Sewer Bypass
Force main rupture? Broken gravity line? Lift station malfunction? Re-lining existing pipelines? Lift station upgrade?
The existing infrastructure (such as sewer line, pump stations, manufacturing plants) in major cities is getting old. To maintain and upgrade the existing infrastructure construction companies require a sewer bypass, which requires rental pumps and generators. Typically sewer bypass pumping will occur because of new construction, lift station repair, re-line existing pipelines, lift station malfunctioning, broken gravity line, force main rupture, tie-ins or a combination of these factors. Almost all sewage bypass work can be handled by NCS Fluid Systems. Sewage bypass requirements must be well understood before selection and design of the pumping equipment. This includes flows (min and max), TDH (total dynamic head), suction lift, NPSH (Net Positive Suction Head Required and Available).
NCS Fluid Handling Systems offers sewer bypass pumps from 4-inch to 12-inch diesel driven pumps available for sale and rent. Our engineering team will assist you in sizing and selecting the right pump for your application. Sizing the right pump is the key to achieve a stable sewage bypass and NCS Fluid Handling Systems huge inventory will make sure the sewer bypass pump is available for your project when required. In some sewer bypass pumping applications where there is high suction lift and where instant priming is required we recommend electric submersible pumps.
NCS Fluid Handling Systems has the complete suite of sewer bypass equipment including such items as diesel or electric driven dri-prime pumps, electric trash submersibles, hydraulic submersibles and diaphragm pumps. In addition remote monitoring, automatic start-stop, fuel consumption monitoring and trained HDPE fusion technicians. We are a one-stop shop for sewer bypass pumps and accessories such as road ramps, check valves, gate valves, hoses, steel and aluminum piping, HDPE piping and drip trays.
NCS Fluid Handling Systems sewer bypass skilled team has access to the most extensive inventory of electric sewage submersible pumps and associated submersible power cables. From low volume to high volume and low head to high head electric submersible pumps are your solution of choice. If the suction lift is too much and you need to work in an explosion- proof environment, then hydraulic submersible pumps are the key to your problem. We have hydraulic submersible pumps and power packs.
Hose and fittings are critical to the success of a sewer bypass. NCS Fluid Handling Systems sewer bypass team has a large stock of hose and fittings including lay flat hose, cargo hose, composite hose and suction hose. Our sewer bypass design team will design and fabricate a wide variety of equipment. Manifolds, pump skids, hose reels, special fittings and a wide variety of other equipment can be made to your specifications in a cost-effective fashion.
Sewer Bypass when you need it you need the team at NCS Fluid Handling Systems, because when it happens you need the responsive experts so it doesn't keep happening!
Sewer Bypass
Sewer Bypass or Sanitary Bypass
NCS Fluid Handling Systems provides a wide variety of essential services to Construction, Industrial applications and municipal.
When municipalities plan on upgrading existing sanitary or sewer system pipelines 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 bypassed and 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?
Sewer systems still need to be used.
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 sewer 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.
Design Considers
NCS Fluid System sewer bypass 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 sewer bypass 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.
Sewer Bypass Pump selection also varies
NCS Fluid System sewer bypass designers 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 trench-less lining technology rehabilitation but the one thing that won’t change with any rehabilitation project is the need for a properly designed sewer bypass system that incorporates all the right type & size of pumps as well as related piping.
