Bespoke pillow tank – rainwater harvesting and storage — the right choice when the project is properly scoped
This bespoke pillow tank answers a requirement for rainwater harvesting and storage. It suits private owners, tradespeople, farms and sites needing a self-sufficient water reserve that is dependable, quick to install and matched to the ground conditions.
The point that changes everything
The right tank is not the one that holds the most — it is the one that gives enough autonomy without complicating the installation.
Sizing starts from roof area, actual usage, the dry season and the space available.
What this tank actually solves
a closed reserve that limits evaporation and exposure to dirt
quick installation on level ground, with no buried rigid tank
can be connected to gutters, a pump or an irrigation network
Flocea advice: this volume suits a project constrained by dimensions, access, connections or the liquid stored.
Choose it if…
- harvesting roof water for irrigation, washdown or buffer storage
- avoiding a buried rigid tank where the works must stay simple
- installing a discreet reserve in an accessible, prepared space
Avoid it if…
- the base cannot be made level and free of sharp features
- the overflow, the filtration or the pump have not been planned
Specifications to lock down
The technical figures that prevent nasty surprises
The deciding factor is the connection layout: inlet, overflow, pump and access must be planned together. Dimensions, fittings, accessories and installation conditions are to be confirmed for your site.

Frequently asked questions before ordering
What dimensions should I allow for a bespoke tank?
The exact area depends on the format chosen and on the fittings. The base must be level, stable, free of anything that could puncture it, and accessible both for filling and for maintenance. Flocea confirms the usable dimensions before sign-off.
Can this tank be connected to a pump?
Yes, provided the outlets, valves and accessories are specified at the point of order. Tell us the flow rate you expect, so the installation is not undersized.
Does the tank arrive ready to install?
The tank is delivered folded, with the equipment listed in the quotation. Ground preparation, protection, external fittings and any pump must be planned according to the site.
Should I take this volume or the next size up?
If your need is seasonal, regulatory or awkward to replenish, allow a margin. The next size up avoids over-frequent refilling and secures your autonomy.
