Quote: rainwater collection and storage
E.g.: underground tank, above-ground water butt
First identify the outlets you want to supply and the roofs available for collection. Add a plan of downpipes, proposed location and access. A garden reserve and a system serving the house need clearly distinct proposals; do not choose storage volume solely from household size.
Describe collection and storage
Provide roof area, material, relevant downpipes and proposed location. Request a volume recommendation with its assumptions and explain what happens when storage is empty or full. Compare options for the site without assuming an underground tank is always necessary.
Check local usage precautions
The AGE/Health guide excludes food-related use and personal washing, places conditions on uses including laundry and requires permanent physical network separation. A check valve alone is insufficient. Have each intended use assessed against the guide.
Prepare the location
The survey should specify machinery access, existing utilities, installation conditions, lid and surfaces to restore. Ask where overflow will go and what procedures that destination requires. Identify accessible maintenance equipment rather than treating the tank as the entire project.
Arrange handover and upkeep
Request system diagrams, references, manuals, tests and instructions for faults or empty storage. Allocate professional checks and your own tasks clearly. Agree equipment-specific upkeep rather than a universal schedule claimed to suit every tank.
Indicative prices in Luxembourg
On quotation
Compare a complete installation: tank, collection, possible excavation, distribution, controls and reinstatement. Offers should specify the same uses and quantities. Separate investment, operating expenses and possible aid; do not subtract an assumed grant from the quoted price.
Subsidies and grants
No grant is deducted from the budget shown here. If a quote mentions support, request the exact scheme and confirmation of your eligibility before including it in financing.
Frequently asked questions
What tank size suits a house?
Request calculations and assumptions for your collection and uses rather than a generic size range.
Must the tank be buried?
Compare solutions compatible with the location and agreed scope.
Can it serve a washing machine?
Have this use assessed against the cited official guide’s precautions before including it.
What happens when storage is empty?
The proposal and manual should describe the intended operation and associated equipment.
