Abstract

In a fluid (liquid or gas) at rest, the isobars are horizontal surface. This fluid dynamic balance theorem provides adequate advance to tools and techniques for Water Quality Interpretation. We deal in this paper, with an effective way of exploiting the familiar communicating containers’ principle. That formally consists on providing water samples from desired depths of rivers, oceans, retention dams, etc. The prevailing limiting factor to achieve this feat is the length of our sampling pipes named Mbane Bathymetric Tube (MBT) designed for this purpose when rivers or retention dams are very deep. Providing drinking water to urban growing populations is a challenge that no government can escape. Therefore, improving the tools and techniques for water quality interpretation is an adequate advance for drinking water managerial techniques because this allows the recovery of contaminated water which abounds on the earth by acquiring appropriate wastewater treatment stations. The aim of the manuscript is to provide a brief theoretical description of our designed sampling equipment to allow everyone who is going to use it to solve in advance problems brought by Archimedes’ pressure force when experiencing the sampling pipes. Archimedes’ pressure force acts mainly when moving the sampling pipes to water lower levels and then opening its protective cover which allows the communication with the supply dam.

Highlights

  • The Yaoundé 2nd supply dam water, located in Nkolbisson-Minkoameyos village is exposed to demographic pressure

  • To reassure consumers of water supplied by Minkoameyos Lake, it is important to organize more often, campaigns on physicochemical and bacteriological analyzes of water samples from surface to desired depths of the lake

  • Our experience in Nkolbisson Lake is an adequate advance for drinking water managerial techniques because it allows an appropriate peer treatment of contaminated water which quality interpretation is irrefutable

Summary

Introduction

The Yaoundé 2nd supply dam water, located in Nkolbisson-Minkoameyos village is exposed to demographic pressure. The main interest of Minkoameyos’ Lake is that it is the largest and least exposed hitherto of well-known public Lakes that hosts Yaoundé city (e.g., Ngoa-Ekelle, Minkoameyos, Atemengue, Melen, Obili, Olezoa, Oyomabang, Emana, and Municipal Lake). Abandoned for years, this lake in the past supply water to Yaoundé populations and it is experiencing a resurgence of interest [1]-[5] provided by the rehabilitation project launched since August 2011 by CAMWATER Company. Our experience in Nkolbisson Lake is an adequate advance for drinking water managerial techniques because it allows an appropriate peer treatment of contaminated water which quality interpretation is irrefutable. Finding out more about the causes of the disease must be a prerequisite before looking for appropriate treatment of that disease (in our case: Finding out more about wastewater physicochemical and bacteriological interpretation is a great challenge before acquiring adequate treatment station)
