Operator Maintenance for Evans Water Treatment System

At Evans Equipment, we specialize in designing customized systems tailored to fit your specific business requirements. From initial concept to final implementation, our team manages every aspect, including construction, permitting, and ongoing scheduled maintenance. We understand that maintaining a reliable system goes beyond routine checkups and minor repairs. To ensure the operation and maintenance of wastewater collection systems is done efficiently and effectively, here’s our recommended operator maintenance checklist to do daily and weekly. 

Daily Maintenance

Daily maintenance might feel overwhelming, but it’s essential to maintain peak machine performance. Here are the daily tasks required to keep your system running smoothly.

Inspect the entire system 

The first step for daily maintenance is to inspect the entire system. During your inspection, it is essential to check for any wear and tear to the unit or leaks in the plumbing and hoses. You must follow various routine maintenance tasks for your system to maintain high efficiency. 

Your routine maintenance activities should incorporate different parts of your equipment, such as water level and control panel, electrical functions, and level of solids. 

Water Level and Control Panel

The next step is to check the water level in the Processed Water tank. Also, check the control panel to ensure the red “Low Water Level” light is not on. If you find the low water level red light is on, you need to check the pump function. If the pumps function properly, add water to the system as needed until the red light turns off. 

Electrical Functions

Regular inspections of your system’s electrical components are one of the most important parts of any maintenance process. You need to check to ensure that all electrical components are functioning properly. Also, visually inspect the control switches and lights on the control panel to ensure the system is running.

Level of the Solids

Look at the level of solids that enter the trench drain periodically. We recommend cleaning the trench drain twice a week using the sludge sucker. If washing a piece of equipment yields heavy solids, you need to clean the trench using a small excavator or shovel. Transfer any solids that you remove to the drying pad.

Weekly Maintenance 

Performing weekly maintenance ensures that your equipment remains in top condition, minimizing downtime and maximizing efficiency throughout your operations. The following are a few things to observe weekly. 


The first step to performing routine weekly maintenance on your wastewater system is to clean the Y-strainer in the sump pump. Keeping the Y-strainer clean and running is essential for maintaining its use. Your system relies on the Y-strainer to protect pumps, meters, control valves, and more.

Drain Valve

Next, open the drain valve on the bottom of each tank for approximately three seconds to dump any settled solids into the pit. The valve at the bottom of the Processed Water Tank should be slightly open. This allows a small trickle of water to drain back to the return line and into the sump pump. Doing this will enable continuous circulation, which is necessary for maintaining the full efficiency of the microbes. 


After dumping out the drain valve, check that your system has adequate levels of microbes. If the level of microbes in your system is low, then you must refill it.


Along with checking for adequate levels of microbes, check whether your system has an adequate level of Coagulant. Similarly to microbes, refill it when needed if the levels are low. You need to also check that the dispensing knob is sitting at the top edge of the white area just below the 25. 

Cartridge Filter

Your next step is to check the condition of the cartridge filter. Our team recommends replacing the filter once per month. You shouldn’t replace the filter if there is a 20 PSI or more difference between the inlet and outlet gauges on the filter housing. In that case, you would then replace the filter sooner.

Remember that the cartridge filter is the last filtration stage before the water returns to your pressure washer. 

Water Quality 

When conducting your weekly maintenance plan, the final thing you need to do is to check the overall water quality. Do this to determine if the wastewater treatment system requires further attention. 

If you find that your system requires more maintenance, contact Evans for our scheduled maintenance work. At Evans, we go beyond selling the system to you; we also provide services to keep your equipment in working shape. 

With our routine maintenance, you stay ahead of the game. We tailor our program to keep your equipment running smoothly. The program helps you prevent unexpected issues and prolong your system’s lifespan, saving you time and money.
