Integrated Rainwater Harvesting Systems

Often the simplest of methods can be the most effective…

Harvesting rainwater is one of the oldest and most elemental of ways in which we can live sustainably with nature. Only now is the value of water being recognised as it becomes an increasingly precious resource.

Here at Kingspan Environmental, we have been designing and installing rainwater harvesting systems for over a decade. While we continue to follow the principles of rainwater harvesting, our systems have evolved through our knowledge, experience and the latest technology.

The result?

An advanced range of systems, bringing intelligent sustainability to all modern buildings.

Rainwater Harvesting is not a new concept. Since earliest times, mankind has captured rain in order to provide a simple and accessible supply of fresh water.

With the introduction of mains water supply, harvestingmethods in the developed world have been largelyreduced to the use of garden waterbutts. In most buildings naturally clean rainwater is left to wash away while expensive purified water is used for all applications with only a fraction being used for potable-use. In recent years it has become harder to ignore this illogical way of using our natural resources.

Water has become a valuable commodity. Increased awareness of the environmental issues surrounding water reserves, drainage and a cultural shift towards sustainability have also meant that Rainwater Harvesting is more effective and significant than ever before.

What is Rainwater Harvesting?

The Basic PrinciplesThe principles behind Rainwater Harvesting are simple.

Any system has a method of collection (e,g a roof), a storage vessel (tank) and a delivery facility (be it a simple on/off tap or pipework system).

Integrated rainwater systems still adhere to these elementary steps, but use modern technology to refine the process with automation and filtration.

Integrated Rainwater Harvesting SystemsThe rainwater that falls onto a building’s roof is channelled through standard guttering and pipework. Rather than going into the drain, the water passes through a mesh filter (to remove leaves or debris) before entering a storage tank.

When needed, this water is then automatically pumped back into the building and, (after further filtration), is put to use in non-potable applications, such as toilet flushing, laundry or commercial washdown areas.

Float level switches within the tank alert an electroniccontrol device to divert to mains supply should the storage tank run empty. The system will always draw on harvested water first.

System variations include the use of a header tank and booster sets, but in essence any integrated Rainwater Harvesting system follows the same process in its operation.

RE-USE

Whether it falls from the sky or comes out of a tap, our relationship with water has fundamentally changed. There is more pressure than ever before to ensure that every drop of water is accounted for and controlled.

On one hand, water has become a valuable commodity. On the other, climate change has altered the pattern of rainfall – leading to shorter heavier bursts of rain that pose major risks to the current drainage infrastructure.

Environmental issues are becoming increasingly important and there is a growing public awareness of the contribution that good building design can make to reducing pollution and improving the environment.

Water Stress AreasAs this map shows, the South of the country is susceptible to falling to near critical levels of water shortage in relation to population. As these areas become even more densely populated, the demands on the existing water supply infrastructure continues to increase at a rate that is clearly unsustainable.

Reservoir storage is finite regardless of rainfall, thus the most effective solution to this imminent water supply crisis is widespread use of Rainwater Harvesting.

Legislation, Initiatives and the Future

The Code for Sustainable HomesDefinition: Government owned environmental assessment method for certifying and rating new homes in England. It was launched in December 2006.The CSH measures the sustainability of a new home against categories of sustainable design, rating the ‘whole home’ as a complete package rather than on a single characteristic.

The CSH uses a one to six star rating system to communicate the overall sustainability performance of a new home. The CSH sets minimum standards for energy and water use, set at incremental levels.

Implications – the countdown to 2016The Government has detailed a timeline for the adoption of the CSH which concludes with net-zero carbon Level 6 homes by 2016.

Currently the average water use is 150 litres per person per day. To achieve ratings at the higher end of the Code the developer will have to install more water-friendly fittings and appliances to dramatically reduce this water consumption figure.

To reach Code Level 6 (80 litres per day) a form of rainwater harvesting will have to be adopted.

SUDSAs more river valleys become developed with hard surfaces (paths, roads and roofed areas) the volume of rainwater that runs off the land increases.

This can have a severe effect in a watercourse where flash floods can occur downstream where the volume of water entering the system can be extremely high due to a cumulative effect of development upstream.

To address this problem, the drainage systems of towns, cities and developments have been surveyed and a policy of Sustainable Drainage Systems (SUDS) has been developed to counteract the problems being encountered.

• SUDS addresses issues of the quantity and quality of the water run-off from sites.

Attenuation systems (tanks and rainwater harvesting systems) and separators (to remove oil contaminants from discharges) are required.

The UK Government has stated its commitment to tackling both the causes and consequences of climate change. To this end it has started to introduce a clear, credible, long-term framework for the UK to achieve its goals of reducing carbon dioxide emissions and ensure steps are taken towards adapting to the impacts of climate change.

Surface Water Runoff (SUR1) DocumentThere is a mandatory requirement, under certain conditions, that rainwater harvesting must be implemented on site to greatly reduce the quantity of surface water runoff from the development.Infiltration on site is the preferred option but many sites will be unable to provide full infiltration due to ground conditions and /or space constraints.

Rainwater harvesting will provide a cost effective method of surface water runoff reduction by allowing the collected water to be used within the properties being developed.

Building Regulations Part H

BREEAMBREEAMDefinition: Building Research Establishment Environmental Assessment Method. A suite of environmental assessment rating tools designed, operated and owned by BRE, first launched in 1990.BREEAM is the world’s longest established and most widely used environmental assessment method for buildings. It sets the standards for best practice in sustainable development and demonstrates a level of achievement.

Predominantly a design-stage assessment, BREEAM assesses buildings against a set criteria and provides an overall score which will fall within a band providing either a; PASS, GOOD, VERY GOOD, EXCELLENT or OUTSTANDING rating.

BREEAM is applied across the building spectrum through various packaged forms, created to suit individual types of building – for example common types of buildings can be measured under packages including BREEAM Education, BREEAM Prisons, BREEAM Offices, BREEAM Multi-residential and others.

The original BREEAM Eco-homes was created to tackle domestic homes. In April 2007 the Code for Sustainable Homes replaced Ecohomes for the assessment of new housing in England. EcoHomes 2006 will continue to be used for refurbished housing in England and for all housing in Scotland and Wales.

COMMEnTRainwaterHarvesting is recognisedacross thevariousBREEAMbuildingpackagesandscoreshigh-creditation under the Water Efficiency sector.

Definition: Within the Building Regulations 2002, part H3 sets out guidance and requirements for rainwater drainage. Building regulations are specific to particular building procedures and components. Part H3 has increased the responsibility of developers and contractors to ensure that buildings are designed with demonstrable methods of sustainable drainage.

Rainwater carried from the roof of the building has to be managed while paved areas around the building should be constructed so that they are suitably drained. Piping the flow into the mains is no longer the immediate solution.

Provision for managed disposal follows a hierarchy of discharge options:

An adequate soak-away or some other adequate infiltration system (e.g swales, filter drains, infiltration basins etc). Not always a practicable option, requiring a designated and secure land area.

A watercourse - This is dependent on consent granted, e.g the Environment Agency or applicable authority.

A sewer - Consent is only given if capacity is deemed available. If there is not enough capacity a separate system should be put in place - an often prohibitive cost.

COMMEnTThe building Regulations place firm emphasis on the requirements of the developer/contractor to deal with the rainwater drainage on site.

A Rainwater Harvesting system provides developers & contractors with an effective infiltration system as a means of reducing the impact of the rainwater discharge on site. In so doing, many of the site drainage requirements of building regulations can be satisfied, and thus ease theprocess of gaining planning permission.

It is also apparent that such frameworks are top of the agenda for the Government in Ireland.

Building sustainable homes requires all sorts of environmental impacts to be minimised in addition to carbon dioxide emissions, such as water use, waste generated, and materials for building.

Water-use ApplicationHarvested rainwater can be used to replace mains water in nearly all non-potable applications.

The most popular role for rainwater is to serve a building’s facilities such as toilet flushing, washing, or garden irrigation – each requiring a continual and sizeable consumption of water.

Commercial applications also include these uses, but can be more varied. Past installations have seen rainwater put to use in a diverse range of functions including vehicle washdown, heating and cooling applications, materials manufacturing, farming and livestock and scientific applications.

Understanding your system - factors to considerWhatever the design of covered structure or building, a Rainwater Harvesting system can be designed and installed to capture the rain that falls upon it.

As a starting point, it is worth considering the fundamentals that govern the design and thinking behind each individual installation.

There are Five basic factors to consider:

new Build or Retrofit?Putting the rainwater storage tank into the ground is the biggest task on any harvesting system’s installation agenda. Logically, the prime time to install the tank is at the ground-working stage of the project’s construction schedule.

This poses little problem for new-builds as the foundations and drainage will need to be dug and excavation plant will be on site. However, for retrofit installations, careful thought should be paid to both physical restrictions (e.g access to proposed tank location), plus any preparation work that may be required after the install.

See page 15 for more details of tank location options.

2FACTOR

Roofing Area and DrainageA building’s roof area is its rainwater catch net. The larger the roof, the larger the volume of water that can be collected.

It is very much down to the application that decides just how much rain (and thus diverted roof area) may be required, but there are also many other advantages in using the system as an intrinsic part of the building’s overall sustainable drainage (SUDS) scheme.

3FACTOR

Scale of UseOn larger building schemes it may be more practical to adopt a multiple-tank layout to cater for the expanse of roof space. This places localised reserves of water exactlywhere needed, rather than one large tank requiring a number of lengthy supply pipes.

Alternatively, a single tank can feed many outlets – an arrangement common to domestic house developments where each dwelling draws off one collective tank.

Available Internal Tank SpaceMost rainwater systems supply water direct from the underground rainwater tank, but it may be desirable to have an elevated header tank (usually located in a loft area or roof cavity) to store filtered water after the main tank.

This has an advantage that in the event of a power cut or if electricity is being rationalised, the building continues to receive a supply of harvested water.

Introducing the Envireau range of integrated harvesting systems

Multiple Housing Sites & Single HousesHousing developments, barn conversions, housing associations, Self-build and existing housing.

Uses: Toilet flushing, hot water, washing machines, garden irrigation and car washing.

Kingspan have been designing and manufacturing integrated rainwater systems for over a decade. Within that time we have recognised the need to retain a bespoke approach to addressing a building’s needs, but also the advantages that packaging the systems can offer the consumer in terms of ease, reliability and refinement.

What we have developed is the Envireau system. Easy to install, simple to maintain, automatic in operation; Envireau delivers a dependable supply of harvested rainwater.

Commercial / Industrial & Agricultural

Offices, schools, industrial estates, distribution centres, farms, farm shops and holiday accommodation.

Uses: Toilet flushing, washdown, vehicle washing,irrigation and process.

Gravity and Direct Systems

The Envireau system has two primary options; the Gravity System uses an elevated header tank to store filtered water after the main tank. The Direct System pumps water from the main storage tank and is used where a header tank is impractical (Both systems are explained in more detail on the next page).

Precise Component SelectionBoth the Gravity and Direct systems permit totally flexible scope for component selection in order for Envireau to be tailored to each building and water application.

Tanks are carefully sized and selected to take into consideration factors such as roof water yield, projected water consumption and ground work criteria such as prevailing water table, soil conditions and requirements for trafficked access.

Filters and Pumps are likewise selected to match the system specifications and performance criteria, to minimise maintenance and to ensure the water is kept at an optimum level of clarity and supply pressure.

12

System Options

The Direct System is suitable for domestic and commercial applications. This system is used where it is impractical to have a header tank – for example, in homes that have converted attic spaces and simply no available space.

The system pumps filtered rainwater direct from the holding tank to the various appliances.

When the holding tank is running dry there is a small automatic charge of mains water into the underground storage tank to ensure the system never runs dry. The main advantage of this system is that rainwater is delivered to the appliances at mains pressure.

Envireau Direct System

Domestic & Commercial uses

• WC and urinal flushing• Irrigation and landscape watering• Garden watering

Direct System Components

• Tank manufactured from Polyethylene or GRP, capacity from 1,800 litres up to 80,000 litres in a single tank. Larger units available on request.

• Primary leaf filter, internal tank filter and in-line fine particle filter

• Submersible pump (below water level in tank, pumps water to control panel)

• Depth sensor

• Envireau panel (controls pump)

• Solenoid valve (regulates the supply of mains water)

13The Gravity System has a major advantage in that in the event of a power failure on site (or the rain stocks running dry) the system will automatically switch to mains water supply to ensure a continuity of service.

The header tank contains two independent valves operating both the mains and rainwater supply. The system will always draw on rainwater first and pump to the required applications.

System Options

Building designs may require water to be pumped over considerable distance (e.g, an airport terminal) or height (a multi-storey office or apartment building). In such instances the use of a booster system is required.

A booster set comprises of a single or a series of pumps and often an accompanying holding tank. Operating automatically, the booster is designed to ensure a balanced supply of main-water throughout the building.

The Envireau system is entirely compatible with booster sets and the plumbing infrastructure of large scale building designs.

Booster System

Modern buildings are increasingly designed to take advantage of the benefits delivered bysyphonic roof drainage.

As the name suggests, rainwater is syphoned (or sucked) down off the roof, rather than relying on just gravity flow, as per traditional gutter pipes.

Syphonic systems require considerably fewer downpipes and without the reliance on gravity, piping options are far more flexible, making it far easier to route rainwater to a specific collection point for harvesting.

Rainwater from any number of outlets can be linked to a predetermined discharge point, allowing even the biggest of roofs to be fully maximised in rainfall capture.

Tank Location Options

Above Ground Tanks provide the quickest and simplest facility for storing harvested rainwater. The free-standing tanks require no specialist installation and are manufactured from tough rotomoulded plastic. For larger capacities of water, multiple tanks may be connected together to meet storage requirements.

Above Ground Tanks

Features and Benefits• Capacities from 1,300 to 10,000 litres• GRP storage tanks available up to 200,000 litres• Immediate connection on site• Portable and re-useable• Facility to link additional tanks as required• Tough and durable rotomoulded construction• UV protected

TankLocationOptions

Sectional Tanks are constructed from modularpanels that are bolted together on site. They areparticularly useful as they enable confined spaces (such as a basement area or void) to be utilised for rainwater storage. The tank panels can be easily handled and are easy to erect. By adding more panels, sectional tanks deliver an infinite range of sizes and capacities.

Sectional Tanks

Features and Benefits• Infinite range of sizes and configurations • Can be adapted as storage requirements change • Ability to be installed in areas with restricted access • Quick and easy assembly• Highly economical transportation • Available in GRP or galvanised steel

The most common water storage option is to locate the harvested rain below ground. Kingspan’scomprehensive range of Polyethylene or GRP, storage tanks provide an unobtrusive and secure solution for any size of building project from 1,800 litres up to 80,000 litres in a single tank.

Below Ground Tanks

Features and Benefits• Capacities from 1,800 to 80,000 litres within a single tank• Multiple tanks can be joined to cater for larger volumes• Can be installed under trafficked areas (with concrete support)• Complete packaged units delivered directly to site• Economical volume storage

Information requiredOur technical team can study your building plans and present a ‘best-fit’ system designed to maximise theeffectiveness of a rainwater system and makes best use of the available tank installation area.

Alternatively, it may be more desirable to tailor Envireau to particular client criteria - for instance to supply a specific water application, interface with existing electrical/plumbing systems or a non-standard tank installation (e.g below a car-park or similar).

A more tailored request (such as the latter) will need some preliminary decisions to be made to enable a system to be created, but we offer full supporting advice and guidance at concept stage.

Further Advice

A KingspanWater Envireau system is not complicated technology. Likewise, our professional team aim to make the specification, purchasing and installation process equally as simple.

Although many buildings share similar characteristics, we treat each inquiry as a bespoke design. This takes into account a variety of factors including water catchment yield (roof area), storage tank facilities, the overall building envelope and of course the water application – be it for toilet flushing, washdown or other requirement.

We also consider future changes in our design, such as building / user expansion or change of use.

There are Five basic steps to consider:
