A safe supply of potable water is the basic necessity of mankind in the industrialized
society, therefore water supply systems are the most important public utility. A
colossal amount of money is spent every year around the world for providing or upgrading
drinking water facilities. The major share of capital investment in a water supply
system goes to the water conveyance and water distribution network. Nearly 80% to
85% of the cost of a water supply project is used in the distribution system; therefore,
using rational methods for designing a water distribution system will result in
The water supply infrastructure varies in its complexity from a simple, rural town
gravity system to a computerized, remote-controlled, multisource system of a large
city; however, the aim and objective of all the water systems are to supply safe
water at the cheapest cost. These systems are designed based on least-cost and enhanced
In general, water distribution systems can be divided into four main components:
(1) water sources and intake works, (2) treatment works and storage, (3) transmission
mains, and (4) distribution network. The common sources for the untreated or raw
water are surface water sources such as rivers, lakes, springs, and man-made reservoirs.
The program DISNET is structured in such a way that it not only enables engineers
to design water supply systems in simplest and fastest way but also enables them
to design functionally efficient and least-cost systems. It is intended that students,
professional engineers, and researchers will benefit from the pipe network analysis
and design done by using DISNET. We hope, DISNET will turn out to be the most useful
tool for the water supply engineers as some of the fine aspects of pipe network
optimization are considered.
DISNET is available as stand alone software or in association with the software
HEADS Site (provided with various Site planning & Estimation facilities) to the
users for the convenience of the procurement.
The Output is produced as Text Report file and also as CAD Drawing file describing
Node wise description for Elevation and available Pressure Head. It also informs
about the Pipe number wise Diameter and Discharge for all the pipe in the network.
DISNET requires Total Station Survey data of the project site in 3D as Text or GEN
format or as CAD drawing. The step wise guide is given in Help menu to enable the
user to master the operations in a straight forward way by processing the Tutorial
data collected from real life project.
Node wise description for Elevation and available Pressure Head are Produced
Pipe number wise Diameter and Discharge for all the pipe in the network are Reported
DisNet in Drainage Planning
Surface drainage by open drains and subsurface drainage are probably the most comprehensively
studied subject in land drainage. The relationships between the variables and parameters
are well established. The remaining design problems are mostly due to the many other
interactions between the soil and the system affecting the choice of materials,
methods of installation etc.
Stream Hydrology is computed in details from Terrain Topography by transforming
Transverse marcator data to Universal Tranverse marcator (UTM) data, Referring to
WGS84 origin and directly downloaded from Shuttle Radar Topography Mission (SRTM)
without Topo maps. Discharge Location at Bridge is measured from farthest point
of the River for water discharge at the Bridge location. The environment is 3D CAD,
fully compatible to other CAD softwares.
Synthetic Unit Hydrograph is plotted by comparing sum of discharge for 1
hour interval of Time and volume of 1 cm direct Runoff.
