Using Groundwater Well to Water a Soccer Stadium Grass Pitch

Hi, I'm looking for some technical advice from anyone who has set up or maintained a sprinkler system for a football stadium where water is sourced from an onsite groundwater production well. The existing onsite well can deliver approx. 50 m3/day - space is limited at the site so not sure if large storage tanks would be feasible. Just looking for a ball park figure of how much water is needed on average to water a pitch during the summer months how long would a system run for (hrs). The site is located in the UK with Annual Average Rainfall being approx 950 mm. Can the sprinkler system be run directly off the pump (using pump pressure) without using storage? Thanks,  Patrick
