A Handy Tool For Wet Well Maintenance: Cutting Through The FOG A Handy Tool For Wet Well Maintenance: Cutting Through The FOG

Blame our fast food diets or restaurants’ negligence for what’s going down the drain. Whatever the cause, fats, oil, and grease (FOG) accumulation has become a pervasive problem for wastewater treat­ment plant collection systems.

  • Building A Better Plan To Cope With Major Water Leaks

    It is perhaps a water utility manager’s greatest fear — a rupture in a major water distribution line. Although such occurrences are sometimes unavoidable, proper planning and preparation can go a long way toward easing the sting of such a major event. But where do you start? Here are some guidelines that can prevent the next such occurrence from becoming a 6 o’clock news nightmare.

  • What To Do When Your Water System Is Under Water

    Much has been made about how climate change can limit the source water available to pump inside distribution pipelines. On the other hand, however, what can be done when climate change delivers too much water — in the form of flooding rains — on the outside of those pipelines? As is true for so many other water infrastructure scenarios, being prepared is half the battle. Here are some suggestions for weathering the storm.

  • Managing Data To Maximize Asset Maintenance Efficiency

    Although an ounce of prevention is worth a pound of cure, all the money spent on regularly scheduled maintenance can add up to a ton of waste — and still result in unplanned downtime — if asset managers can’t reasonably differentiate between which equipment truly needs attention and which doesn’t. Fortunately, data-centric analytics derived from physical performance in real time can make that distinction. Here’s how.

  • Using Special Repair Fittings To Tame Tough Pipeline Problems

    For most water utilities, maintaining existing infrastructure — whether planned or in response to emergencies — is a large part of physical plant costs. Being prepared to respond is half the battle. Here are several guidelines and options to consider for maintaining the most cost-efficient solutions to everyday pipeline problems. As with most good plans, they start with proper organization.

  • Finding A Perfect Fit For Mix-And-Match Piping

    Today’s water/wastewater piping options offer numerous advantages in terms of cost, performance, and anticipated service life. Unfortunately, utilities must still deal with what’s already in the ground — steel, cast iron, ductile iron, asbestos cement, plastic, concrete, and even wood. Here are guidelines on making transitions between old and new pipes of varying sizes and materials as smooth as possible.

  • Clamping Down On Bell-Joint Leaks

    When one considers all the bell joints in a water distribution or wastewater collection system — caulk-joint or rubber-joint — and all the stresses to which they are subjected, it is a wonder there are not more leaks. Fortunately, bell-joint-leak clamps provide a reliable and relatively easy-to-install solution — if they are properly specified and installed. Here are some key points to consider when trying to remedy bell-joint leaks.

  • Put A 'Stop' To Water-Main-Repair Shutdowns And Boil-Water Notices

    For most water or wastewater system operators, engineers, and repair crews, the only thing worse than facing a 24”-main emergency repair is facing an even larger one. To those who have never performed an emergency line stop and bypass, the idea of completing repairs with no service outage, no long-term shutdown, and no ‘boil water’ notice is almost beyond belief. To those who have, it’s a sigh of relief.

  • Mapping Assets For Resilience And Response In Emergencies

    Among utilities concerned about resilience and response in natural disasters or other emergencies, precise asset inventory and mapping are high priorities. In truth, there is value in having the same information for everyday purposes as well. For anyone who has ever had a problem locating or tracking key water or wastewater system assets, here are several good reasons and ways to avoid a last-minute scramble.

  • Asset Monitoring: Are You Getting Your Money’s Worth?

    Mapping the assets of a water treatment, water distribution, or wastewater collection and treatment system is just the means to an end. Maximizing value from that effort requires systematic planning and a healthy curiosity for looking into patterns of activity. Here are some considerations for turning raw asset data into more valuable benchmarks for better decision-making across multiple aspects of water operations.

  • 12 Installation Tips For Challenging Pipeline Repairs

    Having to repair old, worn, broken, or leaking pipes is bad enough. Having to revisit the repair location a second time to refurbish the original fix is doubly frustrating. Here are some guidelines for getting the best results from pipeline repair efforts and enhancing the durability of the repair effort to match the anticipated service life of the pipeline itself.

flood_iStock-471000383 How To Predict And Prevent CSOs And SSOs

Combined and sanitary sewer overflows are natural hazards for wastewater collection systems. Without a comprehensive solution to monitor troublesome conditions, overflows can be triggered with little warning and lead to expensive and embarrassing situations. Fortunately, versatile analytical systems that capitalize on existing wastewater collection infrastructure hold promise for avoiding such negative impacts.

Wastewater Collection System

Orenco Sewer™ (effluent-only sewer) is a cost-effective, environmentally sound wastewater collection system. With an Orenco Sewer, raw sewage flows from a house or business to a watertight underground tank. Only the filtered liquid portion is discharged (by either pump or gravity) to shallow, small-diameter collection lines that follow the contour of the land. Solids remain in the underground tank for passive, natural treatment and only need to be pumped every 10 to 12 years (depending on the number of residents and the tank volume).

Orenco Sewers take significantly less time to install than conventional sewers. And in an Orenco Sewer, material and excavation costs are reduced because the inexpensive collection lines are shallowly buried just below the frost line. Because only liquid is being pumped, system designers don’t need to worry about minimum velocities and associated grades. This simpler installation process causes less disruption to communities and allows businesses to operate normally during construction.

Mueller Co. recently announced a new H-306HP fabricated steel tapping sleeve. Designed for hot tapping ductile iron pipe and thick-wall C900 plastic pipe, the H-306HP is made from A36 fabricated steel and meets the requirements of AWWA C223. It features an integral bolt flange, Rilsan nylon coating, working pressures up to 300psi, and is available sizes from 4”-16”. The H-306HP is an economical tapping sleeve ideally suited for use with Mueller® CL-12, C1-36, and Mega-Lite drilling machines in less corrosive soil environments.

The Reliant Water Technologies SCOUT Hydro Profiling System is the answer to obtaining clear and concise shallow water survey data quickly and inexpensively. By not only providing a visual hydrographic ‘picture’ of everything underwater, in any shallow body of water, the SCOUT also provides the volume of sludge in the water body (as well as the volume of free water). The ‘picture’ provided is color enhanced in order to provide clear, definitive delineation of variable depths of sludge, or debris, and includes multi-point water depth over-lays.

The Wet Well Wizard is the only ‘one-size-fits-all’ wet well aeration system that has no moving parts, is completely non-corrosive, is simple to install, and utilizes no electricity underwater. It can be installed in 30 minutes and requires almost no maintenance.

SEWERS AND SEWER LINE MAINTENANCE PODCASTS

Coping with service or repairs to aging pipeline infrastructure without disrupting customers is always a challenge. Chris Vazzana of Hydra-Stop has a better idea that includes the use of insertion valves, which enable water utilities to install a permanent valve into a live water main without ever shutting down the line. His discussion with the Water Talk moderators at WEFTEC 2019 details how the initial perception of insertion valves as a temporary measure is no longer true, and how these time-saving devices are now permanent assets that have passed AWWA testing, including burst testing and 500-cycle testing. Chris also describes the company’s newest 24” insertion valve, with an anecdote about saving a utility and 10,000 of its customers from a disruptive service shutdown.

There’s a new pipe joint in town. It’s the ALPHA restraint joint system launched recently by AMERICAN at WEFTEC 2016. According to Derek Scott, Marketing and Technical Manager with AMERICAN Flow Control, the new joint is easy to install with one stainless steel bolt at the top compared to the 8-bolts-on-each-end, traditional mechanical joint.

Susan Moisio, conveyance and storage leader with CH2M, sheds light on the conditions and obstacles facing municipalities as they struggle with stormwater management.

In this age of data acquisition, there is no corner on Earth that can’t be measured. In the water industry, that means plunging the deepest depths of our sewer systems.
