How Does a Borehole Water Supply Work?

What is a borehole?

A borehole is a very narrow hole drilled down through the earth. For irrigation purposes the borehole is drilled to reach the water in an aquifer, it is a much more efficient way of reaching water than digging a well. An aquifer consists of porous rock that is filled with water. Before a borehole is drilled it is important for a survey to be done to ensure that the likelihood of finding water is worth the drilling costs.

Irrigation Pumps

Irrigation pumps are designed to provide sufficient pressure and water flow for an irrigation system. Sometimes an irrigation pump is specified as the main water supply is not capable of providing the pressure and flow required, this is especially true for pop-up lawn sprinklers and large sprinkler sets in horticulture. Irrigation pumps are also required where the Water Regulations require a break from the public water main - most commercial irrigation systems need this by law. The break from the mains is normally achieved using a water storage tank, generally called a break tank.

ISO 9001 accreditation

Access Irrigation is pleased to announce that it has been accredited with the prestigious ISO 9001 quality standard.

Hose Pipe Ban Allows Drip Watering

The temporary ban on water use (hosepipe ban) being implemented by United Utilities from 5th August 2018 will ban the use of hosepipes and sprinklers to water domestic gardens. There are however a number of exceptions:

Water Hammer - it's Causes and Solutions

Causes of Water Hammer

Like any other moving fluid, flowing water has momentum.  When subjected to a sudden change in flow, shock waves propagate through the system.  This occurrence is referred to as ‘water hammer’.  Flow changes can occur due to the operation of valves, the starting and stopping of pumps, or directional changes caused by pipe fittings.  Other causes may be the rapid exhaustion of all air from the system or the recombination of water after water column separation.

Water Regulations for Non-Domestic Dwellings

The use of mains water in England and Wales is regulated by the Water Supply (Water Fittings) Regulations 1999, an Act of Parliament which lays down what can and cannot be done with drinking (potable) water supplied by the water companies. The Act contains two important principles: water should not be wasted and water should not be contaminated.

In order to comply with the first principle, it is important that the water provider is contacted before an irrigation system is installed, with information on what system is being proposed.

Water Regulations for Domestic Gardens

Understanding Domestic Water Supply Regulations

Most people are unaware that there are legal requirements to take into consideration when connecting an irrigation system to a domestic garden tap. This simple guide provides you with the information you need to make sure you stay on the right side of the law!

What you can connect to the mains water supply is regulated by an Act of Parliament - the Water Supply (Water Fittings) Regulations 1999; these regulations supersede the old water bylaws in England and Wales.

Permadrip compared to Porous Hoses

Porous hoses and ‘Leaky Pipe’ type drip systems are very popular; but are they as technically capable as commercial drip lines such as Permadrip?

Pozilock fittings - more secure than barbed fittings

Barbed fittings are a neat and low cost method of putting fittings into low pressure irrigation systems such as border drip lines.

Sports pitches now covered under Water Restrictions

Under previous 'hosepipe bans' only the washing of cars and the watering of domestic gardens was restricted. The 2012 restrictions however use new legislation that has been passed since the last drought. This widens the scope of the restrictions and now covers sports pitches that are not used for international matches.

These new restrictions will adversely affect club level rugby, football and bowls clubs.
