context_page_description: Raglan is a small beachside town located 48 km west of Hamilton, New Zealand on State Highway 23. It is known for its surfing, and volcanic black sand beaches.
context_section_description: Raglan's water supply comes from a well and the nearby Waipatukahu (or Riki) Spring between Te Hutewai Rd and Omahina Creek, about 3 km (1.9 mi) south of Raglan, where water which has sunk into the volcanic rocks, seeps along the contact with the Tertiary beds.
  Water is chlorinated, pumped to a 1,335 m³ (294,000 imp gal) tank and distributed through about 42 km (26 mi) of pipes. Tanks at Bow St (1,000 m³ (220,000 imp gal)) and Cornwall Rd, (1,250 m³ (270,000 imp gal)) maintain pressure. Demand has been forecast at 3,606 m³ (793,000 imp gal) per day by 2034, based on a Waikato University population prediction assuming consumption of 260 l (57 imp gal)/person/day. However, in December 2015 use was averaging 1,510 m³ (330,000 imp gal) a day. The capacity of the spring is 4,800 m³ (1,100,000 imp gal) per day. Consent allows up to 3,100 m³ (680,000 imp gal)/day (the remainder maintains a flow in the short stream below the spring) from the spring and 500 m³ (110,000 imp gal)/day from the well. Despite using less than half the consented water, water meters are planned to be installed and operational by 2017. When last rated Raglan's water got a poor 'Ed' (unsatisfactory level of risk) rating, but work was done in 2014 to upgrade the quality.
