Wahaso System Maintenance Guidelines & Support

Each Wahaso system is unique to some degree, with different sources and uses of water and different requirements for storage, treatment, pressurization and controls. While we engineer each system to require as little maintenance as possible, each still must be regularly maintained to continue operating properly. Note that the warranty on the system may become void if system is not properly maintained according to maintenance schedules.  

Included in every system delivery is an Operations and Maintenance Manual, and we provide on-site training on how to run the system correctly.

Wahaso does offer services for system maintenance and repair on a regular schedule, or as needed. Please contact us if you would like a quote on service.

General Guidelines for Maintaining a Wahaso Water Harvesting System

  • System Functionality Check – A weekly inspection should be completed to note overall system performance.  Important checks: Note alarms in the alarm history, active alarm conditions , chlorine readings, UV alarms, filter alarms, flow meter readings and pressure readings. All can be viewed via the alarm and status screens on the Wahaso display.
  • Water Quality Check – The simplest way to know how well your system is operating is to look at the quality of water coming from the filtration system. Cloudiness or any type of foul odor is a sure sign of a problem in the filtration system or upstream of the system.  Review the Water Aesthetics Rating (WAR) check list and and follow the guidelines for identifying potential problems.
  • Chlorination System or Cupridyne Supply (If applicable)- Check your chlorine or Cupridyne supply and add chlorine pucks or a replacement drum if necessary to ensure proper sanitation.
  • Bag Filter Replacement – A typical sock filter will require a cleaning or complete change approximately every 4 – 6 weeks. (Refer to your Owner’s Manual on how to change bags)
  • Water Quality Check – If you are not doing a weekly water quality check, the WAR scoring approach should be done on a more formal basis each month.  The results are a good indicator of the overall health of the system and treatment train.
  • UV Sanitation System (If applicable) – An inspection of ultra-violet sanitation system is required. The unit should be opened up and the quartz glass sleeves and O-rings should be inspected. Look for cracks in the sleeves and leaks or damaged O-rings. Clean the quartz sleeves by operating the wiper or manually clean to maintain clarity of the sleeve and UV exposure to water passing through the unit.
  • Level Sensors and Float Switches – Compare level reading to actual tank  levels. *Note: Level sensor fault signals will directly affect other system functions. Check that float switches are clean and moving easily with changes in water levels. Electronic sensors may need cleaning to restore their accuracy. (If service is needed, refer to the O&M manual.)
  • Pre-Filter – The pre-filter treats rainwater or stormwater before it enters the cistern. A properly maintained and operating pre-filter is the essential first stage in the system treatment train. A semi-annual cleaning/inspection of the system’s pre-filter will need to be completed. Depending on the unit, this step could be as simple as scrubbing a stainless steel screen or could require professional servicing of large units with a vacuum truck. Filters should always be checked after significant storm events and especially after long dry periods when more debris is likely in the first flush. (Refer to the Wahaso manual on how to perform this inspection and procedure – if the filter was supplied by Wahaso. If your filter was supplied by others, refer to the manufacturer’s manual for maintenance instructions).
  • Cisterns & Holding Tanks – Tanks will need to be checked for buildup. Inspections and cleaning may be necessary.
  • Self-Cleaning Filters – A semi-annual inspection and /or cleaning of these filters is required to keep the units in optimal running condition. (Refer to your owner’s manual on how to perform this task.)
  • UV Sanitation System (If applicable) – Bulb life is 8,000 – 9,000 hours – which is equivalent to 12 months of continuous operation. Frequent cycling on and off or overheating of the units can shorten bulb life. Replacement bulbs should be ordered from Wahaso at the 8,000-hour mark. (Refer to manual on how to replace bulb and clean glass sleeves)

Wahaso System Check – Water Aesthetics Rating “WAR” Score

Evaluating Processed Water Quality

After first checking for and addressing any system alarms, the next step in a system check is to evaluate the water output , or effluent, from the processing skid.

A visual water quality evaluation should be made as a first step in confirming that the system is properly processing water.  Regardless of the water source or intended use, the effluent should be Clear, Colorless and Odorless. If the processed water meets these three criteria and the sanitation system is operating properly, the water is likely safe for application.

Note: To confirm that the system meets the requirements of the NSF/ANSI Standard 350, and that the processed water is safe for exposure to the public, a sample of the effluent must be taken and evaluated by an independent test lab.

At Wahaso, we ask that you regularly check and record the effluent “WAR” Score – Water Aesthetics Rating.  It is a fast and simple way to document water quality day to day and before and after making system adjustments.

What Are the Implications for a Score Less than 100?
  • Any score less than 100 requires a review of the system operation – some aspect of the treatment train needs attention.
  • A total score of 90-95 points suggests that the effluent may be aesthetically unappealing, but is likely safe for continued application until the issue is addressed.
  • Scores less than 90 mean that a significant issue exists and should be addressed immediately. The water quality may create a health hazard and any use of the effluent should be discontinued until the problem is resolved.

Diagnosing and Resolving Water Quality Issues

When the system effluent is not clean, clear and odor-free, there is likely an issue somewhere along the water treatment train.  Proper system maintenance will keep the system working effectively and ensure an ongoing supply of high-quality non-potable water for reuse.  Each step should be checked on a regular basis to identify and resolve system problems.
