#DidYouKnow Inverts in manholes are used to provide a smooth transition for wastewater flow as it moves through the sewer system. Inverts are the lowest point inside a manhole where the sewer pipe meets the manhole structure. They play a crucial role in maintaining the efficiency and functionality of sewer systems by promoting smooth flow, preventing blockages, and facilitating maintenance activities. #redbrick #contractor #rehabilitation #wastewater #artwork #jobsite

What are Inlet Filter Inserts Inlet filters are point source filtration devices that treat stormwater at the individual inlet as opposed to end-of-pipe systems that typically have one treatment unit at the outfall. Detention/retention ponds and hydrodynamic separators are good examples of end-of-pipe, having only one area where all of the stormwater is brought to for treatment. Inlet-based treatment systems are always found inside the inlets in paved areas, and sometimes in grassy areas as well. The reason you typically won’t find these in grassy areas is that the grass will filter silt and sediment before it gets to these inlets. If the inlet is adjacent to a paved area treatment may be required, but this is at the discretion of the county during plan review, so not a decision we need to make. The drawings will show the location of the inlet filters. https://lnkd.in/gSJkHhjE #stormwater #civilengineering #stormwaterprofessionalsgroup #texas #detentionpond #propertymanagement

We’ve got more lids than your drawer full of Tupperware containers 🤣 Our lids are a little different though and definitely won't get misplaced. The 17-tonne pre-cast lid that’s been lowered onto the deep chamber at our Central Interceptor Hillsborough site won’t be any use to you, but for us it’s a big deal. The chamber that it’s now firmly covering diverts wastewater flows into the shaft. That chamber gives our team access to said shaft to do maintenance on the Central Interceptor tunnel that lies 30-metres underground. And, sticking with the lid theme, across town at our Avondale site, a concrete lid has been gently placed on top of the diversion chamber that redirects wastewater flows from a mini poo tunnel – we call it link sewer C – to the main Central Interceptor tunnel. The main tunnel that all the diversion chambers will connect to is slowly but surely being connected to the local 💩 network. Once that’s done and dusted, the massive tunnel will transport flows of wastewater to Māngere Wastewater Treatment Plant for processing. All this mahi will help reduce wet weather overflows into local waterways and onto beaches. You could say, we’re putting a lid on wet weather overflows 👍 Ghella Abergeldie Joint Venture (GAJV) #CentralInterceptor #infrastructure #construction #tunnelling #tunnels #tunneling #WaterIndustry #wastewater #team #teamwork #environment #NaturalEnvironment

This is called a mitered end drainage structure (MES) – providing better hydraulic results to water flow. Mitered ends can handle up to 10% more water and are much less likely to be plugged by debris. Mitered drainage end structures offer a more efficient and angled approach for stormwater discharge from pipe inlets. This design feature allows the flow of stormwater to transition more effectively as it exits the pipe, creating a more controlled and manageable discharge point. #mes #discharge #kcinow #stormwater #swppplife

Today was the start of installation for approximately 35 acres of geosynthetic clay liner, HDPE geomembrane, and geotextile for the Badlands Landfill P2S1 Liner Expansion project. Landfills are required to have liner systems to protect ground water from leachate. What is leachate? Trash tea essentially. The additional liner will extend the life of the Badlands Landfill from 3 to 4.8 years depending on various factors.

To facilitate the rodding of sewers, cleanouts are provided (oily and potentially oily sewer systems). Cleanouts are commonly used at the following locations: ·       At the Head of Sewers (if there is no catch basin or manhole already in place) ·       Changes in Direction(more than 45°) ·       Regular Intervals (maximum 30m) ·       Additional locations where rodding access may be necessary #gravitydrainagesystems #oilysewersystems #cleanouts #WWTP
