Percolation tests
On paper Percolation tests appear to be an easy thing to test yourself should you wish to have a soakaway for your sewage treatment plant. However, it’s extremely important that the test is carried out with pin-point accuracy to determine the porosity of your ground. Fortunately, at Sussex Water and Drainage we have all the equipment and knowledge to accurately ascertain exact
Vp measurements.

The percolation test involved excavating a 300mm square hole to a depth of 300mm below the proposed invert level of the discharge pipe. After carefully removing all loose debris we will fill the hole with water to the top of the 300mm mark and leave this to seep away overnight. We will then return and fill to the same point and closely observe the time it takes from 75% capacity to 25% capacity. Using a calculation of how much water has dispersed in the given time with the depth lost we can accurately read the average time in seconds (Vp) for the water to drop by 1mm.

This test will be trialed at least 3 times and will be tested across at least 2 holes.
If you think a percolation test is for you, get in touch and we’ll provide your answers!

Water Pipe Installation & Renewal
Sussex Water & Drainage are experts when it comes to water supply pipes.

Water Supply
We install underground water pipes to houses and farms, over any distance. From designing new systems to renewing old iron pipes with MDPE. There is no need to excavate across your garden or driveway, as we can bore underneath with our Impact Moles. The cost of a new plastic water supply pipe will depend on several factors such as; the length of pipework and the diameter of service pipe required to meet your requirements. Installation times can vary due to ground conditions and pipe length, however, in most cases we aim to renew your water service pipe in one day, with the water supply being disconnected for just a few minutes. For longer distances of water pipe installation, we have chain trenchers readily available to lay pipes neatly over longer distances.

Underground water pipes
Leaks along your water service pipe may become apparent in the form of a wet patch in your garden, or poor internal pressure. Poor internal pressure may also be caused by changes to the internal diameter in old lead or galvanised pipes due to corrosion.
Up until the 1970s, lead & galvanised service pipes were laid to domestic properties. By replacing these lead/galvanised pipes, you eliminate any undesirable lead content in your water supply.

Water Pipe Renewal
We have a dedicated team with a wealth of experience in water supply and replace old lead pipes/galvanised pipes with new plastic piping. The new pipe will be a blue plastic pipe which is made from Medium Density Polyethylene (MDPE).
From small domestic renewals to entire farm supplies, we have experience in using all types of pipework and fittings.

A Water Pipe Renewal Benefits Your Property

If your water supply pipe is insufficient in diameter causing reduced flow and low pressure to the property.

We use specialist installation techniques and equipment, such as pneumatic moling to minimize disruption where possible.

Prior to any excavations a full utility survey and pipe trace is completed to determine the exact location of
underground services and drainage.

Supply Pipe Repairs
In most cases, you are responsible for the maintenance of your water main past the stopcock of your water supplier. We repair leaks on all pipes and have the equipment on hand to deal with your leak quickly, with a professional fix.

All water supply pipe renewals comply with UK Water Regulations.

A septic tank is an underground chamber made from concrete, fiberglass or plastic, through which domestic wastewater (sewage) flows for basic treatment. Settling and anaerobic processes reduce solids and organics, but the treatment efficiency is only moderate (referred to as "primary treatment").

Septic tank systems are a type of simple onsite sewage facility. Septic tanks can be used in areas that are not connected to a mains sewerage system, such as rural areas. The treated liquid effluent is commonly disposed in a septic drain field or soakaways, which provides further treatment. Nonetheless, groundwater pollution may occur and can be a problem.

This is why in 2015 regulations were amended surrounding septic tanks and discharging sewage, leaving many septic tanks non-compliant. In this circumstance the problem can be easily overcome by the installation of a domestic sewage treatment plant, which replaces the outdated septic tank and is fully regulation compliant.

We are specialists when it comes to treatment plant installation and can advise on all sewage treatment systems from Septic tanks to soakaways. Please click to find out more about our work.

Sewage treatment plants eliminate contaminants from wastewater and sewage. Domestic sewage treatment systems are used when it is not possible (or legal) to install a regulation compliant septic tank.

The treatment process of the wastewater occurs as the domestic wastewater and sewage passes through the drainage pipework from the property into the sewage treatment plant. Here, the sewage treatment plant begins to break down the organic matter through its activated sludge process – which converts the sewage effluent to clean water which can be discharged to a watercourse.

Sewage treatment (or domestic wastewater treatment, municipal wastewater treatment) is a type of wastewater treatment which aims to remove contaminants from sewage. Sewage contains wastewater from households and businesses and possibly pre-treated industrial wastewater.

Physical, chemical, and biological processes are used to remove contaminants and produce treated wastewater (or treated effluent) that is safe enough for release into the environment. A by-product of sewage treatment is a semi-solid waste or slurry, called sewage sludge. The sludge has to undergo further treatment before being suitable for disposal or application to land.

The term "sewage treatment plant" is often used interchangeably with the term "wastewater treatment plant". To learn more about sewage treatment plants, click HERE
