Pre-Planning Protocol - Connections

KCC & IW - jointly manage statutory consultations KCC to advise IW where significant impact – attend

– Advise applicant of any issues – subject to confirmation– Meeting between applicant and IW without Planning Dept present is

Completed application forms from developer– Should be returned to KCC - sent on to IW ( inc OS Maps )

IW will send out quotation & connection offer to customer– Connection fees, Payment method, Validity duration– Conditions, Direction to specifications, Instructions for works

Water and Wastewater Development Charges– KCC will no longer levy such charges– will be part of connection charge if applicable

KCC will process Road opening licence separately7

Submission – Pre planning

Pre Planning meeting - Site location map Scale of development Availability of services Proposed flows / demand Need for Flood Risk Assessment – submit if required

Application to include Design calculations Pipe sizes, Pump stations etc Drawings – services - on site & connection to outfall Capacity of existing network – constraints Longitudinal section – sewers SW pipes Wayleave agreements as necessary

9

Water Supply

Public supply– Metered – main & service– Min 24 hour storage - on site– Housing Estate min 100mm - looped

Private supply – Water quality tests - HSE – KCC ground water Source Protection Policy

Water Conservation– Dual flush systems, - Rainwater Harvesting– Water audit & leakage survey– Taps with water conservation mechanisms

Storm Water Management Policy - GDSDS– Design & construct & maintain– Sustainable Urban Drainage Systems – SUDS– Attenuation – On site storage systems – 1 :100 year storm event – Post development flows not to exceed green field runoff

Design– Min pipe size 225 mm– Return Period 1 – 5 yr - Surcharge analysis

Discharge – Public system – existing capacity - outfall – Arterial Drainage Act 1945 ( S. 50 ) – culvert sizes– On site - BRE Digest 365 - soakpits

Sustainable Drainage Systems

SuDS – “train” ( www.irishsuds.com )

FLOODING

Assessment of Application OPW website : floodmaps.ie Local Knowledge Flood maps – Local Area Plan / Dev Plan

OPW Guidelines to Local Authorities “ Planning System and Flood Management Guidelines” Flood Risk Assessment

High : only in exceptional circumstances Moderate : vulnerable developments - inappropriate Low : yes - engineering / planning criteria

14

General Policy

Development Plan – Strategic Flood Risk Assessment– One main municipal Sewerage plant – settlement – Promotion of water conservation

Constraints - Sewer Capacity– Case by Case basis– Large Development - may be premature– Smaller Developments - conditions re phasing – Priority to Developments

(a) Employment (b) Significant Community gain

Irish Water - 2 standard conditions – Connection agreement before any development commences– Public Health & Environmental sustainability - Capital Investment Programme
