All Pumps’ range of Aquaflo modular, underground water storage systems are made from robust, high-density polyethylene (HDPE) with storage capacities of 5,000L to 30,000L (or larger on request).
Aquaflo’s modular design makes for almost unlimited configurations, suited to all types of ground installations. These underground water storage tanks are easily transportable and will withstand water pressure at depth, are easy to install with a one piece design. Depending on your application, Aquaflo underground water storage tanks can be connected in series and combinations to suit your storage needs, making them popular for water reuse and harvesting applications, water detention tanks, sewage pump stations and emergency sewage storage applications.

Only qualified personnel should install, operate and repair your Aquaflo Storage System. Any wiring of pumps or similar electrical equipment should only be performed by a qualified electrician. All specifications must be certified by the engineers/consultants and relative governing authorities before commencement of construction and installation.
The customer or installer is responsible for ensuring that the installation of this Aquaflo Storage System is in compliance with any regulatory requirements of the planning authorities, building control, Environmental Agency, Water Board and/ or National (AS/NZ) Standards. If ground water is likely to be present within the excavation, make sure all details for the correct installation procedure are followed – If in doubt, -contact the Engineers Department.
The contractor is responsible for the off-loading of the tank. The tank must be handled with care to prevent accidental damage from impact or contact with sharp objects.
The tanks should be lifted using slings, not chains or wire ropes. For tanks longer than 5 metres, use a spreader bar or have the slings apart at least ¼ of the tank length. Do not drag the tank along the ground for any distance and avoid jarring or bumps. Do not lift with water in the tank.
|Site Access and Controls|
|It is the responsibility of the client or installer to ensure suitable access to good hard ground conditions that are safe and suitable for off loading the Aquaflo Storage System.|
|Set the tank on smooth level ground, free from bricks and/or sharp objects. Chock/tie down to prevent the tank moving during high winds.|
|Where tanks are of such size that police or private escort is required, delivery times given are only estimates. In the event of a delay outside our control, if any extra charges arise, they will be forwarded to the contractor.|
Determine the best location for your Aquaflo Storage System and pump controls (If applicable). These recommendations indicate the requirements for installation in the typical site conditions. The installer should ensure that the requirements for their particular site conditions and anticipated loadings are met, taking engineers' advice where necessary. Before installation of the Aquaflo Storage System, check ground conditions and inlet pipe invert levels, as this will determine the tank depth and construction.Before digging, call the relevant authorities to locate any underground lines or cables.The installation of the Aquaflo Storage System may require the prior approval of the local council.Questions relating to this should be directed to a responsible officer of the local council and/or relevant authorities. Aquaflo Storage Systems, regret they are not able to supply this information.Check tank for any damage that may have occurred during freight or handling. Be careful to avoid any “bruising”, as all damage must be repaired before installation, Refer to supplier. Please tighten all fasteners and associated equipment before installation.
Aquaflo Storage Systems should be vented in accordance with the current applicable plumbing and drainage standards. In multiple chamber tanks, venting must not be combined into a common stack below a point where pollutants contained could be transferred to other chambers.
The granular backfill is for the entire tank excavation, terminating level with the top of the barrel of the tank, and the remaining backfill from top of tank barrel to ground level/underside of concrete slab may be the approved back fill, excavated material or selected clean backfill material. It maybe necessary to line the excavation with Geofab (Filter Fabric) class A24 to separate the approved backfill from any unstable latent soil conditions – If unsure check with the Engineering Department. The correct backfill medium is one of the critical factors in the successful installation of an in ground horizontal polyethylene Aquaflo Storage System tank.We insist on backfill compliance prior to starting any installation works. Confirm with your supplier in advance that your backfill will meet or exceed the following:
The correct appraisal of site conditions is essential before installation of the Aquaflo Storage System. The installer must recognise that these systems when empty will float on approximately 50 mm of water. The upward thrust at the base of the tank, when fully immersed in water could exceed 69 000 KPA.
If there is any likelihood of water ingress to the ground where the tank is to be buried – e.g.: Tidal conditions, saturated ground, during heavy rain and/or flooding or run-off water from other sources. Pay particular attention to the drainage of the tank excavation.
Where tanks are installed under adverse site conditions, the utmost care is required to prevent any chance of the tank being forced out of the ground by upward pressure of water. This can occur if the excavation base is not properly drained.
For installations where water table conditions are above the tank, it is recommended that the tank be held in the ground with either concrete or an anchoring system – See Engineers' Department for more details and calculations.Where excavations width and/or depth are an issue, install shoring to meet the relevant National Standards.These notes should be read together with the following recommended installation details drawings shown in 12 Easy Steps.
