Tank Sanitation

Caravan Water Tank Sanitation Protocol

This protocol describes a simple method for disinfecting caravan water tanks and maintaining hygienic potable (drinking) water.

Preparation of the Water Tanks

Before initiating the disinfection process, we recommend the following preparation steps:
1. Drain all existing water from the tanks.
2. Rinse the tanks thoroughly with clean water.
3. Remove any visible debris or organic material.
4. Ensure the tanks are drained from the lowest outlet point or the furthest tap in the system.

Proper cleaning before disinfection improves the effectiveness of the sanitising process.

Disinfection of the Water Tanks (Deep Clean)

To disinfect the tanks, a 1% peroxide solution is recommended.

Tank volume:
• 2 tanks × 70 litres each
• Total capacity = 140 litres

Solution required: To prepare a 1% solution:
• Add 3 litres Peroxsil
• Add 137 litres clean water
• Total solution volume = 140 litres

Procedure
1. Begin filling the tanks with clean water.
2. Add the Peroxsil at the same time as the tank is filling to ensure good mixing and agitation.
3. Continue filling until the tanks reach full capacity (140 litres total).
4. Allow the solution to stand in the tanks for a minimum of 48 hours. A longer contact time may further improve disinfection.
5. After 48 hours, completely drain the tanks.
6. Flush the tanks thoroughly with clean water.
7. After this process, the tanks should be free of harmful microorganisms.

Sanitising Potable (Drinking) Water

Once the tanks have been disinfected, the water can be maintained in a hygienic condition using a low maintenance dose of Peroxsil.
Dosage for potable water
• Add 5 ml Peroxsil per 70 litres of water
• For 2 tanks (140 litres total), add 10 ml Peroxsil
This dosage provides approximately 50 parts per million (ppm) hydrogen peroxide, suitable for maintaining potable water hygiene.

Procedure
1. Fill both tanks with clean drinking water (140 litres total).
2. Add 5 ml Peroxsil to each 70-litre tank (10 ml total).
3. Add the product while filling the tank to ensure proper mixing.
This concentration helps maintain clean, safe drinking water by controlling microbial contamination and biofilm formation within the tank and water system.
