A complete system designed for the use of rainwater in the garden with capacities of 1000l, 2500l, 3500l
Bolt tanks are characterised by their high durability and resistance to external conditions. The tank is buried in the ground and the only visible part of the tank on the ground surface is the cover installed on the inspection manhole. Underground rainwater tank. Marseplast's BOLT is made of linear polyethylene, using the rotational moulding method, which guarantees its durability and strength. However, it must be remembered that the tank should be properly sited. The subsequent steps of its assembly must be carried out in the correct order. The assembly instructions can be found in the download section.
The maximum ground surface is 40 cm; if the tank installation depth needs to be increased, reinforced concrete slabs must be installed above the tank. The slab is designed by the constructor according to the conditions on the site.
Tank equipped with a filter
NOTE:
Two superstructures are dedicated to the 1 000 l tank depending on the diameter of the manhole. To increase the height of the manhole at the inlet (manhole 270 mm), the SR Eko superstructure is dedicated (two heights to choose from, 21 cm and 35 cm). For a larger manhole (440 mm), choose the Bolt Standard superstructure.
For tank capacities from 2,500 l to 3,500 l, the Bolt Standard superstructure is the right choice: Bolt Standard superstructure

Water intake:
Selectable water intake type:
External intake - garden box for garden hose connection. Included is a ¾ GZ ball valve and a ¾"-1" GZ PE elbow screwed into the ball valve from below. Top diameter of the box - 210 mm, bottom diameter of the box - 180 mm, height of the box - 120 mm.
The second variant is the water intake directly mounted in a special rain cover. There is an additional inspection hole for the intake. The hose is terminated with an Aqua Stop quick-release coupling. This system works so that if the hose is unhooked, the water supply is disconnected automatically.
Delivery hose for connecting the pump with the garden box
3.2 metre discharge hose for connecting the pump to the water intake - resistant to 5 atmospheres for the garden box.
The hose is 3 m long when integrated into the intake cover. It is terminated with a quick-release coupling and threaded connection.
Multi IP 1000 Auto submersible pump
Submersible pump Lift 45 Auto
Submersible pump Lift 35 Auto
High-performance submersible, pressure pump. Ideally suited for garden irrigation or sanitary purposes. Integrated pressure switch with flow sensor automatically switches the pump on/off as required. The integrated "dry run" protection protects the pump from damage by stopping operation if the water level is too low. The pump is equipped with a carrying handle and power cable. Adapted for use with a flexible hose.
Automatic submersible pump that requires no additional accessories. Integrated pressure switch with flow sensor automatically switches the pump on/off as required. The integrated dry-running protection protects the pump from damage by stopping operation if the water level is too low. The pump is equipped with a convenient carrying handle and power cable. Adapted for use with a flexible discharge hose.
Depending on availability, the set is supplied with a Multi IP 1000 Auto pump, a Lift 45 Auto pump or a Lift 35 Auto pump. All these pumps are of high quality and are successful replacements.

This short guide will help you choose the right capacity for your underground rainwater storage tank - without difficult formulas. We will show you how to estimate your needs, count the amount of water from your roof, select the capacity and plan a simple garden installation.
Step 1: Determine what you will use the rainwater for.
List the uses: watering the garden, flushing toilets, laundry, washing the car, housework. This will allow you to estimate the real need for water in a typical week.
Garden watering - take a guideline of 20-25 l/m² per month per season.
Toilet flushing - approximately 35-50 l/person/day.
Laundry - approx. 15-20 l/person/day.
It is advisable to select a tank for 2-3 weeks of typical use - in practice there is no point in storing 'for the whole year'.
Step 2: How much water you collect from the roof (no complicated formulas)
In simple terms, assume: annual rainfall × roof area × runoff coefficient. For most roofs, you can assume a coefficient of around 0.9 (depending on the roofing and the layout of the gutters).
Brief example: calculation of possible rainwater yield
Roof 120 m², annual rainfall ~600mm (approx. 600 l/m²). Estimate: 120 × 600 × 0.8 ≈ 57,600 l/year. This figure helps to select the capacity for a period without rain. And a period without rain can last for 3 weeks. Therefore, you must divide the result by 21 days. That is: (57600 l /365 days)*21 days = 3314 l, the result according to the estimation should be taken as a minimum. Therefore then we choose 4000l , 5000l, 6000l tanks - because of how we will use the rainwater.
Step 3: Selecting the tank capacity
It is most practical to select a tank that will store a supply of water for 2-3 weeks of your needs.
How to calculate capacity: annual rainfall × roof area × runoff coefficient ≈ annual amount of rainwater to be collected.
2000-3000 l - small garden, 1-2 people.
4000-6000 l - family of 3-4 people + garden 200-300 m².
8000-10 000 l - larger garden, intensive watering. 300 m² - more , and with automatic watering.
But you will do this more precisely using the selection calculator below:
In detached houses, underground rainwater tanks are the best choice - they do not take up space in the garden, provide stable temperatures, no water freezing and allow larger capacities without affecting aesthetics.
The best material is PE, HDPE, MDPE plastic - it is lightweight, corrosion resistant, easier to install and above all airtight for many years . It is worth paying attention to water and ground conditions. If the ground water level is high or the soil is clayey, flat tanks such as the F line, Bolt, Eco line Slim, etc., are the best choice. On the other hand, if the conditions are normal, any solution can be used. If you have any problems, please contact our customer service.
Step 5: Simple installation in the garden
The simplest arrangement: gully filter in front of the tank or basket filter, underground tank, floating intake, automatic pump and point of use (tap). This makes watering convenient and economical.
Summary:
Estimate the weekly consumption (garden + house).
Calculate the roof potential (rainfall × area × ~0.9) and divide by 365 days and multiply by 21 days ( 2-3 weeks of drought).
Select an underground storage tank taking into account the yield (calculated from the roof area) and contrast it with the consumption e.g.: water in the garden. Select capacity
For example: family of 3-4 people + garden of 80-150 m² → 4000-6000 l usually works well. Larger garden / intensive watering → 8000-10 000 l. Verify with the calculator above.
Is it possible to supply toilets with rainwater?
Yes - using a suitable system (rainwater control unit/automatic switchover) and filtration.
What about excess water?
Plan an overflow to an infiltration or rainwater drain in accordance with local regulations.
