Rain Harvesting Maintenance

When it comes to maintaining your rainwater harvesting system you should find the process relatively hassle free, but as with any system, regular inspection is the name of the game.

After all, prevention is always better than cure.

1 – 3 Months

The most obvious thing to check is that all your pipes and gutters are kept clear and are in working order. Removal of debris and maintaining the structural integrity of guttering and down pipes will ensure proper water flow and prevent water loss from the system.

It’s a good idea to ensure that foliage is cut back and that overhanging branches are not causing a problem.

You’ll also want to ensure that there has been no buildup of smaller particles in your leaf trap screens. If in doubt you can remove the screen and give it a quick rinse to remove any finer debris.

Along with checking that there are no problems with rainwater catchment, you should make sure that your first flush system is kept clear.

While you are inspecting the system you should be checking for any sign of leaks. Not only does this represent a loss of water, but it might also be indicative of pressure problems in the tank.

Keep an eye out for any obvious physical build up in your tank or any possible contamination by insect larva.

A cursory inspection of the catchment area and collection system should be carried out at least every three months.

6 Months

At the six month mark it’s a good idea to replace your filters and make sure that your water pump is still performing properly. It is possible to do this yourself, if you have the knowhow, but it is often beneficial to consult an expert when it comes to your pumping system.

Aquamat offers maintenance contracts to ensure that our client’s systems are kept running at optimum efficacy.

Make sure that your pump still switches on and off and that it is protected from the elements.

If your pump is switching itself on and off or you are having problems with pressure this could be indicative of a leak in the system.

1 Year

Your rainwater harvesting system should be given a full inspection every year. You’re not just looking for the obvious problems, but the little things that creep in over time.

A good way of ensuring that everything is okay is to use your annual system check as an opportunity to get the quality of your water tested.

If you have a UV light installed in your system it may need replacing.

2-3 Years

The cycle of inspection and maintenance should ensure smooth operation for your rainwater harvesting system, but sediment inevitably builds up over time.

If you want to ensure that the quality of your water doesn’t decline, you should drain and clean your tank at least once every two to three years.

This procedure should be as simple as opening the outlet valve to let sludge and sediment drain.

Flushing the tank will ensure that you have cleared any build up.

Rainwater Harvesting


There is no hard and fast rule as to when problems may arise. If you notice any tell-tale signs like water discoloration or changes in taste or pressure, then it’s best to start looking into it right away.

That said, any well maintained system should give you peace of mind for many years.
