Aylesford storage reservoir restoration

A complex three-year project has been completed after millions of litres of water was lost when sinkholes appeared at South East Water’s drinking water storage reservoir in Aylesford in 2020. Of the three cells on site, one was demolished, a second repaired and a third split into two, increasing turnover and efficiency. Several specialist surveys were undertaken, including CCTV, geophysical, laser scanning ground level monitoring and dynamic probing to develop repairs. Meanwhile, an alternative reservoir storage scheme was completed by repurposing an existing above ground raw water tank and a temporary water treatment works was built nearby to boost supplies.
