1.0 Introduction
Josiah Girls High School is a Secondary School in the Kagera, region of Tanzania which is in the North-West corner of the country. Josiah Girls High School is in Bukoba city, about 8 Kilometers away from the city, Bukoba. The school has as estimated population of 600 people although during assessment the total population was estimated more than 500 people. The existing water supply system is from BUWASA, where water pipe is directly connected to a concrete storage tank constructed by BUWASA, the tank is a main storage tank to distribute water in the whole school with a capacity of approximately 20m3. Water from BUWASA is enough to fill the two existing storage tank which are raised tank with a capacity of 10m3 each one and a total of 20m3, but the tank storage is insufficient to cover the demand of the population in peak hours (when all students are out washing and cleaning). This results water shortage in few hours after usage due to high water demand from the estimated 600 students, therefore most of times student in the dormitories lack water for their usage.
The school board decides to find another solution which was to drill a borehole with an AC Submersible Pump as a backup for the BUWASA water source and also to increase water supply in the school for the students and staffs. But there is another problem observed during usage of this newly borehole as it dries up faster estimated two hours which is because of a over design of the pump compared to the borehole yield capacity or pump set was not correct as it was set at the Static Water Level therefore during Draw down water level changes down to the Suction point (inlet of the pump). Because the problem still continues the school board decided to find another permanent solution using a Rain Water Harvest Project 1 system in one of the Cafeteria building constructing a big estimated 100-200m3 underground tank. But after some few years it was suggested the tank is having unseen leakages on its walls, therefore contributes to water loss and the supply of its water was not sustainable.
Due to water supply problem at the school, Josiah Girls High School consulted our team for site visit and conduct a technical assessment effectively to establish proper Rain Water Harvest Project 2 system which will include proper water collection from all buildings and construct enough water storage tanks which will be used to harvest and supply enough water to the distribution system facing the community daily demand and future population to come.

a. General Objective
Promoting friendly learning environment by ensuring proper sanitation and hygiene facilities with adequate water supply by harvesting rain water at Josiah Girls Secondary School by 2021.
b. Specific objectives
c. Project Activities
i. To conduct community/school water need assessment
a. Community/school visit
b. Meeting: interview and focused group discussion with students and staff
ii. Design of the technical solution
iii. Project Implementation
iv. Project Commissioning
d. Project activity description
i. Community/school water need assessment
A sample of 10 students was selected representing all classes in school. Interviews and focused group discussion were the methods used for data collection. The community/school water need was assessed and identified with the associated challenges as listed below;
The source:
Steep slopes, mountainous, long grasses and bushes hence insecurity to students.
Water is contaminated since it is collected from a shared source being used for washing motorbikes and for cattle drink each afternoon.
P. O. Box 791 - Bukoba
Email:rcbukoba@gmail.com
School routine:
Interruption to school timetable for time spent on search for water this far distant source.
Poor reputation of school on this shortage hence affects performance of students.
Students' wellbeing:
It is a tiresome routine hence leads to psychological problems to students and with mind upset during classes.
Poor concentration of students in classes due to water shortages and with the schedules for the walk for water in this distant and unsecured place.
Menstrual Hygiene Management:
Poor hygiene management during menstrual periods due to shortage of water.
Psychological torments during menstrual period with inadequate water supply for hygiene management.
ii. Design of the Technical Solution
After a proper observation and technical assessment done by our team we carry our Engineering design corresponding to the requirement and observation. The design will include the following:
a. Design of the Rain Water Harvest
b. Design of the Water Storage Tank
c. Design of the Supply System i.e. AC Water Pump, Piping system, etc.
d. Design of the Distribution System i.e. Piping system, Gravity flow design, etc.
iii. Project Implementation
After the detailed design of the Rain Water Harvest System in the school compound our team will carry out the project in execution where will includes the followings:

a. Construction of the Water Storage Tank
b. Installation of the Rain Water Harvest System
c. Installation and Repairs of Piping System
d. Installation of Water Pump
e. Construction of Borehole Chamber
f. Operator training
iv. Project Commissioning
After the completion of the Rain Water Harvest Project activities, our team will submit the project to the school board and donors/funders. Before commissioning of the project to our client the following activities will be done that include:
1) Post installation checklist together with the school administration, the school technical team and the Rotary International.
2) Project delivery to the school.
3) The signing of the project commissioning agreement between parties.
e. Technical Aspect
Sammy Energy Company Ltd has been in contact with Rotary Club concerning the water problem at Josiah Girls High School in Bukoba. Challenges that the school faces include shortage of water mainly based on unrepaired leaks from existing water storage tank, unreliable water supply from Bukoba Water and Sanitation Authority (BUWASA) and water yield problem from the source yet without distribution infrastructures from the source to the school.
Aim of the assessment
The aim was to assess and design the construction of the rain water harvest system for the school which will solve the water shortage in the school buildings for student, teachers and other staffs usage daily through our the year. Other objectives will be repairs of the leakages on the underground water storage tank and piping system for sustainability water storage and supply for the school usage.

Data Collection
Our survey was done by using Simple hand held GPS to obtain coordinates and ground elevations of different points and buildings at compound.
Documents from the office (number of the buildings, dimensions of the buildings, type of the roofing's and materials)
Expected output
This coordinates and elevations will help us in choosing important points with good gradient to construct gravity rain water harvest storage tanks.
Helps to propose the pipeline routes that receive water from the Gutters.
Gives clear satellite pictures, distances apart and ground dimensions between the buildings that acts as our catchments areas of rain water.
Documents help to calculate the catchment area.
Rain water potential.
And rain water endowments.
Develop detailed design and project plan for the water project
Implement solar powered pumping system
