    Standpipe level indicators not reading accurate causing overflows

    When the pump turns off, - if the level stays at its faulty low level, and only drops gradually at whatever the consumption rate is, then the problem is NOT turbulence/velocity induced error. - if the level moves fairly rapidly from its faulty (low) level up to the overflow level, then the rest...

    Standpipe level indicators not reading accurate causing overflows

    Thanks for your informative post. I am going to answer what I can and I have an email into my controls subcontractor. Im at home and dont have the submittals on this computer. It sounds the pump runs off a VFD, so presumably the flow rate is the same for any given level. One would think the...

    Standpipe level indicators not reading accurate causing overflows

    Here are some rudimentary drawings showing the best I can illustrate the field conditions. http://files.engineering.com/getfile.aspx?folder=0706422a-ece9-4175-bd0d-f1eeaf320e1a&file=level_indicators.JPG

    Standpipe level indicators not reading accurate causing overflows

    We built a water plant next to an existing standpipe that has an overflow level of 100.75'. We have installed a level indicator at the base of the standpipe converting the pressure to elevation and transmitting the level to a newly installed SCADA system. The high service pumps to the...

    Disposal of Aluminium sulfate - Solid waste

    Are you sure it is hazardous in the sense you cant take it to a landfill under "special waste"?

    Power Supply Options

    I am surprised to see you guys have not yet mentioned traveling wave reactors. They seem to be the new hotness. If it turns out to be a reality, all of this energy crisis nonsense will be done in about 30-40 years. http://en.wikipedia.org/wiki/TerraPower,_LLC

    High Moisture Content Soil

    the soil is a 30-40 pi clayey / very fine silt. The wells were in place for about a month and the water is holding in the soil- it moves slowly like a glacier and has particles so fine it clogs the wells screens.

    High Moisture Content Soil

    I have a jobsite in which the water table is very high (9ft) The project required ecxcavating 38 feet deep and stockpiling the material onsite for 2 months. Even with dewatering wells, the water does not fall out of the soil so it stays vary saturated. The stockpiled material is also still...

    Short Body Check Valve

    Ductile Iron fittings (connecting to existing DI pipe)

    You can also use what is called a flange adapter or uni-Flange if you need to connect to a flanged fitting. If you are connecting to an MJ , you can use megalugs. For pipe to pipe connections, a dresser coupling like Stevewag suggests or a MJ couplier can be used.

    Reinf. Conc. Vault for Flowmeter

    you can do a precast vault and have the vault manufacturer "doghouse" the penetrations allowing you to lower it over the pipe, then filling the voids on the bottom of the pipe with grout. http://www.ctprecast.com/Products/images/48_doghouse.gif

    Sludge Thickener Bypass

    Good idea-- we have actually used synagro in the past and I didnt even think of them.

    Sludge Thickener Bypass

    We have a gravity sludge thickener that pulls solids from a transfer line between two aeration basins. The thickener needs to be worked on and has no redundancy, therefore needs to be bypassed. The sludge thickener currently pulls in approximately 300K GPD and sends off 100K GPD of thickened...

    1" PVC water line under creek

    If it is only ten ft wide, why cant you dig it with an excavator and bury it in ten minutes? At ten feet, you could stand on one side, dig a trench with a couple of swipes, lay the pipe in the trench with water and all and then bury it? Boring seems way too expensive for such a simple...

    Hydrostatic pressure test for ductile iron water pipeline

    you should flush it so particulates, rocks, debris dont act as a plug in whatever potential leak the pipe may have. Chances are low that the debris will actually plug it, but it makes it impossible if it is flushed.

    Problem w/ Steel Casing Bore &Gravity Sewer (NE1 up for a challenge?)

    Just to give those who were curious an update-- we potholed the casing in different spots and took shots. The casing is straight- horizontally and vertically-- We cut into the casing and it had filled up with water causing the pipe to float- when we cut it, the water flowed out and the pipe...
