Process Pipework, Pumps & Valves

Woodhams installs and modifies process pipework, pumping equipment and valves on live water and wastewater treatment works across the South of England – from a single pump replacement to a full inlet works, storm return and sludge pipework upgrade.

Process Pipework, Pumps & Valves for Water and Wastewater Sites

As a Tier 2 MEICA subcontractor, Woodhams delivers complete mechanical installation packages for Tier 1 framework partners and water companies. Our teams install and modify process pipework, pumping equipment and valves on live treatment works, with the pipe supports and access steelwork fabricated in our own workshop so the whole package is delivered by one team.

What a Woodhams pipework package covers

  • Process pipework in carbon steel, stainless steel and plastics, including high-level runs and elevated pipe racks
  • Duty/standby and variable-speed pump installation – progressive cavity, submersible and centrifugal units
  • Isolation, non-return and air valves, penstocks and flow control devices such as hydrobrakes
  • Balancing tank, storm tank and inlet works connections
  • Humus and primary settlement tank pipework and weir modifications
  • Sludge and return liquors pipework
  • Mechanical interfaces between new equipment and existing treatment assets
  • Bespoke pipe supports and access steelwork, fabricated in-house

Working on live treatment works

Almost every water site we work on stays in service while we are there. Our installation teams plan and sequence work around live process flows, temporary pumping, low-flow windows and agreed outage periods, so that treatment continuity, Flow to Full Treatment and discharge consent compliance are protected throughout. Where sites include hazardous areas, our teams are experienced in MEICA installation within ATEX zones, including sludge treatment centres.

All site staff hold NVQ and CSCS qualifications, and every package is run by a dedicated Woodhams project manager with clear weekly reporting to the client and site operations teams.

Recent Pipework, Pump & Valve Projects

Where a scheme needs it, we take responsibility from survey and condition assessment through detailed design to WIMES, workshop fabrication and site installation. Manufacturing pipe spools, supports, distribution chambers and pump skids off-site at our Rotherwick facility reduces time spent on congested live sites, cuts work at height and gives clients far greater programme certainty.

We have delivered pipework and pump packages on schemes for Southern Water, Thames Water, Wessex Water, Severn Trent and Affinity Water, working alongside Tier 1 contractors and joint ventures including 4Delivery, Galliford Try and the CMDP+ joint venture on the Southern Water AMP8 framework. See our water industry overview for the full range of MEICA services.

Pipework, Pump & Valve Installation FAQs

Do you work on live sites?

Yes. Nearly all of our water industry work is on operational treatment works; we sequence installations around flows and outages so that treatment never stops.

Can you supply the pumps and valves as well as install them?

Yes. We can procure to the client’s specification or install free-issue equipment, and we manufacture the pipework, supports and skids in-house.

What size of package do you take on?

From single pump replacements to multi-million-pound mechanical packages – recent projects range from £240k to £1.5m.

Which areas do you cover?

Hampshire, Berkshire, Dorset, Wiltshire, Surrey and across the South of England, from our base at Woodhams Business Park, Hook.
