General Water Purification

To make water safe to drink, always refer to local guidelines.  Depending on the level of bacterial and faecal contamination, a wide range of dosing strengths may be required: As a general guide:

Low Risk areas – 2 ppm or (2 mg/L) and generally 10 minutes contact time minimum

Medium Risk areas – 4-5 ppm or (4-5mg/L) 10 minutes minimum

High Risk areas – 10-20 ppm (10-20mg/L) with extended contact times of up to 20 minutes

It is important to test the water after treatment, especially as the risk increases.  This can be done with simple test strips which measure in 0, 1, 3, 5 & 10ppm bands using a colour coded reagent test (use PN944 4 way test strips)

Well Water – new or contaminated

Make up 25 tablets in 25 Litre solution

Pour half into the well, operate pump until Chlorine is detected.

Stop pumping and add remainder of solution to well.

Leave for minimum of one hour.

Pump again, ensuring all domestic taps are open.

Check for Chlorine smell at each tap, then turn off.

Wait 12 hours before checking for a minimum of 2mg/litre (2ppm chlorine/Litre)

Refill the system with potable water.

Spring Boxes or Silt Traps

Make up 25 tablets in 25 Litre solution.

Using half the solution thoroughly scrub inside walls with the Chlorine solution paying particular attention to the highest and lowest water line levels.

P:our remaining half of the solution into the Box/Trap.

If there is a pump, repeat steps 4 to 8 (see Well Water Instruction above.

Chlorine odour can linger and this may take a few days to disappear.

Important Note: 

Always test for residual Chlorine smell or Chlorine reading before drinking.  If no residual Chlorine smell, retreat.  Ground water will invariably be cleaner than surface water.

Water Source Conditions to be aware of:

Faecal contamination is VERY DANGEROUS – avoid if suspected.

Industrial pollution – avoid if suspected.

Foul smelling water – possible algae contamination.  Filter if possible

Turbidty – if Turbidity measures NTU 5 or above then water must be filtered.
