These lift stations are out of sight!
Sometimes the highest priority for a pump station isn't function or reliability -- it's invisibility. When you have valuable real estate and you want it to have an unbroken view, it's understandable that you might want your lift stations to be neither seen nor heard.
Lots of engineers have a gut instinct that a wet-pit submersible pump station with a below-ground valve vault will offer the most invisible option possible. But there's a way to hide a lift station even better than that.
You see, unless you go to some pretty extraordinary lengths, a submersible pump station is still going to have several features that show up above-ground: Power connections, a control panel, a pump hoist (or at least someplace to put it), and in many cases, a fence for safety. And you can't easily hide these things, since you'll almost always need some kind of access for a truck in case the pumps have to be pulled.
And that's not saying anything about provisions for backup power in case of an electrical outage.
We're here to tell you that not only is there a way to make a lift station even more invisible than a submersible, but also longer-lasting and easier to maintain. The answer is found in the Gorman-Rupp Reliasource below-ground station configuration, using self-priming Super T Series or Ultra V Series pumps.
These stations are available in two diameters: 7.5' and 10'. They come in completely self-contained fiberglass units that can be buried next to the wetwell. The enclosure comes with a water-tight access hatch and entrance tube, providing near-perfect invisibility to anyone passing by. The entrance tube includes an inlet and outlet for the safe and dependable exchange of air by the integral ventilation system (ensuring maximum operator safety). The rest of the station is kept completely out of view -- but also safely separated from the hazards of the wetwell.
Enhancing the safety of the below-ground station is the way it permits operators to conduct any required maintenance or service on the pumps without ever exposing themselves to the wetwell. The pumps use their suction-lift capacity to bring the water up through the suction line before discharging it to the force main. Thus the pumps stay wet on the inside but dry on the outside. And they are driven by ordinary TEFC, ODP, or XP motors powering the pump through a V-belt configuration. That means there's no depending on exotic motor types or cooling jackets, nor is there any need to pull the pumps for routine inspections.
In fact, virtually all maintenance, service, and repair can take place with the pumps and motors remaining safely in place inside the station. A pump could be completely rebuilt in place without ever removing the pipes or lifting the casing. Don't overlook the fact that a self-priming pump can shave 25' off the excavation required for a dry pit -- so even where a deep wet well is unavoidable, one of these pump stations could bring your operators (and all of their tools) 25 feet closer to the surface.
And these pumps last, too. External sight glasses make it easy to check on seal and bearing oil levels with just a glance, and external shimless adjustment means that the pumps can be maintained in peak efficiency without any operator having to encounter the liquid inside. The typical configuration for a Gorman-Rupp municipal self-priming pump will pass a 3" diameter spherical solid, and if the worst-case scenario comes about, the pump can be unclogged through the easy-access coverplate and put back into service in a matter of minutes, at a fraction of the time it takes to unclog a submersible (and none of the cost of calling a service truck).
All told, it's not unusual for these pumps to remain in service for decades at a time with little more than some routine inspections and the occasional oil change. And even when you're pumping the worst, you can rest assured that most of your pump is completely dry and the motor will never be submerged (plus, material upgrades to austempered ductile iron and high-grade stainless steel are available if you really need them).
Best of all, the whole package is factory-assembled and tested before shipment, so you can be confident in a quick installation and a dependable startup.
So if your first priority is to keep your lift station out of sight, the Gorman-Rupp below-ground station option is the best choice for a comprehensive solution that values operator safety, low visibility, and long-term reliability. Contact us for more information or for a look at the options.
Easier ammonia measurement
Iowa's revised water-quality standards are forcing some lagoon systems to face tougher limits for ammonia than they're used to observing. If you're in that boat, consider ATI's Q46N dissolved-ammonia monitor, which permits you to monitor ammonia with a simple, on-line monitor. The system is simple and compact, and it costs a lot less than competitive instruments. Contact us for specs, pricing, and options for a trial installation.
A free tool for budget savings
It's becoming clear that many municipal budgets are going to be under stress in the coming year, as the pandemic raises many costs while it also cuts into revenues. It's not always easy for water and wastewater utilities to cut operating expenses while remaining in compliance, but nobody wants to cut salaries at a time like this, either. We'd like to offer access to a tool that might help.
Thanks to our new relationship representing Hoffman and Lamson blowers to wastewater customers in Iowa, Nebraska, and South Dakota, we can offer you access to audits of energy use that can uncover major aeration blower power savings and help with cost reductions. Typical wastewater sites can experience an energy savings of 20% or more by taking action based on these audits. (Find out what's involved.)
In addition, incentives can help fund recommendations from our audit. These audits are a $3,995 value, but for a limited time, we can have those charges waived and offer audits to qualified plants for free. We would be happy to present this to you and discuss further, so please let us know if you are interested.
We realize that due to Covid-19, most site visits are restricted. We can provide you with a program overview and all of the information you require to make an informed decision on the value to your plant via a video presentation over Skype, Zoom, or Teams at your convenience. Then, when the time is right for travel, we can get your energy audit on the calendar.
Our team wishes you good health and safety at this time. Please let us know anytime if we can be of service to you.
A simple diversion
For those applications where simple flow diversion is needed in an open channel, stop gates are an economical measure for getting the job done. We have supplied Golden Harvest stop gates and frames on projects serving in applications like headworks (where they can be used to isolate a channel containing a mechanical bar screen or a grit trap, for example) and disinfection systems (where a UV disinfection channel might need to be taken out of service for lamp replacement), but also in flood-control and storm diversion applications as well. Aluminum and stainless steel construction are both available. Contact us for more information on stop gates anytime.
Biological nutrient removal (BNR) aided by baffles
For those operators and engineers looking to improve biological nutrient reduction by separating aerobic from anoxic zones, we would like to highlight the effectiveness of creating that separation by using tank baffles from Environetics. They're literally flexible (in the sense that they're mostly composed of geomembranes), of course, but they're also installation-flexible -- they can be retrofitted into existing concrete structures or moved, altered, and adapted to suit changes in condition. The pricing is highly economical, the materials are durable and long-lasting, and the installation process is much easier than for any other type of control structure. Contact us for more information.
Virus detection at the wastewater treatment plant
A story in Water and Wastes Digest says that a Dutch city of 150,000 found evidence of coronavirus in its wastewater before any cases had been otherwise detected in the city, just a week after the virus was first detected in the Netherlands.
The good news: This suggests that wastewater-level detection could provide useful surveillance to public-health experts as an accessory to the test, isolate, and trace protocols being discussed as the best means of dealing with the virus until vaccines are available. More information gathered at the community level can help identify hotspots that might be experiencing asymptomatic spread.
The bad news: It still isn't clear whether the virus can actually be transmitted in wastewater, either in the liquid flow or otherwise. Drinking water remains safe, but we also need to show concern for the public-works employees responsible for the collection and treatment of wastewater. They are invisible -- but essential -- front-line workers protecting public health, and they need adequate protection, too!
We have always believed that one of the most important ways to protect workers in the wastewater sector is to keep them in safe, above-ground locations wherever possible -- where fresh air and limited exposure to sewage can preserve their health. With the uncertainty surrounding the transmission of COVID-19, that's suddenly more true than ever. See our presentation "Revenge of the Mole People" for a list of 25 related reasons why it's important to keep wastewater workers above-ground (or as close to the surface) as possible, and 10 ways that lift stations can be designed to maximize that potential to stay high, safe, and dry.
