Example Pump Controls in InfoSewer and H2OMap Sewer
Five ways to control the pump by controls in InfoSewerH20Map Sewer. Here are a few examples and important features of the various InfoSewer Pump Controls. A pump in InfoSewerH20Map Sewer uses a Newton-Raphson iteration process for 50 iterations or until the successive … Read the rest
InfoSewerH20Map Sewer recognizes two different types of Controls. They are as follows:
· Initial Status – Initial status prescribes the initial setting for a pump InfoSewerH20Map Sewer Project. This control on the element may be over written by the Simple … Read the rest
Steady-state analysis and design of storm sewers is usually accomplished under worst (i.e., peak) runoff conditions to test transporting capacity of the network without causing major flooding or overflows. The Rational method is the most widely used technique for estimation of peak flow … Read the rest
In the past few years, advances in infrastructure management technology have been occurring at an accelerated pace. This technology is now being realized within the context of sanitary and storm sewer modeling. It has allowed sewer collection system modeling … Read the rest
Pumps in InfoSewer and H20Map Sewer
A pump is a link that imparts energy to a fluid thereby raising its hydraulic head. Pumps are needed in a gravity sewer system to prevent deep excavations, and are designed to lift the fluid to a desired level that produces gravity flow condition … Read the rest
InfoSewerH20Map Sewer provides unparalleled network analysis and simulation capabilities for performing a wide range of essential modeling tasks. WithInfoSewerH20Map Sewer, the entire sewer collection system or any selected sub-system may be analyzed under steady state and extended period simulations. Please note the stormwater … Read the rest

Manholes in InfoSewer and H2OMap Sewer
Manholes are points in the network where links join together and where loads enter the network. They are also placed at locations where pipe characteristics change (e.g., diameter and slope). The basic input data required for manholes is:
Rules for 
Routing in InfoSewer and H2OMap Sewer
1. Loading Manholes can take unlimited flow
2. Gravity Mains will take all of the flow from the Loading Manholes, but
3. d/D will be 1 and q/Q or q over Qfull will be much greater than 1
4. A Wet Well … Read the rest

Design in H2OMAP Sewer and InfoSewer
STEADY STATE DESIGN
A sanitary sewer collection system has basically two main functions: to convey the designed peak discharge and to transport solids so that deposits are kept to a minimum. It is imperative, therefore, that the sanitary sewer has adequate capacity for the … Read the rest
