Universal Tankers provides bulk water delivery and wastewater removal support for construction sites carrying out hydrostatic pressure testing on pipework, pipelines, pressure vessels and site infrastructure in the UK. Our service is designed for contractors, civil engineering teams and utilities projects that need a dependable water supply for a pressure test.
Hydrostatic pressure testing is used to check the structural integrity, strength and leak-tightness of a system before it is commissioned, returned to use or handed over. Reliable water supply is therefore an important part of planning the test, particularly where large pipe sections, restricted mains access or phased works are involved.
With more than 20 years in the industry, 20 depots across England and Scotland and a modern tanker fleet, Universal Tankers can support scheduled, one-off and emergency water requirements for hydrostatic pressure testing projects.
Hydrostatic testing usually involves filling pipes, pressure vessels or other pressure-containing equipment with an incompressible liquid, usually water. Engineers then use pressure pumps to raise the system to the required test pressure and monitor pressure data to identify leaks, defects, loss of pressure or potential failure points.
Water is commonly used because it contains far less stored energy than gas or air under pressure. This makes hydrostatic pressure testing a preferred pressure test method for many applications, as the risk of rapid expansion is reduced if a component were to fail or burst.
Universal Tankers can assist by delivering water before the pressure test begins and arranging collection once testing is complete. Water removal may be required where test water cannot be reused, discharged or retained on site, particularly if it contains sediment, residues or material from the system.
Universal Tankers can provide water for a wide range of hydrostatic pressure testing applications on construction, utilities and industrial sites, including:
This use-case approach allows contractors to plan hydrostatic testing around the type of pipework being tested, the length of each section, available storage and the pressure test schedule
Construction sites may need water delivered for hydrostatic pressure testing when mains supply is unavailable, restricted or unable to provide the required volume or flow. Delivered water can also support testing on remote sites, access-restricted projects and phased works where pipework is tested in sections.
Universal Tankers can provide water for a pressure test during new installation, after repairs, following system modification or before final commissioning. Deliveries can be planned around the required duration, access arrangements and storage available on site.
Universal Tankers can deliver potable and non-potable water depending on the intended use. Non-potable water may be suitable for many hydrostatic testing applications where drinking water quality is not required.
Potable water may be required where the pipework is intended for drinking water supply or where the project specifications state that water quality must meet potable standards. This may apply to potable water mains, service pipes or internal systems covered by relevant water supply requirements.

Before arranging water for hydrostatic pressure testing, contractors should determine the required fill volume, pipe length, pipe diameter, number of test sections, storage capacity and access for tanker vehicles. It is also useful to confirm whether water will be reused, discharged or collected after testing.
Where test water is being removed, the site team should consider whether it may contain sediment, residues, treatment chemicals or other material from the pipework, vessel or equipment. Universal Tankers can discuss the likely composition of the liquid and arrange collection through an appropriate disposal route.
Universal Tankers provides practical water supply and removal support for hydrostatic pressure testing across construction, civil engineering, utilities and industrial projects. Our service helps contractors arrange the water needed for large-volume testing requirements and the removal of test water once works are complete.

Universal Tankers supplies and removes water for hydrostatic pressure testing, but the pressure test itself must be performed by qualified engineers using suitable equipment, pressure pumps, monitoring equipment and test data procedures.
This depends on the pipework, pressure vessels, system specifications and intended use. Non-potable water may be suitable for many applications, while potable water will typically be required for drinking water infrastructure.
Hydrostatic testing frequency depends on the type of pressure equipment, system use, regulatory requirements, inspection regime and written scheme of examination where applicable. Some systems may be tested during installation, after repairs or at planned intervals.
Universal Tankers can collect water from pipework, tanks or temporary storage where removal is required through a suitable handling and disposal route.
Universal Tankers provides bulk water deliveries and water removal for hydrostatic pressure testing on construction, civil engineering, utilities and industrial projects. Whether you need a planned delivery, a one-off fill or urgent support for a pressure test, our team can arrange a service based on your site access, storage and volume requirements.
