A man-made Hastings lake could be filled in as part of a $2 million Hastings District Council plan to better manage its industrial stormwater.
The amount of risk that Lowe's Lake posed to the region's drinking water was the subject of heated debate during 2019 local body elections.
The lake is part of the Heretaunga unconfined aquifer and is within the Frimley bore source protection zone. The district council-owned lake at 15 Hazelwood St is within 1km of 13 bores used for food processing, irrigation and drinking water supplies.
Concerns were raised earlier this year that nothing had been done after a June 2018 report to the Works and Services Committee identified the lake as a "potential risk to the Heretaunga Plains aquifer".
The lake also previously tested for high levels of E. Coli.
