Kapellskärsledningen (water and sewage pipeline)

Pro­ject and ob­jec­ti­ves

Ka­pell­skärs­led­ning­en is a new wa­ter and se­wage pi­pe­li­ne run­ning between Norr­täl­je and Gräd­dö via Ka­pell­skär. The pur­po­se of the pi­pe­li­ne is to re­du­ce the amount of se­wage di­schar­ged in­to the sea and to bring a drin­king wa­ter sup­ply to the port. Around 4000 pro­per­ti­es can now be con­nec­ted to the mains network, which ma­kes it pos­sib­le for ma­ny pe­op­le to con­si­der living per­ma­nent­ly in the area.

De­scrip­tion

The pro­ject in­vol­ved de­tai­led plan­ning of the wa­ter and se­wage pi­pes. The pi­pes are ma­de of plas­tic (po­ly­ethy­le­ne, al­so re­fer­red to as PE) and range in di­a­me­ter from 160 to 400 mm. Each pi­pe­li­ne is around 20 km in length. A shor­ter st­retch of pi­pe­li­ne was laid un­der­wa­ter. The pro­ject is now in its fi­nal pha­se and our re­s­pon­si­bi­li­ty is to comp­le­te the as-built docu­men­ta­tion on the ba­sis of the cont­ractor’s work.
