Description

This module introduces flow concepts used for the design of water supply and drainage systems. The module will also examine issues relating to the maintenance and management of waste water drainage systems and water distribution networks.

Learning Outcomes

On completion of this module the learner will/should be able to;

1.

Define and manipulate the theoretical concepts which underline basic fluid properties.

2.

Identify and understand the components of  water supply systems and foul water drainage networks.

3.

Understand the concepts and techniques associated with water supply system maintenance and management.

4.

Understand the concepts and techniques associated with foul and mixed sewer drainage systems maintenance and management. 

5.

Complete a case study project on improving a waste water drainage network or water supply network in your care. 

Teaching and Learning Strategies

This module will introduce steady flow concepts to students through on-line learning. The students will be required to carry out a project which will require the design of a water supply system and surface water drainage system inclusive drainage elements for a proposed development.

Module Assessment Strategies

Case Study Project, Multiple Choice Question Assessments, Final Exam. 

Repeat Assessments

The student shall be required to resubmit the case study project (if failed individually) and repeat the written exam.

Indicative Syllabus

1) Introduction.

Basic fluid properties, units of pressure (Pa, Bar, Psi), conversion between units of pressure to pressure head (m), pressure measurement gauges, pipeline pressure capacity, pressure loss in pipelines, concept of hydraulic gradient. Concept of flow rate and  units of flow rate (m3/s, gal/min). The concept of unsteady flow and associated surge pressures. Cavitation of fluids and its application to water distribution networks.  Flow under gravity, open channel flow. Foul water and surface sewers v's water main pressurised pipelines. 

 

2) Water distribution system components.

Pipeline types, sizes ( Cast iron, Ductile Steel, HPPE, HDPE, Asphaltic Concrete , etc) and where they are typically or historically have been used.  Pipeline fittings and their functions (SV, AV, PRV, HYD etc). Typical water distribution network layout. Typical pipeline, fitting and connection details. Rising main pumped systems, in-line booster pumps. Typical pump maintenance issues. Energy cost associated with pumping. Surge tanks (pressurised and atmospheric). Flow meters and their operation  (Bulk flow meters, district flow meters, domestic flow meters).

 

3) Water distribution system management and maintenance.

The concept of District Metered Areas (DMA's). Definition of passive and active leakage. Leakage assessment and testing techniques. Pipeline repair and replacement  techniques (pipe lining, pipe bursting, pipe replacement etc). Pressure testing on installed and repaired pipelines. Pressure management and control. Post leakage repair assessment. Customer side leakage assessment.  Flushing techniques in water supply networks.  The cost of producing and supplying water.  The cost of water leakage and wastage.  

 

4)  Foul and mixed strom water collection systems.

Pipeline and culvert types (concrete, uPVC,, brick, clay etc. ) and where they are typically or historically have been used.  Typical waste water and mixed sewer drainage network details and layout.  Typical pipeline, manhole and connection details. Foul water pump sump design and layout (dry well and wet well) .  Foul water rising main layout and details. Flow measurement techniques in open channels and pipelines ( Flumes, thin plated weirs, orifice flow) . Typical minimum and maximum sewer pipeline sizes and slopes. The concept of Dry Weather Flow (DWF) and Design Flow (DF) in sewers.

 

5)  Foul and mixed strom water collection system maintenance and management.

Sewer infiltration estimation and assessment. Sewer rehabilitation and replacement  techniques.  Safety issues associated with entering and repairing live foul and mixed storm sewers. Sewer testing and survey methods. The cost of collecting and treating foul sewage and the implication of infiltration. Storm water overflow, storm emergency overflow, strom water storage, storm water chambers, strom water overflow controls.
