Rainwater collection system: hoo dis it wark?
Wi a collector, the water is taen frae yer roof. It’s first filtered afore bein stored: leaves, moss an ither big bits are taen oot. The rainwater is then pumped straight frae juist ablow the surface, abuin the bottom o the tank. This gies ye back verra clear water, guid eneuch tae feed yer toilets, watter yer plants, wash the car or clean the flairs.
While it’s quick an simple tae install an aboveground tank yersel, callin in a qualified professional gies ye a made-tae-measure, faultless install o yer rainwater collection system.
Pickin the richt tank
Several things decide which rainwater tank tae choose: its volume, the material it’s made o, an hoo it’s installed.
Underground tank or ootdoor cistern:
- The aboveground PVC cistern: is the maist affordable option an the easiest tae install yersel, but nae the bonniest tae look at.
- The underground polyethylene tank: is the healthiest collection system (nae evaporation, oxidation or contamination possible), ideal fer a wider range o uses: toilets, washin machine, wattterin…
The volume o yer tank will depend on:
- The amount o rainwater collected: this varies wi the size o yer roof.
- The rainfall in yer region: a bigger tank should be used if ye bide in a dry region. It lets ye store water up fer times when it rains less.
- Yer usage: this depends on hoo much ye use an hoo mony fowk bide in yer hoose
Ither things tae keep in mind:
- This includes the budget ye want tae pit towards yer install: it’ll also decide the size o yer tank.
A system that pays fer itsel fast
Aince the tank’s installed, ye’ll soon see the savins. Dependin on the rainfall in yer region, wi a roof surface o 150 m2, ye can save up tae mair than €120 a year per water collector. The startin investment, mair or less muckle dependin on the tank ye choose an hoo it’s installed, pays fer itsel gey quick.
Lastly, if ye want tae call in a professional tae install yer tank (a maun for an underground tank), mind an keep the invoice! Ye can be gien a tax credit worth 25% o the equipment costs.
