FUNDING THE SERVICE

Page 8: Water Conservation Awareness - Green Business

WHERE IS THE FUNDING GAP?

The Three Card Trick:

How can the Water Service

Authority deliver a service when

the money is filtered through

Central Government?

To whom does the Customer

complain if the service is poor, if

the responsibility is split?

Shared responsibility is no

responsibility.

The service provider must

have control of the revenue.

DOMESTIC WATER CHARGES

Water Charges without meters first?

Why not?

OFWAT => Only 10% difference in consumption.

1.2 million properties (public water)

€500 standard charge; €300 for low occupancy.

Allow 10% for Administration;

Allow 10% for Social Welfare Assistance.

=> Annual Revenue of €384m per annum

(Displacement of Exchequer Funding; But Direct.)

Page 11: Water Conservation Awareness - Green Business

DOMESTIC WATER METERS

Procurement & Installation Cost = €0.5bn to €0.6bn

Change in Customer Behaviour (10%)

Saving of €15m per annum of water production costs.

Based on 70:30 Fixed:Variable cost split.

Capture of Customer-side Leakage (50%)

Saving of €75m per annum of water production costs.

Based on 70:30 Fixed:Variable cost split.

Six (6) years to recover the costs of metering.

Excludes value of deferred capital investment.

Page 12: Water Conservation Awareness - Green Business

UNIVERSAL WATER CHARGES

FULL COST RECOVERY

Water charges in Ireland are relatively low.

Germany = €5.50 /m3; Ireland = €2.30 /m3

This is not because we have magically become

more efficient than the Germans!

Germany seeks full cost recovery; Ireland does not.

Historic Mains Rehabilitation;

Abstraction Charges;

Stormwater Charges.

Page 14: Water Conservation Awareness - Green Business

THE INSURANCE PURSE

Who Benefits from Water Meters?

Claims – Subsidence & Property Damage

Due to water loss from leaking pipes.

Solution – Water Meters & Leak Alerts

Catch & Fix the leaks quickly.

Insurance Levy to help pay for water

meter installation?

Policy discounts for customers with

meters with leak alert facility?

Page 15: Water Conservation Awareness - Green Business

YOUR FUNDING GAP

The Home Owner also has a funding gap.

Needs financial help to make the home more water

efficient; and benefit from cheaper bills.

Water efficiency is a proxy for Energy efficiency

Extend the Home Energy Efficiency grants to include

water efficient fittings.

Water Conservation Schemes

Find a way of including the service pipe to the first tap.

The Toilet Scrappage Scheme 2011

Page 16: Water Conservation Awareness - Green Business

PRIVATE INVESTMENT

PPP Schemes for Treatment Plants

Typically DBO, without the private finance.

Performance assured; but so is the fee.

Is there scope for further private investment?

DBFO might be considered; but the larger schemes

have been completed;

Sell public water and waste water treatment assets to

the private sector and purchase the service;

The value of the Customer Database

Page 17: Water Conservation Awareness - Green Business

WATER SERVICE INVESTMENT PROGRAMME

The Construction Sector has suffered from the

funding gap more than any other part of society.

The continued contraction of the construction sector

demonstrates that the funding gap remains.

WSIP promises €3.8bn of contracts to start by

2012; but progress has been very slow.

The co-funding issues between Central

Government and Local Government must be

resolved quickly.

NEW STRUCTURES

Page 19: Water Conservation Awareness - Green Business

WATER SERVICES STRUCTURES

No lack of ideas for new structures

Some are ideologically motivated;

National Water Authority?

National Water Company?

National Roads & Water Authority? (NRA+)

Commission for Utility Regulation? (CER+)

Regionalised Water Service Authorities?

Shared Service Centres?

National Billing Agency?

Regional Water Management Units?

Page 20: Water Conservation Awareness - Green Business

ABSENT FRIENDS

Economic Regulator

Who audits the price of water?

Customer Representative

Who speaks on behalf of the Customer?

Customer Care Centre

Where does the customer go for information?

Custodian of the Source Water

Who is the custodian of the source water?

Page 21: Water Conservation Awareness - Green Business

ISSUES TO CONSIDER

If it ain’t broke (too badly) don’t fix it (worse).

Don’t bring water services into an existing organisation

as a solution to problems elsewhere.

Scale

If a local authority is too small to dedicate staff to

network management, then a larger scale is required.

Should billing be managed nationally;

and customer queries handled locally?

Separation of Powers

Who is the Regulator? [Price & Quality]

Who is the Service Provider?

Page 22: Water Conservation Awareness - Green Business

THE FUTURE OF WATER

To provide a professional and sustainable national

drinking water service with outstanding customer

service and well-managed infrastructure.

THE WATER BILL - POLICY

In accordance with the Governments Water Pricing Policy, all “non domestic” supplies are to be charged on a metered basis to recover operational costs of water provided and to achieve metering of all non-domestic customers. This is in accordance with the “polluter pays” principle and the requirements of Article 9 of the EU Water Framework Directive.

Water invoices are calculated by means of a metered charge based on the volume of water used.The charge for customers who have a water and sewage connection is based on the basis of the “water in/water out” principle.

Page 29: Water Conservation Awareness - Green Business

LIMERICK COUNTY COUNCIL (2011)

In respect of connections to the Council Water Network and Sewerage System:- €200 per annum meter charge plus €2.60 per cubic meter of water supplied.

In respect of connections to the Council Water Network only:- €200 per annum meter charge plus €1.15 per cubic meter of water supplied.

In respect of connections to the Council Sewerage Network only:-

€200 per annum meter charge plus €1.45 per cubic meter of water supplied to or used on the premises

Page 30: Water Conservation Awareness - Green Business

READ THE METER

An average water meter will look like the picture to the left.On top, you will see the serial number, 07M244508.

There will be 5 digits in black on a white background, and 2 (or 3) in white on red background. The black digits are cubic meters (m³). You are charged based on reading of these 5 digits.

In the middle is one red dial, which will rotate if water is running through the meter. The faster this spins, the more water is being used.

Page 31: Water Conservation Awareness - Green Business

DO YOU KNOW WHAT YOU SHOULD BE PAYING?

Typical Business uses 50 litres of water per

employee per day

If you have 10 employees, and you are on both

public water mains and sewers, then you would be

using:

50 x 10 = 500 litres/day = 0.5 m3/day

If you work a 5-day week, then the quarterly bill

should be:

0.5 m3 x 13 x 5 x €2.60 = €84.50 (by volume)

plus €50.00 (standing)

Total = €134.50 (/Qtr)

Page 32: Water Conservation Awareness - Green Business

SIMPLE WATER AUDIT

What if the bill is (a lot) higher than you expect?

Turn off all the taps

(early in the morning or late at night)

Check the Meter

If the “spinner” is spinning, then water is going through

the meter, i.e. probably a leak;

If it is not a leak?

You may be donating water to a neighbour!

Page 33: Water Conservation Awareness - Green Business

DIG A LITTLE DEEPER …..

Check for dripping taps

A dripping tap can lose almost as much water as one

employee;

Check for faulty fittings

Overflow and pressure-release valves;

Sometimes they empty directly to the drains;

Call a plumber

Call specialist leak detection firms, e.g. LowFlo

HOW TO TURN €20,000 INTO €4,000?

Page 36: Water Conservation Awareness - Green Business

WATER “IN” MAY NOT BE WATER “OUT”

The volume of Water coming in ……..

…….. equals the volume of water going out.

Not necessarily so.

And then there may be a Domestic Allowance?

Could be worth €500-€600 of discounts each year.

ANECDOTE:

A small UK local authority had requested a proposalfor a water conservation project to cover all theirbuildings, schools, offices sports centres etc.

While they were impressed by the environmentaland cost benefits they were concerned about theestimated capex charge - £35,000 to cover AMRand the installation of water saving devices.

On the morning of the meeting to discuss nextsteps the Authority received a water bill for £32,000for one school where a leak had gone undetectedfor 5 months.

The order was placed immediately.

RAINWATER HARVESTING (RAIN CATCHERS)

Page 43: Water Conservation Awareness - Green Business

RAINWATER HARVESTING PILOT PROJECT 20071. Rainwater harvesting is a sustainable water conservation measure.

2. Harvested rainwater is an underused source of raw water and its use has the potential to contribute to the sustainability of raw water sources of supply and to the long term viability of water treatment plants.

3. Harvested rainwater has the potential to supplement sources of water supply for non-potable uses.

4. The design and installation of a rainwater harvesting system should be undertaken by competent/specialist trained personnel.

5. Ongoing maintenance of a rainwater harvesting system is required to ensure optimum performance.

6. Current water charging policies act as a disincentive to the installation of rainwater harvesting systems.

7. The introduction of a significant level of grant aid would, therefore, be required in order to have rainwater harvesting considered a financially viable option.

8. The provision and siting of storage for harvested rainwater will depend on site restrictions and capacity needs.

9. The utilisation of harvested rainwater for domestic hot water use could, under appropriate conditions, be considered as a safe and sustainable alternative supply to mains water, with a possible reduction in demand of up to 80%.

10. The potential benefits of rainwater harvesting are not widely appreciated by the public at large or by those involved in building design and construction.

FROST PROTECTION

Business Disruption; Water Damage; Leak repair

Cost of water possibly less important;

Unless the leak is not detected.

Check that exposed pipes are lagged in cold

spaces;

Check that the boundary box is insulated;

Check that pipes are buried 750mm (30”);

Turn water off and drain system if closed for

holidays!

Page 46: Water Conservation Awareness - Green Business

LEAD PIPE REPLACEMENT

Many older properties still have old

lead piping between the boundary

and the building;

High risk of leakage (ongoing);

Apart from plumbosolvency health

risk;

Customer-side leakage is known to

be at least half of the overall leakage

in the system.

Page 47: Water Conservation Awareness - Green Business

BEHAVIOUR

Ofwat (UK):

Water metering reduces consumption by 10% in the

medium term;

People do not recognise water as expensive;

Education is very important:

Schools (Green Flag Initiatives)

Tap Tips

Dublin Local Authorities;

Page 48: Water Conservation Awareness - Green Business

WASTE WATER

Page 49: Water Conservation Awareness - Green Business

WASTE WATER

Fats, Oils & Greases (FOG)

Macerators

Stormwater Separation & Infiltration

Page 50: Water Conservation Awareness - Green Business

FATS, OILS & GREASES (FOGS)

FOGs are a menace for sewer

maintenance

Very costly & disruptive

Licensing & Inspection regime

Being rolled out nationally

Started in Dublin City Council

Grease Trap

Check that it is being used;

Check that it is maintained;

Check that it is suitable.

Page 51: Water Conservation Awareness - Green Business

MACERATORS

Installed under the sink to “chop up” food waste for

disposal to the drains;

A way of avoiding waste charges.

But:

They increase the organic loading at wastewater

treatment plants;

This is reducing the effective capacity of the treatment

plants;

The DEHLG and local authorities would like to see them

banned from sale;

The Food Waste Regulations (2009) indirectly curtail the

use of in-sink macerators.
