DWP Services specialise in Well, Borehole and Spring water supplies. We are able to test, contain, store, distribute and maintain your private water system. No matter if you are in the Cotswolds or in Yorkshire!
Here are some examples of private water systems installed from new. These allowed our clients to become self sufficient and save money on their water bills.
DWP Services had an enquiry from a client with a remote barn conversion with no mains water. What they did have was a spring on their land, where someone had previously attempted to install a potable spring water system.
It was safe to say the current system was not fit for purpose, nor even operational. DWP services provided a simple, long term solution whilst advising on required ground works. We specified exactly what the client needed whilst keeping within the clients budget:
We were able to provide a complete packaged solution. Including installing the new tank, laying all the required underground pipework and cable ducting. Then installing a completely new pumped water set-up in the designated pump room.
Our client now has over 1000 litres of stored spring water and are receiving 1.5l/sec and 4 bar water pressure!
Our client had a fixed speed pump running 24 hours a day to fill an old milk tanker on top of a hill. This tank then fed water via gravity to a farm and adjoining properties. The tanker was leaking and the pump kept failing, causing constant call outs. Our client asked us to recommend a long term solution providing them with a reliable water system.
We carried out exploratory trial holes and traced the spring source. Once we established the water quality we installed a catchment chamber and specified a 2000 litre water tank with combined pump housing.
Our tank was designed to allow spring water to gravitate into the tank from the rear, and once full, overflow back into its natural water course. Once the foundations were in place we installed a high specification twin multistage water booster set which pumps through a water filter and UV system.
With a design pressure of over 10 bar, we ensured the booster set was variable speed with a standby pump to ensure reliability. Once the entire unit was fully operational we carried out a water test to ensure potability and found that it was one of the best results ever seen in Gloucestershire!
Many estates have hundreds or thousands of acres and they all have one thing in common, they need water!
Often using mains water is expensive due to quantity needed on a daily basis, where either spring or borehole water can be utilised its often the way to go.
Investing in the right infrastructure is key right from the word go. By ensuring you have a quality long term solution to moving water the rest of your system will benefit and can be easily controlled.
A lot of customers instantly go down a borehole route which is expensive and can give no guarantees to water quantity or quality! It has been found that boreholes do not produce enough water or the quality is not treatable for potable use. If you have a spring or existing well supply this is the right place to start! If you kind go back to source, take a sample and it comes back as potable or treatable then you do not need to invest in a borehole, sounds good right?
By utilising spring water systems many estates, commercial and domestic properties have years of free, good quality water.
Water booster sets are used across the country for many applications. So no matter if its a school, office block, apartment block, hospital or hotel – all of these places rely hugely on pumped water to ensure water gets to where you need it, when you need it.
Water booster pump sets come in all different shapes, sizes and configurations. Because of this, every manufacturer has their own interpretation of how a booster set should be put together and how they should operate.
After years of operation, water booster set breakdowns can occur. This can range from any type of fault including leaking mechanical seals or electrical breakdown. Repairing the unit can be either a short or long term solution, depending upon its condition. Eventually the unit will require refurbishment or replacement.
DWP Services offer a complete packaged solution for any scenario. We are able to provide each client with a tailored solution to suit their needs. If cost is key we have a full understanding of cost effective solutions across manufacturers, and how they operate. Here are some useful facts on a couple of the main water booster set manufacturers to help you make the right choice for you.
Water booster sets have been hugely developed over the years with innovative space saving, energy efficiency and serviceability. There are a vast amount of manufacturers offering a large amount of options for customers to research. Luckily we have done this bit for you. As a result, we are able to specify the perfect booster set for your application, explaining all the pros and cons along the way.
Replacing an existing booster set can be a stressful experience; organising several trades to ensure minimal disruption to the system. DWP Services offers a one stop shop turn key experience for our projects. From a site survey, strip out, installation and commissioning; seeing every project through from start to finish.
Pressurisation units are designed to replace water that has been lost through system leakage. Most modern boiler and air con systems use a sealed system. Whilst these systems can be filled through a manual ‘filling loop’ this requires physically topping the system up by hand. Large systems can loose a considerable amount of water and when the water pressure becomes too low the system will fail. This is where a pressurisation unit becomes a requirement it can automatically top up a heating or chilled water system whilst constantly monitoring system pressure. A pressurisation unit can also give alarms in high pressure conditions giving a fault and shutting down plant in any type of fault condition.
Its important to have pressurisation units correctly calibrated along with expansion vessels to be set at the correct precharge. If either of these components are faulty or incorrectly set up unexpected faults or system shut downs can occur causing inconvenience and costly call outs
The new fifth generation Hydrovar is now available. The new HVL hydrovar is now easier to install and operate due to its new quickstart guide and intelligently designed wiring design, the new HVL variable speed inverter is backward compatible with the last generation HV4 inverter and can be configured to operate up to 8 pumps in sequence.
The new Hydrovar HVL features include:
The HVL inverter has been a serious contender in the variable speed market for many years. Its motor or wall mounted options ensures flexible easy installation for the end user.
If you require any variable speed specific advise, repair, replacement or installation services contact DWP Services for expert advise.
For further information on the HVL please see:
DWP Services have been using a range of variable speed pump controller for many years. We have found many of them have some advantages and some disadvantages. Here we will discuss a few to give you some guidance on what can be used.
After some years we have narrowed down inverters keeping in mind cost and performance, here is a short guide.
Motor mounted and wall mounted inverters –
Grundfos are the biggest pump company in the world. Their reliability cannot be beaten and the technology has clearly been heavily invested in. This ensures Grundfos stays as the household name of pumps and inverters bringing complete peace of mind. The main variable speed drives is the soon to be discontinued MGE inverter and the new Saver 1 and 2 inverter. The MGE inverter has a deep parameter list for a knowledgeable engineer to fine tune to the maximum for complete efficiency and peace of mind. But on the other hand the MGE inverter will work with the right configuration file and basic set up. It may not be running to maximum efficiency but will deliver water where you want it year after year.
The Saver inverter is the newer edition to the Grundfos family, this has a hugely expanded menu giving the customer complete configuration. Reliability and quality has not been compromised and reliability is still at the top of its game.
Grundfos are notoriously expensive to their top end products but believe you get what you pay for, if you want a long term reliable solution this may be the manufacture for you.
We are now on the 5th generation of hydrovar. The years have seen complete redesigns of the hydrovar inverter but in all truth the menu and performance values have not changed too much. If you have a hydrovar it is most lijeky its the 3rd 4th or now 5th generation. Luckily enough no matter which one of these you have you can now buy an inverter to communicate with any model through its compatability software. The hydrovar is a motor or wall mounted inverter that has a pump specific set up generally used for water boosting. The excellent mulit-pump communication RS-485 is a real game changer in the pump world due to its ability to constantly keep system pressure whilst adjusting parameters or switching between units. The Hydrovar is most definitely a highly regarded inverter in the market although fairly expensive.
DWP Services is a fan of the speedomatic water cooled inverter. These units are cost effective, user friendly and reliable. The speedomatic can supply up to a 10AMP water pump and has an integral pressure and flow sensor so no need for extra wiring. They may be made out of plastic and a little bulky but now come with a LCD backlight display and a Volt Free fault contact giving the customer the ability to install and alarm to the unit in fault conditons.
We believe this is a strong competitor in the variable speed market. This unit is wall or motor mounted just like the hydrovar and is very cost effective. The menu system is easy to navigate whilst giving a huge amount of adjustable parameters

Well pumps, borehole pumps, sump pumps and multistage pumps are some of the different types of water pumps that you can find. Water pumps can be useful in both businesses and homes to bring or move out water. That’s where DWP services come in. Here is a bit about each of the above.
Well pumps These are often used in more remote areas. Wells used to be a main source of water for many people and are still widely used across the world. Well pumps were designed to create a high flow of water and a substantial pressure to ensure even the most modern of homes can run directly from a single well pump.
Borehole Pumps Invented for high pressure at low flow for the deepest of boreholes. In most cases these pumps are installed in a borehole and the water is then pumped into a holding tank. The water is then either gravity fed to its final destination or pumped once again to ensure a sufficient flow are pressure for the end user.
Submerisble pumps can remove water in a basement or an external underground tank. They come in many sizes to work in a domestic application right up to the most demanding commercial installations. No matter if you have a basement that floods now and then or a storm a sewage application there is a submersible pump that can can for you.
Multistage pumps Found in higher pressure at high flow applications, these pumps come in end suction (horizontal) or vertical orientations. They are used across the world for pump clean water to its final destination from a water authority application right through to hotel.
The whole thing is submersed. A submersible pump must be fully and completely submerged in fluid, including the motor which is fixed to the body of the pump.
Pumps use water to cool the internal impellers, when a water pump runs dry it is no longer being cooled. Impellers are either metal or plastic, and both of these materials do not cope to well and getting hot! The mechanical seals are made of ceramic which then start to quickly wear and end up leaking. Ceramic used throughout a multistage pump can also shatter causing critical failure forcing the entire element to be repaired or in a lot of cases replaced.
A common question I get asked without doubt. Even though we refer to it as suction lift, pumps actually do not lift liquid. What they do is create a void by evacuating the air in the line. Atmospheric pressure on the liquid then pushes it up the hose and into the pump. Simple, right?!
Pumps tend to lift higher than most manufactures will recommend but if possible it is always best to avoid suction lift. When a pump is lifting water and not variable speed your pump does not know if it gets air locked it therefore runs dry and unless you spot it early and prime it once again critical failure is likely. Luckily we have many other solutions to hand such as inverters to set dry running alarms or even well pumps!
Cut In Pressure is the set pressure that the water pump turns on at. Alternatively, the Cut Out Pressure is set pressure that the water pump turns off at. Simple as that!
The most common reasons are probably from the following list:
Generally higher horsepower pumps put out more water. You’ll find different models of jet pump are designed differently. A ½ HP pump can provide water to a small house with one bathroom and just a couple people.
If you add to that a second bathroom that might be used at the same time as the first, then going with higher horsepower is going to provide the extra water you’ll need.
With examples of a houses with multiple bathrooms, multiple people, then you probably need to go with one of the 1 HP models.
The terms submersible and immersible sound similar, however, these two are strikingly different and I want to explain to you why.
Submersible pumps are a heavy-duty type pump for heavy-duty jobs. Immersible pumps are a more cost-effective option for lighter-duty applications in a nutshell but let’s delve into further detail.
Submersible water pumps have many industrial uses. They are completely enclosed and the motor is integral with the pump which is designed to run continuously submerged in water.
Submersible pumps are built with frames that are precision machined to ensure a tight fit between every component of the motor and pump. Submersible pumps typically have a specially designed dual seal design where the outer seal is lubricated and the second seal is located in an oil bath chamber in, or below, the motor housing for seal lubrication.
Although built for continual submersion generally these water pumps can also be placed in dry environments that only flood under rare circumstances. Based on their design, the motor may require an external source of liquid for cooling or have an intermittent run time rating when run un-submerged.
These pumps are typically used in applications where they help manage things like sewage, storm & drainage water and oily water.
Immersible water pumps have motors that are built with the intent that they may be submerged and continue running in the event of the rare flood. They are, however, not meant to be submerged under normal everyday circumstances.
These motors are built specifically to operate in a dry environment. They are built with a sealing system that can withstand being submerged under up to 30 feet of water for up to two weeks. Immersible water pump motors are designed with a drive endplate packed with moisture-resistant grease, instead of the oil chamber found in a submersible water pump.
Immersible water pumps are generally easier to service and are cheaper to operate and maintain than the aofrementioned submersible water pump. They are appropriate for use in underground storm water pump stations where the pump gallery is designed to function as an incidental secondary wet well for the very rare major flooding event. After this motor is immersed, it must be removed for inspection and a bearing change.

Low water pressure can be a sad experience for many homeowners, boosting mains water is becoming a common occurrence across the UK and beyond. Water booster pumps come in all shapes, sizes and quality.
DWP Service have experienced a wealth of domestic boosting systems to satisfy every application and budget, let’s go through some of the products available on the market.
By far the best quality unit on the market. Available in single or twin pump configurations with a range of stored water 175l to over 2000l stores water. With the vast range of options available you can ensure these units can fit in your given location. These units come variable speed as standard for energy efficiency, 1” full bore filling valve to ensure your booster set does not run out of water (if sized correctly) stainless steel pipework and the only recognised WRAS approved integrated booster pump and tank system on the market. These units can be sized for an apartment to a 15 bedroom mansion!
A cost effective and compact way of boosting water in a light to medium domestic application. These units come fixed speed as standard with a moulded tank around the water pump and controller itself. A disadvantage of the Grundfos home booster is the limited capacity. Luckily you can buy a slave tank to assist with giving you more stored water. If your property suffers from a poor water supply a Grundfos home booster may be the solution for you.
Xylem Lowaras answer to the grundfos home booster. Again cost effective and available to fixed for variable speed options. This unit comes in a blue steel structure so you don’t have to put up with visible pump and control equipment. 180 litre storage tank gives you enough reserve water to feed a light to medium domestic application. Its always good to ensure you have a good incoming water flow rate for this option as adding extra storage is not particularly straight forward.
Pedrello have worked hard to attack the market in the direction of the Scubatank. They provide a fixed and variable speed option and different storage volumes along with tank shape. When space is critical you can really fit one of these tanks in a space that suits you!
This is where DWP Services can help you even further. After looking at these options you may find none suit your application or budget. A bespoke system could suit your property by working to your budget and available space!
