More Southern Water work for Kier

2 days Kier has secured two more early contractor involvement contracts from Southern Water under its AMP8 strategic delivery partner framework.

Southern Water has selected Kier for £28.8m-worth of work on seven sewage works and four water supply works.

The first award, Priority Water Treatment Works Growth - Bundle 4 (wastewater), is valued at £23.5mn and covers water treatment works at Billingshurst, Dymchurch, Goddards Green, Ham Hill, Northfleet, Sidlesham and Stockbridge. 

These upgrades will enhance capacity and resilience to meet future demand and support population growth.

The second award, Nitrate Removal Schemes - Batch 1 (water) is valued at £5.3m and encompasses the water supply works at Madehurst, Patching, Mossy Bottom and Patcham. 

Kier will develop and optimise solutions to lower nitrate levels in accordance with regulatory standards, ensuring compliance with drinking water quality regulations. The early contractor involvement (ECI) phase will concentrate on design progression, constructability, and programme certainty ahead of the main construction phase.

Both contracts will be delivered under the NEC4 Engineering and Construction Contract.

The contract award comes just a few weeks after Kier was named for early-stage design and planning for nitrogen reduction works at Portswood wastewater treatment works and the installation of UV disinfection at Thornham wastewater treatment works, together worth £15.8m. [See previous report here.]

Andy Beech, framework director at Kier said: "We are pleased to secure these additional ECI contracts with Southern Water. This reflects the trust our client places in Kier to deliver projects in both clean and wastewater sectors. Our teams will bring extensive technical expertise and a collaborative approach to ensure these projects generate long-term value for Southern Water and its customers."
