01 / Water & civil engineering

01 / Bromley, Kent

Shortland’s WBS

Civil works for a live water treatment works and booster station.

Client: MWH Treatment
Contract value: £1.4m
Completion: March 2026

Project context

The site produces 11 Mld of treated water and pumps approximately 45 Mld from Bickley and Bromley towards Farnborough Reservoir. MWH Treatment’s upgrade replaced pumps, motors, pipework, manifolds and electrical infrastructure while maintaining deployable output.

Our scope

Early Contractor Involvement, trial holes and review of the outline design against site constraints.
Ducting and draw pits, slabs for LVDB and MCC equipment, the temporary booster station and generator bund.
A retaining wall, a new 5 m deep blind tank and delivery bay.
A 600 mm DI manifold and associated pipework approximately 4 m deep.

DELIVERY HIGHLIGHTS

Delivered on time and under budget. The project won an MWH Treatment Excellence Award. The presentation also records an APM award shortlisting for October 2026.

Completed sheet-pile, drainage and reinstatement works at Stoke Newington.

02 / Hackney, London

Stoke Newington Reservoir

Reservoir repairs shaped around a constrained residential setting.

Client: MWH Treatment
Contract value: £2.1m
Completion: December 2025

Project context

A Thames Water willow-stick survey identified leakage paths along 400 m of the reservoir. Further investigations found signs of slippage in the same area, with a regulatory programme date defining the delivery window.

Our scope

Constructability review with MWH Treatment, considering environmental impact and disruption to the local community.
A revised solution with herringbone drains more than 1 m deep.
A new 400 mm high capping beam following 400 m of sheet-pile installation.
Public footpath reinstatement and relandscaping.

DELIVERY HIGHLIGHTS

The project won an Excellence Award and was shortlisted for the Water Industry Awards.

Completion: May 2023

Project context

Walton Water Treatment Works supplies approximately 250 Mld. MWH Treatment’s programme removed existing infrastructure and introduced surge vessels, motors, pumps and MCC equipment.

Our scope

Review of draft For Construction drawings and collaborative constructability workshops.
Slabs for two free-issued surge vessels.
Multiple legs of 450 mm pipework approximately 3 m deep.
Ducting, draw pits and slabs for the new MCC, including temporary works for connections to existing infrastructure.

DELIVERY HIGHLIGHTS

Delivered efficiently, on time and under budget. MWH Treatment subsequently allocated the Walton Calm and Cross Connection project.

Reprofiled embankment and new footpath at Maiden Lane.

Maiden Lane Reservoir Stabilisation

Embankment stabilisation beside a playground, park and residential properties.

Client: MWH Treatment
Contract value: £1.5m
Completion: September 2022

Project context

Following evidence of slippage on the eastern embankment, MWH Treatment and Mott MacDonald developed a stabilisation scheme. The location required a detailed delivery sequence within a limited working area.

Our scope

Scope review and a coordinated delivery sequence for the constrained site.
Two piling platforms for 50 CFA piles at 12 m and 10 m depth.
Drainage blankets, channels, storage crates and manholes at different reservoir levels.
Reprofiling and new footpaths to British Standards.

DELIVERY HIGHLIGHTS
