Underground Oval Water Tanks
There are very many ways of collecting rainwater off a structure, the main component of the system which at the same time defines it is the water tank that can be either surface or underground, the accelerating reason for the adoption of which method to use has however been three fold: the cost, the system durability and the area available to have such a required size; any system that can meet this criterion satisfies the end user.
Unlike other tank designs, the amazing SIRACO Egg tank has been proven to meet this, increasing the durability by over 60% while reducing the cost by over 65% comparatively. With all the best attributes of this technology which should have instead called for a higher price, you can get a gigantic permanent 100,000litres at a comparatively much less cost depending on site soil profile, this capacity that fills with in 4-10days of rains under a reasonable roof, is enough to sustain over 50people at homes, over 120pupils/students at school, and an 8x15m (120sqm) greenhouse for 3dry months, which in most cases is the estimated dry period; making a smooth transition through challenging seasons.
The tanks take up an egg shape, the most stable and strong shape with low surface area requirement, a reason they can be suitably installed underneath the driveways, paved compounds, parking lots, backyards, school compounds, poultry farms, irrigated farms and any other places where water is essential yet with limited space.
Other tank designs like; ferroconcrete tanks; box or cylindrical shaped are expensive and easily develop cracks, giving the oval type a cutting edge. Aware of the dirt on the roof for those next to roads/streets and in general after a dry spell, the tank can be fitted with our ‘first flush device’ technology to flush the first rain water that washes the dirty roof for about first five (5) minutes, and later allows the clean water into the tank; this makes it suitable for many clean water-requiring purposes. The tanks can also be used for Runoff Farming, thus boosting food security and production in dry areas.
