What is manhole rehabilitation?
Manhole rehabilitation involves repairing and restoring manholes to ensure they function properly. This can include fixing cracks, leaks, and structural damage to extend their lifespan and improve their performance.
Why is manhole rehabilitation important for municipalities?
Rehabilitating manholes is crucial for municipalities because it prevents groundwater infiltration and sewage exfiltration, which can lead to environmental contamination and increased treatment costs. It also helps avoid road collapses and other infrastructure problems.
What are the signs that a manhole needs rehabilitation?
Signs that a manhole needs rehabilitation include visible cracks, leaks, structural deterioration, unusual odors, and water infiltration. If you notice these issues, it's time to consider rehab.
How long does manhole rehabilitation typically take?
The duration of manhole rehabilitation varies based on the extent of damage, but typically, it can take anywhere from a few hours to a couple of days per manhole.
What are the benefits of choosing your company for manhole rehabilitation?
Choosing Rowland I&I Solutions ensures you get experienced professionals who use the latest techniques and materials. We offer reliable, cost-effective solutions that minimize disruptions and extend the life of your infrastructure.
What materials are used in manhole rehabilitation?
Rowland I&I Solutions uses materials such: 1. SewperCoat: This is a 100% Calcium Aluminate mortar solution. It is applied by spraying onto the inside walls of manholes to protect and rehabilitate the structure. SewperCoat creates a protective barrier that inhibits bacterial activity, reducing the formation of sulfuric acid, which can expedite the deterioration of manholes. It can be applied to moist surfaces and provides solid structural rehabilitation within hours​. 2. EpoxyTec Epoxy Coatings: These are used depending on the specifications provided by the infrastructure owner. Epoxy coatings offer robust protection against the corrosive properties of hydrogen sulfide gases present in sewage systems. 3. InflowShield Inserts: Made from 18-gauge 304 stainless steel, these inserts include a silicon gasket to seal out stormwater. InflowShield products are designed to prevent stormwater infiltration, which can lead to unnecessary treatment costs and system overloads during significant rain events. These materials are chosen by Rowland I&I Solutions for their durability, efficiency in sealing and protecting manholes, and their ability to extend the lifespan of the infrastructure without significant service disruptions.
What is CIPP and how does it work?
CIPP (Cured-In-Place Pipe) is a trenchless pipe repair method. We insert a resin-saturated liner into the damaged pipe, then cure it with UV light to form a new, strong pipe within the old one, without digging up the ground.
What are the advantages of using CIPP for pipe repair?
CIPP is less disruptive than traditional methods, requires no digging, and is quicker to complete. It also creates a seamless, durable pipe within the existing one, reducing future maintenance needs.
What types of pipes can be repaired using CIPP?
CIPP can repair a variety of pipes, including sewer, stormwater, and industrial pipes made from materials like clay, concrete, PVC, and cast iron.
How long does CIPP installation typically take?
The installation time for CIPP varies based on the pipe's length and condition but generally takes a few hours to a couple of days.
Are there any environmental benefits to using CIPP?
Yes, CIPP is environmentally friendly because it reduces the need for excavation, minimizes waste, and prevents leaks that can contaminate soil and groundwater.
What is CCTV inspection and why is it important for municipal infrastructure?
CCTV inspection uses a camera to visually inspect the interior of pipes. It's essential for identifying problems like blockages, cracks, and leaks, allowing for timely repairs and maintenance.
How often should CCTV inspections be performed?
CCTV inspections should be performed regularly, typically every 1-3 years, depending on the age and condition of the infrastructure.
What can CCTV inspections detect in underground pipes?
CCTV inspections can detect blockages, cracks, leaks, root intrusions, and other structural issues within pipes
What is the process for conducting a CCTV inspection?
We insert a camera operated crawler into the pipe, which records HD video footage. The footage is then analyzed by a NASSCO Certified professional who is able to identify any issues and determine the best repair methods as per NASSCO standard
Can CCTV inspection data be used for preventive maintenance planning?
Yes, the data from CCTV inspections is invaluable for preventive maintenance, helping to plan repairs before small issues become major problems. Also and in most cases the county for which the resident/business resides in requires a log of all inspections, issues and repair must be maintained for compliancy/regulation.
What are open cut repairs and when are they necessary?
Open cut repairs involve excavating the ground to access and repair or replace damaged pipes. They are necessary when pipes are severely damaged or when other methods, like CIPP, are not feasible
How do open cut repairs compare to other repair methods?
Open cut repairs are more disruptive and time-consuming than trenchless methods but are sometimes necessary for extensive damage or when pipes need to be completely replaced.
Are there any disruptions to traffic or utilities during open cut repairs?
Yes, open cut repairs can cause disruptions to traffic and utilities. We work to minimize these disruptions and ensure public safety throughout the repair process.
What safety measures are taken during open cut repairs?
We implement safety measures like proper signage, barriers, and traffic control to protect workers and the public. Our team follows strict safety protocols to prevent accidents and injuries and are properly trained by certified safetly professional on the lastest techniques and safety protocals.
Do you offer emergency open cut repair services?
Yes, we offer emergency open cut repair services to address urgent issues quickly and effectively, minimizing downtime and damage.
What is a lift station and why is its rehabilitation important?
A lift station pumps wastewater from lower to higher elevations, essential for proper sewage flow. Rehabilitation ensures it operates efficiently, preventing system failures and overflows.
What are the common issues that require lift station rehabilitation?
Common issues include pump failures, electrical problems, corrosion, and blockages. These issues can lead to inefficient operation and potential overflows.
How do you assess the condition of a lift station before rehabilitation?
We conduct a thorough inspection, including visual checks, performance testing, and electrical evaluations, to identify any problems and determine the best rehabilitation approach.
What are the steps involved in lift station rehabilitation?
Steps include inspecting and diagnosing issues, cleaning and repairing components, replacing faulty parts, and testing the system to ensure it's functioning correctly.
Can lift station rehabilitation improve energy efficiency?
Yes, rehabilitating a lift station can improve energy efficiency by replacing old, inefficient pumps and components with modern, energy-saving alternatives.
