WATER STORAGE SOLUTIONS

NO WATER? NO PROBLEM! SIMPLY CHOOSE THE SYSTEM THAT BEST WORKS FOR YOU

01

RAINWATER HARVESTING 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.

•

Store rainwater accessed from roof

•

Rainwater filtered prior to entering tank

•

Water suitable for irrigation, washing, topping up the pool etc.

MUNICIPAL BACK UP 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.

03

Uninterrupted water supply

• •

Tank filled with municipal water

•

Pressure sensor starts and stops pump operation

Pump from tank back into mains

•

Water fit for consumption

FULLY INTEGRATED 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. •

Combination of both Municipal Back Up & Rainwater Harvesting

•

Ensures water is always available

•

Tank filled with municipal water (pre-determined min. level required) and rainwater (remaining space)

REQUIREMENTS

USES

RAINWATER HARVESTING FOR A BASIC SYSTEM YOU WILL REQUIRE THE FOLLOWING:

1

TANK

5

ELBOW - 110 mm

Standard tank fittings (inlet/overflow and outlet) are included in the price.

6

TAP - 20 mm

2

BASE/PLINTH

3

PRE-FILTRATION 3a. 3b. 3c.

4

Mesh/Tank Screen - beneath lid Rainhead i.e. Leaf Eater First Flush Diverter

Purchase separately from dealer and an additional 40/20 reducer is then also required to fit it onto the tank. Note: This is an example of a basic Rainwater Harvesting installation. Each installation will vary based on the setup and personal preference.

PIPES - 3 x 110 mm SV pipes Lengths will vary depending on installation. 4a.

From bottom of T-junction to slow release control valve.

4b.

From side of T-junction to the elbow.

4c.

From elbow through lid into the tank.

THE BENEFITS 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.

SYSTEM COMPONENTS

How to estimate what size tank would be sufficient for Rainwater Harvesting: Roof p/m² 50 - 100 200 - 400

Tank Size 750 L - 2200 L 2500 L - 10 000 L

The biggest downfall of Rainwater Harvesting is lack of storage capacity.

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

BASE/FOUNDATION OPTIONS Tanks 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 Base 750 L 760 mm 860 mm 1500 L 1410 mm 1510 mm 2200 L 1420 mm 1520 mm 2500 L 1420 mm 1520 mm 5000 L 1820 mm 1920 mm 10 000 L 2200 mm 2300 mm

01

1. BASE/CONCRETE PLINTH

CHOOSE A TANK

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).

4. FIRST FLUSH DIVERTER

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.

RAINWATER HARVESTING

Cut a hole of 110.5mm in the middle of the lid and fit the pipe through the hole, stopping before the mesh/tank screen.

3. TANK SCREEN/ LEAF EATER a. b.

Ensure the tank screen is fitted beneath the lid of the tank. Fit the leaf eater to the downpipe vertically or horizontally).

6. RECOMMENDATION

2. SELECT PRE-FILTRATION 5. CUT A HOLE IN THE TANK LID

Select desired pre-filtration options. Pre-filtration will differ depending on preference and what the water will be used for.

Install an additional elbow and pipe to the overflow, and route to a suitable/required area to ensure no water goes to waste.

4

PIPES - 3 X 110 mm SV pipes Assumed ¾ inch galvanized pipes 4a.

25 mm diameter (minimum) - from tank to gate valve, to pump.

4b.

20 mm diameter (minimum) - from pump to house, to cut into mains.

4c.

Supply tank with municipal feed to float valve at the top of tank.

ELBOWS Sizes according to pipes

Standard tank fittings (inlet/overflow and outlet) are included in the price.

6

GATE VALVES To isolate components and manage the system.

7

NON-RETURN VALVES

8

FLOAT VALVE To control the fill height of the tank. 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.

THE BENEFITS 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).

SYSTEM COMPONENTS

CHOOSE A TANK How to estimate what size tank would be sufficient for Municipal Back Up: 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 required i.e. 4 x people (600L) X 3 days = 1800L

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

INSTALLATION

1. BASE/CONCRETE PLINTH

PRE-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).

Tanks 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.

02

4. SUPPLY TANK WITH WATER

BASE/FOUNDATION OPTIONS

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.

MUNICIPAL BACK UP

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

3. PLUMBING - PUMP TO HOUSE a. b.

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

6. RECOMMENDATION

2. PLUMBING - TANK TO PUMP 5. FILL THE TANK

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

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

FILTER/STERILISATION To improve the quality of water used from the tank. The water needs to be filtered and sterilised as it is utilised for full domestic supply. 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.

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.
