The consequences of sewer system failure can be adverse to the environment. Therefore, it is important to make sure that the existing or planned pipe network can handle the incoming flow. Sewer collection network investigation should be done to identify and address issues related to sewer networks and management. 

We assist municipalities, utility companies, real estate companies, engineering firms and construction companies with sewer network capacity investigation. We follow specific standards and employ advanced methodologies to deliver accurate and reliable results.

BAHAPDE specializes in dimensioning pressure and gravity pipe systems.

We determine the pipe diameter based on parameters like discharge flow, pipe wall thickness, roughness, pipe slope, length & temperature, etc.

A low-pressure sewer system is a network of sealed pipes and pumps. Pump stations collect household sewage and pump them to sewer main.

Gravity sewer systems is a network of underground pipes that use gravity to move raw wastewater to a regional wastewater treatment plant. Properly designed and constructed gravity sewers can handle grit and solids in sanitary sewage and with self-cleaning velocity (at design flow), reducing the production of hydrogen sulfide and methane.

A sewer network is an infrastructure that fundamentally comprises of pipes and manholes and is characterized by a network layout and a hydraulic design. 

We design sewer network which generally includes a layout of sewer network with unique path for flow to reach outfall. A hydraulic design establishes the diameter for each pipe and can include provisions for future system expansion.

Inleak analysis is done in sewer pipes using flow measurement and rainfall data.

Comprehensive flow analysis with examination of flow rates, patterns and variations are performed. By correlating flow data with rainfall data, we identify abnormal flow patterns that indicate the presence of in-leak. This information enables clients to prioritize remediation efforts and allocate resources effectively.

We also provide recommendations and strategies for mitigating in-leak in sewer systems based on the findings of our analysis.

This service offers comprehensive analysis and calculation for sewer pump system.  We evaluate the performance of existing sewer pumps by analyzing pump curves, flow rates, head requirements, and energy consumption.

The ability of the system to handle peak flow conditions is assessed and solutions are proposed which may suggest pump capacity upgrades if necessary.

Drinking water network contains about 2% air and sewer water network about 5% air in the system. This air can behave differntly in different pressure variations.

An air valve is an important component in various fluid systems, particularly in water distribution and sewage systems. Its primary function is to automatically release air or gas trapped in the system, ensuring the efficient and uninterrupted flow of fluids. It also minimizes the potential for water hammer effects. Without air valve negative air pressure can occur in the system which may lead to damaging the pipes and fittings.

We offer accurate and reliable information to ensure proper air valve operation and effective system management.

Sewer collection network modelling allows engineers and wastewater management professionals to create a digital representation of the sewer system, including pipes, manholes, pumps, and other components. 

The process involves defining input data, such as flow rates, boundary conditions, and rainfall patterns, and simulating the hydraulic behavior of the sewer system over a given time period. Numerical algorithms are solved using industry standard software to solve the equations governing fluid flow and pressure distribution within the network. 

Sewer network modelling can provide valuable insights on flow velocities, pressure levels, self-cleaning, discharge and the risk of overflows or surcharges supporting effective planning, operation, and management of wastewater infrastructure.
