WHAT THE STANDARD IS: Through a system wide commitment to scheduled and preventive maintenance, Splash is able to decrease infrastructure system downtime while also decreasing annual maintenance costs.  The scheduled and preventive maintenance is performed by Splash technicians, 3rd-party service technicians, and/or the partner site's maintenance staff.   Splash's maintenance system consists of semi-annual Routine Monitoring visits by Splash's M&E staff as well as an annual maintenance visit performed by Splash's infrastructure technicians.  The M&E staff inform the Splash Infrastructure team if there are any issues or oddities regarding the Splash infrastructure at the site.  During the annual maintenance visit performed by the Splash Infrastructure team, the technician will perform the annual maintenance that is required for the water filter system as well as perform a full examination of all Splash infrastructure on site.  If there are any problems that Splash is responsible for repairing (as per the MOU) then the Splash technician will perform the necessary repairs during this visit as well.  These visits occur throughout the length of the MOU.  The annual Splash infrastructure visits should take place at the same time as the scheduled replacement of any consumable parts of our installed infrastructure.  The Splash infrastructure maintenance visits can be coordinated with the scheduled Routine Monitoring visit performed by the local M&E team so that both visits can be completed in a single trip.  

In addition to the full list of O&M tasks listed below, Splash technicians should also use their maintenance visit to meet with the partner site management about any concerns or problems that they have had with the Splash infrastructure.  The technician can also lead a refresher training for the partner site's maintenance staff for all of the Daily, Monthly, Quarterly, and Troubleshooting tasks listed.  For the full list of O&M tasks, please see the attached list below, most of these tasks are to be performed by the partner site unless clearly stated otherwise:

Filter Systems

Daily:

• Make sure water is flowing through the filter system
• Make sure that the system backflushes properly

Monthly:

• Press red button on top of the carbon filter until a few drops of water come out of the button.  You should do this more than once a month if there is a lot of air that comes out of the button before the water.

Quarterly:

• If strainer housing is not transparent then open strainer to see if it is dirty.  If dirty, physically clean the mesh or discs with a brush.  Do not use any cleaning solutions or chemicals.
  • To open the strainer, first close the valve directly before the strainer (upstream), and then close the valve directly after the strainer (downstream).
  • Next, hold the top of the strainer in place while unscrewing the bottom of the strainer.
  • Use a brush (like a toothbrush) to clean off any dirt from the strainer mesh or discs.  Placing the strainer underneath the running water at a handwashing station can also be helpful.
  • Since the mesh strainer is easily bent, extra care must be taken when placing the mesh strainer back into the strainer casing.
• If strainer housing is transparent, clean the strainer whenever you see that it is dirty.

Annually:

• Splash, or a Splash approved technician, will change out the carbon filter with a new one

On the first day after a long holiday break:

• Before anyone drinks from the drinking taps, press the ‘Flush’ button on the ‘ABCD’ backflush controller, and then open every drinking tap and allow water to flow through the system for at least five minutes.

Troubleshooting the Filter System

• Water not flowing through system, or very low rate of flow
  • Ensure that water is available and that the booster pump (if present) is plugged in and in good working condition.
  • Press the red button on top of the carbon filter to clear air out of the system.  Press the button until some water comes out of the button.
  • If water is still not flowing, press ‘Flush’ button on the ‘ABCD’ backflush controller to cause a manual backflush.  Press this button up to 5 times if water is still not flowing.
  • If water is still not flowing, call Splash (local phone number)
• Water has a bad taste or smell after going through the filter system
  • Call Splash
• Water is not clear or is discolored after going through the filter system
  • If water appears cloudy or white, observe the water for two minutes.  If the cloudiness or white color goes away within this time, then it was simply thousands of tiny air bubbles causing the water to look cloudy or white, and the water should be safe to drink.  
  • If the cloudiness or white color does not go away after a few minutes, or if this cloudiness turns out to be small solid particles, call Splash
  • If the water is any other color, or is visibly dirty, call Splash
• Filter system is leaking
  • Call Splash if any part of the filter system is leaking

Stations

Daily:

• Wipe down the surfaces of the stations
• Make sure that every handwashing station has soap available at the station
• Clean the mirrors above the handwashing stations
• Make sure that all handwashing and drinking taps are functional. Every tap installed by Splash should be functional every day.
• Clean all drinking taps with a chlorine bleach solution
  • Wipe the spouts of the drinking taps with a clean rag that has been wetted with a bleach and water cleaning solution.  After wiping the drinking tap, open the tap and allow water to flow through it for at least 30 seconds.  Do this for each tap.
• Wipe clean all handwashing taps

Troubleshooting:

• Water is leaking from a station or tap
  • The school should attempt to repair any leaking pipes on its campus.  
  • If the school is unable to repair the leak or if there is a larger issue with the plumbing, then the school should call Splash.
• Water is not properly draining from a station
  • The school should examine the drain piping for any issues, and should open the drain P-trap piping underneath the station to try to correct the drainage issue or remove any debris that is clogging the pipe.

 

Water Storage Tanks

Annually (preferably right before the first day back after a long break):

• Hire a professional cleaning service to clean every water storage tank on the campus used for drinking water, and make sure they do the following steps:
  • Drain the water storage tanks
  • If people must go inside the tank, ensure that anyone going inside the tank has fans for airflow into the tank
  • If people must go inside the tank, ensure that anyone going inside the tank has someone watching them outside of the tank with a safety plan in place
  • Physically scrub, spray, or otherwise remove any visible dirt, debris, algae, or other filth
  • Wipe the interior surfaces of the tank with a bleach solution
  • Spray the inside of the tank with water, then flush and drain all water used for cleaning.  Make sure that no water used for cleaning is used for drinking.

Sanitation

At least twice a day (more often if needed):

• Make sure that there is water available for flushing the toilets and urinals, and make sure that all flushing mechanisms and equipment works
• Clean every toilet and urinal
• Clean the lower walls and floors
• Clean all door knobs, locks, and door handles
• Remove trash from toilet and urinal stalls
• Safely and properly dispose of menstrual health products
• Report any broken equipment or leaks to managing staff

Every two weeks:

• Deep and full clean of every bathroom surface
  • Clean everything in and around each bathroom and stall so that it looks like it is new

Troubleshooting:

• Toilets or urinals are clogged or are not flushing
  • It is the school’s responsibility to maintain and repair the toilets and urinals, and to fix any clogs with sanitation
• Contact Splash if there are any issues, failures, or breaks with the installed equipment or doors within the first 2 years after they were installed.
