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
10
Waste Water - Sewerage
Connect to public supply Only foul waste not surface water
Gravity or rising main Drawings – Longitudinal sections etc
Pump Station New standard specification – KCC website
- access, overflows, flow recorder, standby generator, dosing - septicity etc Pre Planning meeting advised

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

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

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
