How Bore Hall Saves Free-range Egg Producers £ 5,000 / year

Installing a borehole to draw a private water supply will save about £ 5,000 a year in Pembrokeshire’s free range egg business.

Lynn and Carol Jenkins diversified from dairy to poultry in 2013, with two 4,000 chickens flocking to Doreen Hill near Harborford West.

The couple set up an egg-producing company at the Greenfield site with two 9x66m movable flat deck houses procured pre-owned from a Lincolnshire unit.

To stack up 8,000 birds and numbers, they set efficiency targets to minimize production costs. Establishing your own water supply checked that box.

Even in the driest conditions on the farm, the water was visible about 1m from the surface, so the Jenkins family was confident in finding a water source not far away.

Drilling depth

Bore holes usually need to be excavated up to 30-60m, but can be as deep as 100m. After the investigation at Dreenhill, the borehole sank to 60m, reaching sufficient supply.

The system has a submersible pump at the base of a 4-inch pipe and a receiving vessel at the top.

When the amount of water in the container falls below a certain level, the pump will operate.

The only input cost is salt to keep the pipes clean.

Bore hole setup and running costs

The deeper the borehole, the higher the cost of capital to establish it. Jenkins spent a total of £ 5,678 on them.

  • According to geology, the drilling cost is £ 35-65 / m.
  • Bore hole packing and lining £ 21 / m.

Besides, the cost of electrical equipment was as follows:

  • Connect with transformer £ 9,720

In addition, continuous running costs include:

  • Pump replacement (every 24 months) £ 450
  • Annual service £ 400.

“This is the same type of salt used in dishwashers,” says Jenkins.

“Add to the brine bath in the same cabin as the filtration system and it will be automatically flushed through the pipe every night.”

Since the system was installed, water costs have been significantly reduced, saving £ 5,000 a year.

“There is no tap water. Everything, including the water in the house, is flowing out of the borehole.”

Water demand for poultry systems can be as low as 600 liters / day, reaching 1,600 liters / day during the recently introduced emergency housing measures to curb the spread of bird flu.

Pump and electricity

Haydn Lloyd, a pump and water system specialist at St. Clears’ Allpump Services, supports Dreenhill’s borehole system.

The cost of the pump can fluctuate and depends on the depth of the borehole, the water flow and pressure requirements of the system.

Lloyd said the distance that water must travel from the borehole to the place of use is also a consideration.

The Jenkins family replaces the pump with a readjusted pump every two years for around £ 450, and system maintenance costs £ 400 a year.

Do I need a water extraction license?

The 2003 Water Law allows anyone to extract up to 20,000 liters per day without a license or fee.

For larger quantities, abstraction licenses should be obtained from the Environment Agency or the equivalent authorities of the delegated country.

Because the site is off-the-grid, the pump and the rest of the site were initially powered by a 24V solar system. It has partnered with a small petrol generator to back up when the energy from the sun is inadequate.

However, three-phase electricity is also installed so that surplus energy can be sold to the grid.

Supply quality and continuity

The accumulation of micronutrients such as iron, manganese, and sulfate in water may be associated with the syndrome of certain diseases of birds.
Finding micronutrients at certain levels is common and may not be high enough to cause problems.

Tap water is evaluated by the supplier, but in the case of a borehole supply unit, the responsibility for testing lies with the farm.

Chemical analysis of water on the Jenkins farm showed high levels of iron and manganese, so filters were installed. A UV filter is also attached to remove bacteria.

The frequency and acceptance level of testing depends on the assurance scheme in which the farm works and should be performed in a certified lab.

Iron also promotes the growth of certain bacteria, which can lead to the formation of biofilms in the pipeline, but it also affects palatability.

Shallow boreholes, depending on location and drainage, can increase the load of heavy metals after heavy rains, and damage to supply pipes can contaminate the underground.

Whatever the water source (main or borehole), it is advisable to have a storage tank capacity to maintain a supply that lasts for at least 24 hours in the event of a problem.
