Abstract
Sustainable facility design has been established as one of the most important practices for achieving
sustainability. Efforts to enhance the progress on access to drinking water, sanitation and hygiene in
institution’s environments, attain 17 United Nations' Sustainable Development Goals, environmental
and cost performances of a product require innovative design. This innovative facility design requires
new design concepts and engineering specifications. In this paper, pipe network analysis of Elizade
University (EU), Ilara-Mokin was conducted as a way to attain a sustainable product. The population
of the institution between 2011 and 2018 was collected and projected to 2026 using the geometrical
progression technic. Water demand at each of the nodes was computed using standard methods. The
network was drawn and analysed using EPANET software. The study revealed that the pipeline was
open loops, a mixture of both surface and underground layouts. It has an overhead tank, 43 pipes of
two diameters (50 mm and 150 mm) and 44 nodes. 50 mm diameter pipes accounted for 54.51 % and
150 mm accounted for 45.49%. The water demands at the nodes were between 30l/s and 480l/s, flows
in the pipes were from 20 l/s to 3545l/s, and the velocity of flow in the pipe was in the range of 1.13
m/s to 1805 m/s and the friction factor of these pipes ranged between 0.012 and 0.016. Analysis of
the Variance of the effects of the diameters on the outputs of the analysis revealed that the diameter
of the pipe has an effect on the flow or discharge and the velocity of flow or discharge in the pipe,
and the friction factor of these pipes, but not a significant a factor at 95 % confidence level (F1,10=
0.034; p = 0.858). It was concluded that the pipeline and pipe layout at the EU is mainly open loops,
consisting of 50 millimetres and 150 millimetres diameter pipes and the size of the pipe (diameter) is
a function of the flow rate, the velocity of flow and the friction factor through it.
