Operation and Maintenance of Water Treatment Works

The foundation for the effective and efficient Operation and Maintenance of a Water Treatment Works is having an efficient inspection process in place to give you an even finer control over the operational and maintenance processes that follows. We do this by setting up the most appropriate set of Inspection Routes, specific objects that comprise a route and various triggers that generate work orders. We then define exactly what it is that has to be examined on a route (and on an individual object), how it has to be examined and the conditions under which it should be examined as well as any other criteria that our clients wish to apply. We would also set up inspections for a category of objects (like the Water Treatment Plant) or an individual object (Water Pump).

We address the inspection in three parts: Routine Inspections, Risk Based Inspections and Monitored Data.

• Inspection Point

An inspection point identifies what area of an object should be examined (the physical location on an object).

• Inspection Aspect

The inspection aspect identifies what is being measured during an inspection.

Raw Water Quality

Moderate or large quantities of nutrients such as phosphates, nitrates and organic nitrogen compounds may act as a fertilizer in a reservoir to stimulate the growth of algae which may cause algal bloom.

Regular inspection (analysis of raw water quality), preferably once in a week in large water treatment plants is necessary to identify and correct the problems likely to be faced in the water treatment. Samples would be taken and sent to a laboratory for testing. On completion of the tests, the laboratory personnel would enter the results into our system. If the results fall outside the parameters that we have set up in the system, an appropriate work order would automatically be generated and assigned to a suitably qualified serviceman.

Preventive Maintenance Procedures

The Water Supply Systems' preventive maintenance procedures are incorporated into the Work Orders. These procedures are customised to our client's specific needs to accommodate their designs. Amongst others, we have incorporated the following preventive maintenance procedures into our overall work management solution:

• Flow Measuring Devices
• Chemical Feeding Unit
• Flash Mixer
• Flocculator
• Clarifier or Sedimentation Tank
• Rapid Sand filters
• Chlorinators
• Clear Water Storage Reservoirs
