    Permanent Inlet Protection For Drop Inlet In A Gravel Parking Lot

    I will assume that the drop inlet is a grate at grade. I often recommend a debris screen placed right under the grate. see this diagram: https://res.cloudinary.com/engineering-com/image/upload/v1470606627/tips/Catchbasin_Model_CBS_-_w_Debris_Screen_Sizes_12_through_36_hgh80m.pdf Chris Eberly...

    Water line size

    Agree with Artisi & Dbill74. I'm from Texas, where "bigger is better". In the case of pipe sizes, the additional cost of upsizing the pipe size is often insignificant since the labor cost ia about the same to install 1" vs 2" pipe. It is common to use a day tank where your supply is limited. For...

    Water line size

    I have had good results using the Grundfos MQ Booster pump which has the flow/pressure control built into the pump. See this video for more information https://www.youtube.com/watch?v=6crT7RIjxh8 Chris Eberly, PE www.parkusa.com

    Water line size

    You may consider the line filling into a storage tank (non-pressurized, atmospheric tank) and then re-pressurize with a booster pump to serve the building. This method will guarantee you the desired flowrate & pressure. See this simple diagram: Chris Eberly, PE www.parkusa.com

    Poultry Processing Waste Water Treatment

    I agree. Dissolved air flotation (DAF) water clarification process can be used for the separation of solids, grease, and oils. The advantages of DAF systems are in wastewater sludge thickening and in the ability to treat a wide range of suspended solids (fats, oil, and grease) in water at a high...

    Fire Water Storage Tank - Overflow Protection (A requirement?)

    I have designed many of these type storage tanks for domestic and fire water service (called Break Tanks). The City of Houston requires these tanks for practically all multi-story buildings. The standard design includes an overflow for all compartments. The tank overflow discharges into an...

    Concentric vs. Eccentric Manhole Cones

    Correct. The flat surface allows for placement of a ladder or manhole steps. The ladder is recommended to be frp or stainless steel construction for corrosion resistance. Chris Eberly, PE www.parkusa.com

    hydro test with fresh water

    Is it possible that the tank is leaking through gaskets which might be incompatible with the fuel? Chris Eberly, PE www.parkusa.com

    Ultra-Low Flow Metering of Wastewater

    thread161-357912 I have an acid neutralization wastewater application where the city is requiring metering of the wastewater discharge prior to entering the city sewer. The amount of wastewater is about 200 gallons per day. This appears to be well below the minimum of all open channel flumes. I...

    Priming a Pump in Suction Lift Service

    You might consider a submersible pump system in lieu of a self-priming pump. I found this website online that may be of some help: http://parkusa.com/index.php/products/waste-water/lift-stations-2
