Sewer bypass Vancouver Island NCS
I know you are all waiting for these posts each day with much anticipation and other than team meetings and air travel to and from Toronto (which was on time leaving and on time getting back) we only have lame excuses so we will make up for it today with 2 posts, just the second one will have to wait just a bit.
The crews in Victoria and Vancouver Island captured some very cool pictures of what the variety and beauty the Coast of BC has to offer during some of our recent and ongoing sewer bypass and creek diversion projects.
Sanitary Bypass or Sewer Bypass
NCS Fluid Handling Systems provides a wide variety of essential services to both Industrial applications and municipal.
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?
The solutions are that that the waste products must be diverted, and a temporary system needs to be put in place. NCS Fluid Systems engineering / 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 Handling System Engineering teams 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.
Flow calculations are only a part of the overall operational considerations that NCS Fluid Systems designer review:
- Are there municipal noise ordinances? – Solutions may include sound attenuated pumps or barriers
- Road access, NCS offer engineered road crossing to accommodate traffic flow.
- 24-hour system monitoring by skilled technicians or automated systems with remote monitoring
- Equipment placement - Is signage and traffic control required,
- Environmentally sensitive areas may require additional design consideration.
