    Single Phase to 3 Phase efficiency

    Oh don't you all worry, there's good reason why I'm a civil engineer and have nothing to do with electrical!! He has been talking to an electrical guy who I believe works for a company doing the electrical engineering for all their plants (concrete and some related industrial). (There's a...

    Single Phase to 3 Phase efficiency

    Seven figures to extend it and it would be my client footing the bill. It's a long ways off. The sewage pump isn't huge, 3-4 HP maybe, but he said their efficiency will be at about 40%. I think the same pump with 3-phase would be no better than 70%. I'm waiting to hear sizes for the...

    Single Phase to 3 Phase efficiency

    I have a client interested in constructing a septage treatment facility that would include dewatering presses and pumping resultant liquid component about 180 feet (vertical head) up a hill to some leaching fields. He has a great property for it except 3-phase does not come to his property, and...

    $12,500 fine possible-placing culvert w/o a permit

    OK, I read it. Doesn't really change how I feel. I think (uh-oh, here I go..) if the Millers had been able to show clearly the culverts pre-dated the law or even if it looked as such to the DNR then it never would have gone to court. Just my opinion though. But I do agree the OP would do...

    $12,500 fine possible-placing culvert w/o a permit

    ..."They have you on the "maintain". It will not matter when it was built."... Not a chance. I don't live in WI, don't know a single law in WI. But if what you say is true then that puts every single driveway, private road, commercial/industrial site etc. that has a stream crossing built...

    Fire Pond - No Water

    I designed a fire pond that got built a couple years ago. During construction the contractor uncovered some fractured ledge that he believes is slowly draining the pond. He believes this is the one area that's draining as the water level was rising until he dredged out this particular area and...

    Handrails and Grade Differential

    Sorry, I have to disagree. I don't believe a single one of those applies to a driveway.

    stormwater - one word, or two?

    I just read Drew08's post and the two Google ad's below it. One for "Catch Basin Cleaning", the other for "Stormwater Drainage". So the beat goes on...

    SWMM "Time of Concentration"

    I've never used SWMM so I don't know if it's the primary software typically used for this application (I also haven't modeled such a large urban watershed, only rural). But since time of concentration is such a critical component of the various modeling programs I've used over the years, have...

    Precast segmental retaining wall under water

    Is this a residential pond? Or perhaps a retention pond for a development? Fire pond? The blocks really won't function altogether differently than large rip-rap, but if they're not connected together internally they'll be subject to movement. Small ponds in my neck of the New England woods...

    Handrails and Grade Differential

    Does HOA = Homeowners Association? If so then perhaps there is something in the Association Covenants requiring a handrail. But more basic, I assume the HOA concern is for pedestrian traffic as a handrail won't do too much for a vehicle (sorry to state the obvious..). How long is the driveway...

    Agricultural Runoff Treatment System?

    Have you consulted with your County Conservation District? They have access to all the latest agricultural standards and specifications from USDA. Who knows, maybe there's some grant money available to help out? The Farm Bill has programs to help farmers out, usually cost-share programs but...

    stormwater - one word, or two?

    storm (descriptive) water (noun) = two words red (descriptive) dog (noun) = two words That said, I always type it out as one word and I see it most often used as one word.

    Residential Septic System Cost

    A three bedroom house in the northeast, except Maine - new system including design/permitting costs - $22,000 would not be wholly unusual when dealing with the typical hardpan soil. Especially if a pump is required. Somewhere on the higher side of average, but not unusual. For soils with fast...
