This paper describes design and construction of two new sea outfalls discharging from Gullane Waste Water Treatment Works (WwTW) to Aberlady Bay, on the south side of the Forth estuary (Firth of Forth), 25km east of Edinburgh, Scotland. The outfalls were installed by float and lower, using the Flow‐Lay® technique, believed to be a first for steel pipes. The paper also describes air transport, beach movement and soil liquefaction and their effect on pipe stability, material and profile.
