Project Details Kingston Outfall
Project started in June 2004 The first 1,200 ft of pipe was installed on the beach with conventional land equipment from behind the Kingston Marina out to the zero tide mark. The next 500 ft was laid and backfilled one joint at a time during high tides from a derrick barge offshore. The next 2,200 ft was installed and backfilled in a pre-excavated 6-9 ft ditch in 96 ft sections. The ditch was backfilled first with gravel and quarry spalls, then native material previously removed. The final 1,400 ft was laid directly on the bottom out to a set of diffusers at -170 MLLW. All underwater connections were made with divers. At the outer end of the outfall a four-diver crew was required, with each diver only having 14 minutes of bottom time due to the depth.
