Municipal Back UpThe 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.

• Uninterrupted water supply• Tank filled with municipal water• Pump from tank back into mains• Pressure sensor starts and stops pump operation• Water fit for consumption

Rainwater HarvestingThe 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.

• Free & unlimited water supply (when it rains)• Store rainwater accessed from roof • Rainwater filtered prior to entering tank• Water suitable for irrigation, washing, topping up the pool etc.

Fully IntegratedThe 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)

FOR A BASIC SYSTEM YOU WILL REQUIRE THE FOLLOWING: SYSTEM COMPONENTS

1. Tank

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

2. Base/Plinth

3. Pre-Filtration

3a. Mesh/Tank Screen - beneath lid3b. Rainhead i.e. Leaf Eater3c. First Flush Diverter

4. Pipes - 3 x 110mm 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.

5. Elbow - 110 mm

6. Tap - 20 mm

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 setupand personal preference.

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.

1. Base/concrete plinth

4. First flush diverter

2. Select pre-filtration

5. Cut a hole in the tank lid

3. Tank screen/ leaf eater

6. Recommendation

PRE-INSTALLATION

1. 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.

2. Tank placementShould preferably be at a downpipe, or alternatively be repositioned by use of proper piping/guttering.

3. 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:

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.

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

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.

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

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

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

2. Base/plinth

3. Pump

4. Pipes Assumed 3/4 inch galvanized pipes4a. 25 mm diameter (minimum) - from tank to gate valve, to pump.4b. 20 mm diameter (minimum) - from pump to house, to tie into mains. 4c. Supply tank with municipal feed to float valve at the top of tank.

5. ElbowsSizes according to pipes

6. Gate valvesTo isolate components and manage the system.

7. Non-return valves

8. Float valveTo 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.

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

www.jojo.co.za

Float valve can be ordered separately and purchased from dealer.

Install gate valve as close to tank as possible.

Rule of Thumb:the larger the distance

is between the pump and the house, the larger

the pipe must be to ensurethat there is enough

pressure when the waterreaches the house

Install non-returnvalve to ensure noback pressure to municipal supply.

Gate valve to beinstalled inline in caseof float valve failure.

INSTALLATION

1. Base/concrete plinth

4. Supply tank with water

2. Plumbing - tank to pump

5. Fill the tank

3. Plumbing - pump to house

6. Recommendation

PRE-INSTALLATION

1. Choose a tankHow to estimate what size tank would be sufficient for Municipal Back Up:

Size of tank = litres p/day X total days back up requiredi.e. 4 x people (600L) X 3 days = 1800L

2. Tank placementShould be placed where municipal supply can be intercepted, before entering the house.

3. 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:

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

www.jojo.co.za

The float valve is set tothe level of municipal

water you want to keepin your tank at all times,

the rest is being filled up with rainwater.

Larger tank is required,due to a certain level

being constantly filledwith municipal water,

and the excess is rainwater

Ensure base issound, level,

smooth and widerthan diameter of

the tank.

Non return valves areinstalled to ensure no back

pressure to municipalsupply. For more detail refer
