System Maintenance Services

Rainwater Harvesting Systems should receive a full service every six months to ensure safe and efficient operation. Systems that lack regular maintenance are at risk of failure, potentially resulting in no water for the outlets served by the system.

Even without any obvious defects, Greywater Recycling Systems should be thoroughly checked during a service every six months to ensure optimal operations.

Rainwater Harvesting Systems should receive a tank clean every 2-3 years, depending on the site location. Sites located close to densely forested areas, or the coast may require more frequent attention due to increased volumes of debris.

Regular cleaning of the primary storage tank and any accompanying header tanks (if installed) is crucial for maintaining optimal water quality. Neglecting this maintenance can result in discoloured rainwater in outlets.

As time passes, particles collected from the roof surface can accumulate at the tank's base. Allowing sediment to accumulate can disrupt system functionality by impacting submersible pumps, reducing usable storage capacity, and damaging internal components.

Poor water quality is an obvious sign that your Rainwater Harvesting System requires a tank clean. You can check this by inspecting outlets served by the system or completing a visual check of the rainwater stored in the tank.

NO! Installing a mains water bypass because your Rainwater Harvesting or Greywater Recycling System has failed is a direct breach of The Water Supply (Water Fittings) Regulations 1999 and poses a risk to public health. Failure to comply with these regulations is a criminal offence and the company responsible for the bypass can receive a fine.

There is a misconception that if your Rainwater Harvesting or Greywater Recycling System has failed, you can install a mains water bypass to allow outlets that were previously supplied by the system to use mains water instead. This is a big no-no in the water industry!  

Rainwater or greywater pipework must be separated from the mains water supply via a WRAS-compliant air gap. Air gaps are included within any rainwater or greywater system; therefore, a bypass cannot be installed around this air gap.

What is the alternative?

If your system has completely failed and is deemed beyond economical repair, you can entrust us to install a completely new rainwater or greywater system. Alternatively, our engineers may be able to get the mains water top-up function on the system working once again. Speak to our specialists about this.

Decommissioning is a lengthy and expensive process as all associated pipework needs to be fully chemical cleaned. That’s why regular servicing is always the best solution in the first place.  

Yes! Our engineers are fully trained to maintain Rainwater Harvesting and Greywater Recycling Systems supplied by others. First, we will carry out a system assessment to determine the operational status of your system. 

Many systems supplied by others in the UK are manufactured in the same facility in Germany meaning that we are highly experienced in dealing with these systems and stock many of the necessary replacement components.
