Harlequin Underground Home Harvest Direct Tank 1500 Kit
When supply of rainwater is exhausted, the 'backup in a box' unit uses mains water to replenish the tank. The pump in the tank is then ensured of a constant supply of water to feed washing machines, toilets, garden taps, etc. Harlequinl’s ‘HydroStore’ tanks benefit from the company’s experience in providing tanks for underground installation as well as recognising the engineering progress being made in the global rainwater harvesting sector.
The HydroStore allows full capacity storage and when installed above the natural water table, does not require a concrete surround.
The lower part of the body has vertical flats which allow interconnecting pipework and the linking together of multiple tanks to provide greater storage capacities. The HydroStore has been designed to minimise materials and installation costs. The base of the tank is flat which helps with installation and allows complete drainage of the tank when cleaning. The cover is retained using a single bolt and can be removed completely to leave clear access. Surface water is directed down past the lid and turret to soak away into the surrounding soil. Ultimately, these tanks become air pockets under the ground, allowing their volume to be flooded with recovered and usable water. Above ground they do not impede on available space which can be used for more diverse, practical and imaginative purposes. Modular design - Allows increased capacity by linking together multiple tanks. Large diameter flat load-bearing lid for easy access, unobtrusive to pedestrians, lawnmowers, etc. Turret - Diverts potentially contaminated surface water away to preserve integrity of captured water. 500mm invert depth as standard, with collars available to enable adaptation to site conditions. Inlet - Calmed inlet reduces turbulence to tank sediment, improving water quality to property. Filter - Self-cleaning, low maintenance filters, with no consumable parts, at inlet and pump ensure clear water supply. Tank body - Seamless, one-piece moulding eliminates on-site ‘assembly’ and guarantees internal cleanliness. Flat base for stability and integrated lifting points for ease during handling and installation. Entire capacity utilised, ie, no potential air pockets or base ribs to reduce ‘working’ volume. Pump - Pressure-sensitive (turns off if no demand), dry-run protected (turns off if no water detected) pump for extended service life. Pump outlet capable of delivering 2500ltr/hour, nominal 35m head, and 3.5 bar pressure to guarantee reliable, constant and efficient supply. Shallow excavation + no concrete backfill = reduced installation costs.
The installation of the HydroStore couldn’t be easier or more cost effective. The overall design of the tank is aimed at reducing costs from delivery to installation and from day-to-day use to annual maintenance. The HydroStore is designed to allow two people - using the most basic digging equipment, ie, a couple of shovels -to move and install a system. Another key benefit of the tanks’ low height is that no concrete backfill is required as long as the water table does not rise above the base of the tank.
Water table considerations
Even if no water table exists, if the complete surrounding soil structure is non porous, eg, clay, a danger exists of water pooling around the tank within the backfill. In this circumstance either a land drain should be installed to
continually drain the installation or an alternate location selected.
