Reference
INTRODUCTION• About 71 percent of the Earth's
surface is water-covered.
• Water is the driving force of all nature
• Water sustains Life
• What is raw water?
• Water sources
• SDG 2015-2030
PROBLEM STATEMENT
52%39%
9%
Accessability to water
Lack access to pipedor borehole water
Have access toborehole water
Have access topiped water
My design will attempt to solve the issue of accessibility to clean, safe drinking water; reduce water-related diseases; improve livelihood.

OBJECTIVEOverall Objective
• To design a raw water treatment plant that will supply safe and clean water that will meet the demand of people in Njoro area.
Specific Objectives
• To establish the impurities and contamination level in the raw water. (Raw water Quality tests)
• To establish the water utilization/ demand in the area.
• To determine the specifications for the treatment works and related components
Statement of Scope
• Appropriate design model with appropriate design considerations
JUSTIFICATION
Raw water treatment and distribution
•water supply masterplan and design.
Economic development
•Lure investors to the areas.
• Improved living conditons.
• improved agricultural activity
Social development
•An empowered community
•Improved health
•Improved educational standards.
•Reduce child labour

METHODOLOGY1. SITE ANALYSIS
2,490 meters above sea level
177,796 people
10 to 28 degrees
9.3 to 4.1 sunshine hours
400-1200mm
METHODOLOGYMaterials That I Will Use in data collection and analysis
Software
Tools and equipment
3 Sample Cans for water sample
Water Rod
Water Quality Machines:-Electrochemical half cell reaction
RESULTS & DISCUSSIONS3 water Samples taken for test..
The average results shown besides.
The outstanding factor from water quality test is:-
• the high level of Biological pollution in the river water.
•High level of turbidity experienced and colour fail.

SUMMARY• Specific Objective 1: Water Quality Test performed at the University
Water Laboratory helped determine the raw water quality.
• Specific Objective 2: Data (Example Population) I used to obtain
water utilisation demand.
• Specific Objective 3: With water utilisation need, the specifications for
the raw water treatment works was achieved; Sharing of walls between
some tanks/basins, water conveyance by gravity: reduce construction
costs: minimize the pumping costs respectively
results to reduced water cost to the end users.
CONCLUSION AND RECOMMENDATION
• This design of a water treatment plant meets the general design criteria for water treatment plants. It meets its set objective catering for the rising water demands of Njoro Area as per the Sustainable Development Goal and contributes to Kenya Vision 2030 goals.
• Before implementation the following should be done: design of other civil works, a water distribution system, BOQ, A sewerage system design and comprehensive EIA.
