Typical of any project dependant on the use of gravity consider all available options to secure the most suitable natural flow course. Our settled sewerage network (SSN) project in Tamale cognizant of this have taken land are properties measurement of the project area to identify contours showing high and low points as critical information needed to aid the design of the pipe network.
With the potential of the project to scale, we considered Geographic Information System (GIS) mapping (not part of the original project development plan) to develop a multi-purpose layer map of the area.
The inclusion of this (GIS) together with usual terrain evaluation for slops on the topography of the area will now provide us with adequate and reliable data to ensure that network gravitate to point of treatment.
