Water and Sanitary Services Assessment Summary
Introduction
We have a statutory responsibility to carry out Water and
Sanitary Assessments under Sections 124-129 of the Local
Government Act [2002]. The first assessments were completed
in November 2004. This set of Assessments updates the 5
year period from December 2004 – May 2010. Some original
Council managed water and wastewater networks assessments
remain current in that no changes of material significance have
occurred.
Scope of the Assessment
Given our resources available, updated assessments have only
been prepared for water supply networks that fit in with the
following criteria. Networks are then grouped into three
categories, with regard to how they are affected by the criteria.
All wastewater network assessments have been completed. The
criteria includes water supply networks that have:
• Undergone considerable growth or change of use
• Incorporated upgrades to supply, treatment disposal or
have new works
• Recently been topical in the public arena or are
politically sensitive
• Transgressed significantly in public health or
environmental impact
• New and not covered by the original assessment
• Become subject to new legislation or notably different
consent conditions
Group 1
Water networks having significant capital work/alteration
completed or pending that markedly improve network
capacity, performance, service levels or resource consent
compliance and are shown as full updates.
Presented as full updates covering all matters not detailed
in the original assessments
1. Ashley Main Intake
• new intake bores, relocation of treatment
2. Ashley North Area

3. Amberley Urban Water

4. Hanmer Springs Water
• new water treatment & reservoirs
5. Cheviot Main Intake

6. Cheviot Urban Area

7. Culverden Water

Group 2
Water networks affected by current/anticipated
issues or may warrant some improvement/require
works and are shown as brief summaries.
1. Leithfield Beach Water
• bore corrosion and water quality deterioration
2. Waiau Urban Water
• treatment deficiencies & asbestos reservoir roof
3. Upper Waitohi Water
• supply reliability and consumer expectations
Group 3
Water networks that have experienced nil or little change
in demand or operational aspects over the past 5 years or
where consumers are not demanding treatment/disposal
or water source improvements, so are therefore not
included in the June 2010 assessment update.
Water:
1. Hurunui Main (Hurunui)
2. Lower Waitohi (Hurunui)
3. Peaks (Hurunui)
4. Kaiwara (Cheviot)
5. Parnassus (Cheviot)
6. Blythe (Cheviot)
7. Balmoral (treated with chlorine)
8. Amuri Plains (treated with uV)
9. Waiau Rural
10. Hawarden-Waikari (treated with uV chlorine back-up)
This approach is considered appropriate with how the LG Act
[2002] is interpreted. It is also considered that the required
Public Health Risk Management Plans [PHRMP] being very
similar in purpose and content, would be better integrated
with future assessments to minimize duplication of effort and
reporting.
As the Assessments and PHRMP documents are key reports on
activities, they sit well with our obligations to maintain Activity
