Why Cisterna Pronta

Engineering that delivers water autonomy

100% automated

With the entire pumping (delivery) system, automation and protections factory-installed, everything runs autonomously.

Real savings

Cut potable water consumption and bills by up to 70%, with fast, measurable payback.

Plug'n'play installation

Pre-sized by our specialists, installation is quick and practical, leaving the system ready to use in less than 24 hours.

No pump room needed

Receive a single unit with the entire filtration, pumping and automation system factory-installed — and don't waste time and money on external infrastructure.

No civil works

Designed to withstand soil loads, it can be buried in the garden without any civil works, fully plug'n'play — above-ground options are also available.

On your property

How Cisterna Pronta works

The water's path step by step — and note: filtration, storage and pumping all happen inside the unit itself, not in separate equipment.

      Multiple applications

      Where Cisterna Pronta comes into play

      A versatile technology designed for stormwater management — an engineering answer to every requirement of your project.

      Rainwater harvesting

      Rainwater collection, filtration and supply for non-potable uses — from the roof to the point of use.

      Stormwater retention and detention

      Sized to retain and detain stormwater in line with drainage legislation, releasing the flow to the public network in a controlled way.

      Irrigation water management

      The stored water supplies gardens, landscaping and irrigation — non-potable reuse with up to 70% savings.

      Non-potable reuse

      Supplies toilet flushing, floor cleaning and common areas, reducing the building's potable water consumption.

      Step by step

      Quick and easy installation

      Click each number on the drawing to see the stage — from preparing the trench to backfilling. The exact dimensions of each model are in the product manual.

      Stage 01

      Digging the trench

      Dig/excavate the trench to the dimensions given in the product manual.

      Stage 02

      Preparing the bedding

      Prepare the bedding with 20 cm of No. 1 crushed stone and 20 cm of coarse sand, forming a firm, level base.

      Stage 03

      Placement and anchoring

      Place the tank in the trench and anchor it if necessary, ensuring the inlets and outlets are aligned.

      Stage 04

      Partial backfill

      Add sand up to half the tank's height, surrounding it evenly.

      Stage 05

      Filling

      Fill 50% of the tank's volume with water to balance pressures during backfilling.

      Stage 06

      Inlet and outlet

      Connect the system's inlet and outlet piping according to the hydraulic design.

      Stage 07

      Consumption, delivery and power

      Connect the consumption/delivery piping and the power supply for the automated system.

      Stage 08

      Backfill and landscaping

      Complete the final backfill and landscaping — the system stays buried and invisible in the garden.

      Frequently asked questions

      Everything you need to know about Cisterna Pronta

      What is Cisterna Pronta?
      It is a prefabricated FRP cistern, sized to your rainwater harvesting needs, 100% automated and tailored to your project. It is fully engineered for underground installation without any civil works — above-ground versions are also available.
      How does rainwater harvesting work?
      Rainwater is collected from the roof, sent to the filter (included in the standard kit) and then to storage via up-flow filling. A 100% automated delivery pumping system (included in the standard kit) supplies every point of use according to your design.
      How can Cisterna Pronta be used for stormwater retention/detention?
      Based on your design, we size and manufacture the system, adapting it to meet all applicable local regulations, handling stormwater retention and system operation according to the engineering planned for your project.
      Is water filtration included? Do I need to clean the filter?
      Yes, the water filtration system is included in the Cisterna Pronta kit. And because it was designed for your convenience, our system is 100% self-cleaning — it requires no cleaning or maintenance routine to perform.
      Do I need to build a pump room or buy separate items?
      No! Everything you need for excellent-quality water comes from the factory, so no pump room or separate items are required for the system to work. If your project has specific needs, talk to our specialists.
