We've had one of the wettest winters in history, and it would be easy to think that we have no issues with the level of potable water in this country. I've mentioned in previous blogs that there are other issues that suggest that water (or potential lack of it) is still a problem we need to address.…

Rainwater harvesting: where are the incentives?

The recent announcements surrounding the feed-in tariff (FIT) and renwable heat incentive (RHI), are (generally) fantastic news for the renewable industry. But the Government seems to have forgotten about rainwater harvesting. Whilst technically not a renewable technology, water is still an impor…

The wettest winter for years

With all the rain we've had recently, it's difficult to convince people that water really is in short supply for some of us. However, what we need to consider is where does it all go, and why, if it's so wet, is it scarce? To answer those questions very briefly: 1. Population is increasing, as…

Will it cost me more to harvest rainwater?

Rainwater harvesting systems tend to be pumped, causing people to ask the following questions : 1. "Does the cost of running the pump negate any savings made?" 2. "By running a pump, are we increasing our carbon emissions, and negating any environmental benefits?" Well, to answer those…

Rainwater harvesting: small is beautiful

When we think of rainwater harvesting, we tend to envisage a full scale domestic system with a large tank, say 4000 litres, buried underground, providing water to the toilets, washing machine et al.

Dealing with silt in your rainwater harvesting system

Over time, silt will build up at the bottom of a rainwater tank. Imagine you have a bucket of mud and water. If you leave it, the mud will settle at the bottom leaving clear water at the top. If you then empty another bucket of water straight in, the pressure of this water stirs up the mud, making t…
