NCS Fluid Systems crews get the job done!
Getting the job done: safe, right first time and as the team of top talent that NCS is known for!
NCS Fluid Handling Systems provides a wide variety of essential services to Energy, Industrial applications, and Municipal infrastructure support. These services range from dewatering, water treatment, water management, filtration, bypass services and professional engineering solution performed by “In house” engineers at the various NCS Branch offices across western Canada.
We thought maybe if we captured a truck loaded with equipment as well it would demonstrate what NCS Fluid Handling Systems does, then we realized that might be what others think when a picture of a loaded truck gets shared on social media but then we realized that’s not what NCS Fluid Handling Systems is known for nor does not does it reflect the trained technicians at NCS Fluid Systems do everyday, so we not only showed a picture of a loaded truck we showed a current project where NCS Fluid Handling Systems trained technicians are doing the work, performing the tasks safely and in cooperation with our “in house” professional engineers have come together to perform this sludge pumping and sanitary bypass project for our client so a regular maintenance and internal coating repair can be performed. Doing the work, creating the solutions, engineering the design, and putting in the time is what the NCS Fluid Handling Systems team is known for, not a picture of a loaded piece of equipment.
This job has it all going on, multiple flows being bypassed, sludge pumping, 100% redundancy, confined space entry, full monitoring, and a live operating site in a municipality in British Columbia.
When municipalities plan on upgrading existing sanitary system lines one thing to remember is you can’t just turn off the flow while working on rehabilitating an existing sewer system, but it can be diverted. Over the years this situation has create a huge challenge for these projects. How does the municipality continue to deliver services, or prevent closing roads and disrupting nearby communities and businesses while the contractor is performing rehab or replacement work?
Sanitary systems need to remain in operation.
When the decision is made to perform sewer rehabilitation it is typically to replace aging or insufficient pipelines. The solutions are that that the waste products must be diverted and a temporary system needs to be put in place. NCS Fluid Systems designers accomplish this by deploying pumps and temporary bypass piping and valves upstream from the sewer pipes that will be replaced and re-enter the sanitary system downstream of where the work is being performed. The size of the system is calculated based on peak flow which varies depending on the number of homes and businesses along this section of a line, the amount of waste material moved can exceed thousands of liters per minute.
NCS Fluid System designers have years of system design and experience and sizing the line is a critical step, since the amount of waste material required to be bypassed varies from time to time throughout the day the temporary system must accommodate this changing flow. Typically, the peak is calculated using flow meters and peak flow is usually early in the morning, and again in the evening when residents return home. This design calculation of peaks is crucial to the project success. If the flow is not calculated correctly and the system is undersized the pumps or piping may not be able to keep up and sewage spill may be the result, which leads to many problems for everyone.
Pump selection may also vary
NCS Fluid System designer and installation crews consider project specific situations such as the depth of the sewer system or distance of bypass, this quite often determines the size and type of pump(s) and ancillary valves, pipe and other equipment needed. For instance, when a sewer line is buried deeper than 7.5 Meters or approximately 25 feet, the designers may select a submersible pump to handle the added head pressure. Where as for systems not as deep a Above ground centrifugal pump with a suction hose lowered into the manhole may be selected.
Flow calculations are only a part of the overall operational considerations that NCS Fluid Systems designer review:
- Are there municipal noise ordinances?
- Road access, NCS offer engineered road crossing to accommodate traffic flow.
- 24-hour system monitoring by skilled technicians
- Equipment placement - Is signage and traffic control required,
- Environmentally sensitive areas may require seamless piping systems such as HDPE piping to be assembled reducing possibility of leaks.
In the market, today a sewer system upgrade project may be an open cut replacement or a trenchless lining technology rehabilitation but the one thing that won’t changes with any rehabilitation is the need for a properly designed bypass system the incorporates the right type, size of pumps and piping. doesn’t change with either of these methods is the need for the proper pumps and equipment.
Get the job done right first time, safely and on budget that’s what we care about at NCS Fluid Handling Systems.
