The answer to water quality, quantity and allocation is water storage, Wairarapa MP Alastair Scott says.
And while Hawke's Bay waits to learn if the Ruataniwha dam will go ahead, Mr Scott told the Dannevirke News this project and a proposed water storage scheme in the Wairarapa need to go ahead.
"The environmental and social benefits of water storage are obvious. Maybe dairying, with the payout at around $4kg, [of milk solids] there may not be a big buy-in from dairy farmers but for other land use, such as seed growing, horticulture and viticulture, it makes sense."
Mr Scott who has an interest in a Wairarapa vineyard, said water allocation from stored water for hydroponics and strawberries would provide a valuable return per litre of water.
"The demand for water continues to increase, yet the supply is fixed, so it's time we accept the fact as fresh water becomes more and more valuable, it comes at a cost. This means we need tostart investing in water before it runs out.
