💧Design Period in Water Supply Scheme & Factors Affecting Per Capita Water Demand

A well-designed water supply system must ensure safe and adequate water for present and future needs.

Engineers select a suitable design period for each component based on its expected service life, future population growth, and economic considerations.

📌 What is Design Period?

The design period is the future time span for which a water supply system or its components are planned and designed to meet the anticipated water demand efficiently.

📊 Typical Design Period of Water Supply Components

🌊 Source & Intake Structures: 30–50 years

🏗️ Reservoirs: 30–50 years

🚰 Transmission & Distribution Mains: 30–40 years

🏠 Buildings & Pump Houses: 15–25 years

💦 Factors Affecting Per Capita Water Demand

1. 🌡️ Climate – Hot and dry climates increase water consumption.

2. 🏙️ Size of the City – Larger cities generally require more water per person.

3. 👨‍👩‍👧‍👦 Standard of Living – Higher living standards lead to greater water use.

4. 🛁 Habits and Customs – Bathing, washing, gardening, and lifestyle influence demand.

5. 🏭 Industrial & Commercial Development – More industries and businesses increase consumption.

6. ⚙️ Pressure in the Distribution System – Higher pressure often results in higher usage and leakage.

7. 💰 Water Tariff – Lower tariffs encourage greater consumption, while higher tariffs help reduce wastage.

📍 Key Note:

Per capita water demand varies with location, climate, population, economic conditions, and lifestyle.

Accurate estimation is essential for designing an economical, efficient, and reliable water supply system.

👉What Is Traffic Engineering?

•  A branch of civil engineering that deals with the safe, efficient movement of people and goods on roadways.
•  Focuses on road design, traffic flow, signs & signals, and control systems.
•  In Ethiopia, it's guided by ERA manuals and urban traffic policies.

📌 Core Objectives

•  Balance mobility and safety for drivers, cyclists, and pedestrians.
•  Minimize congestion, delays, accidents, and environmental impacts.
•  Optimize intersection design, signal timing, and vehicle capacity.

📌 Key Elements of Traffic Engineering

•  Traffic Flow: Measured using volume, speed, and density (fundamental diagram).
•  Control Devices:
  - Signs (regulatory, warning, guide)
  - Signals (traffic lights)
  - Markings (lanes, arrows, zebra crossings)
• Traffic Studies:
  - Volume counts
  - Speed studies
  - Origin-destination surveys
  - Parking & accident analysis

📌 Intersection & Signal Design

• Controlled using STOP/SLOW signs or traffic lights, based on flow volume.
• Signal timing must consider pedestrian crossing, peak hours, and turning movement.
• Ethiopia uses manuals from ERA and local authorities like AACRA for design specs.

📌 Challenges in Ethiopia

• Narrow roads, poor signage, and weak enforcement affect safety.
• High pedestrian volume in Addis Ababa requires integrated planning.
• Informal public transport (minibus taxis) causes unpredictable traffic flow.

👉Types of Footings (Isolated, Combined, Strip)

📌  What Are Footings?

• Footings are structural base elements that distribute loads to the soil.
• They help prevent settlement and structural failure.
• Chosen based on soil condition, column layout and load.

📌 Isolated Footings (Pad Footings)

• Supports a single column with light to moderate load.
• Usually square or rectangular in shape.
• Used where columns are spaced far apart.
• Common in low-rise buildings across Ethiopian towns.
• Designed based on bearing capacity from EBCS-7.

📌  Combined Footings

• Supports two or more columns with a single footing.
• Used when columns are close or near property line.
• Shape may be rectangular or trapezoidal.
• Ensures even load distribution when space is limited.
• Applied in Addis Ababa’s dense building zones.

📌  Strip Footings (Wall Footings)

• Long continuous footing under load-bearing walls.
• Ideal for buildings with masonry or concrete walls.
• Spreads load over a wider area of soil.
• Common in residential construction in regional towns.
• Easy to construct and cost-effective in clayey soils.

📌Strap Footings (Cantilever Footings)

• Two isolated footings connected by a strap beam.
• Used when column is near boundary but balanced load is needed.
• Strap transfers moment without adding load to soil.

📌  Sloped Footings

• Similar to isolated footing but with sloped sides.
• Reduces concrete volume and improves load path.
• Used where formwork cost is a concern.

📌 Grillage Footing

• Multiple layers of beams used to spread heavy column load.
• Common for steel columns or towers on weak soils.
• Rare in residential work but used in telecom and power sectors.

📌  Mat Footing (Raft Foundation)

• Large slab supporting entire building load.
• Used when soil bearing capacity is very low.
• Common for basements, hospitals and multi-story buildings.
• Recommended in Addis Ababa, Gonder and Jimma clay zones.

📌  Pile Footings (Deep Foundation)

• Long vertical elements that transfer loads deep into ground.
• Used when soil is weak near surface but strong below.
• Applied in bridge abutments and high-rise towers.
• Driven piles or bored piles used based on access.

📌 Pier Footings (Caisson Footings)

• Large diameter bored shafts used like deep columns.
• Provide large load capacity for bridge piers.
• Often filled with concrete and reinforced.

📌 Selection Tips for Ethiopia

• Consider soil test results and bearing capacity.
• Use EBCS-7 for design loads and dimensions.
• Adjust footing depth to prevent moisture and cracking.
• Avoid shallow footings in expansive soils like around Dire Dawa.
• Use reinforced strip footings in seismic-prone areas like Addis Ababa.

👉 Types of Structural Steel Sections

🌟 Overview

• Structural steel sections are shaped and rolled to handle specific loads
• Widely used in frames, bridges, warehouses and high-rise buildings
• Section type affects strength, stability and construction speed

🛠 I-Section (or H-Beam)
• Looks like the capital letter "I" in cross-section
• Used in columns and beams for bending resistance
• Efficient in carrying vertical loads and flexural forces

📐  T-Section (Tee Beam)
• Formed by cutting an I-beam vertically
• Ideal for secondary beams and lintels
• Not strong in lateral torsion but easy to fabricate

📦 L-Section (Angle Section)
• Shaped like the letter "L" with equal or unequal legs
• Common in trusses, bracing systems and towers
• Simple, cost-effective and useful for edge connections

🌍 Hollow Structural Sections (HSS)
• Includes circular, square and rectangular tubes
• Light weight and strong in compression and torsion
• Ideal for frames, poles and aesthetic designs

⚠️ Application in Ethiopia
• EBCS standards recommend I and H sections for most public infrastructure
• L and T sections commonly used in pedestrian bridges and telecom towers
• Hollow sections gaining popularity in urban projects like malls and parking structures

👉Bending Moment, Shear Force & Axial Load

📌 1. Basic Definitions

• Axial Load acts along the member’s longitudinal axis (tension or compression).
• Shear Force resists sliding of one part of a section relative to another.
• Bending Moment causes curvature or rotation within a structural element.

📌 2. Axial Load Effects

•  Compression shortens and thickens members like columns and struts.
•  Tension elongates and thins structural elements like ties or cables.
•  Axial force affects buckling behavior, especially in slender columns.
•  Design is checked per EBCS axial load capacity formulas (ask if needed).
•  Common in trusses, frame members and wall panels in Ethiopia.

📌 3. Shear Force Effects

•  Acts parallel to the cross-section, causing diagonal cracks in beams.
•  High near supports and load application points in simply supported beams.
•  Controlled by web reinforcement or stirrups in RC beams (per EBCS-2).
•  Ethiopian contractors often under-reinforce shear zones—strict inspection needed.
•  Shear failure is sudden and brittle—must be avoided in critical elements.

📌 4. Bending Moment Effects

•  Caused by external loads or support reactions creating rotation.
•  Maximum at mid-span in simply supported beams under uniform load.
•  Positive moment causes sagging, negative causes hogging (upward curve).
•  Bending reinforcement placed at tension face (bottom for sagging).
•  Key in slab design, bridge girders and cantilever balconies in Ethiopia.

📌 5. Combined Actions in Members

•  Real structures often experience all three actions simultaneously.
•  Column with axial load + moment → becomes eccentrically loaded.
•  Beams in frames carry bending + shear and sometimes axial thrust.
•  Load interaction checked using interaction diagrams (from EBCS charts).
•  Bridge design uses envelopes for max/min moment and shear.

📌 6. Practical Ethiopian Applications

•  In telecom towers, tension members carry axial loads from guy wires.
•  Local practice must align with EBCS design limits for safety.
•  Engineers must also consider workmanship—poor concrete leads to failure.
