2) Proper sizing of rainwater collection and storage systems is important. The amount of rainfall, roof size, and intended water uses must be calculated to ensure adequate supply.
3) Rainwater needs to be filtered before storage to remove debris. First-flush diverters and sediment filters

Rain water harvesting is an important way to conserve water resources for the future. As populations and water usage increase, groundwater levels are declining due to overuse. Rain water harvesting helps replenish groundwater by collecting rainwater and allowing it to percolate back into the water table. It has many benefits like increasing water availability, reducing soil erosion and flood risks. While all rainwater cannot be captured, understanding factors like catchment area, rainfall patterns, and runoff coefficients can help estimate the potential for rain water harvesting in a given location. Rain water harvesting is vital for ensuring adequate water resources for the future.
Rainwater harvesting has become a mainstream sustainable practice for commercial buildings. It offers opportunities to decrease water costs, ease stormwater management burdens, and demonstrate environmental stewardship. Well-designed systems integrate collection from roofs, storage in tanks, and distribution to uses like toilets and landscaping. While paybacks are typically 10-15 years, rainwater harvesting supports green building goals and can gain projects up to seven LEED points. The type of building and location must provide sufficient roof area and rainfall to justify the costs of a system. Regulations also require treated non-potable water be labeled as such. Case studies in the article illustrate real-world system designs and costs.
The document discusses the benefits of exercise for mental health. Regular physical activity can help reduce anxiety and depression and improve mood and cognitive functioning. Exercise causes chemical changes in the brain that may help protect against mental illness and improve symptoms.
Urbanization has significantly increased the amount of impervious surfaces like roads and buildings, altering the natural water cycle. Over 100 million acres in the US are now developed. This causes more stormwater runoff, carrying pollutants directly into waterways. Current stormwater infrastructure is inadequate, as it was designed only to convey runoff efficiently rather than treat pollution. As a result, stormwater is the top pollution source for over half of ocean shorelines and a third of estuaries. Combined sewer overflows also introduce untreated sewage during heavy rains. New approaches are needed to manage stormwater sustainably.
The document summarizes strategies for ensuring access to safe drinking water globally. It discusses four approaches: seeking new sources like desalination, saving and redistributing existing supplies by reducing leakage, reducing demand through more efficient agricultural and industrial practices, and recycling wastewater. Case studies from different countries demonstrate successful implementation of these strategies, in particular harvesting rainwater and adopting innovative irrigation techniques. An action plan is needed to share these solutions and empower local communities to address their water needs.
The document provides frequently asked questions about rainwater harvesting systems in San Francisco. It discusses permitting requirements, system design and sizing, installation, operation and maintenance, costs, and resources for further information. Rainwater harvesting is legal for non-potable uses like irrigation and toilet flushing. Permits are required for cisterns but rain barrels are still being regulated. Proper system maintenance is important, and costs can range from $15 for a rain barrel to $1 per gallon for cisterns, not including installation. The city previously offered subsidies for rainwater harvesting equipment.
States Take a Closer Look at Rainwater Harvesting - USAD6Z
1. Several states are regulating or considering regulating rainwater harvesting as water becomes more scarce and its collection grows in popularity.
2. Washington state law currently requires permits for rainwater collection but lacks clear guidelines around exemption thresholds.
3. The Department of Ecology plans to draft rules that would exempt small rainwater collection systems from permits while prioritizing permits for larger systems to encourage stormwater management.
This document provides an introduction to rainwater harvesting, including its benefits and growing global interest. It discusses key global demographic trends like population growth and rapid urbanization, especially in Asia, Africa, and Latin America. This is creating challenges for water supply. Rainwater harvesting is presented as a decentralized solution that can help address these challenges in a sustainable way by augmenting freshwater resources. The document outlines the objectives and components of UN-HABITAT's guide on rainwater harvesting and its water for cities programme.
This document is the second edition of the Virginia Rainwater Harvesting Manual compiled by the Cabell Brand Center. It provides a comprehensive guide to designing, installing, and maintaining rainwater harvesting systems. The manual covers topics such as types of rainwater harvesting systems for different uses, benefits of rainwater harvesting, design guidelines, and case studies of rainwater systems installed in Virginia. It aims to educate about rainwater harvesting and promote its use as a sustainable water source that can help address issues of water scarcity, water quality, and stormwater management.

3. Plumbing for rainwater tanks
A guide for rainwater tank suppliers and plumbers
1. Introduction
Rainwater tanks can make an important contribution towards reducing the demand for drinking
water. However, certain requirements are necessary to protect reticulated drinking water and
wastewater systems and to ensure public health is not compromised.
If the installation of a rainwater tank (regardless of size) involves work affecting the water supply
system, sewerage system, stormwater drainage system, or any part of Sydney Water’s systems, then
such work can only be undertaken with Sydney Water’s approval.
Sydney Water has developed the following guide on the technical and regulatory requirements for
plumbing from rainwater tanks. This is to ensure that the rainwater service cannot accidentally
backflow into the drinking water main or be cross-connected to the drinking water supply within the
property. Any cross connection would change the quality of the drinking water.
As part of our Operating Licence and Customer Contract, Sydney Water has a responsibility to ensure
that the quality of drinking water supplied to our customers is maintained. As the plumbing
regulator in our area of operations, Sydney Water also has responsibility to ensure that the drinking
water quality is maintained within the customer’s property.
In this guide, you will find detailed requirements that must be met when installing drinking water
top-up for rainwater tanks, technical drawings and fact sheets that your customers can obtain from
the Sydney Water website.
You can find out more about rainwater tanks from our website www.sydneywater.com.au or by
phoning our Plumbing Policy, Standards and Regulation group on 9952 0576.
Council Approval
The NSW government has amended the State Environmental Planning Policy (SEPP 4) so that
rainwater tanks with a capacity of 10,000 litres or less do not require local council approval provided
they meet the conditions outlined in SEPP 4. Details are provided in Appendix 2.
Installation of rainwater tanks with capacity above 10,000 litres still require local council approval.
Plumbing requirements Information for rainwater tank suppliers and plumbers APRIL 2003 1
4. 2. The guidelines
a) Application
These guidelines apply only to the plumbing for rainwater tanks that collect water from the roofs of
residential properties.
The guidelines do not apply to:
• Rainwater tanks that are not connected to the internal plumbing and do not have top-up from the
reticulated drinking water supply.
• Tanks that collect ground water runoff.
• Roof plumbing to the tank.
Rainwater tanks on commercial and industrial properties need to comply with Sydney Water’s Backflow
Prevention Policy and the New South Wales Code of Practice: Plumbing and Drainage.
b) Rainwater uses
Rainwater can provide an alternative source for the following:
• toilet flushing
• garden irrigation
• washing cars
• filling ornamental ponds
• washing machines
In line with NSW Health recommendations, Sydney Water does not recommend the use of rainwater tanks
for drinking purposes where a reticulated drinking water supply is available to the customer.
In this case NSW Health does not advise using rainwater for:
X drinking
X cooking or other kitchen purposes
X personal washing, such as baths, showers, hand basins and bidets.
2.1 Approval to install a rainwater tank
Under no circumstances is a rainwater tank permitted to be built over a Sydney Water maintenance
structure or within any Sydney Water easement, regardless of tank size.
Tanks not connected to the plumbing
Sydney Water’s approval to proceed is not needed unless the tank capacity is greater than 10,000 litres. If
the tank capacity is greater than 10,000 litres Sydney Water needs to assess whether the tank is situated a
sufficient distance from Sydney Water’s sewer. This is the same requirement as for any proposed building
application.
A plan illustrating the location and size of the proposed rainwater tank must be supplied. Sydney Water’s
standard building over sewer procedures will apply. If it is a sufficient distance from the sewer, then Sydney
Water or a QuickCheck agent can give approval.

5. 2.2 Sydney Water requirements
Below is a summary of Sydney Water’s main requirements regarding plumbing for rainwater tanks for
residential customers. Note: Words in italics are defined in Section 4.
a) Sydney Water needs to be informed of all proposed rainwater tank installations so that the meter
can be replaced with another containing a backflow prevention device.
b) There must be no direct connection between the rainwater tank and Sydney Water’s reticulated
drinking water supply.
c) An application must be made to Sydney Water if the property owner wants a top-up from Sydney
Water’s drinking water supply to the rainwater tank, as this is defined as an indirect connection.
d) Top-up will be limited to a trickle top up to ensure that the water pressure to other customers is not
compromised.
e) Top-up to the rainwater tank is not permitted from the reticulated recycled water supply.
f) In certain circumstances, Sydney Water can refuse to allow a connection from its system to the
rainwater tank.
g) Where a higher risk is assessed, Sydney Water may require the property owner to install a higher
hazard Backflow Prevention Device at the property owner’s cost.
h) The overflow from the tank should be directed to the stormwater system. It must not discharge to
Sydney Water’s sewerage system.
i) With all plumbing work, the plumber is required to make an application to Sydney Water at least two
working days before the commencement of work.
j) The plumber must arrange for the rainwater tank plumbing to be inspected by Sydney Water.
The plumber must also submit a Certificate of Compliance to Sydney Water and the customer at
the completion of the work.

6. 3. Connecting properties to rainwater
3.1 Administrative requirements
• The plumber is required to apply to Sydney Water for a permit to do the work as they would when
connecting any house service plumbing.
• Sydney Water’s plumbing inspector must be contacted when work is completed to carry out a final
inspection of the property before the Certificate of Compliance is submitted to Sydney Water and the
customer.
3.2 Rainwater tank plumbing regulatory requirements
• All plumbing work is to be done or supervised by a licensed plumber in compliance with these
guidelines and the NSW Code of Practice: Plumbing and Drainage
• Under no circumstances is there to be direct connection between the rainwater service and the
drinking water service.
Figure 1 provides a drawing of plumbing for above ground rainwater tanks with an indirect connection to
the drinking water supply.
a) Approved materials The full
Australian
Materials used in the rainwater tank plumbing must comply with AS/NZS 3500 Part 1 Standards
Mark
Water Supply Section 2 Materials and Products
Approved materials are those which have gone through the product approval process
Water
and have had a licence granted to mark the product accordingly. The certifying body Mark
provides the manufacturer with the following licensed marks to indicate that the
products comply with the relevant standard. To the right are the current three types of
“Marks” that indicate that the product has been certified. Type Tested
b) Pipes and labelling
Pipe materials to be used for rainwater need to be approved products and be clearly and permanently
identified ‘RAINWATER’ continuously along the length. This can be done for below ground pipes by using
identification tape (made in accordance with AS2648) or for above ground pipes by using adhesive pipe
markers (made in accordance with AS1345).
Identification tape marked ‘RAINWATER’ must be at least 75mm wide. The identification tape is to be
installed on top of the rainwater pipeline, running longitudinally, and fastened to the pipe at not more
than 3 metre intervals.
Every rainwater tank outlet must be labelled ‘RAINWATER’ on a permanent sign. An example is shown in
Figure 2. AS1319 provides direction as to appropriate layout, size and face materials for signs.
4 Plumbing requirements Information for rainwater tank suppliers and plumbers APRIL 2003
7. c) Proximity to other services
Rainwater pipes must be separated from any parallel drinking water service.
Above ground pipes
Any rainwater pipe installed above ground must be a minimum of 100mm away from any drinking
water pipe.
Below ground pipes
Any rainwater pipe installed below ground must be a minimum of 300mm away from any drinking
water pipe.
d) Backflow prevention
Check that all the following backflow protection is in place:
Above ground rainwater tanks
• Sydney Water has replaced the old meter with one containing an integral dual check valve for 20 -
25mm
meters.
• For meters 32mm or above, you need to install a dual check valve adjacent to the meter.
Below ground tanks
• A testable backflow prevention device must be installed at the meter. It should be noted that for below
ground tanks the cost of the device and its installation must be met by the customer.
• The device must be tested annually. The cost of this annual check is to be met by the customer.
Testable backflow prevention devices
These must be tested by a plumber accredited by Sydney Water. Accredited plumbers are listed on our
website at http://www.sydneywater.com.au/html/yourBusiness/backflow/bckflw_plumber_search.cfm
A completed Backflow Prevention Device - Inspection and Maintenance Report must be forwarded within 2
working days of test completion to:
Sydney Water Corporation
Backflow Prevention Group
Chatswood NSW 2067
For information on device testing requirements call 1800 680 636 or check out our website.
Plumbing requirements Information for rainwater tank suppliers and plumbers APRIL 2003 5
8. e) Water meters
Where a rainwater tank is installed a meter with an integral dual check valve will be provided for each
property with a current 20-25mm water meter. Property owners will be requested to advise Sydney Water
when a rain water tank is installed at their properties for an Integral dual check valve water meter to be
fitted free of charge.
20mm water meters with integral dual check valves
The dual check valves are built into the meters and will provide backflow protection to the drinking water
supply system. There are no changes needed to the drinking water service installation requirements as the
integral dual check valve meters are of the same length as existing meters.
Plumbers will be able to identify the new integral dual check valve meters by the longer “spud” at the end
connection of the meter. The check valves will also be visible from the end of the meter and plumbers
should ensure that they are not damaged during installation.
As Sydney Water will be providing 20mm drinking water meters with integral dual check valves plumbers
may now use approved ball valves at the meter location as accepted in the Australian Standard AS/NZS
3500, Part 1, Clause 5.4. Using ball valves at the meter will lower the amount of water pressure loss within
the drinking water service and minimise future maintenance.
Contact Sydney Water on 13 20 92 to arrange for a replacement meter with an integral dual check valve
f) Top-up service
The tank must meet Sydney Water’s storage tank requirements if top-up is required. The inlet drinking
water service must have a visible air gap between the reticulated supply and the tank external to the
rainwater tank.
The drinking water top-up service will only be permitted as a trickle top-up. This maintains the drinking
water pressure for internal purposes when the tank is filling. It also limits pressure fluctuations when flow
to the tank turns on/off.
Note: Top-up to the rainwater tank is not permitted from the reticulated recycled water supply.
Flow rate
For single residential properties, the flow rate of the trickle top-up into the tank from Sydney Water’s
reticulated supply must be restricted to a maximum of 2 litres/minute.
For townhouse or unit development, the flow rate of the trickle top-up into the tank from Sydney Water’s
reticulated supply must be restricted to a maximum of 2 litres/minute times the total number of
townhouses or units in the development.
Note: Sydney Water will generally allow an indirect connection between the tank and the reticulated
drinking water supply as long as the requirements outlined in 3a) to f) above are met. This is subject to the
disclaimer that, in accordance with the Customer Contract, Sydney Water is not responsible for any water
collected in a rainwater tank.
6 Plumbing requirements Information for rainwater tank suppliers and plumbers APRIL 2003
9. 4. Definitions
Above ground A tank collecting roofwater only which is either:
rainwater tank • fully above ground or
• at least half the tank is above ground and the view of and access to the inlet
pipe, air gap and overflow pipe are unobstructed.
Backflow A backflow prevention device is a device, to prevent the reverse flow of water
prevention from a potentially polluted source into the drinking water supply system. All
device backflow prevention devices need to comply with AS/NZS 2845.1
A tank collecting roof water only which is either:
Below ground
rainwater tank • fully or mostly underneath the ground
• where the view of and access to any one of the air gap, inlet pipe or
overflow pipe is obscured by the ground or something similar e.g. rockery or
garden bed.
There should be no possibility that surface run-off eg: on a sloping site will
drain to a rainwater tank.
Connection See direct connection or indirect connection.
Direct connection Direct connection occurs:
• where a pipe containing water from Sydney Water’s reticulated supply is
directly connected into a tank or pipe containing water from a rainwater
tank, or
• where the outlet of a pipe containing Sydney Water’s reticulated supply is
submerged beneath the surface of water from a rainwater tank.
Note: Direct connection is expressly prohibited in Sydney Water’s Customer
Contract (clause 8.4) because of the risk of backflow of tank water into the
reticulated supply.
Dual check valve (DCV) A device to prevent backflow caused by backpressure, which incorporates two
independently operating force loaded non-return valves.
Indirect connection Indirect connection occurs between a rainwater tank and the Sydney Water
supply where the outlet of a pipe containing drinking water from the Sydney
Water reticulated supply is separated from the water in the rainwater tank by a
visible air gap. This ensures that there is no possibility of the rainwater
backflowing into the Sydney Water supply.
Reduced pressure zone (RPZ) A backflow prevention device for high risk connections.
Standard connections Connections of 20 - 25mm pipes.
Testable double A device to prevent backflow caused by backpressure, which has two
check valve (TDCV)
independently operating force loaded non-return valves and incorporates
specific test points for in-service testing.
Trickle top-up Trickle top-up is the slow filling of the tank from the drinking water supply. It is
designed to minimise effects on the reticulated system and allow for a
reasonable re-supply into the tank over a period of several hours.
Visible air gap The unobstructed vertical distance through the free atmosphere between the
lowest opening of a water service pipe or fixed outlet supplying water to a
fixture or receptacle and the highest possible water level of such fixture or
receptacle.
