WATER STORAGE SOLUTIONS

NO WATER? NO PROBLEM!

The installation of a tank that is filled automatically when mains water is available. This water can then be utilised in the event of a cut-off from mains supply.

The installation of a tank that is filled with both Rainwater and Municipal water. This water is filtered/sterilised and utilised for full domestic water supply.

The installation of a tank that is filled automatically when it rains. This will require the installation of suitable guttering and piping to transport rainwater to the tank.

It is simple, easy and offers advantages like self-sufficiency and the convenience of not being dependent on regulated water resources.

It presents the opportunity to replace high quality drinking water with Rainwater, for low grade uses such as toilet flushing, irrigation, household cleaning and car washing. As a result you will save water, reduce your water bill and have access to an adequate water supply when none is available.

THE BENEFITS

FOR A BASIC SYSTEM YOU WILL REQUIRE THE FOLLOWING:

SYSTEM COMPONENTS

CHOOSE A TANKHow to estimate what size tank would be sufficient for Rainwater Harvesting:

Roof p/m² Tank Size50 - 100 750 L - 2200 L200 - 400 2500 L - 10 000 L The biggest downfall of Rainwater Harvesting is lack of storage capacity.

TANK PLACEMENTShould preferably be at a downpipe, or alternatively be repositioned by use of proper piping/guttering.

BASE/FOUNDATION OPTIONSTanks must be installed on a sound, level and smooth surface. Level paving will suffice, or a properly designed tank stand. Alternatively a concrete plinth needs to be built, ideally with a concrete surface bed at least 85mm thick.

Recommended base sizes are:

Tank Diameter Base750 L 760 mm 860 mm1500 L 1410 mm 1510 mm2200 L 1420 mm 1520 mm2500 L 1420 mm 1520 mm5000 L 1820 mm 1920 mm10 000 L 2200 mm 2300 mm

PRE-INSTALLATION INSTALLATION

Ensure tank is installed on a suitable base. The base must be sound, level, smooth, free of any protrusions and at least 100mm wider than the base of the tank (refer to pre-installation).

Install the first flush diverter as per instructions provided inside packaging. Note: the first flush utilizes a dependable ball & seal system, requiring no manual intervention.

Municipal Back Up offers you a pressured water feed solution, providing you with an uninterrupted water supply at all times.

The best way to avoid the inconvenience of water interruptions is by installing a Municipal Back Up system. This offers you a chance to reduce your reliance on regulated water, with the added bonus that you still have access to clean water and no additional filtration is needed (like rainwater harvesting).

THE BENEFITS

Note: This is an example of a basic Municipal Back Up installation. Each installation will vary based on the setup and personal preference.

It is advised to make use of a plumber/professional installer as it is required to tie into the buildings main water supply line.

FOR A BASIC SYSTEM YOU WILL REQUIRE THE FOLLOWING:

People 1 2 3 4 5 Litres p/day 150 300 450 600 750 Size of tank = litres p/day X total days back up requiredi.e. 4 x people (600L) X 3 days = 1800L

TANK PLACEMENTShould be placed where municipal supply can be intercepted, before entering the house.

BASE/FOUNDATION OPTIONSTanks must be installed on a sound,level and smooth surface. Level paving will suffice, or a properlydesigned tank stand. Alternativelya concrete plinth needs to be built,ideally with a concrete surface bed atleast 85mm thick.

PRE-INSTALLATION INSTALLATION

Ensure tank is installed on a suitable base. The base must be sound, level, smooth, free of any protrusions and at least 100mm wider than the base of the tank (refer to pre-installation).

Supply the tank with municipal feed to float valve at the top of the tank. When full, the float valve will close the water supply and when it drops it will open and allow the tank to be filled.

Use minimum of 25mm diameter pipe from the tank, to the gate valve, to the pump.Connect the pump to the electrical main supply.

Ensure that the gate valve is open and fill the tank from municipal supply.

a. Use minimum 20mm pipe from pump to cut into mains (where possible), before PRV valve.b. Install a non-return valve (between house and mains) to ensure no back pressure to mains.

It is recommended that the water is run once every two weeks to rotate the water and ensure system functions properly.

A Fully Integrated System provides you with Municipal Back Up, and the additional benefit of harvesting Rainwater (which is free and makes this system cost effective).

A Fully Integrated System is a combination of both Rainwater Harvesting and Municipal Back Up. It provides you the benefit of reducing your reliance on regulated water (municipal back up), as well as saving water (rainwater harvesting), and still gives you access to an adequate water supply when there is none.

THE BENEFITS

Note: Each installation will vary based on the setup and personal preference.

It is advised to make use of a plumber/professional installer as it is required to tie into the buildings main water supply line.
