The ICE Awards by the Institute of Civil Engineers celebrate the achievements of people and projects in the civil engineering and infrastructure profession.

Nominations were invited for each award category, and each citation was evaluated by the ICE’s independent Awards Committee, which judges and selects the winner for each category.

The ICE president presented the winners with their awards at a ceremony at the institution’s London HQ in October.

Edmund Hambly Medal (Design for Sustainable Development)

The Award outlined the following:

When constructed in 1991, Yorkshire Water Services’ previous sewage treatment works serving the coastal resort town of Withernsea was about 180m from the cliff edge and had an expected asset life of more than 60 years. Climate change has accelerated coastal erosion. By December 2017, the site boundary was recorded as being only 56m from the cliff edge, hence the need for an urgent relocation of the facility.

Safely located 2km from the shoreline, near the village of Hollym, the replacement facility consists of a low-energy, carbon-efficient, aerated facultative lagoon treatment works. It is the largest such plant in the UK and the first on a scale that brings it within the auspices of the Reservoirs Act 1975.

It is delivering significant operational cost savings – 70% – compared with the activated-sludge plant it replaced. Constructed largely from site-won material, the plant sits unobtrusively within the landscape with minimal noise or traffic movements.

Extensive consultations with the local community were undertaken as part of the planning process. Monitoring of the new commissioned works indicates that it is meeting all of the required water quality parameters.

Operating at extraordinarily low costs, with minimal environmental impact, it provides an extremely low-carbon footprint, dramatic energy savings, no sludge production or handling, plus energy-free disinfection.
