Water is a valuable resource, and watering is an essential part of our daily routine at Martineau Gardens, particularly during the warmer months. Using rainwater is much better for the garden, than turning on the tap to use mains water. Not only is the water softer, but it lowers our carbon footprint – energy is required to produce the drinking water that comes out of the mains water. With this in mind, Volunteer John Gale has been constructing a water harvesting system, that can collect and store rainwater. The rainwater is great for plants (but shouldn’t be used as drinking water.)
The sustainable use of resources, is a subject close to our hearts, here at the Gardens. With an eye for what can be reused and adapted, John has been collecting materials over the last few months. Our Friends and supporters have donated water butts, dustbins (now redundant following introduction of wheelie bins) and plastic storage containers, concrete slabs, bricks, a series of hosepipes, clips and taps which have been interconnected by John. The water is then capable of being siphoned around the Gardens. For the syphoning system to be most effective, the water source needed to be higher than the collecting chambers. John had spotted a wooden building on a higher level nearby. So with the support of our neighbours at Edgbaston Priory Club, John diverted a drainpipe so that the rainwater run-off is channelled into the collection chambers at Martineau Gardens. Located close to the vegetable beds, this new water storage system makes it much easier for the Garden Volunteer team to look after the crops growing. The pipeline now stretches from this wooden building (located at the Priory Road end) all the way down to the Hot House (see the plan and pictures at the end of this page). If you’d like to see the progress next time you’re at the Gardens, head for the polytunnel and follow the signs. Children will enjoy following the network through the Gardens, and at the same time find out how the process of syphoning works.

Plan of the Rainwater System in Place
Update April 2019
John is extending the system to reach the (work in progress) Pavilion Garden, which will make it easier and ‘greener’ for watering the plants in this area.
We are also seeking large dunk tanks (water header tanks) – can you help? Please call Gill on 0121 440 7430.
