The non-pathogenic elements of PLR rapidly out-compete harmful bacteria and result in an improved quality of effluent seeping into the surrounding soil. In addition to degrading the effluent, PLR overcomes anaerobic conditions in pit latrines preventing odours that attract flies.

Dosing

Initially there may be an historical build up of ‘porridge’ in your pit, especially if it has been abused. If this is bad, you will see dry cracks on the surface.
Method:

Step 1: Take a stout stick and poke deep holes.

Step 2: Pour the PLR into a bucket of dirty water and pour this into the holes.

Step 3: Make sure the PLR gets into the wet underlying sludge.

Step 4: Waggle the stick to mix.

Step 5: Add more water the following day, then each day until ‘loose’. If really bad, dose once a month for three months.

Step 6: Bubbles appear, level drops as PLR starts to work. Water is needed so bacteria filtrate thick sludge to break it down.

Communal set-ups

Initial treatment = 50g per cubic metre occupied volume, then 25g per cubic metre occupied volume (every three months).
Method:

Step 1: Calculate occupied volume round up (e.g. 5.35m3 calculated at 6 x 50g = 300g).

Step 2: Mix loose powder in bucket of (dirty) water and split dose the pit via stall seats.

Step 3: Use a long stick to mix into sludge.

Step 4: Add additional 50lt water per cubic metre occupied volume. Observe.

Step 5: Add water daily till solids slurry.

Step 6: After six months, cut dose to approximately 15g every three months.
