Lift Station Management

Project Overview

A retail facility in Katy, Texas, had been experiencing recurring emergency service calls tied to the performance of its sanitary lift station. What initially appeared to be isolated events had developed into a repeat operational issue, indicating that the problem extended beyond routine maintenance or a one-time blockage. After responding to multiple emergency callouts, AQUALIS evaluated the system and identified the need for a corrective solution that addressed the source of the failures rather than their symptoms.  

The Challenge

Even with regular maintenance and inspection, this lift station was experiencing consistent clogging and backups. AQUALIS was called onsite for emergency services multiple times. With some minor investigation, it was determined the cause was the density of materials entering the station. The lift station was being impacted by solids and debris entering the sanitary sewer main and reaching the station without sufficient reduction. As those materials accumulated, they increased the likelihood of clogging, disrupted normal pump operation and added unnecessary stress to downstream equipment. When material builds up in the lift station because it cannot move throughout the system efficiently, multiple problems occur. Not only is the amount of material that can be processed reduced, but the pump station must work harder to move heavier or denser materials that it was intended. This is a common problem at high traffic sites as non-flushable materials enter the system.

Pumps under constant strain do not last as long and are more susceptible to failure. 

Although emergency service restored the system temporarily, the pattern of repeat failures made it clear that reactive maintenance alone would continue to drive downtime and service costs. AQUALIS recommended implementing an upstream device to break down materials before they reach the lift station. 

AQUALIS approached the issue as an infrastructure reliability problem rather than a simple maintenance concern. Correcting it required improvements at the point where solids were entering the system, along with installation methods that could be executed safely within an active commercial environment. For the project, AQUALIS provided excavation, utility access, grinder installation, electrical integration and full site restoration.

Site Access and Preparation

Because the new grinder system needed to be installed upstream of the lift station, the sanitary sewer main had to be accessed directly. Once the appropriate approvals were obtained, construction fencing was installed to establish a secure work zone, followed by removal of the existing concrete surface and excavation to the buried line. To reduce impact to business operations, the lift station remained active during the repair. Because of this, wet well conditions had to be controlled throughout the installation. A vacuum truck was used as needed to maintain workable levels and support safe access to the system.   

Installation of Wastewater System 

With the sanitary main exposed, stormwater professionals established the tie-in point for the new equipment and prepared the excavation to support the installation. A base layer of aggregate was placed to provide a stable foundation and a precast concrete manhole structure was installed to house the grinder assembly. The chosen grinder Muffin Monster unit was then integrated into the sanitary main within the new structure. 

Locating the grinder at this point in the system was critical. Rather than allowing debris and solids to pass unprocessed into the lift station, resulting in backups, the installation created a dedicated processing point for solids to be ground into smaller material before reaching pumps and related components. 

Controls Integration

The project also required the grinder system to function as part of the existing lift station infrastructure. To accomplish that, AQUALIS wired the unit into the existing control panel so its operation aligned with system demands and pump activity. A separate control panel for the Muffin Monster was also installed. This integration was essential to achieving reliable performance and ensuring the grinder operated as part of the facility’s overall wastewater system rather than as an isolated equipment addition. 

 

Restoration and Closeout 

The completed installation significantly improved the reliability of the facility’s sanitary lift station and reduced the conditions that had been driving repeat emergencies. By introducing solids reduction upstream of the lift station, the system gained additional protection against the debris load that had been contributing to clogs, interruptions and equipment strain. The result was more consistent operation, lower risk of future emergency callouts and better protection of downstream components, ultimately reducing operational expenses for the client. 

The project reflects AQUALIS’ ability to diagnose recurring wastewater issues at the system level and implement solutions that extend beyond short-term restoration. In this case, the problem was not a single failed component but a repeatable flow condition affecting lift station performance. Addressing that required technical judgment, experienced execution in an active wastewater environment and infrastructure improvements designed to support long-term operation. The result was a more dependable system and a practical path away from recurring reactive maintenance.
