The NEPTUN underground tanks represent well-proven method of rain- and waste water management. They are made of high-quality polyethylene by rotational moulding method and available in volumes of 6, 10, 14, 18 and 22 thousand litres. When being installed underground, they do not require to be embedded in concrete, which significantly reduces installation costs. They can be installed in sand, gravel and clay, also below the groundwater table. All tanks are fully self-supporting and their ribbed design provides exceptional strength.

Water price is constantly increasing nowadays. Using rainwater is a significant method of reducing running costs of family houses and recreational buildings. It can be used for garden watering, car washing, toilet flushing or clothes washing (the utility water and the drinking water distribution systems are separated). You can save up to 50% of household water consumption. On top of that, the rainwater is "soft", therefore it does not cause lime-scale on the piping and equipment and also reduces detergent consumption.
Drainless tanks with lockable lid on the inlet opening are used for collection of waste water, which is later collected and disposed by municipal sewage treatment plants.
