Borehole drilling is a technique that allows you to access underground water sources by creating a deep and narrow hole in the ground. In this blog post, we will explain what borehole drilling is, how it works, and what are its benefits and challenges.

What is borehole drilling?

Borehole drilling is a process that involves using a rotary drilling rig to drill a hole into the ground, usually between 50 and 100 meters deep. The hole is then lined with steel casing and fitted with a pump that can extract water from the underground aquifer. The water quality and quantity depend on the geology of the area and the depth of the borehole.

How does borehole drilling work?

Borehole drilling requires a geological survey to determine the best location and depth for the borehole. The survey also helps to estimate the water yield and quality. Once the site is selected, the drilling rig is set up and the drilling begins. The drilling method can vary depending on the soil type and conditions, but it usually involves using compressed air or drilling fluids to remove the cuttings from the hole. The drilling process can take from a few hours to several days, depending on the depth and diameter of the borehole.

Once the borehole reaches the desired depth, it is lined with steel casing to prevent it from collapsing or getting contaminated by surface water. The casing also acts as a pre-filter for the water. A wellhead is then installed to seal the borehole from any possible surface contamination. The next step is to install a pump that can lift the water from the borehole to the surface. The pump can be either submersible or above-ground, depending on the power source and preference. The pump is connected to a pressure vessel that regulates the water flow and pressure. The final step is to test the water quality and install any necessary filtration or treatment systems.

What are the benefits of borehole drilling?

Borehole drilling has many benefits, especially for rural areas or places with limited or unreliable access to mains water. Some of the benefits are:

- Borehole water is natural and free of chemicals, unlike mains water that may contain chlorine or fluoride.
- Borehole water is sustainable and independent of weather conditions, unlike surface water that may be affected by droughts or floods.
- Borehole water can save you money on your water bills, especially if you use a large volume of water for domestic or commercial purposes.
- Borehole water can increase the value of your property, as it provides an alternative source of water that can be used for irrigation, livestock, or leisure facilities.

What are the challenges of borehole drilling?

Borehole drilling also has some challenges that need to be considered before deciding to invest in one. Some of the challenges are:

- Borehole drilling requires a professional contractor with experience and expertise in geology, hydrology, engineering, and environmental regulations.
- Borehole drilling can be expensive upfront, depending on the depth and diameter of the borehole, the type of pump and piping system, and the water treatment requirements.
- Borehole drilling can have environmental impacts, such as noise pollution, soil erosion, groundwater depletion, or contamination.
- Borehole drilling requires regular maintenance and servicing to ensure its optimal performance and safety.

Conclusion

Borehole drilling is a viable option for accessing underground water sources that can provide you with clean, natural, and reliable water for your home or business. However, borehole drilling also involves some costs and risks that need to be carefully evaluated before making a decision. If you are interested in borehole drilling, you should consult with a reputable and qualified contractor who can advise you on the feasibility, design, installation, and maintenance of your borehole system.

where are the tunnels?

Are you curious about the tunnels in Chichester? If you are, you are not alone. Many people have wondered about the existence and purpose of these underground passages that are said to run under the city. Some claim they have seen them, others have heard stories about them, but what is the truth behind the mystery?

In this blog post, I will try to shed some light on the tunnels in Chichester, based on some web searches and historical sources. I will also share some of the rumours and legends that surround them, and invite you to share your own experiences or opinions in the comments section.

What are the tunnels in Chichester?

The tunnels in Chichester are a network of underground passages that are believed to date back to Roman times or earlier. They are said to follow the old foundations of the Roman wall on the east side of the city centre, and to connect various buildings and landmarks, such as the cathedral, the market cross, and the crypt.

The tunnels have been rumoured to serve different purposes over time, such as smuggling routes, secret passages for clergy, hiding places during the Reformation, or escape routes during wars or invasions. Some people also think that poet John Keats used the tunnels for inspiration when he wrote The Eve of St Agnes in Chichester in 1819.

However, there is little concrete evidence to support these claims, and most of them are based on hearsay or speculation. The tunnels have been blocked off or filled in over time, making them inaccessible or invisible to most people. Only a few traces of them remain, such as a blocked-off passage in the cellar of Hansfords Menswear shop, or a dark tunnel under the crypt where a schoolgirl claimed to have visited in the 1940s.

What do experts say about the tunnels?

The existence and origin of the tunnels in Chichester have been a subject of interest for archaeologists and historians for many years. However, they have not been able to confirm or deny their presence or function with certainty.

One of them is Claire Mandville, She has been researching the tunnels in Chichester for a while, and has interviewed several people who claim to have seen or heard about them.

She said: "There's definitely something there but it's hard to say what it is. It could be anything from drainage systems to cellars to actual tunnels. It's possible that some of them were used for smuggling or other purposes but it's hard to prove. I think they are fascinating and I would love to explore them if I could."

Also plans to expand his research and investigations on the tunnels, and to involve more of the local community in his project. She said: "I think it's important to document them before they are lost or forgotten. It's a great way to engage people with their local heritage and culture."

What do you think about the tunnels?

The tunnels in Chichester remain a mystery that intrigues many people. Whether they are real or not, they have inspired stories and legends that add to the charm and character of the city. What do you think about them? Have you ever seen them or heard about them? Do you have any theories or questions about them? Let me know in the comments below!

The Punch house

punch house pub

ON THE south side of East Street, close to the Market Cross, lies number 92 which up until fairly recently was The Royal Arms public house (also known as Ye Olde Punch House).

Although the façade dates to the Georgian era, the building is of a timber-framed construction said to date from the 16th century.

 Much of the original building survives including highly decorated plaster ceilings displaying the Tudor Rose and fleur-de-lis.

 It was once a private town house belonging to the Lumley family of Stansted.

summeerdale football ,I have an update on the old newspaper article relating to Summersdale and the tunnel found under a football pitch. I sent an email to the Summersdale Residents Association, and they were extremely helpful with one of the members being able to identify a location for the site of the pitch. Looking at some old maps and combining the documents from Liam Mandville
regarding subsidence etc. the area between The Avenue and Highland Road (on the Eastern side), does fit well as to the location. Many of the properties built on this site have substantial gardens so there may still be something to find that could explain what was found by the groundkeeper all those years ago? ,5f6f8e5fb6881-116345275_10157348686446892_326855352233187857_n.jpg,5f6f8e5fb7b45-116168775_10157348685396892_1033817068655264665_n.jpg
