Kedjehusområdet, som ligger i Fittja söder om Stockholm, byggdes 1971 och hade under flera år haft problem med stål- och kopparrör som korroderat. Rören läckte och orsakade vattenskador och höga energiförluster.Till slut blev besvären så stora att det inte gick att lösa med punktinsatser utan det krävdes att hela kulvertnätet byttes ut. Samfällighetsföreningen kontaktade Miljöentreprenören AB, som utförde arbetet.

Föreningen består av 78 kedjehus och varje hus har en egen matning. Det gamla systemet gick under husen, men det nya fick dras via entrén. ”Vägarna mellan husen är väldigt smala så det var extremt trångt att schakta, och schaktmassorna fick fraktas bort, berättar Jan Åberg, vd på Miljöentreprenören”.”Uponors Ecoflex-rör passade perfekt här eftersom det var så trångt”, fortsätter Jan Åberg. ”Vi kunde gräva igen direkt efter att röret lagts på plats. Det räckte att kopplingspunkterna var tillgängliga”.En spång lades ut till entrén till varje hus. Husägarna kunde bo kvar under hela arbetet, och dessutom ha tillgång till vatten och värme. ”Installationen gick väldigt snabbt, det stod bara öppet i två veckor. Med stålrör hade det tagit längre tid”, säger Jan Åberg.

”Vi är väldigt nöjda med Ecoflex-röret. Det är enkelt att hantera, lätt att böja och snabbt att jobba med”, fortsätter Jan Åberg. ”Vi hade bara gjort enstaka kulvertjobb tidigare, inget i den här storleken, så därför gick vi en utbildning hos Uponor Academy i Virsbo innan vi startade jobbet. Vi var faktiskt lite skeptiska till Ecoflex-röret innan utbildningen. Vi tyckte att det verkade svårt att få ihop rören, men det visade sig i verkligheten vara väldigt enkelt. Det var kanonbra att få prova systemet i Virsbo först. Vi var elva man på utbildningen, hela min firma och två grävare” berättar Jan Åberg.

”Alla är nöjda med resultatet”, säger Jan Åberg. ”Så här i efterhand var det perfekt att det gamla systemet byttes ut under 2009 med tanke på den extrema vinter som följde”.Även de boende instämmer. ”Vi känner förtroende för det jobb som är gjort. Vi kunde behålla det gamla systemet medan det nya lades, och vi behövde inte vara utan vatten. Det var intressant att se hur arbetet utfördes, gata för gata med de långa rörlängderna”, säger Lars-Ivan Alsiö från Stökhagen Samfällighetsförening.
