BlueLine II tank

Underground tank for rainwater or sewage by Rewatec

BlueLine II is an underground, polyethylene tank from Rewatec for collecting rainwater. The tank is also suitable as a tank for municipal waste water or for chemically aggressive waste water. BlueLine II is made from environmentally friendly polyethylene (PE - MDPE) using the rotational moulding method, or rotomoulding. Due to its monolithic construction (one piece, no joints or welding), the tank is extremely strong and stable. It is possible to fill the tank with soil up to 1.5 m (above ground). Manufacturer's tests confirm the 100% tightness of the tank - warranty 25 years.

Every Rewatec underground rainwater tank (our offer includes the BlackLine tank) is subjected to intensive quality control after production. In addition, the tanks are subjected to a pressure test using complex and extreme loads simulating the conditions found in the ground.

 We also offer complete sets for using rainwater in the garden: GARDEN SYSTEM STANDARD BLUELINE II.
