“We are so grateful for the filtration system which provides us with safe drinking water. The process sees the water pass through a chamber illuminated by UV light which kills close to 100% of the harmful elements.”

“Here’s our gang replacing the subterranean holding tank. It’s the first stop for water from the district supply. From the tank, water is pumped to higher tanks to be gravity fed to the dorms and kitchen.”

Vijaliwa Vingi Water Analysis Report

1.0 Introduction:

Assessment of the performance of the Water Purification Unit MAJI 350 which is located at Vijaliwa vingi Pre & Primary School in Mlandizi Kibaha District, Coast region, was conducted on 28th February 2022 by Staff from the Central Water Laboratory in the Department of Water Quality of The Ministry of Water.

2.0 Methodology:

Three water sample were collected from three locations, these are: (1) Raw water from the receiving tank before entering to purification unit, (2) treated water from purification unit and (3) treated water from reservoir tank for treated water.

Physical parameters were measured on-site and sample for bacteriological test were transported to the Central Water Laboratory and tested according to procedures stipulated in Standard Methods for the Examination of Water and Wastewater 23rd Edition.

3.0 Results:

The analytical results for physical and bacteriological quality are presented hereunder.
