analysis in hydrology! T-year event
Risk Based Design Design to accommodate some pre-determined expected net loss. – Expected loss is product of the probability of failure and the cost of that failure. Design to minimize the sum of initial cost and expected loss You did elements of risk analysis in hydrology, namely the probability portion.
Critical-Event Design Design to accommodate largest anticipated event. – Applied for systems where consequences of failure are huge (economically and/or politically) – Large dams, nuclear power plants Assumes the event is anticipated – Earthquake + Tunsami + Pump Failure combined were not anticipated (actually they were, just no- one paid attention!)
Hydrologic Data Design uses hydrologic and geologic data and various analysis tools – USGS: topography, streamflow, computer programs – NRCS: soil maps, land use, computer programs – US EPA: rules, chemical properties, computer programs – NCDC: rainfall, snowfall, solar radiation – USBR: Western US water and energy supply – USACOE: Navigable waterways, computer programs – FHWA: design manuals, computer programs
Hydrologic Data Design uses hydrologic and geologic data and various analysis tools – TWDB: Funding (for cities and water districts) – TCEQ: Rules, guidelines, some data – TNRIS: Evaporation estimates, digital elevation models, digital ortho-quadrant maps, false IR images, etc. – TxDOT: Design manuals, some data, computer programs – County: Rules, design manuals, some operate rainfall-stage networks – Cities: Rules, design manuals
Hydrologic Data Design uses hydrologic and geologic data and various analysis tools – River authorities – Drainage districts – Flood control districts – Irrigation districts – Council of Governments (COGs)
Data Most data are NOT free – Agencies charge a fee for data, usually pretty small. – NCDC is worst offender of taking the fee, then providing the wrong data, so be sure you know what you want. – A lot of useful data are currently free, but don’t get offended if in the future you are expected to pay for it.
