Good luck to Shauna Hynes and the Galway Footballers today in the All Ireland final Galway Ladies Football

A six-week hosepipe ban is now in force across Dublin and five other counties.

Nationally, domestic water use is running about 20% above typical levels, putting sustained pressure on reservoirs and treatment plants.

Every litre collected from a roof and stored on-site is a litre that doesn't have to come from an already-strained network, for garden watering, car washing, and other outdoor uses currently restricted under the ban.

As these warm, dry spells become more frequent, harvesting rainwater isn't just a temporary solution. It's a way to build resilience into how we use water day to day.

Could rainwater harvesting systems close that 20% gap?

📸 Some photos from a customer of a recent install, now settled in and doing its job.

A 14PE wastewater treatment system with a tertiary filter, installed near the shore of Lough Corrib, Co. Mayo.

Being this close to a lake, that tertiary stage matters. It's an extra level of polishing before final discharge, giving the water an added layer of protection.

Proud to get systems like this right, where it counts most.

Did you know? When temperatures rise in Ireland, water demand surges.

Uisce Éireann is already appealing to the public to conserve water, yet a survey conducted in early 2026 found that 31% of Irish adults described themselves as unengaged when it comes to water conservation.

That is almost one in three people giving little thought to how much treated water they are using, at a time when the network is already operating beyond capacity.

A rainwater harvesting system reduces your reliance on mains water for everyday tasks like garden irrigation, washing down yards and flushing toilets. During a warm spell, when demand on the network peaks, your system is drawing on stored rainwater instead.

📸 Another system in the ground.

This one is a 21PE oneAdvanced pumped wastewater treatment system with a tertiary filter, installed in Clifford, Co. Sligo, designed to treat and safely dispose of the wastewater from a development of apartments.

It's a great example of the flexibility of the oneAdvanced range. The same proven technology behind this 21PE install scales all the way to over 1000PE, making it equally suited to large commercial developments.

📸 322m³ infiltration tank, Barna, Co. Galway

Another stormwater management system in the ground, installed in just two days.

This particular tank was an infiltration system, which lets stormwater soak naturally into the surrounding ground to ease the load on drains and watercourses, rather than an attenuation system, which stores water in a sealed tank and releases it slowly into a sewer or watercourse.

Great work by the team.

Did you know? According to Met Éireann, Ireland recorded rain on more than 200 days in 2025, even in the drier parts of the country. In the west, it was closer to 260 days.

Yet Met Éireann also confirms that Ireland's rainfall patterns are changing, with an increase in both dry periods and heavy rainfall events. Longer dry spells, followed by intense downpours.

That means the water is coming. The question is whether it works for you or goes straight down the drain.

Rainwater harvesting captures water from your roof during heavy rainfall and stores it for when you need it most, whether that is flushing toilets, running washing machines, watering crops or washing down a yard.

It is practical, it is proven and it is designed for exactly the kind of climate Ireland is moving towards.

Did you know? According to the EPA's latest report, almost six out of ten septic tanks inspected in Ireland in 2025 failed inspection.

Many homeowners don't realise their system may be putting their drinking water at risk.

Three things make the biggest difference. Installing the right system for your site based on an EPA site suitability assessment, ensuring it is installed correctly, and keeping up with routine maintenance.

Rainwater soaks into a green field. On hard surfaces, it has nowhere to go.

That's why the same rainfall causes very different problems in a city than in the countryside.

Roofs, driveways, car parks and roads turn rainfall into runoff almost instantly, sending it straight into drainage networks that weren't built for that volume.

Attenuation systems hold that water back and release it slowly. Soakaways let it infiltrate back into the ground.

Manage rainwater where it falls.

Did you know? Since January 2024, the government grant for repairing or replacing a faulty septic tank or wastewater treatment system in Ireland has increased from €5,000 to €12,000.

This grant exists, but it can be difficult to get. If your system has been inspected or is due for an upgrade, it is worth researching.
