When planning for a commercial establishment’s success, an often-overlooked factor is its wastewater pumping system. If you’ve ever experienced a backed-up drain, you know the bad impression it gives customers while also leading to lost revenue, increased labor costs, and health and safety issues. The solution is selecting the right pump to ensure you’re equipped to handle your customer or tenant volume, as well as the solids that find their way into the system. Selecting proper solids handling pumps for your building’s wastewater requires considering the following factors.
What Solids Are You Pumping?
The first factor is knowing what items find their way into the drain. Let’s be honest, people in a commercial setting simply don’t care very much about what they flush down the toilet. You shouldn’t be surprised to find towels, rags, used diapers, and all sorts of other heavy solids in your wastewater stream. Inferior pumps can’t handle these more difficult solids and tend to clog.
Flushable wipes and paper towels are prime examples of items that may cause your pump to clog. This was the case for the Pomona Valley Hospital Medical Center. Wipes and rags were clogging their sewage ejection pumps, increasing pump replacement costs. Labor costs also increased as the hospital brought in extra maintenance staff to clear the clogs and replace the pumps. After switching to BJM’s SK shredder pumps constructed to handle the wipes and rags, the hospital hasn’t had any pump issues in 15 months, saving them time and money.
Another factor to consider is chemicals or corrosive materials that might be in the liquid. Especially in medical settings, you may have to dispose of corrosive lab waste. In these situations, stainless steel pumps are your best bet. Stainless steel resists corrosion better than cast iron pumps. Another of our customers is a children’s medical center that uses two wastewater sump pits. They use one for lab waste with stainless-steel shredder pumps and the other pump is for “normal” sewage and requires a shredder pump to handle wipes and paper towels.
Sizing Your Solids Handling Pump
After determining the right pump, you need to calculate the pump size needed to accommodate a large number of people. The piping and flow rate you need for your system varies. Luckily, most pump manufacturers and distributors can help you. The example chart below can also serve as a starting point for your pump sizing calculations.
Peak periods, even short ones, are also an important factor in selecting the right pump. During a restaurant’s dinner rush, it’s not practical for staff to stop and address backed drains and/or sewer systems. Stadiums and arenas are extreme examples of needing to handle thousands of people for a short period of time. BJM was able to help Coors Field handle large amounts of trash and debris in its storm sewer system. Once again, BJM’s SK shredder pumps proved to be the right solution. The pumps are reliable in handling the solids that find their way into the system while being durable for a long service life.
