An Ghearmáin• Bailítear Cáin Bháistí ón méid uisce a ritheann chun srutha isteach sa

séarach stoirme áitiúil ó bhrat dromchla neamh-thréscaoilteach an tí. • Rain taxes collected for the amount of run off into the local storm sewer that is generated from the impervious surface cover of the property.

An Fhrainc• Tá lacáiste cánach de 40% suas go dtí €5,000 curtha ar fáil do Chóráis

Bailithe Báistí • A tax rebate of 40 % up to a maximum of € 5000 is be provided to all

RWH systems. An Bheilg

• Reachtaíocht Náisiúnta – Caithfidh Córais Bailithe Báistí a bheith suiteáilte i bhfoirgnimh nua go léir do leithris agus d’úsáid uisce

lasmuigh. • National Legislation - all new constructions need to have RWH systems installed for the purpose of flushing toilets and external water uses.

“A Zero Waste Approach to Water ”

To develop an integrated water strategy for Ireland we need:• Innovative thinking • Sustainable and resilient technologies• Education curricula reform • Co-ordinated Government and

Community Action • Appreciation of rainwater and

wastewater as a valuable resource• Design Water In rather than Water Out

22

• Best International Practice • Innovations in Rainwater

Harvesting• New build versus retrofit• Water Quality and Quantity• Evaluate Cost Benefits to the

Consumer and Producer• Barriers and Incentives• Vocational Training• Guidelines & Technical

Standards• Monitoring and Evaluation

Reduce, Reuse and Recycle Pilot StudiesFuture Design - Water In rather than Water

Out

Water / Wastewater in Gaeltacht Regions

• Appropriate Resilient Technologies for– Water / Wastewater Treatment, Conservation

and Reuse• Meeting peak demands from tourism

• Island supply • Vocational training

• Job creation • Monitoring and Evaluation
