Agricultural Rainwater Tank Installers
At Dening & Co, we’re specialists in water preservation and installing rainwater harvesting systems for farmers and landowners throughout the South West, covering Somerset, Devon, Dorset and Wiltshire. Harvested rainwater has many uses in farming and agriculture, including crop spraying and irrigation. Additionally, with a few extra simple steps, harvested rainwater can be used as livestock drinking water.
Farmers are increasingly turning to rainwater harvesting because it reduces reliance on mains water, lowers water bills, supports sustainable farming and provides softer water that's better for crops.
​
Rainwater mixes more easily with chemicals and can significantly reduce the cost of chemical conditioners, while its crop-friendly PH is ideal for irrigation, helping to produce bigger, healthier yields.
​
We’re official stockists of Enduramaxx and we are happy to work with those receiving rainwater harvesting grants such as the upcoming FETF 2025 grant or the Capital Grant. If you’re interested in a rainwater harvesting system or you would like to expand on an existing one, speak to our team today and unlock your farm's potential!
Uses of Harvested Rainwater in Farming
There are many benefits and uses of harvested rainwater in farming and agriculture. Some of the main uses of harvested rainwater on farms include:
-
Crop Irrigation
-
Crop Spraying
-
Livestock Watering
-
Cleaning uses (i.e. outdoor areas, machinery)
-
Toilet flushing
-
Dairy washdown
-
General pressure washing
Additional settings where rainwater can be used for irrigation and cleaning purposes include orchards, vineyards and nurseries/garden centres.
​
When space is limited or frost-protection is required, underground rainwater harvesting systems can be used to store large amounts of water.
​
Agricultural rainwater harvesting systems can pay for themselves in as little as a year, reducing mains water usage significantly to make it a great investment.

The Benefits of Agricultural Rainwater Harvesting
Along with the many uses of harvested rainwater in farming and agriculture, there are many benefits too, including:
​
-
Reduced mains water usage and costs
-
Larger and better crop yields
-
Rainwater is typically preferred by livestock
-
Can reduce risks of flooding and pressure on storm drains, giving somewhere for all the water to go during heavy rainfall
-
Better for the environment and creates sustainable agriculture
-
Provides a backup water supply
-
Reduced surface water drainage costs
-
Farm buildings are typically large with a big roof area, meaning they are great for harvesting large amounts of water
-
Can be fitted with a mains-supply valve that tops tanks up when supplies are low or in times of no rainfall

Rainwater Harvesting Grants For Farmers
​
There are currently several grants for farmers and landowners that can be used to partially fund rainwater harvesting systems.
These grants include the Farming Equipment & Technology Fund (FETF) 2025 along with the Capital Grant and Water Management Grant, both of which include funding for rainwater harvesting systems.
We are pleased to work with those who have applied for these grants, and we have numerous clients who have had their rainwater harvesting systems funded through these grants.
We also have several rainwater harvesting kits which are grant-eligible items and can be used with our rainwater harvesting tanks.
​
The bigger your farm buildings, the more rainwater you can harvest. There are two FETF rainwater harvesting grants: one for 5000L rainwater systems and one for up to 50,000L systems.


Watering Livestock With Harvested Rainwater
With emerging advancements in rainwater harvesting technology, with the right filtering and treatment processes, rainwater is perfectly safe for livestock to consume.
​
Most farm animals typically prefer the taste of rainwater, which unlike treated mains water is not chlorinated and is softer.
​
Cattle, pigs and sheep in particular consume very large amounts of water on a daily basis, making rainwater harvesting the perfect way to reduce livestock farming costs.
​
Rainwater tanks can be connected to towable livestock water bowers or fed straight into livestock drinking water troughs.
​
It is worth noting that rainwater does lack the minerals found in mains water, so it is advisable to supplement the rainwater to ensure the health of your livestock.
